| | | Lasers are very well, and make cool toys. My cat loves to chase the little red spot on the carpet! But if you're talking about scanning or diffusing the beam, aren't you defeating the purpose of using a laser. If you want a cone, use a super- bright (...)

| | | | Maybe the robot could use the laser to draw spiro-graph designs on the wall, I'm not sure if the motors could position the beam that fast though. Joel Shafer joel@connect.net (25 years ago, 8-Oct-99, to lugnet.robotics)

| | | | (...) I was actually working on something like this using one of those cheap little $8 laser pointers. The idea is to use a pair of mirrors that can be rotated to specific angular locations to build an X-Y Laser Plotter. One mirror rotates (...) (25 years ago, 9-Oct-99, to lugnet.robotics)

| | | | | (...) 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)

We used the "big" lasers. :-) We also glued a small mirror onto a piece of aluminum foil wrapped around the end of an open tube, and placed it outside in the quad. Then we (...)

| | | | | 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). We then built a light sensor with an amp and speakers. when the music plays it turns the beam of the laser on (...) (25 years ago, 9-Oct-99, to lugnet.robotics)

Anyone got pointers to online circuits to receive and decode such data? I think a remote (...) (25 years ago, 11-Oct-99, to lugnet.robotics)
