I don't have the tools to make a controller box but might be able to get help from a friend. Anyone got an idea for hacking something existing to use as a controller box? I have had a quick look on Amazon for a plastic diy project box but they look a bit small (200mm x 120mm x 75mm).
I made a comment a few spots up that has a couple of Aliexpress controllers which should work great for this. Ive bought from the seller, Marco several times. He uses authetic arcade plunger style micro switches in his gear which should wire up nicely to the boards.
