The Linux Duracell CPU load monitor is a program that drives a Duracell or Energizer on-battery tester to display the CPU load of a system.

It can be easily adapted to display other things that can use a slow bar graph kind of display that varies between 0% and 100%.

Instructions to hack a AA-battery tester and turn it into a computer display are included in the distribution.

Requirements:
An AA Duracell battery with a tester. Energizer testers should work too, but I haven't tried. I got a pack of Duracell Ultra M3 batteries, product code LR6-MN1500.
1 x 3V power cube
1 x 2 KOhm resistor
1 x 4.7 KOhm resistor
1 x 10 KOhm resistor
1 x 4N25 or CNY17 optocoupler
1 x BC547A or 2N2222A transistor
1 x TIP41C transistor
2 x 1N4004 diode
3 x ON/OFF switche
1 x female DB9 connector
1 x breadboard (get it somewhat large if you build the simple display)
1 x clear plexiglas CD case
1 x Socket-7 heatsink (if you want to build the more precise display)
4 x 10x3mm wood screws (if you want to build the more precise display)
