hack a pc power supply so it can be used as lab power supply
- stable output of 3.3v - 5v - 12v
- isolated from earth ( eg connect 12v of one psu to gnd of another to build 0 - 12 -24 v)
- daisychain 220v cable
- start switch (connects green + black cable so PSU starts up)
- status led (on -off)
- startup sync jack in-out (daisychain) sync several psu to startup at same time (separate optocoupler)
- needs a 10 Ohm / 10W resistor (-- paspas will confirm this) on the 12V line to ensure stable voltages (apparently the psu needs some load to work decently)
