Soviet digital clock analysis and restoration 

yes, we were finally able to all become enslaved to material things thanks to fall of sovite union, it feels great

I could never decide what was worse, the electronic buzz/beep or the old metal bells that were loud as hell.

@@user-ww2lc1yo9c Now, im not saying America is to blame for the fall of the soviet union, but thats EXACTLY what im saying and the people behind it should be charged with crimes against humanity.

I agree, and also, shout out to our Brazil!

@@rjltrevisan Promoting world peace from the UK. Been to Sao Paulo, Rio, Salvador an Porto Allegro, what a fantastic country and the majority of Brazilian people are, in my experience, friendly and welcoming. Really miss the coffee, beef with black beans and rice.

@@isoguy. Nice!

@Рыбаков Андрей Фигня. Я знаю бабу которая выбросила пылесос из за того что в нем пылесборник забился. 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. Как в старом, бородатом анекдоте, про пепельницу в машине. Не ожидал что в реальности такое встречу.

автопереводчик не понимает "радиоконструктор" считает конструктор здесь это инженер, а не лего

У нас такой дисплей 30 лет отработал. Пока я его не разбил. Только часы были в трехпрограммном приёмнике. Сейчас он работает, несколько лет назад дисплей перепаял))

Могу подогнать новый дисплей

Собирал и такие наборы, как вы, и собирал на ИЕ 18, 13, ИД3, или ИД2 в случае со светодиодами. Приятные воспоминания. Заметили, у автора и осциллограф советский?

wow!

From memory, even Windows had this feature. Most clock radios I have seen in hotels too.

Such systems. wow!

In the eastern block there was a very limited range of products which were produced for many years so getting parts is not so hard.

Long vid, enjoyed it so much it seemed to be over in 5 minutes

I know I am late, but just in case someone reads this and wonders the same thing - all these VFD displays are still available as NOS (New Old Stock), typically from Ukraine. I recently bought pack of 6 for something like 70 EUR including shipping.

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! 😃

@@Willam_J Good to know! I've always preferred 24 hr, not sure why though lol. I have no background in using it. Saves the whole "is it AM or PM?" confusion when you wake up in a stupor I guess

@@Willam_J I had the same idea, until I almost broke one clock, which had that shitty PCB & diffusor sandwich. Of course, the LEDs weren't equipped - well better check the first digit as you said :D

And this clock would probably last for decades. My family had bunch of similar ones, last one that we stopped using somewhere in 2010, and it was completely functional, just not needed anymore. So yeah, you pay 1/3 of average monthly netto salary back then, but that's a "long time investment" :)

@@MacIn173 Yes, this clock work very long, but on the other hand you can also buy simple mechanical alarmclock for 3-5 rubels, and it’s work at least 10 years without problem, or some “quartz” alarm clock (with clock dial, without fancy electronic digits) for 10-12 rubels (my grandma use this for years). So 45 rubels for digital alarmclock in the middle of 1980s - it’s for wealthy electronics geek of that time. :)

Kinda like cars or homes, the money was not the biggest issue, there was a 10-14 year waiting list in the case of cars, similar for houses, some jobs had the perk you could buy the house or car straight away, you chosed a job based on the perks more than the salary. Often the perk was what you could take home (hidden) and trade on the black market, or favors you could do.

@@Fridelain "there was a 10-14 year waiting list in the case of cars, similar for houses" that's not true. Average queue span for an apartment was 5 years (that's statistics, not biased subjective opinion). For cars, even less.

Soviet are the same as above, but usually as copies of 15-25 years old western tech. And build quality was worse.

​@@KrotowXbut no shit, that's why the Amys are spying on the Russians because they want to copy the technology ... Russia was and will develop independently 😘

Thanks :) but it sometimes makes the videos bloody long :D

@@DiodeGoneWild It's alright, longish ones like this are fine to just bookmark and then put on a 2nd monitor. Watched it all the way. Better than shorting mains voltage for entertainment. ;)

There's no need to shit on ElectroBOOM to praise a different creator. The channels are for very different audiences ranging from very amateur hobbyists with an interest in electronics and literal schoolchildren to professionals in the field. If you don't fit into the first category, it is only natural for you to find ElectroBOOM's content unentertaining.

Modern things are more overcomplicated :). You just don't see the complexity, it's hidden inside a chip that contains billion transistors or even in its software.

@@DiodeGoneWild and trillions of nand gates..

The design is based on poor integration capabilities in Soviet IC fabrication. It is quite simple.

Doesn't just need to be replaced, it needs a damn good slapping first.

😀

lol

😂

^^

I think avoiding problems with inrush current is what slow blow fuses are for, ain't they?

@@plainedgedsaw1694 Just after posting my above comment I remembered about T-type fuses, so yup you are right. My initial mindset was to leave every component as original as possible

I've seen one of those still working at one of our local hospitals.😊

@Moraceae And also the country when if you entered grocery shop, there were near nothing to buy :-)

74141 and their soviet equivalent K155ID1 are quite common. I have like 500 of them if you needed...

@@DiodeGoneWild haha, now that's a stock! LOL I wonder if I find some in the stuff I'm getting from the mentioned friend. He's downscaling his lab, giving away most of the retro stuff to me, in return for some help with cleaning up the place and providing a loving home for the tubes, radios etc. Lots of nixies there! To think that my lab got so much cool stuff this year, and there's probably gonna be a lot more.

@@DiodeGoneWild wow do you have a warehouse or something like that? i often see you with a ton of vintage stuff . How do you even keep track of it? not to mention find it. (Also how does one engineer get 500+ as in extras) ?

Seems like you already know the answer.

@@ursulmusic I know of at least several.

Which countries do not these days? Not many probably.

you can insert any country and you will probably be correct .

VFD's are still used in Western and Far Eastern consumer electronics. I roughly estimate the average household has on average 2 to 3 modern electron tubes: 1 magnetron and 1 or 2 VFD's.

Fortunately vacuum fluorescent displays are still being made for new products, such as the displays on Hi-Fi equipment.

And BigClive immediately before that.

lol .. I thought immediately of both of them .. SHOTS FIRED!

He may be one of the famous ones, but I'm sure there are many doing these foolish things. (E.g. see the early KREOSAN videos.)

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...

He's not poking fun: he's telling what he likes. I also don't like watching someone shocking himself and swearing every minute, so I don't watch that guy's channel even if he's quite clever. Even Dany does extreme things sometimes (e.g. angle grinder tricks), but he doesn't overdo it for my taste.

It's more like greenish in reality. The camera recieves it wrong.

some people call VFDs green, but I call them cyan or turquoise or simply "VFD color" :D. But the green plexiglass turns it into cold green.

He is actually fluent, just has a thick accent

In eastern block it was impossible to use mains frequency, because it was never right.

@@xsc1000 Was it due to trying to balance the load with output? Or was it just not that precise from the plant?

@@sammorris2721 Yes it was the way how to balance the load. In the peak frequency dropped, in the rest frequency returned to nominal 50Hz. So in average it was always lower than nominal.

@@xsc1000 so phase issues then. That sucks. Especially for time keeping...

@@sammorris2721 In fact till mid 80s there were still a shortage of installed power. And they prefered heavy industry over standard citizens, so there were even switch offs when power were needed by industry.
