Laser raygun boasts 300mW, hunts Klingons

Phasers come with two settings: stun and kill. [Luke] took this seriously when he put two Blu-ray lasers into a toy raygun. He picked up the toy from Amazon for about twenty bucks and set to work.

The laser diodes are both pulled out of a 6x BD-R burner, which we think is a pretty expensive source to scavenge from. [Luke] removed the toy circuitry, reusing the trigger, top switch, and battery pack. The two diodes are mounted on a swiveling carriage which is turned 180 degrees to switch between the two diodes. A boost driver converts the 3v from the batteries up to 7v for the diodes.

This is a skillful conversion and [Luke] should be proud. Don’t miss the video after the break and if you’re thirsty for more take a look at the last hand held laser we featured.

RGB laser

Last month we had the pleasure of bringing you [FireMyLaser's] green laser spirograph. Just green is great for a while, but why not add red and blue for a full spectrum of color! [c4r0] steps in at this point to bring us his red green blue laser. He dug around inside Blu-ray players and DVD drives until he had a collection of lasers, refractors, and other filters that fit his needs. With some careful toothpick alignment and glue, his setup was complete.

But then he went further by modified his galvo scanner to accept the RGB laser; requiring a custom circuit board and new software, both available on his site. The original is in Polish, but Google does a decent translation. Check after the jump for a video.

Blu-Ray laser keychain

[Jay] hacked a Blu-Ray laser diode into a keychain enclosure. He found a heavy brass keychain light from Lowe’s and stuffed the diode and a larger battery inside. The existing batteries weren’t powerful enough, so he drilled out the endcap to fit a 200mAh 3.6v lithium battery inside. He also modded the power button to only momentarily turn on the diode. With the larger battery, the laser can run for about an hour between charges. In addition to a Blu-Ray lasers, he also has versions with a 200mW red diode.
