Make a laser lighter from the old DVD pisalka own hands ... :)

UPD: Even a 4%-ing any reflection from the glass surface can give a bunny, which is irreversibly ruin the eyes. The effect will be felt in two years. The eye adapts to the loss of individual sections of the retina, but still a pity. Bunny, as we know from the same school physics course, can travel at speeds greater than the speed of light. And the eyes, brilliantly adapted to all and sundry, no time zadiafragmirovatsya (the pupil does not shrink), and save yourself.

First I want to just remind you that, if with his hands or his head is not all right, you can easily burn a retina of the eye! I've occasionally catch all of the reflected laser light spots :)

So.
Take a writing DVD-ROM (the more he write speed, the more powerful laser)
I found in my bins a very old ...
Parse.

Find the head with lenses and lasers.

Uproots her.

It has more than one laser, one of whom is responsible for the record, it is we need to extract.

As far as I understood from the DVD lasers are designed to 5V, but they're working in a pulsed mode ... so that in their experiments suggest starting with 3 volts and just think about the cooling of the diode. In ongoing work I have it heated to more than 60 degrees ... A laser overheating ends in tears ...

Pin assignment see below why you need a third ... I do not know.

As a result suppressed by the laser 4.5 volts on three AAA batteries and setting the laser to the focusing lens (extracted from the same DVD-ROM of a corpse) that is capable of beam at the focal point to light a match and cut black paper ...

More likely it will gather into the body of the flashlight ...

And imagine what would happen in a year when the boxes will roll cutters Blue-ray, with a much more powerful blue laser ...

Pliz tell me when do Jedi laser sword, and I've got out there with a few small problemok ...

PS Be careful with the eyes ...
