YouTube laser hacker StyroPyro demonstrates his custom-built a 3000 mW green laser, housed in a machined aluminum Lightsaber body. It looks pretty neat from the safe remove of your iPad screen, but if you see a Star Wars geek whip one of these out from under his Jedi robe and fire it up at a fancon, you’ll want to run like hell. Unlike that ‘more elegant weapon for a move civilized age,’ this laser torch has an infinitely long ‘blade.’ In theory, anyway . . .
In practice, this overpowered laser can cause skin burns or permanent blindness to anyone it hits (depending on the duration of exposure) out to a range of several kilometers. You can deflect it with a mirrored surface, but you can’t use another laser to parry it. Unless you’re Mace Windu, that is.
The blue laser packs 3000mW, quite a bit more than the standard red laser pointer you use to bug people at the movies. It uses two lithium-ion batteries to maintain its worrying burning power. Styropyro, who is known as the DIY Laser Guy, said he doesn’t normally enjoy owning or operating a laser this powerful, but took one for the team so he could entertain his fans by setting a few things on fire…
As demonstrated in the above video, the laser doesn’t vwinggg around as it moves through the air like a true lightsaber, nor does it start instantly or cleanly slice everything in half. However, the laser saber does quickly burn a hole through and set fire to most things put into its path, including paper, electrical tape, cardboard, a ping pong ball, and a thin wooden splint.
