I'm working on a Son of Fermentation Chiller project, and I'm looking for an appropriate thermostat. I'm looking for something that the thermistor could be removed from the unit, so I can mount it on the outside. The goal is to be able to do something very similar to this project here. Unfortunately the thermostat in the preceding link seems to have been discontinued. If anybody has any ideas, that would be a huge help.
Edit: I have 12V DC fan, and power adapter, I'm very comfortable soldering, but setting up a relay, if necessary, is a bit beyond my expertise.
