Soviet digital clock analysis and restoration

Ғылым және технология

Repairing and examining a soviet digital alarm clock Elektronika (Электроника) 6.15 from 1982 with a vacuum fluorescent display (VFD) IVL1-7/5 (ИВЛ1-7/5). The schematic and how does it work. Old version with K176IE12 (К176ИЕ12), K176IE13 (К176ИЕ13), K176ID2 (К176ИД2) and two K161KN1 (К161КН1) chips. Comparing it to the newer version with K176IE18 (К176ИЕ18), K176IE13 (К176ИЕ13) and K176ID3 (К176ИД3). Attempted VFD display regeneration. Possible modification for nixie tubes using K561TM3 (К561ТМ3) and K155ID1 (К155ИД1) chips instead of K176ID3. Correction: K561TM3 contains 4 latches, not 6.

Попросила зайти глянуть почему пылесос не тянет, я на 5 минут заглянул к ней, в шутку ляпнул " выбрасывай у этого пылесборник забит".Через несколько дней зашел в гости а она реально его выбросила и новый купила.

    First, I was like “Where could he possibly find a replacement display?” Then, I was like “Where the heck did he get all of those replacement displays? In all of the years that I’ve serviced Vacuum Fluorescent Displays (VFD’s), I never new that I could rejuvenate the display, by over-voltaging the heater/cathode, which would increase the cathode emission. I’ve been an EE for 33 years and I’m still learning new things. I love it! 😃 Don’t ever worry about the length of your videos. When the content is this good, time has no meaning.

    1:05 - "K" (Коррекция) is a correction button used to synchronise clock with the radio broadcasted signals of sharp time. The radio broadcasted several short beeps following the long beep on which a user pressed this button and the clock automatically adjusted minutes to "00" and hours to closest value, e.g. 13:57 would be adjusted to 14:00 but 14:03 would be adjusted to 14:00!

    I don’t know if this would interest you, but this is a cool idea to try: If the display has an entire digit in the leftmost position, you might be able to turn it into a 24 Hr clock. (Some clocks only have a ‘I’ in that position, instead of an ‘8’.) If your display is the right type, open it up and try to find a datasheet for the clock IC. Read the datasheet and see if one of the clock IC pins let’s you select 12 or 24 hour. (Most do.) The selection is made by either pulling the pin high, or low. (Applying positive voltage (high), or attaching it to the power supply negative (low). This makes the clocks useful if you’re in the military, if you’re a ham radio operator, or if you listen to shortwave radio. I’m sure that there are other applications, and you may have some unique ideas of your own. Heck, you might want to do it, simply just to do it. 👍 I hope that this was useful. Take care! 😃

    Thanks for the video! These electronic clocks were developed on microchips with a low degree of integration in the 1970s. Also, an electronic clock on the VFD was also made on the microcontroller kr145ik1901 (kr145ik1911)(кр145ик1901 (кр145ик1911)). This series (k / kr145 ****) is very old (the beginning of production - the end of the 60s - the beginning of the 70s) and was used in many places. As well as a more advanced version of an electronic clock with a VFD display with a memory of alarm clocks for the week kr1005vi1, which was installed in the VCR "Электроника вм-12".

The fact that you go into depth is the reason I watch and support you, so definitely keep doing your own thing. In my opinion, this is the best electronics channel on youtube. I also love that you show us equipment that I might not have ever seen before and will never encounter in my country. This is probably one reason that Nixies are so popular, as Westerners did not grow up with them and thus find them novel and fascinating ;). I enjoyed seeing your Czecho-Slovak Nixie clock as well and love how it's displayed in a transparent case.

    Cool that these displays were still being made in 1999! I always find it interesting which products survived past the Soviet era and which did not. As these clocks were apparently ubiquitous where you are, I could imagine someone trying to make a modern version as a retro product for those that still remember them, but obviously the displays might be impractical to manufacture. As with Nixie and vacuum tubes, you need specialty machines and the expertise to use them and much of that has already been lost. I really like that people are reviving the art of Nixie production, but their products are ridiculously expensive :(. Things that were once cheap-as-dirt, embarrassingly antiquated commodities made by people considered peasants are now boutique luxuries made by people considered artisans.

    Nice to see that you got the clock back into good working order! Seems like it needed a display and a capacitor... I wouldn't mind one of these old clocks either, they're probably much more reliable than the modern ones, and will last for a lot longer than anything modern. Most modern components and electronic items are designed to be throwaway, they stop working after a certain time and that's it. The only thing I would do if I had an old clock like this, or a nixie clock, is to try and create a better power source for it, as I'm not keen on having something permanently plugged in all the time to mains in case it fails.

    This was fascinating, thank you. The way that the ckock functionality is split between the first two chips is unusual, and I guess was determined by the level of integration that was possible with their silicon manufacturing at that time. I also note the potentially lethal fuse holder. Depending on which pin on the mains plug is live, there can be mains voltage at the back of the socket or on the metal ring near the front. In the latter case, if you are touching the metal part of the fuse holder and the tip of the fuse touches the metal ring then you may get a nasty shock. Such fuse holders were common in the UK the 70s but I think the rules changed in the mid 1980s so this type of fuse holder could no longer be used. Cylindrical fuse holders still exist but the connections to the fuse are much better protected.

    I agree, I remember giving myself a nasty shock, when repairing the fuses of my fathers Pioneer amplifier from the 70ties. I had it running again and tried to stuff a second, seemingly unused fuse holder (it would have been for the 110 Volt part, but we use 220 V anyways as I found out later) with another spare fuse. It took months for me to touch the holders free of fear again, even when the main was disconnected. But I never failed to disconnect the main again before working on any electrical device...

    Well done for making such an informative and thorough presentation. I want to analyse the multiplexing and chip sets of late 1960s / early 1970s calculators and this has helped a great deal. Your pronunciation of English is certainly unique but your use of English language is perfect. I suspect you are reading from text, possibly a very good translation, but using the stresses and emphasis of your own native language. But don't worry - every KZreadr has their own accent and all are interesting.

    Some corrections: 1) alarm buzzer is generated by ИЕ12 (1 Hz on-off) and by autogenerator based on buzzer itself (it has 3 pins) and transistor. ИЕ12 is just a set of stobe generators. 2) you cannot replace the crystal on modern one without changing resistors and capacitors around it. Yea, inside the ИЕ12 it is typical invertor, but soviet crystals were different from western ones.
