I ordered a U-HID G for testing next to the gamepad idea. I'm marginally skeptical of accelerometers, but if it works as promised, then it'll be way easier to implement and calibrate. If nothing else, it'll be fun to play with, even if it doesn't end up in the cabinet. I'm sure I can stick this thing in something else and have fun with it, if it doesn't do what I want for the cabinet.
The board also allows you to assign the Z axis to a pin (instead of the accelerometer - at least, I think that it does, anyway), so you can grab a potentiometer from your favorite electronics store, fire 5 volts through it to the U-HID board, and connect that potentiometer to your plunger via an arm (like Rawd did in his
test video), and you have an analog plunger, too. I will be messing with that idea to see how well it works. If it does work as planned, then this would be easier to set up than trying to get one of the analog sticks on a gamepad relocated near the plunger (or sticking the whole gamepad near the plunger).
I imagine it'll be a few days getting here, so I'll continue to screw around with the gamepad in the meantime, as time permits.
