but wow that digital meter is sexy 😍 I have a lightbulb-shaped color-changing desktop lamp that had a circuit a lot like this. After maybe 15? years of near-constant use, the blues stopped working, then overall the whole thing started malfunctioning. Kinda broke my heart for a bit. Then the tinkerer in me decided to take it out, retrofitted a candelabra bulb socket in it, and run a similar-functioning little color-changing Christmas lightbulb in it. Happiness restored 😊 I love that stupid thing 🤣💡🌈
What I like about those older colour changing lights with the separate IC is they have fairly even brightness and proper colours through the colour cycle. I have a few old garden solar lights that still had the separate IC with a 4-pin RGB LED and these cycled red, green, blue, yellow, cyan, purple and white. The slow colour changing LEDs where the LED itself contains the IC are terribly imbalanced with the green dominating, at least with a variety I bought from AliExpress, Amazon, etc. i.e. red, intense green, blue, bright olive, cyan, purple and a pale greenish cyan and there's no way to tame the green with higher ohm resistors without the blue getting too dim.
That blue thingie is called a lightning arrestor I blocks electric spikes...that's odd to see a milar cap fail they do crack from heat but I've never seen one fail in that low of current..
I myself are big into LED’s. And I’ve wondered this regarding LED’s powered from AC line voltage. Obviously, one needs a resistor to drop the voltage down from 110/220V to ~3V. But what about when the diode is blocking the all the full reverse voltage. Wouldn’t the full 110/220 voltage cause a breakdown as the reverse bias voltage is rather low?
The capacitor drops most of the mains voltage. The bridge rectifier and 100µF Cap make it to a pretty good DC. The Zener here sets the max voltage to about 18 Volts. The LED's are in series. 5 blue Leds is around 15 Volts. 5 green Leds' about 11 V, 5 red Led's about 9 Volts.
@@RODALCO2007 Thanks. I've bought LED pilot lights made in China that simply had a forward dropping resistor and LED. Works, but since when reversed biased - the reverse breakdown voltage is exceeded, and the LED's don't last long.
@@RODALCO2007 hum never heard of that model must be a good one has the big reels I'm looking for..you should do a video on the reel to reels u have I see u had 2 there..
Will do, usually don't bother anymore because of copyright claims on music tracks. but I can upload music from RU-vid library of course.@@anthonycoach4551
