I thought there was a way to put a bridge rectifier (or something REAL
close) on a DC power supply that would let you plug it into a DC load
and the polarity wouldn't matter.

That and a lab power supply with voltage and amp meters would pretty well
remove all possiblity of damage to board. (Well, most of the porbablity
anyway)
