ODD AND SPECIAL EVENTS IN MY LIFE


  1. Prenatal memories
    in the mood

    In the Mood
     

    I had brief periods of consciousness in the womb:

    • I saw the color red.
    • I heard stomach noises.
    • My eyes opened briefly and I saw blood vessels.
    • I faintly heard part of the song "In the Mood" by Glenn Miller (dad's favorite song at the time).

    When I was born I did not like what I heard and saw (hospital tiled walls with awful echoes, PA calling doctors).

    When I was taken home, I heard the music again and it was much better.

    I did not have any recollection of these memories until a pro-life pastor suggested that people look for them.

    .....

    They had a nice set of gifts for the first baby born in the new hospital.

    Of course, I was the last baby born in the old hospital.


  2. Boob-tube baby
    Westinghouse TV

    My father was a television engineer for Westinghouse in Sunbury PA.

    There was no TV station near Sunbury.

    He was given a TV set (right) and asked to find out what was needed to get a TV signal.

    He created a tuned Yagi antenna to receive the station in Harrisburg 50 miles away.

    He mounted the antenna in the attic of our apartment building.

    We were the first family in town with a TV set.


  3. Where music comes from
    Westinghouse Radio

    We lived on the main street in town in a second floor apartment.

    One day when I was about 2, we heard music outside.

    Mom took me to the window and we watched a parade with bands and floats go by.

    The next day I heard music, and ran to the window to see the parade. There was nothing there.

    I asked mom "parade?" She said, "No. That's the radio." Then she showed me the kitchen radio.


  4. Sandy mess
    sandbox water

    We had moved to Indiana.

    My mother was studying for exams in extra classes she took to become a substitute teacher. So she wanted quiet.

    My father was at work. When a friend came over to play, mother told us to not play anywhere except in the sandbox.

    When we got to the sandbox, it was full of rainwater. The water was invisible from the window in the house.

    We went back to the house and said we couldn't play in the sandbox.

    We were told we would be spanked if we played anywhere except in the sandbox.

    So we got in the sandbox and got soaked. We played there for two hours.

    Finally mother came out and realized what happened. She said she was sorry, and took us to the porch to dry in the sun.


  5. My body doesn't work that way.
    indian style

    Indian Style
     

    In my kindergarten class, the teacher told all of the pupils to "sit Indian style" (a yoga position, as at right).

    I could not do it. My legs would not bend that way. The teacher tried to push my legs into that position and it hurt.

    The teacher then let me sit in a different way with my feet on either side of my hips (which many others can't do).

    I was born with rotated joints. All 4 of my major hinge joints (elbows and knees) are rotated 45° to their normal angles.

    • The normal alignment of all joints in the arm and leg is that the joint axes are all parallel to each other.
       The axes in my elbows and knees are turned 45° to the other joints.
    • A normal arm hangs with the elbow ready to bend forward and the thumb pointing at the leg.
       My arm hangs with the elbow ready to bend in front of the chest 45° and the thumb pointing at the leg.
       If I bend my elbow straight forward, my thumb rotates to point upward 45° toward the chest.
       When sitting at a table eating, I cannot hold silverware horizontally in the customary way. But if I stand or lean over, I can do it.
    • A normal leg has the knee ready to bend straight backward and the foot pointing straight forward.
       My leg has the knee ready to bend back and outward 45° and the foot pointing straight forward.
       If I sit with my legs bent down (by gravity), my feet point outward 45°.
       When I drive or ride a bicycle, my feet point outward. If I try to point my feet forward, my knees don't work right.
    • My velum (soft palate) is not long enough to seal, so I have a nasal voice and can't swim underwater without a nose clip.
    • I have stenosis (narrowing) of the helicotrema (low-frequency vent) in both inner ears. Infrasonic sounds are very painful to me.

  6. I was 5 when I was in the only fatal traffic accident I ever witnessed.
    stone hauling

    My mother was driving us in the kindergarten carpool.

    A stone-hauling truck ahead of us had mechanical troubles. It could not pull the truck up the hill.

    The truck's brakes would not hold the load of stone on the hill. It rolled backwards.

    The truck driver got out of the cab to put chocks under the wheels.

    The truck wheel ran over the driver, killing him (I didn't see this - I was on the other side of the car).

    The truck continued to slowly roll back until it hit the front of our car.

    Nobody in the car was seriously hurt. The front end of the car was smashed in.


  7. In a 1957 mass-immunization program, I got a vaccine that gave me allergies for the rest of my life.
    severe allergy 1957 Chevy

    They set up a mass-immunization site in 1957 in the school I went to kindergarten in. It was one of the first ever.

    Every child in the school was forced to receive two injections.

    My arm was swollen up to three times its normal size for three days.

    My allergist told me in 1986 that I probably got the early vaccines that did not have the virus growth media filtered out.

    He said I became immune to those media. So I am permanently allergic to wheat, eggs, soy, milk, and latex rubber.

    There was one consolation:
      My father ordered a new 1957 Chevrolet at the dealer that same day to replace the wrecked car (above).
      I drove it many years later when I learned to drive. We had that car 21 years.


  8. At age 5, I wondered why they don't make a record changer that always gets the record size right.
    old VM

    At my grandparents' house I got a kid's 78 version of Perry Como's "Round and Round." and wanted to play it.

    My grandfather had a V-M 407 record changer. It has 4 speed-size positions:

      45 7 LP 7 LP 10-12 STD

      These were 7-inch 45, 7-inch 33, 10-12-inch 33, and 10-12-inch 78.

      The changer could take 10-inch and 12-inch records intermixed.

    My father (F) and grandfather (G) got into a small discussion while trying to play it.

    (G) "Turn the knob here! It's a 78!"

    (F) "No, turn it here. It's a 7-inch record!"

    (G) "But that's 33!"

    (F) "We'll turn it there, then turn it to 78 once the arm sets down!"

    "PSSSSSSSSSSH!"

    (F) "Something's wrong, it missed the edge of the record!"

    (G) "Try the 45 position."

    "PSSSSSSSSSSH!"

    (F) "It still missed. This record seems too small."

    (G) "Let me get a ruler."

    ---- ---- ---- ----

    (F) "Turn it to 78. This is a 6-inch record. We'll have to play it manually!"

    I wondered why it could not get it right. But see items below on how to get it right.


  9. I was a wordsmith long before I knew what that word meant.
    spooter spootledop
    our typewriter

    A wordsmith is someone who invents words. Here are a few of my early ones:

     Spoot - The dull sound the end-of-line bell (inset) on our Underwood typewriter (right) made

     Centid - My thought-word for a half-full glass

     Dwet - The sound an organ makes at the end of Now I Lay Me on a record I have

     Blig - The sound an organ makes when very short notes are played.

     Plick - The sound of the process of cars choosing lanes on a (toy) road

     Postphone - Use a telephone to postpone a meeting

     Spootledop - I saw a tall red pole topped with a red disc to point golfers to the hidden green. This word came to mind.

     Sloke - slowpoke

     Sneakret - A sneaky secret (e.g. 'sneakret agent')

     Cliptomaniac - A kleptomaniac who steals only paper clips

     Misteak - A mistake within a mistake

    I have created thousands more since then.


  10. At age 5, I realized that traffic lights are green for different streets at different times.
    toy traffic light real traffic light

    A neighbor boy got a 3-foot tall toy plastic traffic light for his birthday (left).

      (I could not find a photo of the exact signal. The original one was white instead of black and the base was a rectangular box.)

    All of the lights the same color came on at the same time in all four directions.

      (This is because there was only one 15 watt bulb for each color shining through all four lenses. The yellow is on in the photo.)

    The round knob on the base selected red, yellow, green, or off.

    I realized that this had to be wrong. Traffic on each street is stopped so traffic on the other street can go.

    A real traffic light is shown at right.


  11. I didn't know where I had been.
    fallow garden strip

    A neighbor girl and I had been digging in a fallow garden strip that was similar to the one shown.

    I buried one of her toys and told her as a game to try and find it.

    Instead of trying to find it, she ran crying to her father, saying I hid it.

    My father told me to come to him. I got up and walked to where he was sitting.

    He then told me to go dig it up and give it to her.

    I started to run back to get it. Then I stopped. I had no idea where along the strip I had been sitting.

    If I had not walked to where he was sitting, I would have known exactly where the toy was.


  12. Saw a Dual 1004
    Dual 1004

    My father took us to one of his co-workers' house.

    The co-worker had just bought a new Dual 1004 record changer.

    This changer uses a feeler wheel in the tonearm to find the exact size of the top record on the turntable.

    The feeler wheel scans the top record on the turntable from inside to outside.

    I realized that this changer could take odd sized records intermixed in any size order.

    This was one of the very few changers ever made that could play that 6-inch record (above) automatically

      (but I would not know this until 1967 when I got access to a large Sams Photofact library).


  13. I experienced the turning on of a "device driver" in my brain
    first item I read

    We were studying Phonics in first grade in fall 1957 and we had just done the letter 'P'.

    I had been making a table on the mimeo handout we all got of all the sounds of all of the letters we learned so far.

    I woke up the next morning and saw words everywhere in the room where I had not noticed them the previous day.

    I automatically saw and read words on this comic book I got the day before (right). The first thing I noticed was "HONK".

      (Right click the image and choose 'View Image" for bigger version.)

    This driver also automatically gave me pronunciations and meanings of words I knew.

    Words have automatically read themselves for me ever since.

    My mind had created what computer people call a device driver that reads text. I am still using it. Words still read themselves.

    Apparently people being taught the Whole Language system do not form compact device drivers.

    I have several other device drivers in my brain, including math, geometry, locomotion, keyboards, and sound location.


  14. Colored rings attacked me
    flying rings

    Flying Hula-Hoop rings chased me through the yard and then tried to melt through my bedroom window when I was inside.

    The rings were (in the order they came) red, orange, yellow, green, blue, and violet, silent, and about 2 feet in diameter.

    They were coming toward me face-on in an undulating path (imagine an invisible worm wearing six colored belts).

    Then I woke up. It was a dream! I was about 8 years old at the time.

    What I want to know is how my mind came up with this when I had never seen anything even remotely like it.

    I also want to know how my mind knew that glass could melt. I never knew that before.

    I do note that the colors were the (now obsolete) pigment primaries and secondaries taught in lower grades in school.

