Introduction: H.S.P.L (High Speed Projectile Launcher) PROTOTYPE Knex

Picture of H.S.P.L (High Speed Projectile Launcher) PROTOTYPE Knex

This is my H.S.P.L it is made with knex and lego mindstorms it is a form of minigun and fires 8 round in .5-1.5 seconds the lego isn't needed but makes it easier. SHOULD I POST IT!!!!

hey, you can use a dril, just treat the rod like a bit and trhere you go, a VERY fast gatling gun. probobly shoot all shots in 2 seconds though

Try 1/4 second. The motor in this slideshow can drive that to fire all the shots in under a second and a half. That type of motor can also move about ten pounds rolling (tried at camp, made a freaking tank with three NXT kits) at a decent speed.

ive just thought of the best way to shoot someone in a knex war which is... get a gattling gun(a knex one well duh), make as many i am canadains war bombs as the amount of barrels in the gattling gun atach each bomb to a rod and load them in to the barrel and shoot away (that would be cool and i am doing it

Not particularly intelligent unless the objective of the game is to injure the other players as much as possible.

hmm... one wrong move and it'll blow up in her face! be careful mate!

no, you don't need to post it.

Bad Oompa Loompa! That looks pretty cool

You seriously shouldn't have said that. Oompa is a PRO at knex.

Thanks but I wouldn't consider myself that good. Perhaps if I had more knex I could be a little more creative.

Hey, i'm stickin' up for ya! Lolz ... I FINISHED MY MINIGUN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! shame it doesn't fire nothin' though.

Picture please?

Incoming dude... "BEEP - Upload complete" And, this is a portable full size model. four barells, with 2 supports, on top + below. It uses the cyber k'nex dual motar, cos my single is 'stuffed full of battery acid' shall we say... lol. It gets pretty fast, once it gets going. i rlly nead some sorta RBG system on this to make it shoot stuff...

Looks really cool besides the fact that it's so hollow.

I thought that too... maybe some paneling could sort that out.

That could work, nut then would this get rid of the gun's curving shape?

mmm... but... if i changes the blue rods on the ends to green rod + orange connector + white rod, it fits perfectly... if i did that i could plate it... i'll see what i can do :-D

Hmm... i think i'll go for it... i'll make it shoot stuff too!


:-S Unexpected problem... DAMN BROTHER!!!!!!!!

F41LUR3 lol

Damn right!


*pop squirts out nose*

We already have a lot of these posted.

I just meant that it isn't nice to tell people that they cant post ssomething.

They can, but there's no point.

Very cool idea using the lego mindstorm motor

Could use a gear shift mechanish like my new minigun... (PICS ARE ABOVE SOMEWHERE)

AzraelUK (author)2008-12-29

Definitely post it! It looks like a great project, and I'd like to see how you use the Mindstorms along with the K'NEX.
