It's a Sanguino board, rev 1.3a
I also thought about running the ground through the board and the + to the bed, actually tried just connecting the bed directly to one power supply, but something about the way the load is handled makes either power supply auto-shutoff when attached directly, but not when run through the board. It's weird.
I suppose it's time I go out and get a heavy-duty power supply. Just wanted to know if I could save some cash by being cheap and using what I've already got sitting around.
