Excellent! I taught for two years... I know what you mean.
I can't imagine the control logic is that difficult. Maybe it's tough to have constant current and/or constant voltage control? I don't think the system would be dynamic enough to need fancy PID control... (like the current limiting suggested for your controller) I have a 12V power supply that I can hook up to a 6V battery to charge it and manually adjust to the desired current, so it seems like a computer could do it without missing a beat.
