Sweet. What I really wish I could find is something that provided haptic feedback. I was just on the mp3car forums and saw that there was something in development years ago, but it doesn't look like it never went anywhere.

All this stuff is WAY beyond my understanding, but not beyond my interest.

yeah, i tried getting my hands on that a few years ago and couldn't find one anywhere.
An option i was looking into is hapkit:

i think you can replace the lever with a knob edit: it would be difficult to replace the lever with a knob, the lever has a force sensing resistor (increases voltage the harder you push on it). that is what gives the micro-controller the info to know how much to resist your movement)

i have one of the low resistance motors, i just dont have enough to devote to a project like that right now.

a possible option for a cheap force changing input device (not haptic though) would to have an encoder that was free spinning (or use a cheap hall effect sensor that can detect rotation of a magnet) and then have two different cam profiles (possibly a geared tooth and a lobed cam) then just have a servo apply a sort of springed tooth to give you different force feedback.

edit 2: another idea i had was to use a disc brake assembly from an RC car. you'd then be able to adjust the force required to spin the knob based on how much you spin it.



I think this is getting far away from the OP's original thread. wonder if the mods would move the non applicable posts to a new thread?
