Finished the build for the Fermenter over the weekend. Here’s a video going over the physical components for the project:
The chamber itself is based on the Son of a Fermentation Chiller. with the only modification being that I made mine a bit smaller than their plans.
The django based web app is all open-source. The code & instructions for building it are available on GitHub. https://github.com/mfwarren/Fermenter
The Pi will run a django based web interface that will provide simple and minimal control and logs of the brewing process.
The electronics are fairly simple, and as soon as I figure out how to generate a circuit diagram I’ll add instructions for how to solder together the prototype board.
