How appropriate...keep me up to date on the fermentation fridge. I am in the process (still gathering supplies) of building an arduino-controlled corny kegerator. Re-purposed chest freezer, temperature controlled with the arduino and LCD readout for temps and beer names (and possibly amount left in keg). Brewing our pale ale this weekend along with a pumpkin ale. Anyway, off-topic, I will post back when I get a chance to try the matrix fully. Thanks!
