Well, I didn't even take that into consideration when I tried it. It
worked, and I haven't noticed any change in the performance of my sensor.
I'm not exactly sure how the sensor works, but I'm pretty sure it's a CdS
photoresistor, so the laser should only lower the resistance to a certain
point, which I'm sure is indicated by a 100 level reading on the light
sensor. There is a minimum amount of resistance, and once it is reached,
no matter if the light comes from a flashlight, a laser, or the sun, it
shouldn't damage the underlying circuitry.

Disclamer: If this damages your sensor, sorry but you did it, not me. :)

| Hi I was wondering if these little pocket laser pointing devices can damage the RCX infrared sensor and also the light sensor? Anyone know about this. The laser would be fun to use as a trigger device for the RCX, of course if it only works once.... (...) (26 years ago, 17-Dec-98, to lugnet.robotics)
