beatmania -> PSX control panel adapter?

[taiki]

A few months ago I gutted a beatmania control panel and justnow have gotten around to trying a few things to get it to work as a playstation controller.  The buttons are simple enough, as they're just simple switches.  The turntable however, is an optical spinner, and I need something that'll take the input from this optical spinner and turn it into "turn x switch on" or "turn Y switch on".  in this case, the up and down switch on the digital part of a playstation control pad.  Anyone know of any pre-built circuits that'll do it?  or any other ideas?

Your best bet is to gut a PlayStation Beatmania controller. The official ones by Konami and ASCII use an optical spinner too. Be weary of the cheap third party controllers as they may have choosen a cheapish way to implement the turntable. Since you gonna butcher the controller I'd suggest getting one on eBay

Btw, do you have a working arcade optical sensor for your arcade turntable? If you are not using it I would love to make you an offer as mine got busted during shipping

i have two spare optical sensors.  If I don't fry them out during the course of modding, sure!

Yeah, a cheap 3rd party one isn't the way to go.  Last night I tried hacking a rave discman, and that didn't turn out well. 

Atleast though, Now I have some idea what the pin out is on the optical sensors.

I wouldn't try to hook the optical encoders up to the circuit in the controller, I'd hook up the circuit's optical encoder to the turntable.  But that's just me.

Problem is that they're two vastly different kinds of encoders, physically.

but the theory is is that they work on the same principal

well, I mean, you might be able to find a way to mount it to the shaft, swapping whole encoder for whole encoder, not just part.  It seems the easiest way to do it to me.
