Instructables user Urant decided to create a pocket-sized espresso machine that could be built using simple tools and parts from a local home-improvement store.

Design constraints are some of the most important points of any product design; they tell us what the limits are. The tighter the constraints, the more limited the design, and we have to be more creative to be able to meet them.
On this project, I set the following ones.
1- The product had to fit in the pocket of my jeans.
2- The product had to be made out with common, cheap and easily obtainable materials from any home improvement store or corner hardware store.

4- The product had to be self-contained.
5- The budget was maximum 30 dollars.
