Fermentation Control System
Originally uploaded by mikeysklar
This week I've been assembling electronics for an ice chest hack that will hold a specific temperature for a prolonged period. Its use will be fermentation, which usually requires a hold of 60F-90F for a duratino of a few hours to several weeks. The control system I created allows the user to set a desired temperature and follow the progress via a LCD or on-line via pachube for data logging purposes. Holding the actual temperature will be done with a peltier unit because it can both cool and heat for which I will build the H-bridge circuit. Today you can see the schematic and breadboard. Feedback is welcome.
