Quick 4h Build – PID Fan Controller
Posted on 2020-12-05— 3D Printing, Projects
I built a PID-controlled fan and temperature controller for my printer enclosure in about four hours using an Adafruit Feather, DHT22, OLED, MOSFET, and a PWM fan. I walk through printing the case, wiring, firmware setup, and assembly—read on if you'd like to build one yourself.
