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.

You may be able to use the DC motor assembly that drives the laser in CD players. Should be a fairly cheap and common commodity. I'm not sure how much torque you need, it may barely work or not work.

Pneumatics or hydraulics are the strongest compact actuators at that scale. Like this:

Hydraulic fluid has the benefit of easily controlled speed, where pneumatics can be a bit more touchy. You can control those using compact quiet pumps and miniature actuators like Festo solenoids. Sprinkler solenoids are a very cheap DIY actuator.

I've had no luck finding PTFE tube aside from the common sizes!

However, I have found press fit connectors that let you step down from a 6mm OD tube to a 4mm OD.
You could likely use a couple to step between the two sizes of tubing. I don't know that this would work for your purposes, but it may be worth a try!

Here are some on Amazon

You can also find them on ebay for under $1 (USD) a piece.

Try searching for "4mm 6mm pneumatic push fitting."
