Question though--it looks like in one of the directions you might get a lot of slack i.e shaft toward the mouse--is that a problem or does the belt continue to ride the gears? I guess you could spring mount the mouse so that it maintains tension on the belt regardless of where it was positioned.
That's pretty damn cool, and to think I said it couldn't be done! :-[
You could further the idea on a 2 player panel by hooking up the 2nd mouse axis optics in some kind of custom housing for the Player 2 stick.
I decided I wouldn't bother with rotary sticks for the sake of a handful of games - might have to change my mind now... :)
I was wondering if you thought it would be easier to go optical. Instead of the belt system, put an encoder wheel on the bottom like a spinner.
Any thoughts?

I'm do plan on having two of these on the CP, so I'll be sure post more info/photos once the second joy is modded. My only question, so far, is in a game like Ikari, how do you assign the X-axis to P1 and the Y-axis to P2? I've had two mice hooked up at once in MAME and they both control P1 completely.
I am extremely proud of it, so don't laugh ;)
I just played Ikari and Heavy Barrel this weekend at the arcade w/ the rounded yellow joystick (which I think are not the original SNK rotaries, though)
I just played Ikari and Heavy Barrel this weekend at the arcade w/ the rounded yellow joystick (which I think are not the original SNK rotaries, though) for a comparison, and the only difference I found was the arcade joys clicked when you turned them. I'm working on a few ideas to easily add this function though. The game play seemed exactly the same.
... the only thing about this mod is "WHERE OR HOW TO GET THIS PARTICULAR 12 GROOVE GEAR ??"
What are the actual degrees, btw, in the characters rotation and how many click between each?
neat idea...
got a question... do you have any problems rotating and moving at the same time?
How about doing a super upper cut or any weird things like that.... could this cause the belt to fall off?
GREAT JOB!
The only weak point would be the pulley that is threaded on the shaft end, pulling/twisting too hard when switching from 4-way to 8-way could lead to trouble, but so far it hasn't. I'd like to get a metal version of the pulley to avoid this potential issue, but I haven't found one yet.
What about (rifle) drilling the control stick shaft and tapping it, then using a metal thread screw to secure the pulley so it can not be pulled off..??
finding that gear will be the hardest part for me.... since I don't know how to make one....
Stick this on the bottom of the t-stick and you're set.

You'd have to extend the shaft in some way, it's way too short to add anything substantial. As it is, this hack uses the pulley in place of the lock-nut as there isn't room for both.
You may even be able to use a tee nut to hold the wheel on there.
Hey, I believe I found a site that sells 12 flange/groove pulleys. See if any of these will work.

why not use something like a dremel flexshaft attached to a spinner?
Hmmm does anyone have any ideas for extending the shaft of a joystick - I'm looking to implement something like this hack on my J-sticks, but the shaft is short and has a different end than the t-sticks.
Basically the gear just turns with the shaft and the locking mechanism stays put...

Shaft coupler.
If you figure anything out be sure to post...I'd given up on this mod for the J-Stik...
I managed to hack a couple of J-sticks to rotary using a different method. I came across a couple of old rotary encoders from old peice of audio kit. I checked the specs and it claimed a "2-bit gray encoding" for the output - however it turns out (after a quick conflab with Andy from Ultimarc!) that this is in fact just a phase difference - which is exactly how analogue arcade controls work - so it works fine with the optipac. If you are interested I can track down some more details......
I tried this solution with no costs, used an existing joystick and an old mouse.
