It's been nearly two weeks since I last worked on this. This is a typical pattern for me - do a lot of work really fast, then stop completely. But I'm not going to stop this time!!
In my last update, I had gotten to a point where the device would sense the water temperature but then compensate too much and end up oscillating between freezing and burning. This time, I have three next steps:
1. Add more time for it to wait for a temperature change before compensating again.
2. Brace the servo
3. Make the device more physically robust

Ok, I'm getting irritated. I pulled out my awesome new jumper leads and attached them to the temp sensor. To make the temp reading quicker, I used silicone glue to waterproof the sensor connectors. Sounds awesome. Now the sensor gives completely erratic readings. It likes to stay in the negatives, and has now been stuck on -50 C for the past few minutes. WTF? I don't want to rip off the glue after I got it so perfect. I have no idea why this is happening!
