Well, I finnaly got my computer to not fork up when I use the card reader Here is my baby pneu and a shot of the primary ammo.
The human lungs average 5 psi possible output, this can propell a blowgun dart around 300fps, I can pump this in excess of 95psi except mt barrel shoots off at about 70-75 psi. I can put a dart through a 2x4 and have some sticking out of both sides.

Whoever appeals to the law against his fellow man is either a fool or a coward.
Whoever cannot take care of themself without that law is both.
For a wounded man shall say to his assailant,
'If I live, I will kill you. If I die, You are forgiven.'
Such is the rule of honor.
