I'm doing an Arduino hardware project, and would really appreciate some feedback from this forum. Central to the project is a rectangular cylinder which will be moved by a solenoid controlled by an Arduino. I have attached a sketch of the rectangular cylinder below. The piston in the cylinder will move up and down as shown on the sketch.
Figure 1 shows the rectangular cylindrical chamber. Figure 2 shows the piston which will move up and down inside the cylinder. Figure 3 shows the cylinder from the side.
The cylinder must be quite strong and light, and work in temperatures from -20C to 30C.
I'm wondering if it is possible to buy such a cylinder somewhere? If not, what is the best way to get someone to make a prototype of such a piston?
Thanks for any help you may be able to provide!
