The arduino power monitor needed a little field-expedient power supply modification.

Running the arduino and network interface from 12V to the arduino board was causing the arduino regulator to get way too hot (the current was around 220 mA. I kluged in an lm317 regulator to drop the arduino power to 7V, and disspate the extra heat into the case.
