Make Your Own Blu-Ray Laser Keychain!
PrintYou probably have an old processor lying around that you ended up modding into a keychain, but to take your geek cred to a whole new level, try wielding a blu-ray laser like a light saber the next time you fumble around for your house key.
Not only can it be done, but "jayrob," a DIY lasers expert, has posted a worklog of how he built his own using a keychain light made from a solid piece of brass that he picked up from Lowe's. In short, Jay stuffed a laser diode and a larger battery inside, did a little drilling, and ended up with the coolest keychain we've ever seen.
Read all about it here.

This beam shot is using smoke...
Yes, the laser is hazardous to the eyes, and proper eye protection is recommended for burning. (looking at the dot at close distance) A direct shot to the eye will cause instant damage. Care must be used.
405nm 'blu-ray' lasers are an interesting breed. Although dim in daylight, they are awesome at night! The make many things glow. Check out this video of how I am writing on a glow in the dark tile:

Here's a really great video that shows the burning power of a blu-ray laser. This is less than 150mW's. A customer of mine that used my 405-G-1 glass lens modification on a PHR build. (X-Box 360 sled)

Only an 80mW blu-ray build of mine lighting matches:

As you can imagine, this 268mW Key Chain build, is much more powerful than the lasers in these videos...

I wonder what kind of laser radiation that thing gives off...especially since ever DVD player I have ever opened up has a warning about exposure to it... Cool mod, but I'm just saying....

Keep in mind that picture is enhanced as he's shining it through smoke. It doesn't look quite that impressive in typical use.
