Hi, Rebecca Minich here! I’m moonlighting as the CircuitPython wiz Scott Shawcroft today so I can share my Kombucha thermostat project. If you are a fan of sour, this fermented drink might be for you. Unfortunately, it comes with the health food price tag of $3/bottle. Brewing it is much cheaper and way more fun!
For a healthy culture and delicious tasting ‘buch you’ll need to maintain a pretty high temperature (~77F/25C) while brewing (5-7 days). Keeping the brew that warm is challenging in colder climates. With a little help from a terrarium heater and some electronics, I created a thermostat for brewing year round. Check it out below!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
