Surely everyone remembers the Lego chaingun that was posted here a while back; well, at the insistance of a certain member of these forums I have built my own. Now it isn't quite so good as the one I based it off of; I didn't have enough parts to make 8 barrels, or even 6 (which is what I was going for). So it only has three barrels. Also it has a relatively poor rate of fire (maybe 2 or 3 per second) and it's rather flimsy. And I couldn't be bothered to build a proper trigger for it so it fires when you slide a piece up on the back. And it's not tripod-mounted.

BUT IT WORKS.

Hell yes. That's hot.

Take a video.

Holy crap, I want to see a video of that baby in action.

NEWS FLASH: I looked again and I *may* have enough parts to make another 3 barrels. This will double the capacity and the rate of fire. I'll put them together tomorrow and take a video of it then because right now I'm going to see a movie.

Three more barrels would add loads the the coolness factor. Any idea of the rate of fire on that thing right now?

You know, I bet my ISD set has more than enough pieces to build a good minigun...

kyle90 the next "Jamie Hyneman" of Legos.

This would rox more with Megabricks.


Or not.

Maybe with knex though.

looks a bit rail-det-ish now

Okay so I got the other three barrels built and hooked on, but I was having some trouble with the return time of the escape mechanism not being fast enough to prevent it from firing two or three elastics at once so I had to add springs... crappy hack I know but it does do the trick. Of course now the motor gets bogged down because of the extra load now so I'm going to have to add another motor and/or change the gearing (which was pretty substandard to begin with). Also the extra weight is now too much for the motor tower so it's sagging and causing extra friction as well. So I've got my work cut out for me.

But let me just say, watching it spin up and unleash a stream of elastic bands at ~6 rounds per second is the most beautiful thing ever.

Kick. ***.

Yay, don't she look beautiful now.

Eh? I'm thinking Megabricks are too bulky for this sort of construction.

Okay I updated the gearing, completely rebuilt the structure that holds the spinny piece, and mounted it on a pan/tilt base.

Also I took a video of it in action, but the video sucks because it's from a cheap digital camera. You can't actually see the elastics that it fires; it's too dark and grainy, but at least you can watch it spinning I guess. I'll see about maybe getting some better video tomorrow.

Upload to youtube. I hate downloading wmvs.

Man, that sure does spin. Does it have a motor? And too bad we can't see the elastics -- how many can it carry?

[edit]
looked at the previous pics, and I can see it does have a motor. But my other question still stands.

EDIT: It works reliably with up to 6 elastics per barrel, but I've had it up to 10 per barrel before. Which sometimes messes up. So 36 - 60 I guess.

No way, definately Adam Savage.

Hell yeah, he's my hero.

I added a laser sight.

Coolness. How about a video where you're shooting figures or blocks or something? With something as cool as that it seems like a waste not to destroy something.

Ha ha. That's awesome. Fantastic work.

Atleast it's a green laser pointer so you can see it at night.

Also, what motors did you use? Ones from Lego?

I liked it more with three barrels, it sorta looked like the good ol' Rail Detonator then. =D

Okay bumped for a slightly better video.

Nice update!

I love the stream of rubber bands, that's fantastic!
