Even though it is not quite finished, I used my power supply for the first time today (the first time for a real project, not just testing the supply itself). I was powering on an H-Bridge circuit for the first time, and wanted to a) ensure that it didn't suck too much current if there was a bug, b) see how much current was being drawn. It performed both tasks flawlessly (and for the record, there was in fact a problem with the H-Bridge board, so current limiting came in handy!
