Alright, The wood, nuts, bolts, screw, L brackets, plastic, plexi-glass, wire, air compressor, duct work reducer (to create funnel), and pail can all be bought at a hardware store outlet. (I had most of those all on hand)
Everything else
Pneumatic cylinder -crusher 25$
loading cylinder 30$
Solenoids 20$
6mm quick connect fittings 15$ you may need to order a converter or adapter to fit the crushing cylinder. I think its 1/4" fittings, so you could order those too but be sure to check
6mm Pneumatic hose 12$
6mm T splitter 6$
Air Pressure Regulator 10$ use to regulate the air to the loading piston as it runs at a lower psi/ can be slowed down some as well.
Shut off valve 6$
Quick connect to airline 6$ What you need may be different. Depending on your set up.
Arduino Uno 15$
12V Power supply 7$
12V to 9V 6$
158$ + construction materials that shouldn't cost more than 50$
Note: Some of this may be found else where for cheaper, but at least you know what you are looking for. Also I rounded everything up.
Let me know if this helps at all.
Edit: Its also helpful to have someone who can weld, so that cost has to be factored in as well. I traded work for work.
Is shop air available? As far as I know, there's very little water in shop air. I'd try putting a small regulator like this on the outside of the box, with a small bulkhead (Say 4mm or 5mm) going through the wall. Regulate the downstream pressure to provide air flow, and a check bulkhead/check-valve on the box elsewhere to provide means of escape but prevent anything from coming in?
Just spitballing here.
