If I burn down the house, SWMBO wont let me brew...

Ok, I played around with the wiring and thermostat, and here is what happened:

This is the thermistor in the thermostat, I just desoldered the joints and pulled it out

I wired some 24 guage wire into where the thermistor was

and attached the thermistor on the other end of the wires. I had to play around with it a bit to get the polarity right so the thermostat would work, but other than this, and having very little soldering experience, this wasn't too bad

For the power supply, I attached some more wire to the terminals in the thermostat where the batteries go

and attached these to the orange 3.3V output and black ground on the computer power supply that I used jas0420's lazy mans modification on

yay for learning something new and not burning the place down! Next step, a second thermostat and the fans.
