School project - help laser pointer?




Voldemort


I need to make a some object that shoots out light... therefore a laser.... lol but anyway

I need step-by-step instructions on how to make a fairly easy laser. I know you need a diode from a cd player but I need instructions on how to attach the wires and other things... I plan on buying the parts online.
I want to know how to do it and plus if I make it out of nothing and retrieve the parts and put it together myself I have a sense of accomplishment

Plus it'd be way cooler than buying one... more fun...and no one else in my grade could begin to make a laser pointer

Best answer

as long as you DO have to put it together



Answer
cd diodes are IR so you will no be able to see it. If you own a digital camera and it doesnt have a IR filter you would be able to use it to see the light.

You would be able to see a blueray diode but they're not easy to come by so you would have to buy one off ebay

The main problem with both is the lenses on the lasers are focused around inch away from the diode to read/write on the disk. There by they really dont look all the much like a laser but more like a led.


You can buy something like this
http://cgi.ebay.com/150mW-405nm-Blu-ray-Blue-Violet-Laser-Diode-Module-Kit_W0QQitemZ270430046283QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef6e3084b&_trksid=p3286.c0.m14&_trkparms=65%3A12|66%3A2|39%3A1|72%3A1205|293%3A1|294%3A50

Comes with a diode and a driver that would have to be wired up. There are other kits like this that are cheaper if you look around.

Is it possible to turn a dvd eye into a laser pointer?




Jack


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.
