  1. I am currently gathering the parts to make the Variable DC Power Supply project. I want to include a volt meter and a current meter. I understand how to connect the ammeter but as I understand it the meter will not read anything until a load is applied to the power supply. This could spell trouble if the pot is set for 2 amps and the circut can only tolerate 1 for example. So is there a way to tell what the pot is set for without connecting a project to the supply? Some additional circuitry maybe? Or should I just settle for turning the current pot all the way down, hook the project up, and bring the current back up?
