For this episode, it was is Raspberry Pi night. And it was Mikey’s birthday. So we went with a topic of his choice and began a discussion of automation for brewing and fermentation using a programmable controller that you can buy or build yourself.
We started with brewing automation (aka hot side control) by calling up Corey Simonson from Brewtronix.com. Corey is the brains behind the Hosehead brewery controller; a Raspberry Pi based controller that comes in several versions that include:
a full electric model, capable of controlling a boil kettle and HLT
a hybrid controller, capable of controlling one element in the HLT, or 2 pilot valves on your propane burners
a recently released Hosehead Uno BIAB version
and the X4BL quad controller---which piggy backs to the original and controls a total of 4 elements.
And all of it runs using either the Strangebrew Elsinore or the Craftbeerpi applications.
Then, explored the cold side of things by discussing Raspberry Pi based fermentation control with friend of the show and NHC gold medalist, Mike Treadway. You may remember Mike from our discussion about making small changes to produce better beers way back in episode 25. Well, he recently gave a great presentation for the Cap and Hare homebrew club based on his Raspberry Pi controller build and tonight he’s here to share it with you so you can add in something new to keep making better beer!
