    can i make a laser pointer from an old cd player?
    i tore it apart and found this tiny board mounted with a small
    component "7283" that has a
    window and sits on a small brass heatsink..it butted up to a prism
    mirror etc and a lens sat on top.

    what volts does it need? where can i look it up?

    No - you can't. It's not a visible wavelength of the laser used in
    cd-player. :-(
     
  3. Sure ya can...as long as you supply your audience with infrared vision gear.

    It's an infrared laser, and it's dangerous since you would'nt have a
    blink reflex in case you point it to your eyes.

    However DVDs use a wavelength of 650nm, which should be red light. The
    laser user in writers are quite powerful, around 10mW. I never tried it
    though.
