Just got done brewing!
Here are a few more pictures.
The TMP36 sensor leads were isolated with electrical tape, then heat shrinked and sealed with black RTV silicone for moisture resistance.
The carboy sensor is taped to the side of the carboy and insulated with bubble wrap. The Arduino code takes precautions against condenser short-cycles and temperature overshoots.
This is my first all-grain brew since 2007, and I’m happy to get back into the hobby with parts from Adafruit! 🙂
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
This is awesome! I love seeing a combining of electronics and homebrewing, as they’ve been two of my biggest hobbies in the past 6 years. And I love the enclosure you used! Great job!
Well! *hands on hips*
“I hope you brewed enough for everyone…”
Check out the BrewTroller and FermTroller open source projects. BrewTroller is a brewing control system for all-grain brewing that monitors temperature and volume off your HLT, mash and kettle and controls heating elements, valves and pumps. It also performs temperature and volume calculations for your recipes.
FermTroller is a multi-zone dual stage temperature controller for fermentation. Both projects are based on the same hardware design and support a network interface for remote monitoring and control.
We welcome additional contributions from developers who are interested in making the projects better.
