I couldn't find any Web sites that had any technical specifications on how the optical sensor works, so I am not sure whether this idea might work. All the sites I did go to said the sensor was actually a small camera taking 1500 pictures a second. If this is true it seems like my idea could work." Has anyone out there replaced the LED in his optical mouse, out of necessity or curiosity? Have you found any good information about wavelength tolerances, voltages, etc? Anything that can handle a blue LED ought to have one in it, IMHO.