    The colors were a learned portion of the dream.


  15. I was cheated out of a party game win.
    donkey game

    We were playing pin the tail on the donkey at a kiddy party.

    When it was my turn, I put the tail right where it belonged.

    Everyone screamed that I could see, so they made me do it again.

    This time I put the tail within 2 inches of where it belonged.

    They made me do it again. But this time they pointed me in the wrong direction after spinning me.

    I pinned it on the wrong wall. They counted this as my play.

    I had not been able to see in any of the attempts. I have a system in my head that figures location.

    I needed that system to walk in the dark between my bed and the light switch on the opposite wall.

    .....

    About that same time, I was in class and the teacher asked me to point to India.

    She wanted me to point to it on the map. But I pointed to where India really was on earth in relation to the classroom.

    .....

    I usually know where I am.

    When I was 10, my parents depended on me to guide them through freeway interchanges and keep track of car trip navigation.


  16. UFOs over the farm
    fire balloon or sky lantern

    This was at my grandparents' farm in Bridgeport IL.

    We saw a yellow-orange light about 30° up in the west. I thought it was possibly a missile test from a silo.

    Another red-orange light rose up from behind the trees. It changed to orange as it rose.

    Both went northeast. The first one moved north of me and went out.

    None of us had ever heard of a "UFO" at that time.

    My grandmother said, "Oh, them's just fire balloons sent up by teens over at Sumner."

    "They been doin' it all week. We used to make those when we were kids."

      (The fire balloon (or sky lantern) has been around a long time. The Chinese had them since the 14th century.)


  17. I heard two versions of the same tune in two days with different words.
    tickle bee ticklush ruben

    I first heard the ad for the Tickle Bee game on the TV. I was about 8 at the time.

    The next day, we went into the attic at my great grandfather's house on the farm.

    He had a very old wind-up-phonograph with a magazine type record changer.

    One of the 78 rpm records Dad put on it was "Ticklish Ruben" by Cal Stewart.

    I said "Hey! That's the Tickle Bee song! On TV!" He didn't know what I meant.

    The next day, the Tickle Bee ad came on again.

    I said "This is the song I meant yesterday. The song on that record."

    He still didn't seem to understand what I was talking about.

    I got a Tickle Bee game for Christmas that year.

    When I was in my 20s, I bought a copy of that record I found in a garage sale.


  18. He wouldn't believe the truth
    black tree sap

    I found black sap dripping from a tree during recess at school and used a stick to get a sample to look at.

    Another kid was looking at it and got some on her clothes. That evening her mother called my father about it.

    When my father asked me what it was (the girl said tar), I said it was sap.

    My father said "Sap is not black!" He threatened to spank me if I didn't tell the truth.

    I said repeatedly "Take me there and I will show you the tree." But he refused to believe it.

    I had to lie and say it was something else to avoid being spanked.

    I now know this gave wrong laundering information to remove the stain. But they wouldn't believe the truth.

    I have since seen black sap coming from wild cherry trees with weather damage (right). And alcohol removes sap.


  19. I found a circuit for a series/parallel photoflood dimmer box in 1961
    photo dimmer

    This circuit was published in the May 1961 Popular Science.

    This switchboard could brighten and dim either two or three photoflood lamps.

    It is SEPAR-302 in the booklet below

    It is the shown circuit below.

    This diagram is from the magazine.

    I found a different circuit for two lights a few weeks later.

    This sparked an interest in me for this kind of circuit. I started collecting and designing them.


  20. A brightly flashing object in the sky July 6, 1961
    ufo kite

    My father and I were coming home from a shopping trip in downtown Indianapolis.

    As he drove north on the highway toward our house, we saw a brilliantly flashing object in the sky far in front of us.

    It was apparently reflecting the sun and was flashing about 3 to 4 times a second.

    We lost sight of it behind trees when we turned into our neighborhood.

    Two days later, I got one for my birthday. It was a spinning kite similar to the one in this photo.

    The flashing was the sun reflecting on the silvered surface of the horizontal member twice per rotation.

    As shown in this photo, it spins clockwise.


  21. Almost total lunar eclipse August 26, 1961.
    1st eclipse

    I and my brothers were at home with a baby sitter while my parents were at some event. I was 10 years old.

    I noticed as I was making cartoon drawings that the moon was changing. A full moon had become like a crescent.

    I mentioned it to the baby sitter. She said I must be mistaken.

    I did not get to see the rest of the eclipse because she said I had to go to bed on time.

    I knew what an eclipse was, but did not know one was going to happen that day.

    It was in the newspaper the next day.


  22. Frank Edwards and I simultaneously saw the same UFO in Indianapolis on October 12, 1961
    f-e ufo

    But I didn't know this until 1996 when I analyzed his account of the sighting in his book.

    I do remember that there was a story of his sighting in the paper two days after his sighting, but it had no details.

    This story was the place I had first seen the term "UFO".

    1961 Frank Edwards Sighting

    It was close enough to me that I found out what it really was.

    The picture is my rendering of what I saw.

    The yellow lights appeared at the right end of the arc, moved slowly to the left, and went out at the left end.

    There were gaps between the lights at various intervals that moved with the lights.


  23. I knew more at age 10 than the engineer demonstrating record changers at RCA's open house exhibit
    rp-215

    He said that both the RP-215 and the new RP-218 could play all standard record sizes (7-inch, 10-inch, and 12-inch) intermixed.

    I showed him how the RP-215 cannot mix 7-inch records with other sizes because larger records hold down the 10-inch feeler.

    I told him to put a 12-inch record on the turntable.

    Then I asked, "Can the 10-inch feeler now tell whether a 10-inch or a 7-inch record drops next."

    The 12-inch record covered the 10-inch feeler (black rubber tip next to turntable), so it had to select 10-inch.

    This changer can take 10-inch and 12-inch records intermixed, or play 7-inch records separately.


  24. A vertical-takeoff rubber-band-powered airplane
    vertiplane

    When I saw a vertical-takeoff airplane in a magazine, I had to try out the idea.

    This airplane used huge wing flaps to redirect the propeller thrust downward to lift the plane straight up.

    My Flying Model Simulating the Ryan Vertiplane

    It worked better than I could imagine indoors. It jumped up into the air.

    Outside, a strong wind could flip it over on takeoff.


  25. I showed my art teacher the new primary colors at age 11
    old primaries old primaries new pigment primaries new primaries

    In fall 1962, my art teacher gave each of us a 4-color watercolor set.

    It had the old pigment primaries red, yellow, and blue, and a black for large uniform black areas.

    She then assigned us to mix watercolors on little plastic palettes for a color wheel.

    Then we were to paint patches of paint on paper for this color wheel.

    Then we cut squares from these patches and put them on the color wheel and labeled it (right).

    The problem was that the green looked black and the violet was almost black.

    The art teacher blamed this problem on the cheapness of this paint compared to oil paint.

    It is amazing that a new library book on the new color science was brought into our classroom that very week for reading.

    I learned the new color theory from that library book.

    This book had the primary colors for light (red, green, and blue).

    It also had the new pigment primaries (magenta, yellow, and cyan).

    Experimenting, I found that these new primaries worked much better than the old primaries.

    I showed the book to the art teacher.

    Two weeks later we got new paint boxes with magenta, yellow, cyan, and black.

    We redid the experiment and got beautiful color wheels (right).

      (The color wheels shown here are art software replicas, as I no longer have the originals. They were thrown out when my family moved.)

    Note that oil colors work differently because they can change color with the thickness of the paint. Watercolors can't do that.

    Question: 59 years later in 2021, why do I see art products and art classes still teaching the obsolete primary colors?


  26. My device to dye Easter eggs with multiple colors.
    easter eggs

    I used a small benchtop vice I had for modelmaking to hold up the dip loop provided in the Easter egg dye kit.

    The vice and dip loop held the egg in the dye cup so part of the egg was in the dye and part was not in the dye.

    I dyed eggs like the ones shown at right with it.

    I noticed that the dyes in the egg kit I used were the new pigment primaries and secondaries.


  27. Saw an Elac 16
    Elac 16 Bingo

    I was at a Cub Scout meeting when I saw the record player the host family had.

    This one used the pickup arm to scan the unplayed stack for record size from outside to inside.

    It has a size control for playing a single record with the short spindle.

    This played only the standard three sizes. It can't play a 6-inch record (above) automatically.


  28. A partial solar eclipse on July 20, 1963.
    2nd eclipse

    We were at my grandmother's house. I was expecting this one and was ready for it.

    I had built a sunscope for the occasion. This was a box with a pinhole at one end and a white screen at the other.

    You put it over your head and faced the screen, with the pinhole over your head pointed at the sun.

     DANGER: NEVER look at the sun through binoculars or a telescope. It will destroy your vision.

    I got to see the entire eclipse. It was total in Maine, but I was in Illinois that day.

    The diagram shown is part of one in that was the paper that morning.

    I kept looking for total solar eclipses close to where I lived for years. There weren't any until 2017.


  29. My working model of the GM HydraMatic™ automatic transmission at age 12.
    planet set hydramatic hydramatic

    I used Tinkertoys™, rubber bands, and wood parts I made myself to build a working model of the Hydramatic gears.

    The Hydramatic (and most other) automatic transmissions use planetary gears.

    Planetary gears have sun gears, ring gears, planet gears, and planet carriers.

    The parts I made are planet carriers (violet) and ring gears (green). Only one of the 3 gearsets I made (the middle one) is shown.

    (The parts were not really colored green and violet. I used the colors here to illustrate which parts are which).

    The planet carrier (violet) takes a shaft and shortest rods to hold two pulleys on opposite sides of a Tinkertoy spool.

    The ring (green) has a hole that just accepts a spool and two pulleys across its diameter (inset and in cross section).

    The ring is a square with the large hole in the middle and holes for four rods in the corners (two are shown).

    I put rubber bands (brown) on the pulleys to simulate gear teeth. They also had friction to act as the direct clutches.

    I used rods that could be moved in to stop certain parts to act as brake bands (yellow at bottom).

    I used rod bearings, rods, and a wood base to hold up the shafts (not shown).

    Since I had no way to simulate the hydraulic coupling, I left it out. The model shows only how the gears change.

    In the gearset shown, the power comes in on the red shaft and turns the sun gear (spool).

