Crate PopUp

The pop-up crate project involves a pneumatic cylinder (bicycle pump or professional cylinder) to operate a head to pop-up from inside a crate.  This is the easy project to work on for all of those beginners out there. See a video of this project in action.


    1. The crate for this project can be made out of wood and screws or you can use a ready made crate as well. The size of the crate is 1 X 1 X 2 feet this gives you a rectangle box that is two feet tall. I use 1 X 3 inch wood to construct this crate. 

    2. Metal strapping to attach bicycle pump to bottom of crate.

    3. Bicycle pump or a one way cylinder.  The bicycle pump should have around a 15 inch stroke. Stroke is the length of the rod that comes out of the bicycle pump or cylinder.

    4. Pipe fittings for this project will be needed for the bicycle pump and the output to your air compressor. Six barb fittings and one T- barb will be used all the same sizes.  The sizes will depend on what size tubing you will use, in this case we are using 1/4 inch size tubing so you need barbs that fit 1/4 size inch tubing.

    5. You will need a valve or use a flow control valve to adjust the speed of the cylinder. The valve should have the same size fittings as all of your pipe fittings to make it easier.

    6. Some ¼ dia. pipe.  You can use the same white color pipe as they use for refrigerator ice makers.

    7. A two way normally closed solenoid valve that can handle 30psi.  My links page has a few companies where to buy solenoid valves from.

    8. A mask or a head of some kind to attach to the top of the cylinder.  The head needs to be able to fit inside the crate.
