Update: Power supply

Alright so if you made this power supply you probably noticed that it wasn't powering your LED's or motors or whatever. Well the problem is in the last post I said to solder your negative wire to the middle terminal on your potentiometer. You do have to do that but instead of soldering your test wires to the third terminal they actually go to the same one as the negative wire. So move the wires you have on your third terminal to your second terminal and you are good to go.
