Though I will say: thanks, because your post motivated me to decide I will study electronics a bit more this winter.
The hardware is simple, the software is comparatively complex for me. In fact, if you don't mind physically moving the batteries to a charger, all you need as far as hardware goes is 3 NPN transistors and 4 resistors. If you can figure out how to write a program to read and write the control lines of a serial port (somewhat complex), it would be very easy to write a program to automate the measurements.

The very easiest to build is to take an analog clock and add a load resistor.
If America manages to eliminate obesity, we would save as much fuel as if every American were to stop driving for three days every year. To be slender like Tiffany Yep is to be a real hypermiler...

Allie Moore and I have a combined carbon footprint much smaller than that of one average American...
