Here's an easy to build desk power supply with quick connect plugs.
Really efficient for any electronic test when you need 3.3v / 5v / 12v / 1.7v / 7v / 8.7v (the tensions you get with a classic computer power supply, between the different colored wires)
It requires a little DIY:
I used a 0.5mm thick galvanized steel to make the electrodes (and weld it to the wires of
the Computer power supply)
and 4 small springs to make the button pushing up (to press any wire you put in it, against the metal plate)
I use it soooo often, I hope it will help youre prejects going faster ;-)
