Salvaging a computer power supply to power your uBITx

R N Harp needed a regulated power supply to run his µBitx and a couple of arduino kits, but he didnt feel like shelling out hard cash for a $100+ power supply unit.

Instead, he modified an ATX power supply from a dead PC.   He gets 3v, 5v, and 12 volts.   Additional parts were already on hand.   He also salvaged a bunch of other parts from the dead pc, including a few toroids from another power supply.
