Darned fine idea!
2) I think I need to find a way to return the wheel to the home position for non 360 deg games. I am working out adding a shaft from the back of the Optical Mask which will coil up a bungee cord or someting so when you let go of the wheel it will return to center. The key is I need to make it really easy to disengage for 360 games.
I am going to use the exact same idea on my Oscar Spinner rolling against the metal weight. This should allow me to play Anakorid and other paddle games more realistically. I'll let you know how it turns out.
If you can figure a good way to extend the shaft beyond the encoder wheel (or should we call it an encoder
cup when it's shaped like that?), then what I'm envisioning is a shaft extension with a pin driven through it near the far end, that sticks out 1/4 inch or so from both sides. Then find a length of pipe with an inner diameter sized to fit snugly over the shaft extension. Cut slots in one end of the pipe to fit the pin that's sticking through the shaft extension, so that when the pipe is slipped onto the extension, the pin and slots force them to turn together. Rig the pipe to whatever spring system you like (I think a rotational spring setup like in a Starwars yoke is good), and just slip it on or off the extension whenever you switch game types.
(Hope that makes sense- it's always hard to put a picture into words.)
You probably already know this, but for others that might not, Arkanoid didn't have a paddle with a pot like Pong had, it had a full 360 spinner. But it was a geared spinner, and a paddle might actually play better than an Oscar Spinner. Curious to see how that turns out.
