Beer Fermentation Temperature Controller

As a homebrewer the idea of a controlled fermentation isn’t new to me, there are many products out there that do this type of thing. The problem with most of the products, in my opinion, is their sometimes insane price tag or lack of features. So i set out to make a DIY version that satisfies most of my needs with materials I already had. This prototypes isn’t by any means perfect and will definitely improve in the future.”
