- 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.

The buzzing sound brings back memories of waking up in a cold morning with a horrible sound and having to go to school. Thanks for reminding me that my life is so much better now! :D
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.
41 minutes worth of watching, even though I'm from Brazil and never saw any clock barely as similar to these here, it's still highly entertaining to watch it and learn the physics behind such interesting vintage devices. Also, you got such a massive spare components for them, so they seem like a very common household appliance there.
I agree, and also, shout out to our Brazil!

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!

@@pu5epx That makes you one cool dude in my books.
Man, your clock videos are very entertaining and educational. I love to see old-time technology that still works. Thank you very much for this video.
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.
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.
Спасибо!
В конце 80х собрал часы на основе советского радиоконструктора с микросхемой К145ИК1901.
Работали исправно больше 20 лет.
А заменили их только из-за полной потери яркости такого же индикатора как в этом видео.
@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?
I have a dozen old clock radios in my lab, always fun when you find a quality one with interesting analog circuitry to analyze. Thanks again.
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
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!
wow!
From memory, even Windows had this feature. Most clock radios I have seen in hotels too.
Such systems. wow!
One thing that really sets you apart DGW, is your thoroughness. You leave no stone unturned or text overlooked. It's an admirable quality.
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. ;)
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".
There was no single minute too much in this video ! Videos of DiodeGoneWild are so educating and relaxing at the same time!
Carlsons lab, Shangoo66 , and Diode gone wild are the three best electronic channels on CZcams.No bullshits only main points which is understood by showing highly practical videos .and no shit edits..
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.
My mom was a bookkeeper in 1982 and her salary was 5 rubles a day. But although this clock would seem like expensive , almost a half month salary, food (very few options available) was cheap and there was not much to buy so this clock was accessible to common folk to spend there savings on.
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.
A very enjoyable video. Fascinating to see the evolving circuit design over time. Thanks for the video, as for the length I did not notice it, the time just flew by - a good indication of how the video is engaging.
Excellent video! You have an impressive collection of Soviet VFD clocks and I guarantee that some viewers got excited when you showed your box of displays ;). 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.
As someone said before "There are three types of clocks: analog, digital and soviet"
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 for this very interesting video- great to see an in depth analysis of the Soviet IC's as well as the clock repair. I enjoy all your videos and the format of them is perfect.
Loved the video, especially the diversions and distractions! Nice to have a long one, fascinating stuff these old displays.
I think you reviewing soviet stuff has become one of my favorite topics of videos from your channel. Amazing!
I like your explanation videos. Between you and BigClive, you've pretty much taught me everything I know about electronics - so much that I drew a schematic from scratch today to explain the difference between a switchmode flyback power supply and one of the old AC transformer supplies (to help explain why capacitors used to have to be quite big!).
Happy to support your channel. Screw the algorithm, I want cool quality content and your channel has been one of the best. Thank you!
мужик да ты крут! коробка индикаторов осциллограф советский.... :)
I really enjoy your longer videos. Very relaxing and informative!
This brings memory, i have built one like this myself when i was a kid. I wish i still have it ;)
I like the longer videos. You do a very good job at explaining things and some explanations require more time.
Wow…for some reason i find old soviet electronic devices really interesting and fascinating…
Would love one of these clocks, here in italy nixie tubes/displays are really unusual , especially considering that we adopted lcd displays in the early 80s, transictioning to them directly from analog clocks.
17:51 "a certain country also needs it's main control chip replaced" priceless!
Doesn't just need to be replaced, it needs a damn good slapping first.
😀
lol
😂
^^
I think this channel is exactly what EEs (as myself) look for. After seeing a flood of clueless "engineers" "teaching" electronics on CZcams, your rant about transistors vs. optocouplers (@ 22:46) and the "disclaimer" at the end of this video made me very happy (actually, Patreon-grade happy ;)). Thank you very, very much for sharing all of this!!!
Im sure everyone in eastern europe had one of these, so did we! Was working beautifully and brightly for many years until it dropped and died. Great clocks.
It didn't feel very long at all. Absolutely fascinating!
Please keep making these vids man, your teaching method is awesome
Keep the long videos coming DGW, enormously entertaining. It's always good to see the old, ridiculously overcomplicated, Soviet era electronics
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.
Excellent videos, I really enjoy the old 60s/70s electronics from the Soviet Union. Remembers me when I still had time to tinker with vintage electronics for fun. Keep up the good work :)
You often blow my mind with something in your videos. Now it was the box full of displays. 😲
Thankyou for the long and deep video!
I have assembled similar when I was 15 as DIY from kit. Sweet memories
I love how it does so much with so few ics.
That mesr meter is almost as important as the continuity function on your meter when trying to fix something.
Very nice video. I like clocks. I have no problem with this longer video. I'd like to see more of your clocks.
Thank you! I have learned some new stuff from your in depth video!
Keep on going...
41 minutes love it, old reliable tech.
I agreed to the cat :D ...but still I made it to the very end, too. Thank you for the deep insight of the idea behind this clock.
I like this long video. I like to learn how things work.
I also liked the crazy funny free energy videos and things like that, I don't know if that channel still exists. It is better than "accidentally" shorting mains voltage every video.
Loved this detailed video!
TOP content. Quality beats quantity. I highly appreciate this approach. Danyk, great work, as usual. Keep this philosophy of high quality, low "wow factor" videos. I do not need artificial drama or hype, this is much more valuable. Thank you.
