I was wondering since I have a spare dvd player and was looking for a little project. Is it possible to take the dvd eye that reads the dvd and turn it into a laser pointer powered by a battery?
Answer
Yeah, DIY lasers are big on the internet. Lots of people do almost exactly what you've described, although I think they usually use DVD burner diodes. Those have the power to burn black tape, pop balloons, etc. I saw one tutorial where they built the laser into and old NES zapper. Wicked! The main point is to rip your player/burner open and get the laser diode out, which basically looks like an LED. You need to buy a housing for the diode, which will have a lens on it to focus the beam. After that you just wire up your power source, and that's it. It's pretty fucking easy to make a laser. If you can get a Blu-Ray diode, then you'll have a purple laser that makes things fluoresce, or glow, when it hits them. If you want to do this for the fun of building your own highly dangerous laser, then you're on the right track. Search around for tutorials with specific instructions and pictures. If you just want a laser that can cut things, you can also check out the stuff at www.dealextreme.com. Those things can blind a small child in seconds!!! Have fun.

can i use a laser from a cd player to do laser hair removal?

I thought maybe i could make a cheap hair removal device by using a cd player.
Answer
Nope, the pickup laser in an optical drive is not powerful enough to do anything apart from shining a dop on your skin.
Can buy a cheap laser pointer for a couple of bucks that'll do the same thing.
And no, the write lasers in a CD/DVD/Blu-Ray burner aren't going to work since that's not on the correct frequency to damage the hair without damaging the skin.
It would work to remove the hair, but you'd have more scarring on your skin than Freddie Kreuger.
Not quite the impression you're going for.
I would consider the hair-removal creams as an inexpensive alternative to the laser treatments. Sure it won't last nearly as long, but it's a lot more affordable than the professional laser removal while at the same time being a lot safer than burning it off with the wrong type of laser.
