discovered another cool website.

[Benny]

found a site youse mite like, i just finnished the capacitor bank, it sounds like a .22 when its shorted.

[Rambo]

It gives me Sorry, this GeoCities site is currently unavailable.

[Benny]

sorry, try again in like 5 minutes, it done the temporeroly univalible thing for me too.

[)DEMON(]

yes me aswell (message is too short)

[Clandest1n3]

yep did it for me to

[CS]

Alright, alright we got it. It doesnt work... I dont think it takes 4 people to say this for us to understand it does not work.

[Benny]

it wasnt doing that yesterday.

[taz22]

it works for me it looks coowl. buth don't get it how it works. does it shoot a beam of light ore something?

thnx grts

[Benny]

well , when you put the high voltage pulse through the rails the foil vaporises into plasma, and creates a very strong magnetic field, shooting the plasma out.

[Rambo]

How do you know wich way the foil will go?Do you think it is possible with 10v 650 000mf?

[FiveseveN]

@Rambo: The magnetic field is generated following the cork rule (if I remember from years ago in Physics) you'll figure it out if you read PpowerLabs' articles on them: http://www.powerlabs.org/railgun.htm

@Benny: If the foil vaporises, the magnetic field will have nothing to pull. Plus, this is a KE (kinetic energy) gun. Energy=mass*speed. How much mass do you think a molecule of aluminium has? Hint: by far not enough to be used as a projectile unless it has speeds aproaching that of light.
As a side-note: Particles (albeit heavier than Al) have been accelerated to energies equal to a bullet. Yet these particle accelerators are as big as a city block and use just as much power. What I'm trying to show you is that a plasma gun like the one Benny is talking about would be REALLY, but I mean REALLY impractical. Railguns shoot solid proijectiles, period.

thats pretty cool

[saladtossser]

ok i will put this thing here cuz i need to look at it and it keeps running outta bandwidth

http://72.14.203.104/search?sourceid=na ... railgu.htm

google cache is the best thing that has ever happened

with this plasma at least burn skin or ignite matches?

[FiveseveN]

Yes, but only for 1/3 of a second and at limited range (perhaps 3 feet for the Powerlabs railgun). So having a quarter-ton 5-foot-long railgun to ignite matches 3 feet away is pretty stupid. You could do the same with 3 grams of gunpowder.

The site talked about graphite slugs. Sounds to me like industrial motor brushes (solid graphite ones) would make a great projectile. Of course, you'd need a pretty big railgun.

this rail gun he made is just to demonstrate how it works for a cheap price, it is really mad
