electronic paintball design

Unread postAuthor: Demon » Sun Mar 01, 2009 8:28 am

Ok, i made a plan of my electronic paintball project.

I would need your advice if it will work or any error in the design or things that i could fix.

Here is how it works:

1st: You reload with the bolt action mechanism( maybe not if i found a electrical piston to reload automaticly)


2nd: You press the trigger, wich activate a electronic system

3rd: After the gun is triggered, the solenoid valve opens and let the butane fill the chamber for approx 1-2 secs(i will have to make a lot of trial and error for this one)

4rt: after the filling is complete, an sparqer lights on and the paintbal is fired.

So its 1 shot at each 4 seconds.



For the one who will say that a sprinkler valve is overkill, i am obligated to do like that. If i get a 3/8 inch solenoid or something like that, the flow will make pop out the paintball out of the barrel. with the 1 inch one, i can reduce the flow up to 1/32.
If you have a better solution, plz tell me


I would really need reply's and your advice, because this will cost me i guess 100$, maybe more.

Do you think they will let me play in paintballs field with that thing?

No there's a tippmann c3 that uses combustion that isn't allowed on fields.But do get a definitive answer you should ask your field owner.

Looks like a solid plan, I've just been wondering:

How does the chamber get vented/refilled with air after each shot?

And don't you think 1 shot every 4 seconds would kind of put you at a disadvantage on a paintball field where people are walking around with guns shooting 24 balls/second?

There is a computer fan wich is also connectd to the prnted circuit board and that is activated before and after shooting.


Yea, it wont be a good idea to go on paintball felds, i will shoot my friends with it( they have airsoft)

Do you think there is an pc fan that can fit in a 2 inch pvc pipe?

There was a gun posted a while ago that had a pre mixed fuel tank eliminating the need for venting. Maybe you should go for that?

You can tell how awesome a cannon is by the pressure used.

Not really sticky_tape because it will reduce of alot the butane capacity then if i was using liquid butane bottles.

Do you think some pc fans fits in a 2inch chamber?

Do you think the sprinkler valve is safe from the combustion heat?

I wouldn't have thought that any commercial paintball site will allow you to use a homemade combustion gun....

It will not be allowed on the field.
Even the not-homemade tipmann c3 isnt allowed on most fields.

Sprinkler valves can NOT withstand alot of heat.
Metal construction is a must.

And last but not least:
Okay, so you will vent using a fan. But will you use a non-return valve or something like that?

I think, if i make this thing, il have to make a backpack with butane and oxygen bottles to dont hassle with venting.

Or else i will have to put a ball valve.

Agree on the oxygen bottle.
I would indeed do it that way.
But oxygen comes with danger so be careful.
And ill just say it again: metal construction.
