Converting a old PC psu

Most decent workbench power supplies cost quite a lot, at least for a student. Whereas I have and old computer PSU lying around, so I figured I’d have a bit of fun converting it.

Taking inspiration from various other projects including the DIY Bench Supply from TG’s builds and the RepRap PCPowerSupply I’ve ordered a MIC2941AWT from Micrel, this is a 1.2A Low-Dropout Voltage Regulator that I’ll be using to supply a variable voltage. In addition to the variable supply I’ll be including terminals for the voltages supplied directly from the old psu.
