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!
