What Could You Do With 120 Laser Pointers?

lazed-dazed asks: "I've recently come into possession of a large number (120 of 'em) of keychain laser pointers (minus the fancy diffraction adapters, though the specs are the same). So, Slashdot, I ask you: Can you give me any project ideas for these low-wattage bad boys? Holograms? Fancy cigarette lighters? Laser cannons? The crazier, the better! Oh, and don't bother suggesting cat toys."

    Just buy 120 sensors which can recognize laser
    light, a ton of wires, a loud electronic horn,
    and a computer to connect them to.

    Then you can build your very own 'I-have-
    something-very-expensive-to-protect'-roo m. Put a
    tux or your favorite CBN-Shrine in the middle and
    place sensors and lasers at the walls crossing
    the room in a wild way.

    Congratulations, the room is now safe from
    intruders. (at least you will hear them if they
    come.)

  5. Re:Point them to a single location... by Anonymous Coward · · Score: 5, Funny

    Funny. No really. The first time some idiot let me use a laser pointer was on the roof of the dorm, at midnight, when the power had gone out. I would just silently point it at people walking to and from the dorm. Then, when that didn't work and they started to run, I'd just shout, "NO USE RUNNING. IT'S A HIGH-POWERED RIFLE."

    Oh well. One person's funny, is another person's terrorist threats. But back then you wouldn't even get written up for crap like that. Of course, that might have been because I gave them someone else's name and room number.

  9. The Ultimate Laser Pointer by fuzzybunny · · Score: 5, Funny

    You will need:

    322,951 crewmen

    Several million tons of quadanium steel

    Approx. 950,000 troopers in cool white plastic uniforms

    One (1) small moon at the outer edges of the known galaxy at which to construct the thing.
    Here are some technical specs, and a handy diagram.

    Basically, you do the following:

    (1) Use all the steel to build this gigantic metal ball, with a dimple on one side. You use a huge rubber band (available at your friendly neighborhood hardware store) to hold the laser pointers together, and put them in the dimple (make sure the batteries are always charged.) Get all your 1.5-odd million crew guys and troops on board, and fire the bitch up.

    (2) ...

    Attach about 30 of them to two gloves, and go dancing.

    Attach an AC adapter and mount a row of them above the front door, aiming down.

    Give them away at a local school. The teachers would love that.

    Drill holes into a thick wooden board, mounting the pointers upwards under a sheet of transparent plastic or glass. Sacrifice an audio LED controller or two to synchronize the beams to music. Learn to dance.

    Attach them all to a single trigger, and mount them together with a large amount of tape. Keep in your glovebox. When someone cuts you off, aim at their rear-view mirror.
