I may design a few modules that have one controller input such as Genesis/Megadrive and NES/SNES. Maybe others. They will also have a buffered controller output and 3.5mm outputs for each button.
The purpose it so that you can plug in the video from a game console and set up each button to trigger different visual effects while playing.
Does that sound interesting or not?
I know that I’ll need to optoisolate the controller output for safety.
What about the 3.5mm outputs. Should they be active high, or active low? Should they be 5v or 1v?
8HP should do it. Up, Down, Left and Right. A, B, X, Y. Start select and both bumpers. will I go with two boards sandwiched together and connected on the back with a ribbon cable. Maybe it could even be built in just 4HP if all the user needed was a controller input and u,d,l,r,A,B outputs…?
I have many other boards to send to the fab right now, so this may take a little time.
