    One random idea I had yesterday -- use them at a protest rally.

    Having every protester bring a laser pointer and point it at the source of their ire as they go past could make the point quite well. Particularly if they're just watching silently with banners saying something like "We're watching you" or similar.

    You'd have to make sure that you wouldn't injure the target with that many beams in the same place, of course - would getting 20 of those in the eye at once be harmful?

      Getting one in your eye at once is harmful. Focussed laser light can burn your retina, even low power light such as that.

    Mount one pointed at two rotating mirrors, so that the beam scans left-right creating a line, and each such line is scanned up-down. Ie, the left-right mirror needs to rotate something like 500 times faster than the up-down mirror, and that needs to scan at 24 sps. (if you have a 6 sided mirror, that is 4fps -> 240rpm. That means the small mirror would need to spin at 120000rpm! A bigger mirror with more sides is probably called for: a 30sided one "only" needs 24000rpm.)

    Now, turn the laser on and off in order to draw a 2D raster image on the wall. For extra-credit, implement both interlace (draw the top of the next frame while still drawing the bottom of the previous frame, using two laser pointers), or do color.

    Unlikely to ever be very good: you need some REALLY fast mirrors to get the framerate, and the timing tolerances aren't very forgiving. You can get better framerates by interlacing the laserpointers, and perhaps drawing each quarter-frame. Then alignment becomes a hassle.

  78. HOWTO: Detecting Laser Beams with a Linux Box by EMIce · · Score: 4, Informative

    I did this once. A cheap radio shack photocell tied to +5 volts via an active output pin on your parallel port, with the other end of the photocell going to an input pin on that same port, will cause that input pin to read 0 when little or no ambient lighting is present. When hit by a red laser pointer the resistance across the photocell is lowered and the voltage at the input pin ramps up above the binary threshold, to more than ~0.8 volt but less than 5 volts. Because of this, reading the input pin from software when the photocell is lit by a laser beam shows a binary value of 1. To avoid false alarms from stray light, I housed the photocell in a sealed, opaque box with a hole in it for the laser beam to enter and hit the photocell.

    A simple C program that reads and writes the memory address of the parallel port can detect, log, and act on these "laser trip" events, doing something as simple as beeping, or as complex as taking a picture and asking for a code. The program should write a 1 to the bit that controls the output pin you are using so that +5 volts appears on it. It should then repeatedly read the input pin you are using. When the input pin transitions from 1 to 0, even for a moment, you know the laser beam has been cut.

    The quick and dirty C code to do parallel port operations under linux can be found at here. For beginners I suggest you use one of control bits/pins as your output and one of the status bits/pins as your input. The data bits/pins are bi-directional and must be configured for input or output, and using them makes things slightly more complicated. If you want to get really fancy try using the parallel port IRQ to detect the transition from 1 to 0, this should save processing power by avoiding an expensive loop to check the state of the input pin constantly.

    If you need a little more background on the parallel port before diving in, check out this resource

    Finally, the above description is for a single laser beam. I used a mirror to bounce a single beam around, to get greater coverage, and to provide the effect of multiple beams in the presence of aerosol or powder. You should be able to support thirteen independent laser beams on a single parallel port, using the data bits/pins and the status bits/pins combined.

    A good optimizing compiler will not produce code that can overflow the stack.

This trick can work with many recursive algorithms.

  116. I'll never touch another laser pointer. by Peale · · Score: 1

    Back around 1995, two friends and I went to the movies. One of my friends had a laser pointer. Back then, these things were fairly expensive, and I was pretty impressed. They passed it back and forth a few time, shining it on the screen during the previews and the initial slideshow before the show started.

    I asked if I could see it, and they passed it over. I looked it over, shined it on the screen for about three seconds, was satisfied, and passed it back.

    About a minute later, one of the theater guys came up to ME and said that he would kick ME out of the theater if I proceeded to do it again.

    I replied that I had no laser pointer, and he proceeded to tell me that several people had seen AND complained about ME!

    So now I'll never touch another one. Who knows what will happen next time.

    Movie sucked too, IIRC.
