     Checking things out with the thermal cam. As expected, there's heat leakage where wires and cords go into the chamber and at the joint between the top and bottom. I did not expect the controller itself to be so warm though

     I added a small bowl of water as a thermal mass to simulate having soybeans in the chamber. It's kind of wild how much of a difference that makes. The temperature in the chamber would climb to 120F in maybe 30-40 seconds when it was empty. With the bowl of water in there, it's barely at 93F after 20 minutes.

     Yeah, water has a high specific heat, but I didn't expect it to absorb heat from the air *that* fast

     It's still holding steady at 40 celsius. I think this is going to work!

     I might have a little bit of a problem here. The thermocouple I have is not of the correct type for this controller, so the temperature it reads is wrong, which would be fine because I can see what the actual temperature is, but it looks like I cannot adjust the internal temperature of the box to be much lower than about 50C, which is 10 degrees too warm for making natto

     Let's see how long it takes for the bulb to heat the inside up.

     Not very long at all!

     It's all going to go inside of this styrofoam box my brother found for me

     The plan is to use this ancient temperature controller and a lightbulb to keep inside of an insulated box at the right warm temperature (40C) for the 24 hours this requires

     I've gathered up all the things I need to try making natto this weekend
