Power Usage and Generation Display

This is a dial which displays the electrical consumption and solar generation in my home in real time.

This takes data from our eGauge energy meter (http://www.egauge.net/) to get the current power being used in the home and the current power being generated by our solar panels, then uses an Arduino and a pair of servos to move the hands to indicate the current power levels. If you don't happen to make this, you can also view the output of our eGauge at http://egauge14368.egaug.es

This project was inspired by the fact that having the eGauge has made my whole family more aware of how much electricity we use, and much more careful about turning things off to save energy. But the usual output of the eGauge is entirely web-based, so I would have to turn on a computer or iPad to view our power usage. This gives us a way to see what the electrical usage and generation is at all times without having to turn on a screen.
