Most minimalist circuitry yet (Patreon)

Another scarily minimal fan control module - with schematic

I've featured a bigger version of this in a previous video. But this is probably the most minimal version other than adding a very simple on/off remote control module. I meant to say 18W apparent power for the module's low power factor. Not an issue until the power companies start charging for it (and they will). The module is designed for three speed fans where the fan motor has a capacitor and tapped winding that allows three different speeds based on which of the taps is powered. It also has an output for a fan swivel motor. The design is impressive for the very basic power supply running a microcontroller. Companies like Padauk specifically tell you to avoid using their microcontrollers with capacitive droppers for reliability reasons. It can result in a very noisy and spiky power rail due to coupling of mains borne electrical noise. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
