(...) SNIP (...) SNIP Big rocks, too. :>) The problem is not so much the laser, as it is your scanning. Unless you are projecting against a phorescent screen, there is no "residual" trace, regardless of power. It is the speed at which the eye can't (...) (25 years ago, 9-Oct-99, to lugnet.robotics)

One of the early things I did with my laser pen was rubberband one of the 5 stud long "helicopter rotor" plates to the side of it. I never got it balanced *perfectly*, but it was close. I then stuck the axle from the older 9 volt technic motor (...) (25 years ago, 9-Oct-99, to lugnet.robotics)

Okay. The adress for that OpteK Technology is www.optekinc.com . They have other sensors too, for magnetic and infared needs. Intresting place to go for position sensors. The products have possibilities. Andy (25 years ago, 9-Oct-99, to lugnet.robotics)

HI, Me and my friend did this thing with a laser pointer where we connected it in parallel with a audio device(using a cut headphone cord).
