Leonardo has been working with nitinol and needed a decent variable powersupply to give a controlled current to nitinol wire to heat it precisely. Not finding one at hand he took matters into his own hands and has built a variable dc voltage source with voltage and current meters (and multiple fixed voltage outputs) based on a standard pc psu.

Outputs are +12V@10A,+5V@12A,3.3V18A,-12V@0.8A,-5V@0.8A, and one variable 0-10.5V using an lm338 5A adjustable 3 terminal regulator running off a 12V line.