    The planet carrier turns the blue shaft to send the power on.

    In reduction mode, the ring is stopped. The planets (pulleys) roll around the sun to turn the planet carrier at a slower speed.

    In direct mode, the planet carrier and ring turn together (the rubber bands drag it) so everything turns at the same speed.

    A diagram of the real Hydra-Matic is shown at right.

    In the real transmission (right), disc clutches were used to couple the ring to the sun to turn them at the same speed.


  30. Croquet paths
    croquet paths

    To make play easier, we set the mower lower and mowed paths for the croquet balls to follow.

    We did this so grass would not deflect the balls.

    Originally, we just mowed the double diamond shape.

    Later we added the extra paths to make play easier and make location of the paths easier to calculate.


  31. The brother alarm
    brother alarm

    I was (and am) 6 years older than my oldest brother.

    My brothers kept messing with my stuff while I was at school, often breaking things.

    When we lived in Indianapolis, I had a key for my bedroom door so my brothers could not get in there.

    When we moved back to Bloomington, my room had a sliding door with no lock.

    One of my brothers broke my radiometer, so I needed a way to protect my things.

    I tied a suitcase tag to a small bell and several sleigh bells, ending with a long string.

    I tied the other end of the string to one end of the door lintel.

    To set the alarm, I stood on the outside of the door and shut the tag in the door up high.

    If the door opened while I was at school, the bells would fall and ring as they banged on the doorframe. This called my mother.

    My brothers were not tall enough to reset the alarm.


  32. Making a booklet of series/parallel switch boxes
    photoflood s-p

    I had become interested in several different published ways I had found (and a few more that I had devised)
    to make switchboards that select between series and parallel operation of lamps.

    I compiled these into a booklet in 1965.

    These circuits are on the web page Simple Series and Parallel

    The booklet contained all of these circuits that are on the web page:
    SEPAR-201, SEPAR-202,
    SEPAR-300, SEPAR-301, SEPAR-302, SEPAR-303, SEPAR-305, SEPAR-330,
    SEPAR-400, SEPAR-401, and SEPAR-402A.

    The identifying numbers for these circuits are mine. I coined them for the booklet. SEPAR-302 is shown.


  33. My brothers and I independently discovered the Scary Flashlight Face
    flashlight face

    It was Halloween and all of us were given new flashlights for safety on the street.

    After trick-or-treat, we were in the front entryway of the house.

    There is a large mirror on the wall opposite the front door.

    The lights were out and we came in with our flashlights on.

    Someone asked where I was, and I pointed my flashlight up at my chin.

    The flashlight on my face from below momentarily scared one of my brothers.

    Then we all started doing it while looking in that mirror and laughing,

    Only many years later did we find out that the Scary Flashlight Face was a gag used in silent movies.


  34. Saw my first Collaro Conquest
    collaro conquest

    I was in a record store and wanted to hear a 45 rpm record to make sure it was the right one.

    The salesman put it on a Magnavox player similar to the one shown.

    I was amazed at how the pickup arm tip measured the record stack for exact size from outside to inside.

    It was even more interesting how it felt for a record size, didn't find a record, and shut itself off.

    I immediately realized that this changer requires a pyramid stack of records (larger below smaller).

    Many of these can play that 6-inch record (above) automatically.

    This was the day I became quite interested in record changers.


  35. I designed a working traffic light at age 14
    poker chip cam tee intersection

    I built the 3-way signal head for a Tee intersection with a green left-turn arrow for the turn into the stem of the tee.

    I made a frame for a 1 rpm motor with a long shaft and for a set of microswitches mounted on the frame.

    I designed cams using poker chips, intending to by glue bushings to the centers of the chips. The cams would have changed the signals.

    Microswitches would feel cam edges. Two identical cams (yellow and red shown) put back-to-back can adjust the width of the active slot.

    Two microswitches would work each set of signals. One chooses red when inactive. When it is active, the other chooses green or yellow.

    The movements with the green left-turn arrow on are shown.

    I didn't finish this. I used the motor to make a color filter wheel instead.


  36. My mother and father used to make up silly sayings to keep us amused on long trips and at other times.
    dog rider

    Here are a few of them:

    • "There's no news like a dead horse."
    • "Always dry your feet before kicking a harp."
    • "If it weren't for Illinois and Ohio, Indiana would cave in."
    • "Who put termites in the Lincoln Logs?"
    • "There goes Mickey Rooney riding into the sunset on a police dog."
    • "Goofy is the only guy I know of who can fall up the stairs."
    • "Want to have a peanut butter fight?"
    • "They aren't gooderies, they are badderies. They're dead."
    • "If I had a hammer, I'd probably hit my thumb."
    • "If you won't smile, then snile."
    • "You need a little pix of pinchie dust."
    • "We are going to clown brownty."
    • "I'm cocoa for cuckoo puffs."
    • "Which end of that dog is the head?"
    • "I tiddled my lids" (After mother put the mayonnaise lid on the salad dressing and dropped the salad dressing lid in the mayonnaise).
    • "Isn't that down by the stove dump?" (a place where many kitchen stoves were abandoned).
    • "Ferryboat Godfather" (my father with his pop-up stern light for his boat - looks like a magic wand).
    • "Twilight Toads" (My father reassembled the steel frames for kitchen chairs with the seats upside down to paint them. They looked like giant toads.)
    • "Tree Kit" (My father cut up a fallen tree into firewood-sized pieces, leaving them where they fell. He called it a "tree kit".)
    • "Hide the donuts before Old Fishfingers gets into them."

  37. Rumble in the night.
    can express

    People would hear loud rumblings in the dark at our house on Sunday evenings.

    I had discovered that I could put a trash can on the front of my skateboard, get on the back end and ride it.

    I rode the cans down the sloped driveway to the street to be collected the next morning. I made one run for each can.

    The next day I rode the board down, put an empty can on, got on behind, and pushed with one foot to ride it up to the carport.

    I also used the skateboard to move baskets full of raked leaves.


  38. A six-volt neon sign
    6 volt neons

    I found a way to light up a small neon sign with a 6-volt battery.

    All you need are the battery, a switch, a relay, a capacitor, an auto spark coil, and the neon tube.

    I tried different capacitors and chose the size that gave the best result.

    I also used this circuit and a larger capacitor to make a strobe light with a small fluorescent bulb.


  39. Saw an Elac 9
    elac pw-9

    I was at a Christmas party, and this record changer was playing records.

    I noticed that the arm was not swinging out all the way between 45s.

    The teen who was running it said, "That's how it checks the size."

    This was like a Collaro (above), only the scan was from inside to outside.

    It scans the underside of the stack looking for record edges.


  40. I modified an RCA RP-215 record changer in 1968
    215 rep 215 mod

    I added antiskate, single-play repeat for all record sizes, full manual operation, and a stop command.

    Because the arm is an underhang arm, the antiskate works backward to normal antiskate.

    It repeats one record on the turntable over and over if the overarm tip is placed over the record rim (blue numbers).

      (A lever I put on the overarm shaft moves the 12-inch drop feeler when the overarm moves toward the rest post.)

    Hold the control in REJ until the arm stops swinging out to make the changer shut off now.

      (A link I put on the reject control activates the auto-shutoff lever as though the overarm activates it by being low.)

      (This link is active only when the control is in the REJ position.

    To return the arm to rest without turning off power, hold the control in the REJ position until the arm sets down.

    For full manual operation:

    1. Set speed to N
    2. Select ON - Turntable will not turn
    3. Move arm in as far as it goes, then back to the rest post
    4. Rotate the turntable backward at least two turns
    5. Select the speed - Turntable will rotate
    6. Place the arm where desired
    7. Changer will not trip at the end of the record.

    To return to automatic operation, use REJ

      (To add full manual, I cut off the position trip boss on the velocity trip pawl.)

    • As I repaired various record changers, I noticed how various devices behave.
    • SIZE KNOB - Manual control of record size
    • TURNTABLE - Feelers in the turntable
    • DISC DROP - Record is felt while it drops
    • STACK FEEL - Unplayed stack size is felt
    • DISC ALONE - Feels record while separated from others
    • TABLE TOP - Feels only top record on turntable
    • TONE ARM - The feeler must be in the pickup arm
    • SIZE SAVE - Size is remembered or set by repeat control
    • no - Does not work
    • OK - Can work
    • YES - Works alone
    • REQ - Required
    • Pt1 - Requires a Pt2 to work
    • Pt2 - Requires a Pt1 to work
    • Nx= - Next record must be same size
    • − - Does not apply
    • † - Requires speed intermix device

    I also discovered just how hard it is to make a record changer with all of the following features:

    1. plays odd sizes
    2. plays randomly intermixed sizes
    3. repeats any record in the stack
    4. plays a single record already on the turntable
    5. doesn't touch the grooved surface of the record

    Dual 1003, 1004, 1005, and 1006 do the first 4 at the expense of touching the record surface.

    Collaro TSC-640 does 1, 3, and 5, and plays arranged intermix (larger records before smaller).


  42. I suddenly changed my career choice in my senior year in high school.
    4K IBM 1130 computer

    My original choice was traffic engineering (part of civil engineering).

    Then I got hands-on experience with computers. I used a CDC 3600 and an IBM 1130.

    The photo shows an IBM 1130 that had 4 K of memory. The memory module was the size of a refrigerator and is not shown.

    I totally changed what I wanted to do. I now wanted to program and work with computers.

    In my working life, I programmed computers, built computer and laboratory equipment, and taught computing and math.

    I still occasionally had something to do with traffic engineering.


  43. The UFO detector
    ufo detector

    A magazine about UFOs had a project for building a UFO detector.

    It is essentially a magnetic field detector. If the compass needle deflects, the bell rings.

    I built one, and was actually more interested in it for protecting my music tapes

      (Magnetic fields can erase tapes and discs).

    It detected everything except a UFO.


  44. My wet-show device for a light show that makes colors from clear water.
    wet show wet show

    A pie plate or cake pan of clear water is placed on the stage of an overhead projector.

    My filter device (inset) is placed in front of the objective lens so the light goes through it.

    The projector is aimed at a screen or whatever the light is to be played upon.

    Agitate the water in the plate by shaking the plate. Colors appear on the screen.

    Squirt water in the plate with a squirt bottle or eyedropper.

