PowerBox for Telescopes with Dew Controller

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.
