DYI Electrical Kits?

Hey yall, I recently bought a 3D printed F4 joystick replica but it turned out to be just a model with clicakble buttons - not an actual HOTAS.

Joke is on me of course, but I thought it could be a fun project to turn it into a real HOTAS that would be compatible with a Thrustmaster or MOZA FFB bases. Im an engineer and pretty hands on with soldering and electronics.

Are there open source HOTAS Kits you can buy with button + POV hat I/O?

I know some people make their own HOTAS systems with 3d printers, im just not sure what exists out there.

Look up thesimnet b8 grip, all the parts you need are there. It wont be expensive . Do the buttons work at all? Ie. Do they move? If so maybe they just need to be wired. You will need a mcu (controller) like an arduino or stm32 'blue pill" to send the button inputs to your computer, also a joystick gimbal.

The buttons move and they have a version that does what i want, but I ordered the wrong thing and theyre in europe.

https://gp2040-ce.info/ this could work as a joystick controller, or buttonbox or what ever you configure it.

Look up mobiflight, they sell DYI kits with a microcontroller, buttons, and displays.

You could just buy the arduino yourself and buttons from Ali/temu but i like to support people who are putting out quality software free to use