    Put an Alka-Seltzer in and let it fizz.

    Sloped surfaces from ripples bend the light to pass through only part of my filter device.

    I later found a way to make a similar effect without water, using two clear plastic corrugated produce trays.


  45. I encoded a set of sound effects and floating voices in matrix quadraphonic for a stage play
    dynaco diagram dynaco decode

    Quadraphonic Mixing - 1971 Stage Play

    I used the Dynaco Diamond (DD) system.

    This could possibly be the very first creation of such matrix quadraphonic effects for a stage play.

    The mixing was actually done in late 1970, with a few edits in 1971.

    I also built the decoder for the auditorium (right).

    It required only one stereo amplifier and a stereo tape recorder.

    The sound effects and voices were quite effective.

    My encoding method would later become how I encode surround sound with standard mixers (way below).


  46. Using Poincaré's energy sphere to show phase relations in quadraphonic matrix systems.
    Poincare oblique view Pioncare isometric view
    Poincare side view Dolby Surround Stylus vectors Regular Matrix Stylus vectors
    Poincare side view for SQ SQ Stylus vectors 4-corners SQ Stylus vectors
    • Henri Poincaré devised this sphere to plot all possible relationships in polarized light.

    Léon Foucault used the sphere to plot all possible swinging paths of a pendulum on a rope.

    I learned about the Poincaré sphere in physics class.

    The Poincaré Sphere showing phase relations and phono stylus motions is in the diagrams at right,

    The following are the six orthogonal modulations defining the Poincaré sphere.

    - All modulations are on the surface of the sphere.

    - The colors in this list apply to only the upper two rows of diagrams.

    - Points on the far side of the sphere have large dots here.
    - Points on the near side or the limb have small dots here.

    - Horizontal (in-phase or mono) is at the right of the sphere (olive);
    - Vertical (180° phase) is at the left (violet).

    - The left-channel diagonal (cyan) is centered on the sphere's far side.

    - The right-channel diagonal (red) is centered on the sphere's near side.

    - Clockwise motion (90° L>R) is at the top of the sphere (black).
    - Anticlockwise motion (90° R>L) is at the bottom of the sphere (brown).

    Top Row: Left diagram is an oblique projection of the sphere.

    Top Row: Right diagram is an isometric projection of the sphere.

    Middle Row: Left diagram is a projection of the sphere from the right channel side viewpoint.

    Middle Row: Upper right image shows the stylus motions in the record groove for each orthogonal signal.

    The spheres and stylus diagram listed above also show the Dolby Surround matrix system.

    The Dynaco Diamond matrix also has the same Poincaré sphere that Dolby Surround has.

    Any quadraphonic matrix system encoded to records or other 2-channel media fits on the Poincaré sphere.

    The colors shown in the diagrams listed below do not correspond to the colors in the list above.

    The colors for positions below are red = R, olive = F, cyan = L, and violet = B.

    The added colors for below are yellow = RF, green = LF, blue = LB, and magenta = RB.

    Middle Row: Lower right image shows the record groove stylus motions for Regular Matrix signals (e.g. Sansui QS).

    Bottom Row: Left diagram is a right-side projection of the sphere showing the Columbia SQ matrix.

  47. I invented a secret cypher that cannot be broken without special knowledge.
    IBM punch card

    I had an idea to use the bit patterns in either punch cards or ASCII for encoding.

    ENCODING:

    I made a table of the 26 capital letters in the English language.

    I used a keyword to make two lists of 13 letters each.

    For each character in the original message, do the following:

     Separate the 7 bits in the character code (in ASCII) into individual bits.

     For each bit, select one capital letter from the lists.

      If the bit is a 0, randomly choose a letter from the first list

      If the bit is a 1, randomly choose a letter from the second list

      Add the new letter to the cyphertext output.

    Save the cyphertext output as a file and send it.

    DECODING

    Use the keyword to make the same two lists of 13 letters.

    For each group of 7 letters in the cyphertext:

     For each letter in the group:

      Find which list the letter is in.

      Make a 0 or a 1 depending on which list the letter is in.

     Combine the 7 bits into an ASCII coded character.

     Add the new character to the plaintext output.

    Save the plaintext output as a file and read it.

    The special knowledge is knowing that this system was used. If so, breaking the keyword is not too hard.


  48. Deriving an equal-separation 4.8 dB matrix with Poincaré's energy sphere.
    Poincare side view UQ UQ Stylus vectors SQ-blend Stylus vectors
    • I used Henri Poincaré's sphere to derive a max separation quadraphonic matrix.

    My purpose was a matrix with equal separations between any channel and the other three channels.

    I achieved a separation of 4.8 dB (QS has a 3 dB adjacent separation and infinite diagonal separation.

    The colors for positions below are red = R, olive = F, cyan = L, and violet = B.

    The added colors for below are yellow = RF, green = LF, blue = LB, and magenta = RB.

    The left diagram is a right-side projection of the sphere showing my UQ matrix.

    The upper right image shows the stylus motions in the record groove for the UQ matrix.

    Columbia said to use a 10% front blend and a 40% back blend if no separation enhancement is used.

    The lower right image shows the stylus motions in the record groove for this similar blended SQ decoder.

    Later I found out that Peter Scheiber had made these calculations before me.

  49. I built a passive matrix decoder that decodes Regular Matrix (RM) records.
    quad diagram RM speaker matrix

    It was easy to build a fully adjustable passive Regular Matrix quadraphonic decoder.

      (Right click the image and choose 'View Image" for bigger version.)

    Only a two-channel stereo amplifier is needed.

    I used a design similar to the back speakers of Dynaquad except for the DEPTH control.

    I used a simple blending circuit for the front speakers using the WIDTH control.

    This is placed between the output of the two-channel power amplifier and the speakers.

    This can be adjusted to decode any of the Regular Matrix systems.

    It can play QS, EV, DQ, DD, and Dolby Surround.

    The parts were easily available at the time. But now the rheostats have become scarce.

    I make the new versions with 8-ohm L-pads because I can get them.


  50. I have a Run-in with Yellow Trap
    yellow trap seen

    I was turning left and my signal turned yellow, then red. I was in the intersection and waited for oncoming traffic to stop.

    What I didn't know was that the oncoming signal remained green. The line did not stop. This is yellow trap.

    I saw that this was a hazard and wrote the state highway department about it.

    They wrote back and said they made a device for that signal to prevent the hazard.

    But it didn't work. I still saw yellow-trap events at that signal.

    I called it "lag-trap" at the time because it happens with lagging left turn phases.

    DANGER: NEVER assume that oncoming traffic has the same color signal that you have.


  51. Taught myself how to sail and built a windicator.
    windicator my sailboat

    I had previously read about sailing. A basic sailboat has three control surfaces:
     - The keel or centerboard, the rudder, and the sail.
     - They act together to propel and control the boat.

    We went to a cabin on a lake for vacation (mostly so my father could fish).

    We found a little sailboat on the back porch. We received permission to use it, and I tried it out.

    Within a week, I had fully learned to operate it and was whizzing back and forth across the lake.

    I built a device that clips onto the centerboard and indicates both wind and compass direction.

    The wide end of the wind vane stuck up 2 inches above the dials so the wind moved it.

    We went back to that same cabin two more years.

    The second year we found out the owner had died. The heir sold me the sailboat.

    I had the sailboat for 20 years (right). I finally sold it because I had no vehicle that could transport it.


  52. I modified my Collaro TSC-640-200 Conquest record changer over 1972-1985
    collaro TSC-640

    I added a magnetic cartridge, antiskate, cueing, arm range, size range, turntable stop, and autospeed.

    Improve a Collaro TSC-640

    This is closer to a record changer that always gets the size right (see above), but not quite.

    It always gets the size right if the records are stacked in pyramid order.

    Pyramid order is arranged intermix (larger records below smaller records).

    Turntable stop stops the turntable during the change cycle so the records don't slide on each other.

    Autospeed also lets it play a stack with large 33s followed by small 45s (as shown).

      (The brass arm near the overarm shaft works Autospeed for arranged intermix.)

    Repeater discs (above) work in a stack if the records above and below a repeater are the same size.

    Yes, it can automatically play that 6-inch record (above). The arm feels the exact size (as in photo).

    The cue control is at the right edge of the photo just behind the automatic knob.

    I got this changer in 1970. It is still the turntable I use.


  53. A "real" UFO
    ufo by sun

    I was sailing my boat (see above) on Monroe Reservoir when I saw a very bright light to my right (west).

    The light seemed to be like a star in size, but it was as bright as the sun (which was near the object in the sky).

    Other boat traffic appeared from under a bridge and I turned my head to look for possible collision paths.

    When I looked back, the object was gone.

    Remember that UFO is the acronym for Unidentified Flying Object. It does not mean aliens.

    I am sure the sun was reflecting from some object in the sky. It is unidentified only because I don't know what was really there.

    This picture is an artist's conception.


  54. I added passive matrix varying to the passive matrix decoder for Regular Matrix (RM).
    RM autovary matrix

    I modified the fully adjustable passive Regular Matrix decoder.

      (Right click the image and choose 'View Image" for a bigger version.)

    This is still placed between the two-channel power amplifier output and the speakers.

    I added the Autovary function to narrow the back separation with heavy front center sounds.

    The lightbulb increases its resistance by 8 to 10 times when hot.

    When the lightbulb is cold, the separation between the LB and RB channels is wide.

    When the lightbulb is hot, the separation between the LB and RB channels is narrow.

    When the lightbulb is cold, the separation between FC and the back channels is low.

    When the lightbulb is hot, the separation between FC and the back channels is high.

    This can still be adjusted to decode any of the Regular Matrix systems.

    It can still play QS, EV, DQ, DD, and Dolby Surround.

    To turn off Autovary, set the Autovary control to minimum resistance.

    Adjust Autovary to produce a just noticeable change in back separation with front sounds.


  55. It IS balloon!
    IP balloon the balloon

    One day we were having lunch at our house when our dog Penny started barking, and then howling, straight up.

    Then a loud ROAR! I ran outside. A hot air balloon passed very low over the house (actual balloon in right photo).

    I heard the pilots remarking about the croquet paths we had mowed in the grass (item above).

    I learned two things: How big the balloon really is, and how loud it can be.

