USB Optical mouse as motor encoder

[Josuetas]

I am so tempted to open the one in my hand..... mmm....

Good luck

Anybody done any more with this? I'd love to use an optical mouse for speed measurement - but havent figured out whether the mouse figures out what is happening - or if it just sends out 'dumb' data (series of rough pictures) for the mouse drive installed in the pc to figure out, would love to hear from anyone who's made any progress

RodSTAR- I have played around some with the "guts" of a mouse! Inside, you will find something similar to this: http://cp.literature.agilent.com/lit...988-9774EN.pdf There are many different types of parts made by Agilent that can be used with a PIC. You are correct with what you say about using the sensor. You see this particular part has a serial output.

I need to get back to my own experimenting, and I am anxious to see how your project progesses. I will share any of my "revelations"!

And then there's the ADNS-2051 that also has quadrature outputs. I'm thinking this would be good for applications that do not require "imaging" or X AND Y measurements, but only simple linear speed and/or distance measuring.
