HERE IT IS.
The reason I made this is that it turns out my basement apartment doesn't get much above 71°F, so I figured this would give the brew a nice boost. This is mainly just for fun.
After doing all of this though, and realizing that I like kombucha enough to warrant getting something bigger than a 1 gallon jar I may go with a different approach. I obviously can't fit anything larger than a 1 gallon jar in that crockpot. One idea is to use a heating pad such as this with a larger brewing vessel. I could measure the kombucha directly this way with the probe inside the liquid, or somehow find a consistent differential between the jar's surface and the liquid temperature and adjust based on that.
You can build something like this pretty cheaply it turns out. You can get an Arduino for <$9, a relay for $5, thermometer for $3 on ebay plus some wires, a breadboard and a single resistor which can all be had at Radioshack cheaply as well.
I've only recently got into kombucha, and as someone who doesn't drink alcohol but has always been very intrigued by the brewing process this seems like a happy medium. Just for fun, here's a short video of my yerba mate apple ginger kombucha being poured. I'm pretty proud of that fizz:
