Hello, fellow Passenger !
Welcome to ShrtBus Modding Group! We are a group of Modders, Hardware Hackers, and Reverse Engineers. That build custom controllers, mod consoles, and so on.
You can find our main gitrepo on our on Codeberg.
If you want to get started with Modding, building custom controllers with ardunios, or something else. I would checkout our blog. It has some great info about how to get started, our thought process and even where we buy our parts!
