Star Citizen Mining Controller
Basic 1 Axis 3 Button USB Joystick.
you need:
- 1x Arduino Micro Pro <10€
- 1x Bourns PTL60-15G1-103B2 (Sliding Potentiometer with LED) < 3€
- 3x Keyboard Keys (afaik i used Gateron Blacks) < 2€ for 10 pieces
- some cables
- 1 micro USB cable to connect the Arduino to your PC This custom library https://github.com/MHeironimus/ArduinoJoystickLibrary
You can use any other Sliding Potentiometer as well, just make sure you use a linear one, and not some logarithmic one (they are used for audio applications).
Connect the wires, install the Joystick Library, flash the code with Arduino IDE. And it should work.
Also got a Case designed for it here: https://www.thingiverse.com/thing:4758367
