As a rule, good Italian espresso machines are no cheap deals. My design challenge therefore was to facilitate the espresso machine production and to create an inexpensive, low-complex DIY espresso machine. Most of the parts are either standard components from the hardware store or spare parts of traditional espresso machines. Mainly, it was important to me to think and publish the espresso machine as an open source project under a Creative Common License. Everybody, who is interested in my work can use the manual to improve or just to build the espresso machine themselves.
