So I'm thinking of making a wireless game controller with mx switches with a bluetooth numpad. Specifically, I'm going to make it into a nes controller. I'm making it as a gift for someone and I'm thinking of giving it to the person along with a nes emulator to play on the person's mac.
But since it has to be small, I'm going to chop it and I've seen people do it with fullsize keyboards but can you do it on a numpad and make it even smaller?
