    I had this exact clock on my bedside as a kid! I was constantly hitting the "snooze" button on the top, so I actually hardwired a toggle switch in the back to disable that button. On school days, I would leave it disabled, but would enable it for weekends. 😀

      I have this exact clock sitting next to the computer I'm watching this on now! lol Bought it at a thrift store years ago for maybe $10. It's been plugged in pretty much constantly and it works perfect, including the backlight

    Neon lamp in the COPAL sitting in front of me has been going for 350,000 hours. She's been flipping longer than I've been alive with periodic motor lubrication.

    I had this GE clock at one time with the flipover panels, but the version that I had used a more normal font for the numbers instead of the LED-look alike font. It was really interesting decades ago when I opened mine up to see how they did the wheels. The curiosity started because I had noticed when I looked at the clock in the dark, while it was changing, I could see numbers through the gap between the tiles and I wondered why (remember, I was in my larval years at the time.. but it was an interesting discovery at the time to see how it works. This video brings back a bunch of memories).

  • @lindacangelosi3245

    At about the same time as that GE radio that you’re working on, I had a Philco-Ford R-788 clock radio. I also thought that it has a digital display, but the numbers were more stylized and when they changed, they sort of melted into the next digit. It was wild. Only after the backlight bulbs failed and I took it apart did I realize that it was just a mechanical clock with an amazing display. I still kick myself for not keeping it. While there are a few pictures of the radio online, none of them mention or show the display. If you could find one I bet it would make for a great video.

    LED design drawn by someone who never saw one! 😀
    Amazing to remember the world where doing all that mechanical design and manufacture was cheaper than just using real 7-segment displays. For a very short time, red LED displays were a sign of modern high tech. Now, of course, it's more of a nostalgic throwback.

      They should have done a Nixie Tube look version 🙂
      Regarding digital clocks, in 1977 my Christmas present was the Maplin Digital clock kit. More exciting than a Pong Game. About a year later I persuaded my Mother to buy a kit which proudly proclaimed "Now you can have a Microprocessor in your house.". The kit was for the Chromachine 24 tune door bell using a mask programmed TMS1000.

    The serrations on the top of the light pipe looks like a fresnel lens cross section to avoid hot spots in the resulting illumination.

    • @FranLab
      @FranLab  Před 8 měsíci +3

      Honestly it does not work for that, there is a good hot spot - but in other flip clocks there are multiple lamps above and behind the numbers, and this is likely a feature for that kind of illumination.

    • @teardowndan5364
      @teardowndan5364 Před 8 měsíci +4

      Not necessarily fresnel, just odd angles to help with diffusion. Yes, definitely there to help with hot spot mitigation.

    • @ScottRise
      @ScottRise Před 8 měsíci

      This was kind of my thought. Not necessarily like a Fresnel, though, as the edges would reflect the light instead of refracting it. The light coming out the sides of the neon lamp would reflect off of each edge and down onto the numbers, spreading some of the light that would be wasted onto the outside numbers.

  • @Mrdibzahab
    @Mrdibzahab Před 8 měsíci +10

    I have a clock with this mechanism (but different style numbers). I find it much more pleasing to watch the time change than with a flipclock. You can change the exact timing between the gears to make it even more pleasing to watch.

  • @hiram1923
    @hiram1923 Před 8 měsíci +4

    I suspect those dividers in the numbers are there because they simply spray-painted them using stencils. That's also why you have that paint bleeding. Of course for some numbers you wouldn't need dividers in the stencil, but they just put them in all of them to give it a uniform look.

    I have a similar GE clock on my entertainment center...a couple years newer. Neon dial light. I got it in '77 or '78. It's been running non stop ( non counting moves and power failures) since then.
    The neon light still works.
    Years ago, I had a mechanical digital clock radio with a small argon bulb dial light ...the numbers painted with fluorescent paint.
    I have several ac clocks from the '70s...those telechron motors seem to last forever...

    My grandmother gave me a very similar model in 1972 or 73. Same numbers, alarm rotating motor indicator. But an illuminator bar to see the numbers in the dark. The bar dimly illuminated 2 grain in turn dimly illuminating the tiles. Illumination was variable. A friend had the exact same clock. Their numbers would light up even when room lights were turned on. My clock numbers barely showed in very blackened room.
    Around 1978 i gave the clock back to my grandmother. She needed a bedside clock. By that time, the humming motor was too noisy for me. But my grandmother was almost deaf.
    The clock lasted to the mid 80s. On clock autopsy, the motor bearings wore too large and the gear teeth could not remain engaged. One grain of wheat bulb was burned out and both were misaligned with the light pipe. I do not remember if there was or was not a reflector. But i remember the surprise and disappointment how significantly more light reached the tiles when the one good bulb was properly aligned. I was disappointed i never got to see the display with both bulbs properly aligned.

    A nice design, arguably better than the conventional flip digit clocks that seem to suffer lots of mechanical failure.

    Wow now that’s pretty interesting clever forward thinking stuff from the 70’s,instead of using a seven sigmented display or a led display,they just use wheel gear system wich is a cheaper but not less effective alternative to also get people with a lower budget access to a clock.
    This is just simply amezing😁👍

    The lil sawtooth bits in there are to reflect the light better, so it spreads more evenly, looks better.

