Power Supply Active Load Tester – Open Source Open Hardware project

I’m working on a new weekend project that will be released as soon as I finish the Windows application and it will be released as open-source open-hardware project. The uber-cryptic title stands for “Power-supply Active Load tester”.
Recently I was in need for a simple device that will draw reasonably precise amount of current from my power supply unit under test and read the voltage and current draw. There are a lot of schematics and products that do just that, or you can do this just with two digital multimeters, op-amp, mosfet and potentiometer and that will probably work just fine, but I wanted to create my own version and try to improve it. 🙂
