Usb coin slot: for mame machines
I recently had an idea while I was asleep last night. I need to get it off of my mind while I can, before I forget about it.
What if there was a USB coin slot, that worked for MAME and other things by setting it to do a certain command. You could also set how many coins need to be inserted before it does that command.
Say, if you had stepmania for instance. In "arcade" mode, you have to hit F1 to "insert" a "credit". With the USB coin slot, you set it to hit F1 after it recieves its coin. You get what I'm saying? It would be a great help to people who are just getting into building MAME machines, and would certainly be a neat little USB toy when not using it for a MAME cabinet.
How would I do this? How could I make a thing like this? I need help, and suggestions on this. Hopefully, if I get enough supplies, I could do this. But I need some feedback on this one.
(sorry, the pic is just a regular coin slot. Nothing special.)
