Real Burning HOMEMADE LIGHTSABER!!! styropyro’s version

I’ve seen a few videos circulating the internet regarding homemade lightsabers, where one of the coolest designs I saw utilized a mini flamethrower. I figured I better show a video of my homebuilt version of the lightsaber…where my design uses a MASSIVE 7W blue laser. :D

In terms of building a working lightsaber, the two main limiting factors are beam confinement and high energy density storage. With the amazing Li-Ion batteries that the scientists/engineers have developed, stupidly powerful handheld lasers can be built, just like this one here. The issue then becomes confinement, which doesn’t look possible any time soon with a device like this. Oh well, my attempt is still bright and light things on fire!!

My device uses a Nichia GaN laser diode, which was overdriven to 7W of output by running it at 4.6A with a couple high efficiency buck drivers in parallel. An anti-reflective coated glass lens focuses the beam, and the whole device is powered by two unprotected 18650 batteries in series.

Upcoming videos are gonna be awesome…so watch out! Look for a ~150W laser bazooka, and potentially, a pulsed laser power by explosives!!!

I'm surprised the military hasn't offered you an engineering job your amazing keep up the good work

This thing is actually more dangerous then a lightsaber. Just hit em in the eyes and they're done.

Woah sweet thanks for the shout out! My little brother told me you mentioned my video and I didn't believe him haha. Your channel along with channels like ColinFurze and BackYardScientist are part of what inspired me to start my own!

Wait, what? You can just get a huge rod of Ruby? Ok then...

The scene where Gandolf says "Use the force, Harry"... That is the best sentence I ever heard...

"Where Gandalf says 'use the force harry'"

Plz no

[TheRealMisterJ]

Oh man I just found you through hackaday and had to immediately subscribe! Probly gonna be binge watching your videos all weekend. What do you study in school? Your an awesome inspiration dude!

[Legionclasscmdccwcjjspbvbl]

Dude, great work!
Your videos are almost an inspiration for a science student like me. To actually learn and APPLY science is so much better and so much fun!

The sad truth is that most of the students are just expected to score good marks in exams, i.e, no one's bothered if they can apply it in real life or if they can even recall what they've "learned", in the future.. *sigh*

P.S-> I subscribed :p :3

I have a friend that was somehow like you when we were teenagers, and finding your channel makes me remember a bit of his experiences. A kind of very good friend to have, definitely.
