Last night I finished my woodworking course at Sydney Community College (old Leichardt High School). My project was to make a box that will keep my beer fermenter cool, as our house gets to very high temperatures on sunny days.
It's a big box on quite tall legs, which a sliding out removable front panel and lift-out top. The design allows me to bottle the beer without moving the fermenter, which keeps the yeast from getting in the bottle.
I'm planning to line the inside with expanding spray foam. Cooling will be provided by a Peltier effect thermo-electric cooler controlled by this kit. Since I'm already cooling, I figure I can experiment with proper lager fermenting temperatures over the winter too!
