300 mW is an extremely dangerous level of power for a laser. At that point it can reflect off of any remotely shiny object (or even the air) and cause eye problems if you don’t have eye protection. I can’t wait until somebody tries this “hack” and goes blind from it.

@kirov: I’m surprised it hasn’t already happened. I cringe a bit everytime I see a vid like this. One can only hope that those that are inspired by these projects also read up on safety and understands just how dangerous these things are.

Wear blue or reflective mylar armor.

just sayin’

so the blue from the blu-ray and the red from the dvd part, cool.

when i read the artical i assumed both were blue, this is slightly mroe interesting

It *would* be a hack if this guy figured out how to get a 2 micron (eye-safe) laser, but that’s another story. ;)

What impressed me most was his ability to refrain from yelling “Pew pew pew!” during the video. Sir, you are a stronger willed man than I.

Set phasers to “blind”.

Since we’ve been on a ‘whining about safety’ kick the past few days: This guy ought to be concerned with skin exposure as well. There is a considerable amount of high-power UV light being emitted from one of these. Not necessarily good for you..

In the vid he points it close to a picture with a glass cover and metal frame. To no avail I waited to hear screaming. The juke box could have blinded his ass to. =) Stunning, tazery, panicky blinding machine babble? Sounds awesome.

addendum [dumb?] If I keep on seeing submissions like this, I might start think this site is associated with the Darwin Awards website.

Hey, I am glad some of you like this hack! I am not some hack with a hack. I have been building & learning about lasers for many many years now. While using high powered lasers I always wear multi-wavelength protective eye-wear to prevent accidental eye injuries. It is nice though that so many of you have made the *Blind* assumption that I am so reckless. I would hate to see any of you try and cross the street in a major metropolitan area or dare to drive a car…Might be too dangerous for you to get through the experience.

hahah i got a “laser hair removal” banner ad with this

wait what was diffusing the beam in that vid ?

Gives a new meaning to “You’ll put your eye out!” If it is so lethal, why doesn’t the military use this technology to blind the enemy?

The safety police on Hackaday are out in full force today! Don’t forget to wear a helmet when you go outside, a bird might fly into your eye.

Do you understand the significance of this?

This “Luke” person is attempting to reverse-engineer twenty-fourth century technology by using current twenty-first century materials. This is dangerous.

I’m reporting this to the Starfleet Temporal Investigations Unit.

ive been considering making a quad blu ray laser that condensed the beams to a center point and then had a 150-250(dvd burner i think) laser in the center but never had the money to do it or do it safely…

Bazinga

optical isolation! I am so glad I’m not the only one that does this in their everyday life!

@ITIL Prince: You are correct, sir. The STFU is no doubt investigating this “Luke” character.

@Luke: Please stop what you are doing at once! Humanity is not ready for this technology yet. Starfleet will send you to the New Zealand penal colony if you do not comply.

I need one of these…

…maybe I could mount it on the automated turret I’m building…

Peace,

…but not literally…
