I really like this new power supply. Everything has been work fine on it, except I still can't figure out the OVP. The over current protections seems to work fine. I have been going through the Make Electronics book, and I'm on chapter 7. Got tired of alligator clipping everything together, and started breadboarding the projects. That was pretty easy till I got to the relay stuff. Figuring out what contacts need to be isolated with the by the center channel on the board takes some getting use to, especially since I had to figure out the layout from clips to breadboard myself, but got it working on the second try!
