laser pointer

[[email protected]]

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. :-(

Sure ya can...as long as you supply your audience with infrared vision gear.

HAHAHA
Yeah I've also noticed some optical mice manufactured using these invisible
types too. My new Logitech MediaPlay cordless is like that.

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.
