I was sort of expecting it to be much faster - guess the laser not overly powerful.

Would be interesting to see the same thing with bullets, arrows from a crossbow, etc.

/was also expecting all 100 to go off in a microsecond.

well, the laser may be travelling at the speed of light, but i'm guessing that it takes a few nanoseconds for it to burst each balloon, hence the delay.

For something that was made to read a blu-ray disc, I'd say it's pretty powerful.

FTFY.

Lasers popping black balloons is less impressive than bullets going through a tin can.

This is impressive: Slingshot vs Zombie

Skip to 2:22 for the good shiat.

So he includes a reverse playback for filler, but doesn't bother to add a slo-mo playback?

Want to see a direct link to the video instead of some worthless passthrough page?

Tough shiat.

Holy crap!

I liked the video with alcohol and fire!

aaaaand that right there is why i'm going to build a high power array laser out of nothing but used CD-rom laser diodes.

yes it will take a lot as those top out in the 1/3-1/2 watt range but it'll be worth it, so worth it.

and busted CD drives are so plentiful you can get entire pallets of hundreds for pennies per CD drive.

and there's all kinds of motors and other stuff too, so you can make the aiming array and everything else you could want.

Needs a cat or a dog in the room... just to see the reactions.

I have one of those lasers....
I've been meaning to pick up some balloons and try this......

But what the hell can you do with it?  Create a light show?

Point it at police helicopters, of course.

well, as i'm going to route several thousand diodes ultimately through a collimator and lens set, not so much.


more like burn through 1/4" steel, or fire lasers at the sky till mighty zeus shoots lightning back at me, stuff like that.

If that's what you are aiming for, I think you'd be better off getting one of the Blu-Ray diodes and building a capacitor array that charges up and fires a strong beam through it.  Wire it right and you can make a 10,000 watt laser for an instant.  Of course, you'd have to hit it repeatedly.  Lasers aren't lightsabers - they still have to heat up material to burn through it.  But if you can build an extremely temporary battery to fire the laser all at once at 60KHz, it wouldn't take long to burn through something.

not quite what i'm after at all. i need sustainable output that won't burn out anything. i'm planning around a laser CNC table, not a toy to burn stuff with.

making the ion track to induce lightning strikes, that's for shiggles.

Lets see him do that with mylar balloons.
