There are times when I could really go a small coffee. As a matter of fact I could go one right now. Coffee shops aren’t hard to come by, but for the ultimate in portability, you need something a little more portable, like this pocket sized hand made espresso machine.
This particular pocket sized machine is the brainchild of Instructables user urant, and is mostly copper, although it’s stated in the instructions that medical advice was sought to check that it wouldn’t create a poison brew. Total cost of parts was less than $US30, which is impressive all in itself. [Instructables]
