I'm losing momentum on the FilaBilly Humidor. I think it's because I'm doubting that the whole thing will work. Anyway, today I spent a few minutes on it. I drilled the holes, fitted the brackets, and attached the center LED channels. Everything went together exactly as planned/prototyped. It even looks good (to me).

@3dprinting The HÖGBO doors are on, and I threw a few spools of filament in to see what it looks like. That's quite a gap between the doors, about 8mm.
I got busy and installed the doors today because I saw this on Reddit.

@3dprinting I cut the hole in the FilaBilly Humidor's side today. I used it as an excuse to get a new toy-- er, tool for the workshop. Jigsaws have come a long way since my 1985 model.

@3dprinting I'm declaring victory. The overshoot is harmless here, and the oscillation is gone. The cold temperature stays safely below 0℃
You can see that the temperature fluctuations are at the resolution of the thermometer, ±0.1℃.

@3dprinting The FilaBilly Dehumidifier's PID controller looks a little under-damped. I tuned it using ESPHome's built-in Ziegler-Nichols tuning. Now I'm going to try to hand tune it a little bit. (I have never tuned a PID controller before. They are black boxes to me.)
It is trying to cycle between 15 minutes at -0.5℃ and 5 minutes at +2℃. That lets it defrost.

@3dprinting This morning I soldered the FilaBilly dehumidifier PCB. I need to crimp up some connectors, reprint the orange standoff/surround (it's like 0.3mm too tight), and finish the firmware. Then it'll be system testing time! I already know the ESP32 boots, either from USB or 12V power.
I found out about r/PrintedCircuitBoard yesterday, so I'll ask for a PCB review there, even though the board is assembled.