    My title for this entry comes from a line from the TV show F Troop.

      (This is the likely solution to the 04/24/1964 Socorro NM UFO Sighting - inset.)

      (Inset balloon is an artist's rendering.)


  56. My favorite April Fool pranks:
    drawer

    When I do April Fool pranks, I never do anything that can damage or ruin anything.

    I was a college student that year, so I didn't have time to do anything elaborate.

    For a prank on my mother, I took three of the kitchen cabinet drawers out and put them in the wrong cabinets.

    For a prank on my brother, I put a card saying "April Fool" on his guitar, but did nothing else.

    Just before I had to leave for class, mom came into the kitchen and discovered the drawers in the wrong places.

    When I got home, I found mom putting the contents of one of the drawers in a box to move them.

    She said she didn't understand how I was able to move the drawer contents so quickly.

    I then realized that she didn't know that the drawers could be taken out of the cabinets. I said, "I took the drawers out."

    Then I showed her the button you push to unlock a drawer (black, at left back of drawer image).

    Then I quickly took the drawers out and put them back in the places where they belonged.

    I had to go to class again. When I got home, I found my brother had been frantically searching for what I did to the guitar.

    He said "What did you do to my guitar?"

    I said "I just put a sign on it. You played the rest of the prank on yourself looking for what I didn't do."


  57. Music from a microprocessor in 1977
    Star wars theme

    The last assignment in my digital logic and microprocessors class was to do something linking the computer to the real world.

    Of the many suggestions in the assignment was to use the computer to play music.

    The text suggested using an output port to feed a digital-to-analog converter, which then runs a voltage-controlled oscillator.

    After experimenting with these devices, I found that the 8-bit D-to-A converter lacked the resolution for tuned music notes.

    Several others experimented with this and got awful out-of-tune tones. I decided another method must be used.

    One day I hooked up my circuit, put in my program, and started the computer.

    Out of the speaker came the theme to Star Wars in single notes (no chords) in perfect tune.

    I used the D-A converter to set the volume for each note, and used loops in the program to generate the pitch.


  58. I designed and built the Double Ball Gulfstream II pinball machine modification in 1978.
    Gulfstream II

    I put myself through college fixing pinball machines and video games for an arcade company.

    The design was also another product from that digital logic course (above).

    I turned a machine that brought in 75 cents a day into the third highest paying machine.

    It had two eject holes that just kicked the ball back.

    My modification made it keep the first ball that went in and give a free ball at the shooter.

    When both balls were in the holes, they both ejected at the same time.

    This page shows how it was done: Double Ball Gulfstream II


  59. My modification of my PE-2038 record changer in 1978
    repeat disc PE-2038b

    I added the blue REPET position to the command lever (shown).

    This position causes the already playing record to play again after it finishes.

    I added the ability to use repeater discs in the stack (shown).

    Placing a repeater disc in the stack causes the record under it to play twice.

    Otherwise the changer behaves as though these changes were not there.


  60. I built a passive matrix decoder that decodes SQ.
    SQ speaker matrix

    It is easy to build a passive Regular Matrix decoder. I wanted to see if a passive SQ decoder could be done.

      (Right-click the image and choose 'View Image" for bigger version.)

    This is a quadraphonic decoder that goes after a 2-channel power amplifier.

    I had lucked out at an auction and won several large cartons filled with electronic parts at a very low cost.

    In those cartons were two large transformers with dual 8-ohm windings. I used them for the ψ (psi) phasors.

    Also among those parts in the cartons were all of the inductors in these circuits.

    I used an oscilloscope to tune the 8-pole ψ phasors for 90° from 15 Hz to 20 KHz (right).

    A switch selects between no phase shift, 90° phase shift, and SQ decode mix.

    The rest of the decoder is basically the UQ-1 decoder (above).


  61. Text-listing readable machine language

    Push Imed 0001
    Pull Intd 0004
    From Imed 0001

    Step Imed 0001

     ×  
    Push Intd 0003
     =  
    Pull Intd 0004
    Next Intd 0003

    I had an idea on how to make a computer with machine code that can be read as a text file.

    Each of the operation codes for the computer spelled a word or abbreviation with 4 ASCII characters.

    Executing any code that did not spell something the CPU knew would have made the computer end the program.

    Symbols surrounded by spaces would have been mathematical operators.

    Data references would have been hexadecimal numbers relative to the data area.

    This could have made computer bugs and viruses easy to spot. This picture shows how the text would have read.

    I actually bought some materials to make this, but the pressures of life in this world kept me from making it.

    Once the computer world had centered all efforts on Intel and Motorola microprocessors, this idea became moot.


  62. They gave me the wrong diploma at commencement.
    computer football

    When I graduated from college, I went through the line and got a diploma.

    When I got it home I looked at it.

    Instead of my Bachelor of Arts in Computer Science, I got a diploma for a Bachelor of Arts in Physical Education.

    Someone with the same name as mine got a BA in PE, but didn't go to commencement. So they gave me his diploma.

    So would I have to teach computers to play sports (right)?

    No! A trip to the Registrar's office the next day straightened it out.

    But it was prophetic. I later became the lab engineer for the Kinesiology (Physical Education) department for 13 years.


  63. In a near-death experience I saw hades.

    hades

    I almost died due to an exposure to latex rubber in interior wall paint.

    At the time, I did not know that I was allergic to latex.

    While I was unconscious, I saw the entrance to hades. It was at least 5 times as wide as it was high.

    Beyond the entrance, it was terribly crowded and loud.

    I woke up choking for air. That day I started studying so I would never see it again.

    A little over 8 months later, I did the ONE THING that achieves that goal.


  64. While tutoring finite mathematics, I became an expert on the subject.

  65. A book (fiction) that contains a surprising number of my life experiences
    The Revolving Boy

    The Revolving Boy by Gertrude Frieberg, published 1966

    I got the book sometime in late 1984.

    It contains striking parallels to the following events in my life:

    • Usually knowing where I am and which way is north
    • Knowing how to navigate to any destination (above)
    • The pin the tail on the donkey event (above - except he won the prize - I didn't)
    • Locating the direction of a country on earth relative to where I am (above)
    • Surround sound hologram (chapter 21)
    • Built devices to transpose music
    • A robot-steering game* using one-foot-square floor tiles - I used it to teach vector and GWBASIC graphics
    • I taught permutations and combinations (above)
    • I worked in chemistry labs
    • I used, taught, and wrote programs to calculate Fourier transforms (below)

  66. Croquet pants
    croquet pants

    Blair is a company that sells clothing by mail-order.

    My brother and I were looking at a Blair clothing catalog.

    We found a pair of golf pants made of cloth having the print pattern seen at right.

    My brother said "Those aren't golf pants! They're croquet pants! They match the stake at the end!


  67. The different long-scale and short-scale number naming came to my tutor sessions:
      three-rail billiards
    VALUESISHORT SCALELONG SCALE
    103KiloThousandThousand
    106Mega MillionMillion
    109GigaBillionMilliard
    1012TeraTrillionBillion
    1015PetaQuadrillionBilliard
    1018ExaQuintillionTrillion

    One of my students was from Spain, and could not comprehend the US federal budget in trillions of dollars.

    Spain uses the long scale with one trillion = 1,000,000,000,000,000,000. = 1018.

    I explained that Spain uses long-scale number names, while the US uses short-scale number names.

    The US uses the short scale with one trillion = 1,000,000,000,000. = 1012.

    The two number systems can be found here (and partially at right).

    To avoid confusion, use the metric (SI) prefixes.

    Each prefix always means the same value anywhere on earth.

    Incidentally, the game "billiards" is named after the long scale number name:
    one billiard = 1,000,000,000,000,000. = 1015.
    They said there were billiards of possibilities in three-rail billiards (image right).
    That would be quadrillions of possibilities in the short scale.


  68. My derivation of the only existing totally fair voting system in 1987
    fair elections

    At the time I was tutoring finite mathematics at the university to help struggling students.

    I was teaching about disjoint events (can't happen together) and independent events (don't influence each other).

    One student asked me if votes in our elections were independent events.

    I said, "No they are disjoint events. The same voter can't vote for two different candidates for the same office."

    This started me thinking of how the disjoint Plurality Voting System (vote for only one) really works.

    I noticed the disjoint Plurality Voting System's built in bias that favors the candidate most unlike the others.

    I started playing around with independent events instead of disjoint ones.

    From this I devised the totally fair Independent Voting System (vote each candidate separately).

    It is totally fair no matter how many candidates run for an office.

    Now how do we get the politicians to use it? They won't see the faults in the Plurality Voting System

     (or they like the idea of using the faults in the system to cheat).

    They chant "One man - one vote!" as justification to use a defective Plurality Voting System.

    It should be "One man - one vote per candidate!" for the Independent Voting System.

    It is impossible for the voter to cast an invalid Independent Voting System ballot.

    No primary election is needed with the Independent Voting System.

    Negative campaigning does not work with the Independent Voting System.

    The Independent Voting System is much harder to cheat.


  69. Huge number calculations
    how many grains

    This started when someone gave me a Rubik's Cube.

    I became interested in how to count and find probabilities on a Rubik's Cube.

    I wrote a computer program that could compute using very large numbers.

    My current version can work to 297 digits.

    I wrote it to do plus, minus, times, divide, power, factorial, permutation, combination, and recombination.

    Sample calculations - my favorite huge numbers:

    1. Tribbles in the grain storage bin - deriving what Spock said on Star Trek ("the Trouble with Tribbles").

       Spock said a litter of 10 every 12 hours for 3 days.

       Since the parent survived, that makes 11 times as many tribbles each time.

       11 ^ 6 = 1,771,561

    2. 5-card hands in a deck of 52 cards (4 suits of 13 ranks).

      This is the number of combinations of 52 items taken 5 at a time.

       C(52,5) = 2,598,960

    3. Grains on a chessboard - one grain is on the first square, each next square is twice the previous square.

       This is 2 ^ 64 - 1

       18,446,744,073,709,551,615

       = 1.845*10^19 - 1 = 1.845E+19 - 1

      The picture shows the piles up to square 11 (which is 2 ^ 10 = 1024). After that, the squares are too small.

