Attention all techies and homebrewers: I’ve got something for you. I don’t know a ton about homebrewing personally. I just recently brewed my first batch, and I hit a few bumps in the road. One particular problem I had came during fermentation. I felt I was unable to keep a constant temperature, and I’ve heard it’s a problem encountered by quite a few homebrewers.
So I did a little research and found out about a guy named Trevor Hubbard, a product engineer at Texas Instruments, who figured out a way to remedy that problem with the new BeagleBone Black, a single-board computer used by developers and hobbyists.
Essentially, he’s using the BeagleBone as a piece of process control equipment. With multiple inputs and outputs, he has the computer hooked up to a water pump, which circulates water through a steel coil that sits in his brew. The water also circulates through a heat exchanger, which allows him to change the temperature of the water flowing through the coil, thus giving him the ability to keep his beer at a constant temperature during fermentation.
The best part about all of this? He can monitor and control the system anywhere he has a computer and an internet connection.
The BeagleBrew is still in the concept phase, but Hubbard could be on to something. Check out his video below:
