Peltier Fermentation Chamber for Beer

Most homebrewers know the importance of controlling the fermentation of their beer. I initially used fridges, but fridges only cool the beer down. What if you need a chamber that can both heat and cool? Enter the peltier! Peltier modules get hot on one side and cold on the other when voltage is applied to them. If you reverse the polarity of the voltage, the hot and cold sides on the peltier are switched. Peltiers are the heart of this project.”
