RGB dimmer teardown and schematic (no microcontroller)

This must be the first time I've ever referred to the humble 555 as a microcontroller. To be fair, it does have 8 pins and runs at 5V. Maybe a few less transistors though. Huge processing-power errors aside, this is an interesting and different use of the 555 from normal. It doesn't use the main output pin, but instead uses the standard configuration to provide a triangular waveform directly from the capacitor. This is a very retro circuit, but it works well and is fully serviceable at every level, with scope for customisation in terms of PWM frequency and potentiometer range. The search keywords to find these on eBay are - rgb knob dimmer If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-   / bigclive   (extra streams and channel interaction) Or alternatively:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
