I will need soon to design a programmable load to test the 2.5v 60A power supply I have built for my little electrolysis project, and I was wondering if you freaks had any opinions as to what is considered best practice in this case. I do not need something very complicated, merely something to simulate a resistive load with a draw I can control from an AVR linearly from mA to 60A peak.
Is it easier/cheaper to buy an expensive instrument if I will use it very seldomly? Can I make it simple enough that it will not cost me more than about 100$ to build, counting board in for about 10$?
