I built a sim racing setup slowly over time, and using a VR headset instead of a screen has been a game changer. It's actually fun again. Downside is that I don't think I can ever go back to racing on a regular screen anymore.
i also have questions. was the fridge "smart"-capable prior to the esp32 mods and you just replaced the factory controller with your esp32 stuff, or youre saying you wired in the appropriate circuitry to replace the pressure-controlling thermostat with your esp32 stuff?
