Andromeda Stardust Posted October 29, 2015 Share Posted October 29, 2015 DSC09900.JPG This device started life as the controller for a FORTRESS power chair (motorized wheel chair). I'm calling this definitely one I built. I assume the wheelchair joysticks used analog feedback mechanism. How does it feel rotating it? Is it stiff? Can you manipulate it back and forth rapidly? I have seen various pot-based industrial joysticks that could potentially be used for a pad hack project. 5200 is out of the question as it uses an RC time-delay circuit which is critically dependent on the exact pot values. However modern joysticks which use an analog thumbstick as a pot that inputs an analog voltage to a ADC could in theory substitute any pot value from 5k to 50k or so and still get accurate readings. It's also plausible a 5200 controller could be built by using a 555 timer in one-shot operation, but it would need to get a reset signal from somewhere with each josytick poll. Hall effect and others designed for MAME are equally useless without a detailed schematic and a lot of hacks. Quote Link to comment Share on other sites More sharing options...
