Hey readers! I've just finished my first real electronics projects (sort of). I finished it but it doesn't work. I will upload schematics but you can't finish it without the blue PCB in the picture. You can get it on eBay from the seller alice1101983. I'll try to get the schematics up soon but it's really straightforward, inputs on one end of the board at the modulated power supply on the other. I just added a switch to turn on or off the power led.
