Petitlu Very very interesting of how the internal flame front acts with obstacles, the type of spark gaps and the where it is placed in relation to the chamber. :) :) Is there any chance of getting a picture/schematic of your Flash And Transformer ignitor i am curious of how you achieve these better...

Very nice the second video looks great, especially the sparkler ignition :) This may sound silly but is there any-chance of getting some pics/video of your setup :), i have been interested in hybrid rockets ever since i saw this: [youtube]http://www.youtube.com/watch?v=lQ9Pg649MhE[/youtube] But i am...

This was an idea i had floating around but why not hook up the 12volt compressor to a 12 volt battery, then to a small accumulator such as a fire extinguisher, then that to your Airsoft Gun. Although you would need a switch (on the gun to turn the compressor on and off) and if noise is a problem the...

Pneumaticcannons, How do you inject the butane from the syringe to the PET bottle?

Sorry, this was kinda a dumb question , but i thought there might have been a fancy way on how to inject the butane.

Any chance of details on how the loading mechanism and magazine where made?

Awesome rifle you've got there

Thanks jazzman

They fire extinguisher you linked, is roughly $33 if you go down to you hardware store you can pick the same type up for $20.

My multishot gets about 10-15 (Good) shots, dropping about 4-5 psi per shot

I can upload mine if that would help you with designing yours

Is there any chance of a how to for that modded blow gun as i still don't understand how it works

Firstly WELCOME TO SPUDFILES :D Yes, the first (1) question is correct, all though you need to add a fill valve (air compressor) to the Pilot (TRIGGER) of you QEV such as a quick release fitting found on a air compressor (make sure is a male one so it can pilot). 2, A QEV cannot be pulsed once pilot...

Zeus, any chance of getting some of that 4.5mm Aluminium off you?
I have looked everywhere to find 4.5mm ID but still haven't found anything suitable yet.
N.S.W

Moonbogg, Thankyou for your concern but the diagrams and method outlined on this thread of how to place a fitting in and epoxy it in. Have NOT BEEN CARRIED OUT as a deduced that this was to hard for me to do at the current level of time. (Thanks JSR for the diagram and all your help :D :D :D ). Gipe...

Can i use this epoxypaint to coat the inside of the extinguisher to prevent rust?

This may sound dumb but, it's 30,000 volts but at a very low amperage so that if you jab someone it will not permanently disable them. :shock: I am a novice in the electronics field and am having trouble of how each component plays it's role in the circuit?? EDIT MR Crowley, Yes i know it's for a sp...

Nice rifle, any chance of those component pictures, you have inspired me to build my own version (if i can source the parts).

Looking forward to the video.


What's that tingling

another case of spud fever

What pressure can a QEV take , would this one do: http://www.ebay.com.au/itm/Pneumatic-3-4-Screw-Type-Air-Quick-Exhaust-Valve-/160639918364?pt=AU_Business_Industrial_Industrial_Supply_MRO&hash=item2566e2a11c#ht_2287wt_1139 Sorry but, i'm having a hard time on working out the dead space for my cannon...

This may sound like a dumb question but, i'm planning to build a 3/4 (20)mm barrel sealing piston valve air cannon using a rubber stopper as a piston. I've been down to my local hardware store ready to start the build but: the bunnings do not have any hose barbs as a sealing faces. What can i use in...
