Default Handheld compressed air Cannon!

Thought it'd be a cool weekend project. Not much $$$ + bit of time and patience = all kinds of awesome!

Total cost was around $150 AUS (would be more like $15 in the states... or anywhere else for that matter)



The 'rifle' works on an extremely basic design. The entire rifle holds around 140psi (I wouldn't push it any further than that)
and the air is released via a 25mm solenoid valve. Shoots whatever is in there over 100m (300ft). It accepts a variety of different
barrel diameters, allowing for a range of various projectiles including but not limited to: oranges, paper rockets, water balloons,
anything you can fit in there

I just remembered we have some member here that built a potato gun with a laser on it, there were at least several here that built potato guns before, there is a thread or two on it and maybe in the gun thread too I don't remember.

For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.

I would like to see someone test one with both raw potatos and with baked potatos to test the difference in the effect.
