thingiverse
Powerbox with 2.1mm DC connectors incl 2 0-12v variable outputs for 12v dew heaters. BOM 1x Arduino Nano 1x 1.3-inch OLED 128 x 64 screen (SH1106 chip) 2x KY-040 Rotary Encoders 2x IRLZ34N Mosfet 8x 2.1mm female power connectors (for panel mount) 2x 3pin WAGO connector 2x 5 min WAGO connector 4x m3 8mm socket screw 4x m3 nut Small PCB breadboard for holding mosfets misc cables Arduino Nano holder was glued into place after rotary connectors where in place . Wago connectors (5pin) where glued in place. mosfet holder was glued into place after everything else was in place. Lid is glued in the current iteration, might make a version with screws. The Dew Controller part is a mosfet that limits voltage to the output, controlled by an arduino nano with rotary encoders.
