What size of a mini pump are you talking about?

about the same size of the cannon. I am pretty sure it can be done cheaply and effectively..
And jsr, the fridge pump is sweet... it jets to 400 psi like its nothing. in this mini, I get to 400 psi in about 5 seconds... Of course my larger projects take more time, but its managable.

If
this is anything to go by, you can make one quite easily and with a bit of effort (more in terms of time than energy) reach high pressures to get the most out of your pengun. Methinks I'll have to build another one when I get home, the design still has a lot of potential in terms of performance.

All these penguns. I might just have to start tackling people who walk up to me with a shiny object in their breast pocket...

No.
If you do, please don't discuss it on this forum.

For something which I threw together quickly in a couple of days for the competition, it has generated quite a following
If nothing else, it seems more and more people are realising that there are alternative and workable materials to PVC when it comes to making spudguns, and it also challenges the stereotypical image of a spudgun as a bulky low pressure device. All good in my book

Yeah, but you still gotta give a hulking PVC contraption emptying a magazine of tennis-balls in 'burst-fire' at 170 PSI props, though.

Naturally, by no means should traditional PVC monsters be replaced, but it's nice to see them complemented by new developments, it any field
this is a good slogan

haha.. after playing around with these little shooters ( I bet I could go way smaller, but it wouldnt shoot worth a damn), my next plans are to build a massive pvc monster. I want it to show why we call them potato CANNONS.
I enjoy showing my creations to the guys I work with (we frame homes) and I want the next one to make them go "what the hell dude? you are insane"

Of course size *does* matter, a massive cannon will always impress, regardless of how crude and unsophisticated it is. Beware of those who suggest you might be compensating for something though

Hey, nice pengun. I should do something like this... I keep telling myself I will, but never do it. Ugh, if only I were better at making commitments.

try it, you may be surprised at how quick and painless it is to make it.

okay okay ill be the idiot to ask how does piloting it with a shrader valve work because when u pumper up and take off ur filling end it will realese a small amount of air thus actuating the piston and so you wouldnt be able to fire it with pressing in the shrader valve

You can either remove the pump
really quickly, or do what I did with my shock pump and mod it in such a manner that it doesn't actually open the valve stem but air flows through by wirtue of pressure difference alone.
