Can you elaborate about the private channels and "DIY arms"? I'm not following. Regarding 2p games, it would just be like 2x the 1 player setup. You could also use 2 pins of a single ESP32 and 2 relays (or a dual relay board - still cheap) but I'm not sure if lnbits would auto-provision that so might need the arduino idea for that. I've manually provisioned an 8 relay version just to play with and have contemplated LN enabling my classic Gauntlet 4 player arcade. It's not hard. I'd be happy to help get you started. The first one is the hardest. 😁

Private lightning channels on a node that runs your arcade so you don't have channels go out of balance. I'm looking to solve th lnbits issue. So if each arcade just runs a basic node and wallet it could limit down time and failed payments. I also meant the guys doing DIY Atms that do lightning. I like your idea alot but I'd like to try where the arcade cabinet is a lightning node too vs just a wallet. If have any parts to recommend or even a cheap cabinet to start with id love that info.
