Hey Bruce Micro1700 good laboratory going on over there.
I’m glad the question of changing voltage came up, because that’s a branch of electronics I’ve always meant to explore.
I have (in deep-storage) a Ramko Audio Board whose power supply is (from memory) a 12-Volt DC bus that feeds a string of little black devices, each of which changes from 12-V to particular other voltages, like 6-Volts, 24-Volts, and I think up to four or five total different voltage busses. Maybe later I’ll dig out the schematic.
My guess is that someone will know what those little voltage changers are called.
