I'm designing a project which involves a microcontroller sending data over SPI to two SN74HC595N shift registers which, then control some level shifters to turn on and off some 12v end devices. (The MC and the register circuit are on two separate boards) I want to power the shift registers and...
Hello, -:)

Therefore, I thought about winding my own transformer (first coil 3-4 turns, second 800+).
Before I go for that folly, I wanted to ask whether there might not be...
