Circuit specialists stocks a variety of regulated linear benchtop power supplies with adjustable current limiting at remarkably low prices. The lt3081 guarantees 0a output current as long as the ilim resistor is reduced below 200ω. Adapt an old computer power supply to use on your workbench.
Every diy makers need this kind of bench power supply for making another project.
If you use an 18 to 20vrms transformer with 2a current ratings, you can have output voltage v out1 from 1.2v up to around 16.5v available at con3, and v out2 from 0v to 15v available at con2. This one has 4 outputs. Voltage output controlled by a potentiometer; Schematic diagram sw3 is the on/off switch.
