Instructions For Rolling Your Own Railgun

[HardOCP News]

Ever wanted to build your very own railgun? Well, now you can thanks to this guy and his 5.6kJ roll-your-own-railgun instructions.

He could have helped page load times, by resizing the images before uploading them, rather than get his html code to do it. For instance a few of them i looked at are 3648x2736.......yet scalled to 800x600

the ones from 16ft or so don't look as though they hit anything in the video...

 

[PyroHoltz]

Looks surprisingly similar.

So are all the sparks errupting fromt he gun normal? Neat idea though.

Yeah, they slowly tear up as they are shot. A gauss gun is another kind of magnetic gun that doesn't but they aren't as powerful.

I'm kinda confused. Aluminum projectiles? They wouldn't be an optimum material to influence with magnetic fields. I suspect that most of the kinetic energy is a result of the pressurized air. Sounds like an air rifle that makes pretty sparks.

From the front page all you can see is "Instructions for rolling your own..."

Got me all exicited.

 

[Sherk]

Yeah, I was thinking the same thing. Doobies on [H]? WTF?

 

[Elledan]

"Rolling your own..." har-har~ how funny

I still prefer coilguns over railguns. More efficient, works with more projectiles and tends to not destroy the gun (rails) a bit (or completely) with every shot due to arcing. Plus figuring out the best timing mechanism(s) is a lot of fun

bingo!
he has invented a pnuematic, high velocity, spot welder. No timers involved.

hold a large magnet near a spinning aluminum disk and you'll see why he uses aluminum.

compressed air is cheating!!!1one!!

when I was 16 or so I made a coil gun out of a few old school mechanical answering machines with coils. stuck a nail in it, temporarily put 110V on it, and it would stick a nail in the wall.

for some reason I thought this was explain how to built your own gravity gun. G. Ravi -ty

i am as stupid as you are. i thought the same thing.

 

[Enduring_Warrior]

wouldn't load.

Is this as effective against cats as crossbows?

 

[jeremyshaw]

Not as effective as rifles on people... like those who kill cats.

What else are cats used for other than target practice?

Hey! I'm a cat too!
