Im Aussie so its 240V but if you use a different power level you should still have the same problem.
How can i take a 240V source and convert it to 12V or 5V without noise.
By noise i mean is the hum of a transformer.
Its only small but when you expect places to be quiet and there is a hum in the background it makes it hard to go to sleep.
Anyone have any ideas?
Mosfets or BJT's seem like the way to go, basic chopper circuit. Then a few caps to smooth the voltage.
