BoodschappenAplumb writes in with some handy information regarding using a mouse as a scanner we posted earlier:“A lot of cheap off-the-shelf optical mice use this chip. See this photospy I did of a Logitech I did a while back. Note: This chip is designed by the division of Agilent that was spun out and renamed Avago Technologies. See their Optical Mouse Sensors page for more up-to-date info, like the newer ADNS-2610 references.” Link.
