This is great! When I was much younger and back in the day, (way back) I used to troubleshoot CRT's, stereos, radios, etc., then moved to PC's especially the old 286 CPU, MS DOS machines. The most fun I used to have was repairing many of the "suite case" PC's (Compac's). I never got tired of watching what I repaired start up and run. I remember my old soldering lessons and always got a kick out of LEDs, even made gadgets with blinking Leds inside of a composite plastic case, stuck an antenna on it as a fake security device. Moved on to listening circuits (9-volt battery powered), got into antenna tech, etc. Electronics are a great hobby.
Was taught 60 years ago to make sure a joint is mechanical bound before soldering. This person makes his method look easy. My old hands are no longer steady enough to attempt such soldering. Still have my 100/140 Watt Weller soldering gun and two pencil soldering irons.
I still have my 100/200 watt Weller soldering iron! Old tube radios and TVs, had to had own with enough watts to solder on the steel frame! Pencils where replaced every 6 months!
Почитал отзывы, дело не в супер мультивибраторе !!! Дело в том, что человек сделал красивую поделку, все показал, и теперь начинающий радиолюбитель сможет это с легкостью повторить !!! Спасибо, молодец !!!
Другой вопрос, зачем? Ну спаял, посмотрел 2 минуты и забросил в дальний ящик или разобрал? Вот я для своей собаки ещё примерно в 1991 делал мигалку на ошейник, чтобы в темноте её было видно, на совковых аккумулятора и далеко не супер-ярких светодиодах. Использовал КР1006ВИ1. А сейчас мигалки уже с современными яркими светодиодами доступны для покупки.
oh man ... I miss the days when I would spend hours troubleshooting and repairing. I still find myself opening up discarded electronics and collecting components. I know its a sickness. Love this I will be looking for more

It's a good way to learn about electronics by watching these small builds, though it's a little more helpful with narration of what and why they're doing things...
The "high street" company where I used to do this - about 200m from where I now live - went bust 6 or 7 years ago. Not enough custom or customers. Sad.
I went to Radio Shack, back when it was all about these parts and a free flashlight or free battery each month ... LM3909 is the unforgettable integrated circuit I adored
Check out Micro Center. They only have 26 locations in the US, but if you live near one you may want to stop in. The one near me made Radio Shack look like...a shack.
Sorry, but to produce a multivibrator its not necessary to use two optocouplers. 2x NPN-Transistors, also the LEDs u used and some resistors with 2x Caps do the same job. And the unit Caps do use is not H (Henry) but F (Farad, µF)... But perfect bendings and also soldering is really good. You use a really good soldering tin.
Причём, можно было задавать частоту, при помощи подстроечных резисторов! Правда нагрузкой служили лампочки накаливания на 3,5в., а для звуковых мультивибраторах - наушники или ГДШ-0,1, (тут меняли параметры кондёров и резаков). Хм.., - на таком звуковом, сделал на базе "датчика дождя" из журнала "ЮТ" (Юный Техник), - для новорождённой дочки, (в 90-м) - "Датчик смены пелёнок" ! 😆 А, при помощи сборного переговорного устройства из магазина "Сделай Сам" - слышала вся семья, когда присупать к процедуре..! (И опрелостей не было, впрочем, как "радио-нянь" - (они потом появились) и памперсов...)😆😅🤣 Также, слышали, когда дочка просыпалась и плакала. (Жили в частном доме и территория с летней кухней, беседкой). Желаю мира всем!
В итоге получился обычный мультивибратор, как реле поворотников автомобиля. Но зачем-то слишком переусложнëнный. Намного проще сделать то же самое на двух абсолютно любых транзисторах. Там и паять меньше - три ноги вместо четырёх. И деталей меньше - всего два резистора, два транзистора и два таких же конденсатора. Светодиоды - в цепь коллекторов.
As a retired Electro-Mechanical Engineer ( H N D ) we never went down as far as components more the heavy stuff, three phase etc. So after watching "You've Never Seen This Before, Great Idea PC817" I have now subcribed. 👍👍👍 Keep up the good work.😎☝
It's not a multivibrator. It is two independent, unrelated oscillators. As far as I understand, the generation is due to charging and discharging of the capacitor. The potential on the emitter of the transistor changes, and this opens and closes the transistor, despite the fact that the optocoupler LED is constantly emitting. BRAVO ! Это не мультивибратор. Это два независимых, никак не связанных между собой генератора. Насколько я понимаю, генерация происходит за счёт заряда и разряда конденсатора. Меняется потенциал на эмиттере транзистора, и это открывает и закрывает транзистор, не смотря на то, что светодиод оптопары постоянно излучает. БРАВО !
Stil got it!!! as soon as I saw you were making a pump circuit I knew what it was going to do!!! Awesome movie set flashy light console thing! Christmas lights, attention getters on a sign, etc.
F'me, the most interesting aspect is that the frequency of each 'half' is slightly different, meaning the pairs of double-LEDs will slowly go in and out of phase... 😊
I enjoyed watching this (at the normal viewing speed) remarkable demonstration on how to solder LEDs in sequence to obtain a strobing light effect. And besides there is a lot of soldering and the correct diods and what have to put in place. I am no electrician, so i need all the help to achieve what you have demonstrated in this. I am sure there are people like me interested in how you achieveed this.

Thank you for showing us your interesting circuit. On a different note, I believe you are using flux in this production. Could you tell me the flux you are using? I'm curious as to what kind of flux to use to achieve such beautiful soldering. I'm sorry if it's difficult to read because I changed it from Japanese to English using Google Translate.
Look for a flux for electronics applications. One brand is Kester. It comes as a paste in a small can or as a liquid. Get the paste. Note: do not use an acid flux; it will corrode.
@@PinePondCTDevilsHopyard-fy3hj Extremely hard to get lead solder these-decades. RoHS (Restriction of Hazardous Substances) Regulations killed it in the early 2000s. Since Brexit, Britain has had the OPTION to revoke these laws ... but lead remains very toxic, and even if we did revoke the laws, nobody would dare to face the liability issues of using it. Electrical solder is a range of tin-bismuth-cadmium alloys these days. None of which are nice chemicals, but none are as bad as lead.

The 12VDC supply was unnecessary for a drive voltage, tell tale by the green LEDs illuminating in a yellow-to-red color spread., symbolizing that they were being overdriven to their breakdown voltage and would eventually fail due to said breakdown if not dying to thermal breakdown instead. Something along the lines of 6 to 9 VDC would've sufficed. I've blown up enough LEDs due to voltage overdrive to know that the colors changing to something they weren't made to be is the sign that they are dying and quickly.
'tis nearly 40 years since I enjoyed mucking about with these things... and for me, it was to put a flashing light on a boomerang so I could do a time lapse photo at night to analyse the flight... Maybe an NE556 dual timer would've done it simpler with a smaller parts count? ... but it would likely be more $$$.... YMMV...

Soldering was not great either.
It's not a multivibrator.
It is two independent, unrelated oscillators.
