Electro Powered paintball gun?

SUPER CHARGE THE WARP AND PUT A BARREL ON THE HOSE

[John Molloy]

The problem with all the ideas put forward so far is they rely on instant acceleration of the ball, every fly wheel or belt idea suffers from this problem. But the rail gun idea could (thats COULD) work problems are acceleraring the ball and power. make the balls slightly magnetic and your barrel would be HEAVY and long with hundreds of electro magnets the power supply would weigh about the same as a 12v truck battery which kinda defeats the object.

What sounds more logical to me is to change the air supply by adding an electric air compressor, but again it would have to run at such a high RPM, it would not be feasable. I have heard of some pneumatic power tools (nail guns) that do not require a compressor. They run off of a cell that contains a combustible gas capable of creating enough PSI to operate the nailer. Maybe in the next decade we will see combustable fuels used as a propellant. I can see it now... tiny model airplane engines on the side of my micromag. Where would I run the exhaust? Haha

why does it seem that so many people want a railgun paintball gun. the only benefit i could see to one is that, since it would be so big, you could sit in the car it was mounted on and roll the windows up, and not get shot!

Here is some info to get you started

Here's a couple of websites that might help you get started on the Rail Gun Idea.

I'd like to see some idea's that come up here on the AO.

Have any of you guy's looked at airsoft guns? just took one apart and the use a high power spring and electric motor to pump air under pressure to shoot the BB now I know that the pressure to fire a 0.2 gram BB any distance is a bit differant than required to shoot a paintball that is significantly larger and heavier, but the same principle(in principle ) could be applied (large motor huge spring huge air resevoir)

Question does anyone actually know how much pressure must be applied to the paintball to shoot it at 300fps?

With the size of the spring known and motor known then all that is left would be the power source, and we come right back (at the moment) to the same problem we have had from the start. The battery would be large, maybe not as large as a 1.9 l bottle (88cu) and with NiMH technology it would be robust.

The way it works is like this, the paintball falls in the breech, you pull the trigger, the motor pushes the piston back on the spring, then releases causing the piston to preasureize the air infront of it which hits the paintball.
The drawing is very rough but it gets the point accross.

Just to note a paintball weighs 12x as much as an airsoft bb, and its diameter is 30x larger.

to get a paintball to shoot at 300fps you need about 100psi, I dont know how much volume. But this would be big

[John Molloy]

Yeah thats right but like I said the Piston would be huge the air chamber would be huge the spring would be very strong (so far all do-able) and the motor to run it would be huge, last but not least the battery isn't going to be small either. The whole package may end up weighing less than a Cocker with bottle but it'll be bulky and it may well be fragile.

Tried that a couple of years ago Hitech. It sounded good, but I wasted a lot of money and paint.

wow my deep blue threads last a long time it seems anyway it seems doable but with todays technology it would be large and implausible. but worth a try :)

You actually tried to make one? Did you have something big enough to fire the paintball at a reasonable FPS or did you give up trying to find something big enough? When I said big I probably should have said HUGE!

rail gun

it( the paint) wouldent have to be magnetic, just conductive to eletcity. See site www.railgun.org
fun eh? also you could use a hig cappacty lithum ion battery( laptop type) on a body harness kind of ike a remote harness. Also i have an Idea for a possible e-conversion to thefront block to an auto cocker. replace the block with a high power solniod (25v+), put a roler switch in behind the sear( like when you intell a warp in a non electro), and hook it all to a EPERAM timeing chip in the handel. finish it off with a harrnesed laptop battery to power? (AM i crazy?)

I stumbled on this thread, and thought of my roommate. He's got a 43k RPM motor that runs on 7.2Volts for an RC Car. He's also a bit smarter than me.
I'm probably stating the bleeding obvious, but just in case;
Basically, we figured out the following, and even then, alot of this is my thinking, which COULD be wrong...:
-7.2 Volt power source. 6 rechargable cells, could be easily displaced.
-If 2 rollers were used, they would require less rpm than a single roller, plus the force displacement is more even, reducing the chance for tearing even more.
-We'd get a theoretical run time of around 10 minutes of constant operation.

I have an idea for the operation mechanism as well...
think of this -- When the trigger is pulled back, a hall sensor type dealie (like the one in the e-mag) is triggered to rev up the motor... and once the trigger is pulled all the way back, a trap door at the top would be open to let a ball drop in... The issue would be to keep it from keeping the trap door open the whole time... Although if it was left open, it does raise the interesting concept of a gun where you've essentially got a load time that is limited only by the speed of the loader, as opposed to having to wait for the bolt to cycle.

The Ideal trigger type for this freak of nature would be an Autococker Style Sliding Trigger, the first part start the Electronics... And as it is pulled back the trap door would open up to the door.

Again, I could be all wrong... But this sounds like a possible approach.
