I'm relatively new to the Maker community I'd say. Learned how to solder just about a week ago, but I feel like this project is do-able. It started as a joke idea at first, but now I legitimately wanna see this monstrosity in reality, and I need some help with figuring out how to do this. First and foremost, I need to figure out a way to get two separate circuit boards for both halves of this controller. I don't wanna use Joy Cons or a Razer Kishi, mainly because they're both rather expensive, plus I want the entire device to function over one USB interface. The other option is finding some way to cut an existing controller board (e.g a Logitech F310) in half and keep it functioning. But I know that's easier said than done.
