sorry for linking to other sites btw, but i think this'll help the OP.

wouldn't salvaging a remote controlled RC and rewire the motors to a relay and replace the stungun's button with the relay's terminals be possible as well? and remember those RF stickers used to track shop items? you could pretty much use that as the transmitter fitted inside the ammo and a regular ...

I call it "FlexPiston", since the piston is hollow and pressure can sip through the holes, the flexible membrane would bend towards the tube and sealing it.. 10 bar would probably burst teh rubber diaphragm valve that's why sprinkler valves have big washers to take the pressure. also the pressure w...

or you could just add a gear to increase the torque.

what? you only need like 10revolution per second(600rpm) usually motors have like 20-35revolutions per second(1200-2100rpm)...

true enough, but its the easiest to create and not much mod. got to disagree with the holding pressure tho, it depends on the piston's seals and that depends on who made it. Edit: i withdraw my statement, there is a way to enhance the piston valve's pressure flow rate, using this theoretical design:...

why not make a piston-valve driven by a motor? ever seen a steam-train?

Edit: or better yet, if you know how the jackhammer works you could use that instead to drive the piston valve =D

^ nice catch, i'll keep it in mind.

When I say high power, I mean it. I put one through my sheet rock and had to tell my parents I put a tack in the wall to hang a poster instead of tape. And my trigger failed for it and my brother walked past the barrel just as it failed, and it shot him in the back... No pictures, I can't afford to...

idk, this thread has became a fun feast instead of the usual theories thread. well not really a cons because you guys just kept giving me more ideas...

TL:DR the real topic is about recreating the movie's mouse-fart silencer sounds.

its a combustion spud, thats why i'm attaching it on the end-barrel. advantage of putting the recreational kit to the end-barrel is that the projectile already has momentum and almost out of the barrel so any loss in pressure would hardly affect the projectle. well if it was compressed air then it'l...

^ YES thats the point, me want a sniper that goes "pew pew pew" or a pistol and make it look like an alien blaster XD well without me screaming the "pew pew pew" nor using any loud speakers. btw, can i ask you guys something? what happens to the expanding gases after the projectile leaves the barrel...

its not really that complex, its just you added an internal heating element, just pouring boiling water before closing the end caps could do the trick as well. how hard do you think would it be to put ice cubes in a Gatorade bottle? its the same concept but with added wires in it. seams much easier...

you must be drunk, well i'm aiming for a legit goal while you're making fun of it, well it works for me because you gave me another idea XD so long as we both enjoy this argument then i think its fine.

oh and, thats some cute hamster, sadly it has some effing poo.

does the underlined quotes seem to be pointing to making it silent? i'm trying to make it scream man instead of a bang... ever wonder how to replicate those TV show's silenced pistol that sounds like a mouse-fart? this is the plan, well not exactly a silencer ... anyway this is only theoretical (for...

so what are you trying to say? its impossible to replicate or possible? i'm trying to find a way to replicate the mouse-fart sound... can't you get what i mean?

ok ok, now i seem to get what you're thinking... how about rephrasing it to recreating instead of replicating? more meaningful to you?