  • @DanielleWhite
    @DanielleWhite Před 8 měsíci +3

    I had a different version of this. Mine was a clock radio and the digits were unbroken lines rather than faux 7 segment style. Mine lacked the running wheel on the right of the time display. The mechanical alarm eventually wore out at 7 from having been set to that for years; what set for 7 it would go off at 7:10 instead. The alarm control was a slider switch on the top of the cabinet which had four positions for Off, On, Alarm and Radio, one of which was to use the radio as the alarm rather than a buzzer and the position indicated by four oval holes adjacent through which an orange painted part of the slider would show.

    foil HVAC tape works good for reflective.. I repaired a radio diual lightr that had a small incandescant bulb in it as each end.. they used the same tape (GE singapore also).. I cut all the old tape out and used the HVAC tape to encase the new bulb... never an issue.. I had this clkock as a kid and you could see it in the dark... the neon bulb gave off a soft warm light.. perfect to sleep to

  • @InssiAjaton
    @InssiAjaton Před 8 měsíci

    My bedside alarm clock is something i built of a kit way back when. You might not have ever met an IC that was built in P-channel technology, like this one. I did not know of that, and was thinking something was wrong with it, when the transformer output was something like 35 V after rectification. The display is built with 7-segment LED blocks, except the 1-second flashing is made of two individual LEDs. They are mounted between the hour and 10-minute LED blocks. I disobeyed the instruction to leave them high. The result was a sturdier structure, but the second blinking is not visible except from straight front. The plastic clamp lock housing was after several years drying out and twisting, popping open. My fix was (and still is) transparent packing tape. But only after I had beefed up the main bus filter capacitors for a longer hold time during any power glich. I then realized the likely benefit of the hig supply voltage, as the clock works down to below 10 V power. Moreover, the clock chip apparently has constant current outputs for the multiplexed segments, as the brightness does not change with changing bus voltage. It has also a crystal time base, which was originally trimmed a little too fast. When I adjusted its trimming capacitor (already before the packing tape fix), the time count since then lags a little, wich is more to my liking - it is easier to bump the minute forward - two or three times per year - than to roll it all the way around. In any case, it works beautifully still after the years, or actually decades! The packing tape is also holding so perfectly, that I have not wanted to cut it open, although now I would have a GPS synchronizable frequency counter to adjust the crystal frequency much closer to the nominal value.

  • @lorensims4846
    @lorensims4846 Před 8 měsíci +4

    I had a clock very similar to this in '75 except it used flip cards for the standard, roughly Helvetica, white numbers on a black background.
    But I never saw anything like this fake LED display.
    Only that plastic overlay they had in the stores to suggest what the display would look like once it was actually plugged in that you pulled off as soon as you got it.
    A real puzzle!
    I think the slightly blurry print of the red digits may have been meant to suggest a glow.

  • @RonaldJS
    @RonaldJS Před 8 měsíci +2

    I had a ‘digital’ knockoff clock in the early seventies. It had three wheels with flat faces and numerals on the facet. It would click on the single digit turning, clank on the double digit and clunk on the hour digits. You could look at the clock as you went to bed and wake up in the night wondering what time it was, you just think about it for a second or so and your brain would say to you 3:47 or whatever, and Holy Crap it would be right. Somehow your brain was keeping track of the clicks, clacks and clunks!

  • @MrPage62

  • @MrDuncl
    @MrDuncl Před 8 měsíci

    In a 1980s oven I had there was a 24 hour digital drum clock. The interesting bit was that the 0 to 23 was done using two interleaved drums. The left hand drum displayed something like blank-gap, 1-gap, 2 gap, 21, 22, 23 so it could change from 23:59 back to 0:00 with minimum rotation of the drums. I made the mistake of taking the top of because the motor was getting noisy and spent hours getting it back together because if everything wasn't perfectly aligned it would do things like get to 19:59 then jam.

    The Gottlieb pinball machine company did the same thing in 1978 when they were a little slower than the other pinball companies in switching over from electromechanical to solid state. Before they did, they made a few electromechanical machines with black score reels that had simulated red LED digits printed on them.

    @coondogtheman Před 8 měsíci

    I had an old alarm clock that was similar to this one but without the digital segmented numbers. I found it in a barn and it did work it was prone to stopping and it made me late for school a bunch of times even if I set it ahead a few hours. Wasn't the Mr. Fix it back then like I am now but it probably just needed some oil. Ended up getting a real digital clock a cheap sony dream machine clock which I still have the guts and bottom of it and it still plays FM radio. No AM because it's missing the ferrite core antenna. Was late a few times because the snooze button would stick down and stop the alarm.

    @ramosel Před 8 měsíci +2

    It wasn't this particular clock, but something very similar when I went off to school in 78... The digits were day-glow as well but the small illumination bulb was UV. So it was unnoticeable in day time, but was quite vivid at night... without illuminating the room. I wonder if this was the reason for the paint selection on yours but they opted to keep costs down and only use neon.

    @emilyadams3228 Před 8 měsíci

    It's strange that the motor date code would be 1975, but the label wouldn't have a zip code. Zip codes were phased in from roughly 1963-65, so a handy rule of thumb in the wild is that anything without one is from before 1965. Maybe GE figured it didn't matter, cos they didn't expect anyone to write to them.

      @@FranLab you’re right, indeed I saw at the end of the video that the display is barely illuminated. It could be that the intention was a kind of Fresnel but certainly it went bad 😂. However it is a fascinating mechanical stuff.

    Not a flip clock as we know them, I'd call it a rotating drum type display? yeah, that sounds good!

    It's not a flip clock but a cyclometer clock. But the rotating tiles are very interesting and unusual. If the tiles wouldn't be able to rotate the clock would have to be twice as big.

    This "stair shaped" upper area of the bezel looks like a Fresnel lens to me. Probably it was added to spread the light more evenly, in some way.

    Split-personality clock in more than one sense... 😂 Nice! 😀👍

    I think the cerated lamp diffuser uses the flat sides as reflectors, like a prism would do.
