I am looking to build a potato canon (spud gun) as a summer project… Unfortunately, using combustion is illegal in my state, and my parents aren’t too happy about combustion anyway. I am probably going to end up building a pneumatic cannon. I am going to use copper for most of it (so the darn thing doesn’t explode), but I need a good solenoid between my reservoir and barrel.
I know I could just use a ball valve, but I like mixing in electricity with my projects
What solenoid would you recommend? I would imaging a large diameter, fast action valve is best, but I don’t know of any good stores to buy those at. Power isn’t really an issue, as I could attach as many 9v as I want to this thing.
