720 revisited

And I was wondering if Oscar's wheel is as big as the 720 wheel, but am guessing they're close to the same size. (I have a badly warped 720 encoder wheel.)
The Oscar's DOT repro wheel looks a lot thicker than than the 720 wheel, and the internal diameter of the center hole in the 720 is definately bigger than the DOT's. That's all I can tell from the pics.
I was wondering about the actual details.
But, yes, that 72 teeth is very promising, if not for Oscar to use for a 720 repro, then for me to try to hack onto one. I'm debating if I want to get a DOT repro from Oscar, and before I deside to get one, I want to know if I should get a "spare" wheel to try to hack into a 720 controller.

you know what's crazy? I work with Dave Ralston... one of the original designers of 720...

A bit OT, but.. one of these CPs is currently @ $150+ with days left to go O_O
Even for a 720 CP, that's pretty damn high.. I feel bad for the guys with real machines trying to get a new CP on eBay :P

I have an idea! That might just work pretty well!
1) Hack an analog controller. Finding the ball handle on one might be the hard part... but that will be worth it I would guess...
2) Get a lazy susan with the center whole big enought for the joystick to move around in without touching..
3) attach a thin plastic over the lazy susan and attach.
4) Cut a whole in the plastic to put the joystick through... so it's only at its edge.. And it will rotate around the entire area.
done!
The best case would be something similar to a real 720.
1) make a circle with a whole on it at the edge. The joystick goes through the whole.
2) make another plastic square or whatever with a larger circle cut out of it (that the other one will fit in
3) make ANOTHER plastic or metal (or your control panel) with a hole in it so that the one around the joystick cant pop out. This is what holds everything down.
This is how the original keeps it turning. It kind of smashs the parts together.
But with the analog being easier to configure / not deal with directions and the extra true north encoder wheel... this seems to be the best.

Ah, right. Now I remember. :-[

I almost have all the parts. I'd like an extra spinner knob though, but I can get another one in the future. My Idea is to have a removable joystick part so you can use the spinner as normal. All I need now is a mouse to hack (which I am not good at) and a way to mount the second axis on my oscar spinner at due north.
actually, I might be able to use my trackball mouse hack for now. I have a couple of extra wico IR boards to play with.
