You've Never Seen This Before, Great Idea PC817

[@JD-kg3mx]

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.

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.

[@53-herbie39]

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.

[@russuoctavian8568]

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.

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.

[@MoppedGhost]

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 !

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.

[@PinePondCTDevilsHopyard-fy3hj]

Probably lead solder with Flux core.

[@clarencegreen3071]

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.

[@a.karley4672]

@@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.
