With two way digital communication what are your modding plans?

I think the best option for mirror position feedback would be to use a patterned disk attached to the thread and bounce a laser off it to focus on an optical mouse chip. And there you have it 2000 dpi resolution for about £1 sterling (just cannibalise a mouse)

I think you're on to something, but not how I read your post. Rather than use the sensor directly from an optical mouse maybe we could use the whole unit, after all the mouse just sends movement information back down the USB not the RAW data it collects.

I'll put my thinking hat on as I've never worked with data from a mouse.

EDIT: Just the thing!
