I have a rotary controller for Jaguar (like these here: http://www.ebay.com/bhp/atari-jaguar-controller (http://www.ebay.com/bhp/atari-jaguar-controller)). Works awesome.
A few sites have directions on how to make these - looks real simple. (http://atariage.com/forums/topic/191571-building-a-cheap-rotary-controller/ (http://atariage.com/forums/topic/191571-building-a-cheap-rotary-controller/))
I wanted to make something like this for my MAME machine, so I got a detented encoder from Digikey, and tried to hook it up to a Zero-delay encoder (i.e., cheap Ipac) and it doesn't work like I'd hoped. I also tried a cheap Logitech USB controller with common grounds, like as was done in the instructions for the jaguar controller, but still, no dice.
I figured it would act like if you turned it a direction, it would act like you clicked the joystick left or right. It doesnt.
- turning it seems to treat the direction like it is being held down, and turning it back stops the turning. In MAME, it binds as 2 buttons - as if both directions are being pressed at teh same time.
Is there a way to get something like this to work, software, or something I can wire in? I really like the detented encoder feel for tempest , vs. the originals' analog control.
Is it just that the software for T2K was made to work with this type of control?

Looking through the links you provided, the Jaguar spinner and parts linked in that thread appear to use a mechanical circuit that produces two out-of-phase square waves like a trackball/spinner.
I think an optical encoder like an Opti-Wiz (http://groovygamegear.com/webstore/index.php?main_page=product_info&cPath=76_85&products_id=260), Opti-Pac (http://www.ultimarc.com/optipac1.html), or mouse hack should be able to translate the square waves into mouse X- or Y-axis movements.