    4. Indianapolis 500 possible finishing orders of 33 cars

       8,683,317,618,811,886,495,518,194,401,280,000,000

       = 8.683*10^36 = 8.683E+36

    5. Rubik's Cube
      rubic cube

       This is 8! * 3 ^ 7 * 12! / 2 * 2 ^ 11

       43,252,003,274,489,856,000

       = 4.325*10^19 = 4,325E+19

       There are 12 ways to assemble a fallen apart Rubik's Cube. Eleven will not solve to the START position.

    6. Rubik's Picture Cube

       This is 8! * 3 ^ 7 * 12! / 2 * 2 ^ 11 * 4 ^ 6 / 2

       88,580,102,706,155,225,088,000

       = 8.858*10^22 = 8.858E+22

    7. NCAA basketball tournament finishing orders with 68 teams if played fair

       This is 68! (68 factorial)

       2,480,035,542,436,830,599,600,990,418,569,171,581, 047,399,201,355,367,672,371,710,738,018, 221,445,712,183,296,000,000,000,000,000

       = 2.480*10^96 = 2.48E+96

      To play it totally fair would require 2278 games in a round-robin tournament.

      With the unfair way it is played, 68 teams play on a tree with 67 games, plus one more game for 3rd place.

       This is 2 ^ 68. The diminished number of possible outcomes is:

       295,147,905,179,352,825,856

       = 2.95*10^20 = 2.95E+20


  70. Sports tournament brackets are unfair
    braaaacket

    This kind of sports tournament is inherently unfair unless only the winner is awarded a prize.

    I used the same finite math methods I used to design the only totally fair voting system (see above).

    See the above NCAA calculation (above) to see how unfair it is.

    I noticed the following properties:

    • No team in the half of the bracket the winner is in can take second place.
    • No fair method is easily found to determine third place.
    • I noticed that double elimination could not be fair when I had to play the same opponent twice in one contest.
    • Finite mathematics shows that a round-robin type tournament is the only fair kind of tournament. But they require too many games.
    • They use seeding to try to keep the best teams apart until the end. But it is guesswork.
    • Reporters prefer bracket tournaments because there is a build-up to a climax in the final game that the reporters sell papers with.
    • Reporters hate round-robin tournaments because there is no climax. Nobody knows who will win until all of the games are played.
    • They would rather have unfair tournaments than fair ones so they can sell papers with hype.

    If brackets must be used, then do not award places other than first place.


  71. A pink star
    pink star

    I was walking out from the house to the car when I saw a pink star in the sky (image is simulated).

    Since this was very unusual, I went back inside and asked my father to come look at it.

    As we watched it, the star became darker, more purple, and larger.

    It then stretched in the east-west direction to about 5 times as long as it was wide.

    A green glow then surrounded the center of the original position of the star.

    We decided that it was something that had been launched in a rocket.

    It continued to spread out and faded to invisibility.

    I called the university Astronomy Department the next day to ask what we saw.

    They said it was a barium cloud - a solar-wind experiment released by a satellite.


  72. A magic doorbell
    motion detector

    My house has such twisty paths inside that it is impossible to hear a knock at one door from the other end of the house.

    I had the idea of using the x-10 remote control system to signal that people were at the door.

    I gave each x-10 motion detector its own address, and gave the output signal the address 3 spaces higher.

    Each output signal worked a receiver that rang a signal bell system and lit signal lights indicating which door.

    Visitors were announced before they ever touched the door.

    I am now contemplating using new motion detectors and transformers to run the signal system.

    The original system failed because the power company started using the same frequencies to read meters.


  73. I Invented the Surrfield mic
    Surrfield mic

    I set up this three mic design as shown as an experiment to record a solo vocalist and try to capture room reverberation.

    I fed these into a simple mixer with the S mic feeding the L and R channels in opposite phase.

    The soloist was about two feet from the L and R mics.

    The soloist practiced the part a few times before the first take. Then we recorded the take.

    I rewound the tape and played it through stereo monitor speakers. Then the following conversation took place:

     Me: "Would you please stop practicing? I want to hear the tape."

     Soloist: "That's not me. It's the tape!"

    It sounded so real that I didn't realize it was the tape playing. I thought it was the soloist practicing again.


  74. Solving the 11/09/1965 Northeast Blackout
    substation power factors correction pole caps

    On November 9, 1965: I saw the news story on the New England blackout on TV.

    In 1966, the Federal Power Commission report specified that relay Q29BD had tripped.

    They did not find a definite reason for the trip.

    They said possibly a sudden surge momentarily raised the power above 375 MW.

    The object near the ground in the foreground of this picture is one such overwattage cutout relay.

    The power was restored with the same equipment that was running at the time of the failure.

    In 1969, I bought Scientific Study of Unidentified Flying Objects."
     It has part of this report and an IEEE Spectrum report.

    In my engineering job in 1983, I built a monitor to find instantaneous campus electrical power usage.

    This power is measured in three components (right):

    1. watts (W): The product of volts and amperes in phase with each other
    2. volt-amps reactive (VAR): The product of volts and amperes 90 degrees out of phase
    3. volt-amperes (VA): The vector sum of watts and volt-amps reactive
    4. Power Factor (PF): W/VA = cos(θ)

    The power supplied by the generators to a load is measured in watts (W or multiples KW or MW).

    Reactive power is phase-shifted power, measured in volt-amps reactive (VAR, KVAR, or MVAR).

    VAR is caused by AC power flowing into an inductor (e.g. an electric motor) or a capacitor.

    The resultant in volt-amperes is the vector sum of the real and reactive power (VA, KVA, or MVA).

    In May 1996, I read Scientific Study of Unidentified Flying Objects again and noticed these facts:

    1. Relay Q29BD trip setting: 375 MW (megawatts) and 160 MVAR (megavolt-amps reactive).
    2. This means either the 375 MW or the 160 MVAR could trip the relay.
    3. The actual power on the line was: 356 MW and approximately 160 MVAR.
    4. The relay tripped out when the reactive power exceeded 160 MVAR!

      It was operating at the trip point!

    5. All it took was a small phase shift, not an overload, to trip the relay.

    Since the MVAR was right at the trip point, starting a single large motor would have tripped the relay.

    It tripped, then other relays on parallel lines tripped as more than 375 MW went through each one.

    Suddenly unloaded, generators went out of phase with each other, tripping them on high MVAR values.

    Correction capacitors on power lines cancel the inductive phase shifts from large motors (upper right).

    The same thing happened again in 2003.
     This time, a correction capacitor set (e.g. right) was ordered turned off by a public official for inspection.
     This happened when the official demanded it, regardless of the needs of the power system at the time.
     Without the corrector network, the system operated at the trip point and tripped out on high MVAR.

  75. My dream of God showing me how relativity really works in 1996
    relativity vectors

    Space-time has 4 dimensions and is flat.

    Everything travels at the speed of light. There is no other speed in the universe.

    The direction any frame of reference is traveling is Lorentz-contracted to zero length as observed in that frame.

    The direction any frame of reference is traveling at lightspeed in is the time dimension for that frame of reference.

    The other three orthogonal dimensions are seen in the frame of reference as space.

    Any observed velocity slower than lightspeed (including at rest) is a vector difference between two lightspeed vectors.

    Objects at rest relative to each other have parallel lightspeed vectors.

    An observed acceleration is actually a changing of the angle between the lightspeed vectors of objects.

    Part of matter's motion is particle rotation and revolution.

    Because of this, material objects travel linearly at slightly slower than lightspeed.

    This slowing distorts space-time, causing gravity.

    This also shows that faster-than-light speeds, antigravity, and backward time travel are impossible.

    I later developed trigonometric methods to calculate relativity, simplifying the work.


  76. The expansion speed of the universe is constant. We are observing cosine error.
    relativity cosine error

    Scientists are reporting that the speed of expansion is getting faster and faster, based on spectral emission lines.

    I was shown (above) that everything in the universe travels at the same speed - the speed of light.

    The apex at the right of the diagram shows the observers (us).

    The red lines show the paths of the galaxies from the big bang to their positions as they are visible today.

    All of these galaxies are traveling at the speed of light away from the point of the big bang.

    The blue lines are the actual paths of the light from being emitted by a galaxy to us.

    The violet lines show the line of sight we appear to have when looking at the galaxies along the blue lines.

    The more bent the path of the blue line from a galaxy to us, the more the spectra are redshifted.

    The orange line is used to calculate the angle between the emission of light and its being observed:

     - At the galaxy, the orange line is tangent to the blue line.

     - The angle between the orange line and the violet line is the angle of vision.

     - This angle determines the amount of redshift.

    The more the spectral lines are redshifted, the slower the universe appears to be expanding at that galaxy.

    The farther away (and older) a galaxy is, the slower it seems to be expanding.


  77. Passive attachment for 4-submaster mixers encodes surround sound.
    channel strip insert encoder
    panning in surround

    This encodes for any "Regular Matrix" surround sound, including:

      Dolby Surround,  QS,  Electro-voice,  and Dynaco.

    Part of a typical mixer channel strip with a sub 3/4 selector is shown.

    My encoder is inserted into the group (sub) inserts 3 and 4.

    Groups 1 and 3 are panned left. Groups 2 and 4 are panned right

     (Some mixers do this by default).

    Groups 1 and 2 bypass the encoder circuit, so they mix normally.

    Groups 3 and 4 pass through the encoder, so they mix in reverse phase.

    The sub 3/4 selector selects front (released) or back (depressed).

    To encode in the front of the surround image, select sub 1/2 (release).

    To encode in the back of the surround image, select sub 3/4 (depress).

    The channel strip pan pot positions the part in the left-right direction.

    Since each channel strip is set independently, all parts are encoded simultaneously.

    A Dolby Surround panning diagram is shown at right. Phase select is IN (1/2) or OUT (3/4).

    Note: Make sure that no front-encoded channel has any sounds also in any back-encoded channel.

    Monitor the mix through the appropriate decoder.


  78. The human mind activates certain functions at periods that are multiples of the brainwave period.
    human mind operations

    Brain cycle
     

    We were doing human reaction time trials in the motor control lab where I worked.

    The experiment had a subject push a start button, then push a stop button when a light turned on.

    I kept seeing that reaction times of multiple trials were spaced in groups at multiples of a value of about 1/4 second.

    I started looking for something in the computer causing a spaced interval in the timings of taking samples.

