Computer Power
Should I use a computer power supply to make a variable voltage supply for general electronic purposes?
I was considering splicing the 12VDC output of an old computer power supply unit into a voltage divider circuit with a pot as one of the dividers in order to control the output voltage. Is this feasible?
This is not the best way because it only works with small loads.
Much better to use a voltage regulator. The circuit is simple with only a small number of components. Generally if you go to a store that sells electronic components (Radio Shack - US, Maplins - UK) someone there will draw the circuit and sell you the bits for small cost.
