Heater control

This project has been a long time coming.  A looooooong time.  In fact, it was one of the first I started after joining Foulab.  The project is a set of wireless (well X10, so it goes through the house wiring) controllers for the heaters in my apartment.  Each controller uses a DS1820 temperature sensor, and an ATmega 168 microcontroller.

Heres one of the finished products, and a graph of the temperature in the kitchen.  The full writeup is on the Foulab website.