    After using a randomized timer and not observing such intervals, I concluded it was not in the computers.

    I then compared the intervals in different subjects. Each subject had a different period between the groups.

    The periods ranged from about .15 second (6.7 Hz) to about .40 seconds (2.5 Hz).

    This is about the range of brain wave frequencies in normal adult humans (simplified brain diagram shown).

    The timing of the start button, noticing the light, and pressing the stop button are synchronized to the brain waves.

    Each item is timed to the end of a cycle of the brain. This is what bunches up the reaction times.
     e.g. The light comes on. But the subject doesn't notice it until the end of the next brain cycle after visibility.
     Then the brain must issue the order to press the button, using one or more brain cycles.

    This can cause errors in such reaction-time dependent systems as using stopwatches and VASCAR.

    vascar speed finder

    VASCAR control panel
     

    VASCAR is the Visual Average Speed Computer And Recorder (used by police to measure highway speed).

    It must be assumed that the + or - error in VASCAR caused by this is -.40 second (the worst case).

    These are the worst case errors for the times between start and stop marks caused by officer reaction times.


  79. Why you hate your voice in a recording:
    bone conduction

    When I was doing sound, many of the performers complained that their voices sounded wrong in the recordings.

    I told them that the recordings sounded just like their live voices. They would not believe it.

    Most of them were demanding that I turn down the treble and increase the bass in their voices.
     - But if I did this, the entire recording sounded muddy.

    I asked if they knew why the old movies have actors with muffled voices. Most said it was the ancient sound systems.

     - The screen actors guild demanded what was the academy curve to cut treble and boost bass on all vocals.

     - The result was that we got union-enforced muddy-sounding movies for years.

    Then I played a tape of all of them singing together. I asked each one how each of the others sounded.

     - Each one said that all of the others sounded fine.

     - Then each one of them said his/her own voice sounded squeaky and weak in the recording.

    Then I played the tape again with the treble cut and the bass boosted.

     - Each one said that all of the others sounded muddy and dull.

     - Each one of them said his/her own voice sounded normal.

    Then each one wanted only his/her voice altered, but not the others.

     - I explained that I want a recording where other people hear the voices sounding normal.

     - "If your voice sounds normal to you, it sounds muffled to everyone else."

    The explanation is that people hear their own voices by bone conduction in the skull, not through the air.
     - The bone conduction emphasizes bass and reduces the treble you hear.
     - Only you hear your own voice by bone conduction. Every person hears only his/her own voice that way.
     - All other voices you hear are heard through the air. And everyone else hears your voice through the air.
     - So if we cut the treble and boost the bass on each voice, then everyone else hears their voices as being muffled.

    Vocalists must learn how they really sound in a recording and accept that it is a real reproduction of how they sound.


  80. Why you hate your driver's license photo:
    mirror image

    I did an experiment to show why people do not like their driver's license photos.

    I had a friend who hated to see pictures of herself. She said they were always ugly.

    I took a photo of her without her knowing I took it.

     - Then I printed the photo with my computer. I also mirror-reversed the photo and printed that.

     - I showed her the two prints. She picked up the mirror image print and said "Now that looks like me!"

    Then I explained that the print she liked was a mirror image of the other print.

    The explanation is that most people know what they look like from what they see in a mirror.
     - So the self-images most people have are mirror images of themselves.

    Try holding your driver's license in front of you and look at it (and yourself) in a mirror. It will look better to you.


  81. I told the City of Bloomington IN why the 10th and Woodlawn signal had the highest accident rate in town.
    yellow trap lead yellow trap faces flashing yellow arrow

    In 2005, the city reported that the intersection had the highest accident rate in the city.

    Most of these accidents occurred at night (when traffic is light).

    The signal had a single shared left turn face for westbound traffic on 10th (top is west on this diagram).

    The left turn was recalled every cycle because there was no turn lane.

    Woodlawn had an actuated phase, turning green only when traffic was waiting.

    A yellow-trap occurred on every cycle where Woodlawn did not get a green (in the diagram, the red arrow is a crash).

    Eastbound left traffic was unaware that when the eastbound signal was yellow, the westbound signal could still be green.

    DANGER: NEVER assume that oncoming traffic has the same color signal that you have.

    After I told them, they set the signal so the left turn arrow did not display unless traffic was present on Woodlawn.

    I found out about the flashing yellow arrow signal for preventing yellow trap in 2006.

    The city replaced the signal with one with flashing yellow arrows left turns in 2016 (lower signal diagram).

    Properly installed flashing yellow arrows prevent yellow trap for any sequence.

      This is true only if all approaches have flashing yellow arrow faces and they are correctly set up.


  82. The cochlea in the ear does a natural mechanical Fourier transform to discern pitch:
    ear diagram cochlea freqs
    ear function sound sorting

    The purpose of the cochlea is to sort frequencies and measure amplitudes at each frequency.

    The Fourier transform is commonly used to convert a time spectrum to a frequency spectrum.

    Every non-linear function can be represented as a sum of (infinite) sine waves like this:

    fourier function  Where: N = number of samples n = current sample

         k = frequency (Hz ... 0 Hz to N-1 Hz)

         Xn = amplitude at time n  Xk = amplitude at frequency k

         i = √(-1)

     

    This mechanical doohickey sorts frequencies by locations of resonant nodes on membrane R.

    The distance from oval window G to resonant peak N on membrane R finds the frequency.

    Sounds cause membrane R to bounce up and down at resonant points.

    The lower the frequency, the longer the distance between G and N is.

    High frequency nodes on membrane R are near the oval window G.

    Low frequency nodes on membrane R are near the helicotrema S.

    The atonal lowest frequency sounds vibrate the entire membrane R up and down.

    Infrasonic frequencies pass through the helicotrema gap S instead of making nodes.

    Consonant (good-sounding) sounds make gentle ripple patterns on membrane R.

    Dissonant (awful-sounding) sounds make violent ripple patterns on membrane R.

    Nerve sensors are placed all along membrane R.

    Each sensor responds to the resonant frequency of membrane R at the point where it is.

    The cochlea (J) is actually coiled up, as in the top two diagrams.

    The sound-sorting process is illustrated at right.

    Distance to the first peak in the waveform is used (marks on graph baseline - right).

    This peak finding is exactly what the formula above does.

    You have two of these mechanical Fourier-transform frequency sorters - one in each ear.

    Now you know how you can hear sounds up to 20 KHz using nerve cells that run at up to 20 Hz.


  83. How to drill a hole in a pingpong ball:
    mini lathe

    One of the scientists where I worked came to me with a hand drill, several boxes of pingpong balls, and
     some dented, smashed, deformed, and impaled pingpong balls.

    He told me "I need one circular hole this size (points at the drill) in each of these pingpong balls."

    After considering the problem, I chucked a center drill bit the same size in the tailstock quill of the shop lathe.

    Then I chucked a pingpong ball in the headstock spindle chuck, just tight enough to keep it from slipping.

    I spun the ball with the chuck at drilling speed counterclockwise as seen by the tailstock.

    Then I fed the tailstock quill to plunge the stationary center drill into the ball.

    Within half an hour, I had drilled all of his pingpong balls.

    This made a nice neat and accurate hole in each ball. The ball spun, not the drill bit.


  84. How to recognize bad science:
    bad sci

     

    bad sci

     

    bad sci

     

    moof

    I was assigned to find the many ways that bad science occurs.

    I found there are several ways bad science can happen:

    • The study has not been verified before being given to the press.
    • The investigators are trying to prove what they already believe to be true (see image).
    • The investigators do not know enough of the science or mathematics needed for the study.
    • Using predicted results of an effect to prove the existence of the effect.
    • Collecting the wrong data, collecting the wrong amount of data, or culling the data.
    • Collecting only a small amount of data to stay within budget.
    • Using a nonrandom sample when a random sample is required.
    • Using the wrong data type for the data collected.
    • Using the wrong statistical method for the kind of data collected.
    • Pressure is exerted by others to finish by a certain date, find a certain outcome, stay in a budget, or apply a certain bias.
    • The researcher is emotional about something or is afraid of a possible outcome.
    • Political pressure (including funding cuts) is applied to those doing the study.
    • Ignoring ceteris paribus rules (next item).
    • Some factor was omitted.
    • Results were faked to find a certain outcome.
    • Results were faked because an experiment was damaged and a student didn't want to have to repeat the class.
    • People disbelieved the result because it was not politically correct.

    Recognizing Bad Science shows the major sources of bad science.

    Examples of Bad Science gives real cases where bad science caused erroneous results.

    Hereditary Homosexuality has been the source of more of the bad science reported than any other subject.

    Too many "scientists" screamed "bad science" any time president Trump mentioned science.

      - They hated him so much that they refused to believe he was quoting real science.


  85. You can't follow Ceteris Paribus rules in a 10-year or longer study with computer data collection.
    no go byebye

    Ceteris Paribus means that everything except the item being studied must be exactly the same during the entire study.

    If the computer fails during the study, you can't buy an identical new replacement. They are all gone.

    If the computer needs replacing during the study, the operating system will be different on the new one.

    The IT department wants to upgrade all computers every 3 to 5 years. Ceteris Paribus means nothing to them.

    If the computer is replaced, the old data collection hardware will probably not work with the new one.

    The software you are using will probably not work on the new computer.

    If you buy identical computers and store one as a replacement, the parts in it will fail shortly after the original fails.

    So all of the time, money, work, and effort already in the study are wasted and you can't do anything about it.

    The IT industry does not care about anyone doing studies longer than 10 years. They want your money to upgrade.

    They don't care that science is destroyed by their selfish marketing decisions.


  86. I showed that work, not government, creates wealth.
    factory

    I was doing analysis of variance (ANOVA) on the various factors in the economy to find out which ones were related.

    When I compared economic growth to government spending, I got mixed results - some cases related, and some not.

    The factor that I found was most related to economic growth was work done to make useful products for the open market.

    Work is the engine that drives the economy.

    This explains why socialist plans never work. Socialism can't work because it discourages work.

    Notice how the people who want the "equality" of socialism want it because they think they won't have to work as much.


  87. The age-old mystery of how colored medieval stained glass windows provided white reading light.
    stained glass

    Accounts say that medieval churches with colored stained glass windows had white light inside to read by.

    Renaissance artisans attempted and failed to create such stained glass windows.

