Got to looking at different bench power supplies and using an LM317 seems the easiest method but only 1 Amp unless you follow the data sheet design.
A simple pot on the adjustment pin is really all that is needed but lets enhance the power supply with a pic and an LCD.
This schematic is my first draft and maybe needs adjustments here and there.
AND yes 4 amps as per data sheet page 17
Reason for this is I purchased two of the tiny power supply modules off of Ebay and one won't change the voltage. Stuck on 10v.
Just need an LM317 to bread board circuit.
Thinking of using all 1/2w resistors??
