Most of the inspiration for this project came from Adafruits excellent guides and my desire for a temperature controlled fan to cool my flat. I didn't want the fan to come on when it was hotter outside, and as the fan cooled the air, I didn't want it on unless it was 2 degrees colder outside than it was inside.
I have recently added a webcam to the setup so that I can actually see what the weather is like outside without having to get out of my bed. More on that Webcam and FTP upload here.
