    My town has a recycling center. One of the designated areas is for
    discarding electronics. It has been a bonanza for me and a few others. I
    havn't bought a new computer in years. Why? Because so many perfectly
    good computers are thrown out because they are "full." The denizens of
    the town are free to take whatever they want. It help keeps the cost of
    disposing of them down. I keep the best parts of them and assemble my
    own and run Ubuntu on them.

    At any rate, I have been taking apart obsolete hard drives, CD-ROM R/W
    drives and other goodies. I take them apart for the wonderfully powerful
    magnets I find inside. I've found a number of good uses for them and th
    the other gizmos I find inside.

    I've also disassembled a number of the laser diodes mechanisms used in
    the CD-ROM drives.

    Has anyone found any interesting uses for the lasers in these
    mechanisims? If so, could you point me to a reference?

    Sure their are plenty of things you can use them for such as, laser
    lightshows (especially if you kept the power supply) .
     
  4. CR-ROM lasers are infrared!
     
  5. Maybe - if you have many of them - as a pump laser for a visible green solid
    state laser.
