Scale Model of CEB Press
3d printed scale model of brick press- the same one we built our house with. 3D printed cylinders and washer solenoid valve + Arduino + pressure sensor + common 50 psi water pump. So the system runs not on high pressure hydraulics but 50 psi water. All the motion would be there - say as a 1/8 scale model or such. Everything works but just in miniature.
This system would allow for realistic modeling and code development. And, the model itself could be a toy or educational kit and product. It would be a great education toy combining mechanics, electronics, programming, hydraulics, and rapid prototyping.
This would allow school kids to do real prototyping for OSE purposes - and if the model is an exact scale model replica - that could help with fine-tuning the real design.
This links schools to science with a purpose and with industrial productivity.
