Fermentation Chamber

Had a request for some details on my fermentation chamber.

It’s a pretty simple plywood box on a stand and casters, lined with styrofoam insulation board.

I modified the cheapest, smallest window ac unit I could find to move the bulb thermostat from inside the unit, to outside underneath the AC.  Since our nights can be cool here, I also put the bulb inside a tin can with a 7w nightlight to make sure that when the external controller tells it to turn on, it will turn on.

Currently using an stc-1000 temp controller to control both the AC unit and a small heater.  Oddly enough, over the spring, both of those have come on at some point or other.  If the beer gets too cool, fermentation can slow down or stop, so it’s important to maintain an even temp.

Currently, I’m working on adding a Pinoccio based fermentation controller that will allow me to put the data and control of the unit up on the web.
