go to wall mart and ask for old disposiable cameras, get the caps out of them

i attempted to build a mini railgun

i might post pics later

but when i build it i was a tardo with electricty and didnt know the circut would not hold so i overloaded it but it still looks cool

someday i might rebuild it right someday now that i understand how it works, but lateley i have no ambition

i made a rail gun designed to shot aluminum foil but the capacitors i used just instantly vaporized it... still a cool effect :roll:

Did the foil move anywhere when it vaporized? I heard that sometimes it flies forward, making it look like a plasma gun of some sort.

By the way, (iPaintball) I got my caps out of computer power supplies, so the company I got them from is technically is who ever made the PSU.

Edit: Just found an interesting picture vv

In their most basic form, these are relatively smal and only need one capacitor, or a bank of small ones.

But i'l probably get stuck into this next weekend, because I'll be using this whole week for a 4000 word report for school: on combustion vs pneumatic spudcannons


I wish I had to do that for school! I could probably write a book on it! I cannot WAIT to go to college!


Yeah, I go to an IB (International Baccalaureat) school, and get given a year to do a personal project, which is basically anything, but then a 4000 word write up follows.
I just made the best of a bad situation, choosing to do a comprehensive analysis based on the comparisons of pneumatic and combustion projectile launchers. In fact, that was the reason I joined this site...

I made my first one out of the parts from a toaster;
Image
Fires a BB at about 5 fps and a piece of nail at about 10 fps. Heck, I could probably have fired the BB farther if I had just "toasted" it. (Joannaardway is right, a round projectile is absolutely the worst possible shape for a coil gun.) Linky with details.

Here was my second, based on a disposable camera. This one uses a PC to record the muzzle velocity as well as the discharge time of the capacitors. Kind of lost interest before I ever made a halfway decent coil.

Like singularity said, the preformance of a particular gun+ammo is critically dependent on the starting point of the ammo. Image
This was for firing BBs. A change of just 1mm (~1/25") dropped the velocity by ~5x.

@jimmy101

Is that it fully assembled? and why do the annotations have question marks?
I'm sorry for the interrogation, but all I see is the components, and not the product.

Did you forget to finish that sentence? :lol:

Yes, yes I did.
And I've also forgotten how I meant to finish it, which puts me in the privelaged position of being able to introduce a "How did Jo intend to finish that sentence?" competition.

The options are below.
a) because it's 'different'.
b) because I can.
c) ...get down! Ninjas! *leaps into air, and claws slide out from between knuckles with "shing!" noise.*
d) Or something else?

Do you actually call him that in 'real life' or is it an internet thing.....

No, it's not just an internet thing. One of David's many nicknames in reality, so it gets used elsewhere.