    It was accepted at the time that the art of how to do this was lost.

    I found it!

    I have been in several modern churches with this effect.

    People going to those churches don't know they have something special.

    There is no real secret to this. Modern color theory provides the answer:

    • The windows must have enough different colors to let in most wavelengths of light.
    • The colors must be balanced enough that they mix on white surfaces to produce visibly white light.
    • All of the colors must come from enough directions to prevent color shadows.
    • The glass must be translucent, not transparent.

    The translucent glass scatters the light from the window in many directions.

    The scattered light from all windows then lands on the reading material as white light.

    Transparent stained glass does not scatter the light, so the effect does not happen.


  88. I built a switchbox to select signals to decode any known quadraphonic matrix system.
    quad speakers quad switchbox

    The box selects outputs for 10 different speakers, each with its own amplifier.

    There are outputs for:

    • F - Front (placed as center front)
    • LM RM - Main (left and right front)
    • LW RW - Wing (left and right side)
    • LP RP - Posterior (left and right back)
    • B - Back (center back)
    • Z and N - Vertical (zenith and nadir)

    Selections are there for DS, RM, QS, EV, DQ, SQ, EU, UQ, BMX, H, HR, UHJ, and CS.

    Each selector switch provides an off position and positions for its speakers to play each matrix.

    Matrix coefficients are variable for LM, RM, LP, and RP channels using the blend controls.

  89. I had a very strong urge to go to the entrance foyer where I worked.
    heart flower

    There I met the love of my life. We had known each other before, but just casually.

    We chatted while she was waiting for her brother to pick her up.

    I started driving her home from work every day.

    13 months later, I asked her to marry me.

    7 months after that, she became my wife.

    I realized that if I had made any career choices different than those I made, I would never have met her.


  90. Binoculars projected Venus transiting the sun on June 5th, 2012
    venus transit

    My wife and I were working at a summer Bible school.

    I heard on the radio that Venus was transiting the sun.

    I got a pair of binoculars out of the car.

    I aimed the binoculars at the sun low in the west and focused the image from the eyepiece on the building side.

     DANGER: NEVER look at the sun through binoculars or a telescope. It will destroy your vision.

    Venus is the black dot near the bottom of the sun image. The image we saw was about an inch in diameter.

    As the children and teachers came out of the building, I showed them the image of Venus crossing the sun.


  91. I modified my car for winter driving in 2013
    second gear start

    My previous two cars had a way to lock out first gear for winter driving.

    I needed a car in a hurry and 'Cash for Clunkers' took away all of the cars with first-gear lockout.

    I made Second Gear Start for a 2002 Pontiac Bonneville to get this needed winter driving function.

    It locks out first gear in the automatic transmission to prevent wheel spin.

    A switch enables it. The white light tells me that the 2GS switch is on.

    The colored light tells me which speed the transmission selected:

      (dark = 1 red = 2 yellow = 3 green = 4)


  92. My practical switchboard for series and parallel circuits for four loads
    409 switchbox

    It can select any series combination of 2 to 4 120V loads.

    It can select any parallel combination of 1 to 4 120V loads.

    It can also produce several other combinations of series-parallel and parallel-series circuits.

    (Note that the order of components in series circuits is forced.)

  93. I finally got to see a total solar eclipse on August 21, 2017.
    total eclipse

    I had been waiting since 1963 to get a chance to see a total solar eclipse.

    This one was still at least 200 miles away. My wife and I decided to go.

    I built a solar projector with my small telescope, a tripod, white cardboard, and an easel.

     DANGER: NEVER look at the sun through binoculars or a telescope. It will destroy your vision.

    Fun Trying to See the 2017 Total Solar Eclipse

    The fun part was getting to and from the eclipse. What a mess!

    I took that photo during totality.

    And guess what. The next one in 2024 goes right over my house.


  94. A lamp that lets people with certain color vision defects see colors normally:
    color vision lamp

     

    color vision fan

     

    color vision color TV

    This works for protanomaly (red-weak), deutanomaly (green-weak), tritanomaly (blue-weak),
    and red-green indistinction.

    It does not work for protanopia (red blind), deutanopia (green blind), tritanopia (blue blind)
    cone blindness, or total color blindness.

    The lamp has colored LED bulbs in red, green, and blue - the primary colors of light.

    Be sure to get real colored LEDs, not white LEDs behind plastic color filters.

    These provide light with gaps in the spectrum in the yellow and cyan part of the spectrum.

    The defective retinal pigments are confused by light in the yellow and cyan parts of the spectrum.

    All other light sources must be turned off for this to work.

    Ordinary white lights can be provided for times the special vision light is not needed.

    Separate switches can be provided for each color.

    I also put this special lamp into a ceiling fan.

    A tricolor TV set also provides the correct colors on the screen and for room light (using a white raster).

    A tricolor computer monitor showing a white screen works too.

    En-Chroma makes glasses with sharp-cutoff filters that remove yellow and cyan light that work anywhere.


  95. This switchboard can select all possible device permutations in series and parallel:
    I5 switchbox

    It can connect any possible permutation of the devices in any series, parallel, or combo of series and parallel.

    The permutations include the polarities of the devices.

    It is expandable for any number of devices.
     For n devices, the circuit needs:

    1. Connection points for each device (normally two - outlet at top of each column in picture)

      - Only one device outlet is needed. Duplex outlets are shown because of their much lower cost.

      - For screw base lightbulbs, the connections are marked:
       C for the center terminal
       S for the screw shell

      - The C goes to the short outlet slot, and the S goes to the long slot.

      - Portable lamps are sold with polarized plugs with this standard.

    2. One column of switches for each device connection point (normally two columns per device)
    3. At least n-1 rows of switches for interconnection buses
    4. at least two rows of switches for power connections

    A power switch for the entire box can be added.

    This switchboard is not polarity-safe and is not neutral-safe (see below).


  96. Proof: neutral-safe, polarity-safe switchboards can't do all series/parallel permutations.
    safe proof

    NEUTRAL-SAFE: If the neutral connection to a lamp is opened, the hot connection must be disconnected too.

    POLARITY-SAFE: A lamp screw shell must be kept at a voltage closer to neutral than the center terminal voltage.

    The circuit shown is a possible switch position of a switchboard that proves this fact.

    The switches on the board in the item above are set to make this proof circuit.

    Notice that the conditions for polarity and neutral are met in the top version of the circuit.

    The only difference between the first version and second version is that bulbs were traded between the sockets.

    The switches are still in the same positions for both diagrams.

    Notice that, in the bottom version, lamp 3 has the closer-to-neutral voltage on its other terminal.

    This means that no switchboard for all series/parallel combinations can prevent a polarity or neutral error.

    I wasted years trying to design a switchboard for all series/parallel combinations with no polarity or neutral error.

    Any switchboard circuit that provides bridge circuits such as this cannot be either polarity-safe or neutral-safe.

    A switchboard that is polarity-safe and neutral-safe can be made, but it cannot do all series/parallel combinations.

    Sensors that notice polarity and neutral errors could be used to shut down the switchboard if they happen.


  97. I realized that noticing the races of people is a built-in function of the human mind.
    races

    I was trying to train my mind to not notice race. I found I could not do it.

    The part of my mind that recognizes people puts out interruptions when people of other races are seen

    I was unable to stop these interruptions. They are a built-in part of the recognizer hardware.

    The original evolutionary purpose of this was a warning of interacting with some other specie. It misfires with race.

    What I did was redirect those interruptions to see good things instead of bad things.

  100. My sayings that show the truths of everything:
    scroll

    The Principal Principle: Government should be last, not first.

    Life is a dirty trick.*

    Without work, this stupid planet cannot sustain any human population.

    Without profit, a company has absolutely no reason to hire.

    Actions speak louder, but politicians won't shut up.

    Ancient utopias ran on slave labor. That's why no utopias exist today.

    The only source of wealth is work.*

    You do NOT have the right to freedom from being bothered, offended, or annoyed.

    If you got a house for free, someone else lost a lot of money.

    When you perfect a foolproof device, they perfect better fools.

    You can't fight against God and win.

    A CD player is as useless without CDs as the CDs are useless without a player.

    Every time you want to observe a rare astronomical event, it will be cloudy.

    With n mousetraps, the (n+1)-th mouse gets all of the cheese.

    When Democrats have no argument, they use pejoratives, innuendo, prevarications, obfuscation, and namecalling.

    Wage and price controls never have the intended effect.

    Side effects of regulations to help the poor always hurt the poor.

    Raising the minimum wage inflates the money instead of helping the poor.

    The purchase price of a product MUST pay for all labor, materials, utilities, and taxes paid to make it.

    To raise the standard of living of the poor, cut taxes - raise the standard deduction.

    Those who want to defund the police want to commit crimes without being caught.

    Those successfully cheating at elections destroy the opposition ballots. This leaves no evidence.

    They can't recount the ballots the cheaters totally destroyed. The voters who cast them lost their votes.

    Democrats believe that they should never have to lose an election. Isn't that cheating?

    Republicans promise things that can actually be done. The winners win by promising the impossible.

    Republicans believe in and obey sexual morality. That's why there are more Democrats.

    Democrats try to solve every problem by being N-I-C-E. It never works. It always makes a mess.

    The science just tells us what can happen. But only belief systems tell us ways to do something about it.

    The only known totally fair election system is not used in any elections. Does this mean the officials want to cheat?

    Aren't taxes just legalized theft?

    High taxation makes the products shoddier.

    Businesses pay no taxes at all. They pass them on to consumers in higher prices and lower wages.

    "Palestine" was the Latin word for "Philistia" (there is no "f" or "ph" sound in Latin). So Palestinians are Philistines.

    Socialism does not work because it discourages people from wanting to do work.
      This is proved by the worker shortage caused by the extended and supplemental pandemic unemployment payments.

    The default afterlife destination is hades.*

    Atheists want there to be no afterlife. They will get hades instead.

    They can't design a record changer that plays odd sizes, randomly intermixes sizes, repeats any record, plays a single record, and doesn't touch the grooves.

    satan is a Democrat because he wants what Democrats want.

    The highly salaried artisans of the past have been replaced by technology (e.g. portrait artist replaced by the camera).

    Most of the trouble in this world is caused by people trying to get something for nothing.

     * Without God.