Super educational and interesting journey into this piece of vintage home electronics. Thank you! Two things to note: bigger caps will lower the ripple very little but they will cause higher inrush current when you plug it in and so you might change the fuse constantly, also lower rated fuse will cause you the same issues, so leave them like they are...
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 think we all agree we love when you diverge a little from the main subject as we learn a lot xD
Thank you for a fascinating video.
I watch always hole videos from start to finish. Elektronika clocks are cool and on my buy list for sure.
I really enjoyed. I love vintage soviet electronics. Very Cool!
That was awesome, we still have these at parents home.
Great video! Incredible this was made in the 90s! Just shows you how far behind they were in Soviet times. Looks like something made in the 60s with bakelite.
@Moraceae And also the country when if you entered grocery shop, there were near nothing to buy :-)
It has a bad internal connection. You tried to burn through the corrosion & establish a new connection. Too bad it died :-(
They are amazing pieces of Technology.
Thank you for explaining everything to us, showing us how you fixed it & such a long video.
I enjoyed it very much!👍
Very interesting. Thanks for posting
Nice vid! Amazing clock as well. Brings back a nice feeling to see theese old displays. I remember them as a kidd how a starred at them when I was in bed at night. I just loved the colour and find it peacefull in some way. I actually like your longer videos going in depht with things. Take care my friend. Allways love your videos.
Really nice video. And of course the comments about some country needing a replacement control chip and about tractors are priceless.
Excellent video! Thank you!
Really enjoyed the longer video you had more time to explain things clearly.
Actually preferred the long video rather than the rushed ones.
Thanks for taking the time to make such interesting and fun content.
🇺🇦🇬🇧
Very common clock from my childhood. We had these in form of large wall clocks in corridors and waiting halls. Basically the same circuit, but larger indicators.
FYI: Common Soviet aluminium foil electrolytic capacitors often had very bad quality even for new ones.
I've seen one of those still working at one of our local hospitals.😊
I like looking at these soviet electronics, it is so weird and different from what I was used back in the '80. It's like being on a different planet, discovering the use of orange transistors, strange value resistors and odd part numbers with Cyrillic letters; a completely different world and hard to imagine it is not another planet but just an iron curtain that separated the world.
Thank you for the video. It is fine that it is long. Such devices are interesting
22:47 the optocoupler comment deserves a special thumbs up 👍
Nice video as usual.
The 9V battery is shorted on the old schematic, okay on the new. The latter is so much more logical and better at explaining the device's principle of operation.
Thanks for the episode. One of my friends gave me an identical or very similar VFD tube and the video will be helpful in getting the thing up and running.
I'd say "please don't be the guy who uses transistors just because he doesn't know how to use driver ICs" if the 74141 weren't gone. Tough choice now.
You got a hot damn lot of cool stuff there. I also do, having had electronics labs for roughly 20 years. If not for space and finance constraints, I'd keep and get a lot more :)
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) ?
Mate your accent is difficult to understand but some very good information, I couldn't understand the Russian data sheet so I'm glad you explained it. I can't believe you had new parts on hand. It was really interesting.Good job
Kitty pawing the carpet means Kitty is Happy, so thats good to see :)
Its 2022 and now i finally know, that it is possible rejuvenate vacuum florescent display :D
Old is gold
Thank you
Thank you for very interesting video!
Thank you for your support ;)
Very interesting video! 😁
Great Video. Very interesting thanks.
Awesome, thanks for sharing!!!
Very Cool Alarm Clocks Great Video :-)
These clock look very cool with that blueish light :)
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.
17:50 Sneaky ;)
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.
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.
Can’t wait to have time to watch this
Soviet equipment is fascinating stuff and looks like he has cornered the market of these alarm clock fluorescent displays !
Great stuff !!...cheers.
Amazing, big thanks.
Super! Thank you very much!
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...
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.
great video!
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 CZcamsr has their own accent and all are interesting.
He is actually fluent, just has a thick accent
Nice pile of spares, too!
Sunday, cat, soviet device & electronics = instant thumb up
У 86 році купував такий конструктор та сам паяв. Гарний був годинник 😊
WOW! The price being carved into the plastic really shows the stupidity of command economies.
What an eye-opener!
That's a military type fuse holder. And yes it is silver plated.
What a nice video!
I watched this until the very end, thank you for the long video!
Funny to hear you talk about certain larger channels, but not fair to poke fun at them.
Your content is different, much more technical but not crazy like MarcoReps!
So, we watch you for the high quality content. And for your cat, of course.
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 crazy that you have a full box of exactly the same displays. Very good. Excellent video as always. Cheers.
Hee, nice man! Good explained.
Great video. like you said it was long but the quality was great as allays and i think for stuff like this keeping it in 1 vid is better then splitting it in 2 20 min vids since it make is easier to track
Nice video.
I absolutely love that cat, he/she has the cutest face..☺️
And, enjoy your accent.
Contented subscriber.!
That was so cool to Watch. Its really interesting taking a look into old Technology. It looks so good! No invisibile unreplaceable SMD components, just transformers, THT colorful components... You're getting my point :)
I have this clock in a DIY version (sold as a set of parts with assembly manual and without case and cables)
Как у тебя язык не устал только) Видео класс 👍 сразу видно что специалист.
i love this types of clocks
Got one of these, blue, with 4 tubes. Actually, all I did to it was cleaning. My model got a front glass, it's possible to turn it around, so the scratches are on the inside. Capacitor was in perfect condition, checked it.
I enjoyed the literal pronunciation of the english words with your accent..!
Screw becomes skree-ewe.
Torn between the content and the accent.
Good fun video.
