This is a personal project that I started last year and have finally completed. It is a controller for KSP or similar simulators, although it can also be used for other games.

You will need the following hardware:

• Teensy 2.0++ or compatible board
• 9x M3 inserts
• 9x M3x10 countersunk screws
• 2x JH-D400X-R4 joysticks
• 16x mechanical switches cherry mx/gatheron style and the keycaps you like.
• 2x EC11 encoders with push button
• 2x MTS-203 three-pos switches

The code is entirely created with Claude 3.7 Sonnet, so it might contain errors, but it works perfectly for me. You can use software like Joystick Gremlin and vJoy to fine-tune the behavior. You can find the code, pinout order and diagram in the attached documentation.

The design and organization of the interior are up to you. There are two holes, one at the top and one at the bottom, for routing the cable or installing a fixed connector.

03-06-25: Updated code for better encoder handling. Next update I will upload to github.
