It been almost one year since i did'nt posted in here because i founded another hobby: electronic

So i tought i little and i got a nice idea:

Why not make a paintball gun powered by butane combustion, but with the butane loaded by an sprinkler valve wich would be connected with the igniter ( a 1.5 volts continuous bb-q sparqer) and a computer electrical fan via an printed circuit board.

A timming circuit (555 ic)will sequence all that stuff.

1st: you reload with the bolt action (the paintball will get stuck with an o-ring )

2st: you press the trigger(the sprinkler valve let the butane fill the chamber and the fan lights on)

3rd: 2 sec after the 2st, the sparqer lights on.

4rd: ka-boom, enemy headshoted


If there is a butane over fill, you will be able to unfill it by pressing a button, wich will light the fan.

What do you think? Plz reply to my post.

A sprinkler valve would be horribly oversized for fuelling unless you are going for a combustion chamber the size of a wardrobe.

A or maybe a pair of small directly operated solenoid valves would be more like it.

Aside from the valve choice if you can automate it, go for it. I don't think I've seen anyone get round to actually doing anything major with a 555 chip no matter how often it's mentioned so theres still an opening for being the first round here.

Why a sprinkler valve be overzized?

I'l explain furter what i explained.

liquid butane bottle-pressure regulator-sprinkler valve-combustion chamber-cannon.

After the sprinkler valve, there will be a cap with an 1/32 inch hole to dont make the paintball pop out.

I FORGOT TO ASK MY PRINCIPAL QUESTION: WILL THE SPRINKLER VALVE STANDE THE HEAT OF THE COMBUSTION TROUGH THE 1/32 HOLE?

Still a sprinkler valve is unneeded. For something like a paintball gun you only would need a solenoid valve. Anything more would just be overkill.
