Software Defined Haptic input Knob
youtube.comI made a circuit and wrote some simple software for for repurposing old hard drive motors as super smooth rotary encoders, but it never even occurred to me to use the same motor I/Os for reading the rotation speed and direction as outputs to create force feedback, or snap points like in the video. This is one of those instances of being completely humbled by seeing how someone’s idea, similar to my own, completely out does itself, implementing features I had never even dreamed of.
This was mentioned a week ago in this thread -
Amazing project, I would love to make one but it seems pretty complicated. Also the motor is not available anymore apparently.
