thought this might come in handy for someone on the board.
I run a UA5 (9v-12v) and a MicroCraper (5v USB) and didn't want to drop more money on yet another battery.
so..
I took my PR2E battery and hacked its cable. I wired up a seperate cable to it (spliting it off to two leads from the battery). One lead has a radio shack 7805 Voltage regulator inline. its dropping the 11v out of the PR2E down to 4.9v-ish. Powers up the MT just fine though. I'll be testing it to make sure it is not the cause of random shutoffs and whatnot. I had the battery to begin with, but the VR piece was a buck fifty. I hope it all works.
Yes, I'll be putting a fuse inline to the MT.
