@mike Yes! I'll write something up. The short version is that it's an ESP32 controlling a 100V supply via PWM with a MOSFET, and a simple shell script sending CPU utilization to @esphome via MQTT.
@mike@dan@esphome copper wire was sacrificed as an offering to the dark gods of nondeterminism and performance, while the incantations we're chanted. "Volt-ohm, ampere gaussae."

@dan @esphome I'm assuming that to connect the ESP32, PWM, and MOSFET to the rad looking steam gauge I will need a wand and cauldron?
Seriously though, super cool project and I'd love to see any write-up, photos, or videos you can make!
Thanks for sharing this!!
