i would like to build an absolute rotary encoder. But I don’t like the cheap once with light sensors.
The other day i saw a guy who hacked a mouse camera with an arduino.
I think it would work great to pick up Graycode of a rotary disc. But the guy only got 10fps(due to the camera) which isn’t fast enough for me.
What also might work is a tiny line scanner with high fps.
Are there any cheap high frames per second, low resolution Cameras/line scanner that an arduino can still handle to process? (as many fps as possible…30 fps ain’t enough either!)
I know video can quickly get out of the league of an arduino…but maybe this could still work because of the low res (just e few pixels to get like 12bit Gray code).
