*real pics*Gauss (electromagnetic) pb gun

So, I have developed what is probably the first Gaussian Paintball gun.  It is in the early stages, but is coming along quite nicely.  I currently have a mess of wires, two circuit boards I made, a switch assembly, a barrel, and a capacitor bank.  It works, its just in a big mess right now.

This is basically how it works:

1. Trigger is pulled, power is sent to the timing circuit, triggering it; the bank of 40 capacitors is discharged and charges the shooting coil.
2. The shooting coil, with 10,000 volts flowing through it creates a great magnetic field.
3. The magnetic field pulls the magnetic bolt towards it, with the ball in front of the bolt.
4. The bolt is stopped by the stopper in the rear, the ball continues to shoot out of the barrel.
5. The timing circuit discharges a bank of 10 capacitors, 2,500 volts, charging the cocking coil, pulling the bolt rearward until it hits the stopper.
6. Ball is pushed up in front of the bolt.
7. Capacitors are recharged.
   

This is basically the simplified process.  It is greatly efficient because it takes 10-15 seconds for the capacitors to recharge (using 2 9v batteries).  Keep in mind this is a high voltage device, 10,000 volts (although low amps) isn't something to play with, I have shocked myself thrice with it, it didn't burn me or hurt me, just a very nasty bite.

I hope to eventually make this into a gun i could take with me to the field, it would be a great new concept.  Here is a diagram of what an assembled (and decluttered) gun will look like.  I can post pictures of my working one later tonight if enough people want it.

Let me label the parts.

• Green and black blocks are the coils, the two blocks in the front are actually connected (it is a cylinder), same goes for the back.
• The brown thing is the bolt.
• The ovals on top of the gun are the capacitors
• Yellow semicircle is the "charged" light.

Right, thats just right now.  I will eventually attempt to make it more efficient (lighter bolt, meaning it needs less power), and maybe even add a second capacitor bank and second charging board, meaning I will be able to shoot 2 balls every 10 seconds :).

The thing isn't meant to be perfect, how do you think the first air pb gun ever made worked?  (I'm talking first, not first production).

Also, I forgot to mention that a big advantage of it is that it makes no noise except for the bolt moving in the barrel.

Yea, I thought about that.  I figured someone would have thought about making this type of gun some time before, but I doubt it would sell well.  Gauss and Coil guns are known for being atrociously inefficient, and this type of thing will burn through 2 9vs in probably 500 balls.  I have been thinking about doing the poor man's patent when I draw an actual design.

EDIT:  Also, what parent will let their kids have something that if they screw around with, could put 10,000 volts though them.  I would assume a "Danger, High Voltage" sign would have to be put on it, and since most parents don't know much about electricity they will avoid it.

Pretty sick, how far would it shoot though withough breaking the ball from the shock of the bolt?

and how many amps does it take to kill you? like 1.9 or something?

100 milliamps will stop your heart.

100 milliamps across the heart will kill you, I should say.

black = hot, white = neutral in my case, sry, the only time you put power to white is when running a switch leg from the light to the switch when the feed is in the light or 3 way/4way or something similar, and in that case the wire must be recolored

wire a house and tell the inspector you used black as the neutral

So here is a pic I took of my actual device:

I want to see it working.

So is the bolt basically in the barrel?

OMG protein stain on the sheet. EWWWWWWWWWWWWWW!!!!
