Making good home espresso is possible, but the machines tend to cost a small fortune. ZPM Espresso, a startup in Atlanta, is hoping to change that with its open-source espresso machine.
If the company succeeds, it could have a nice market for itself, as the espresso and specialty coffee market have been growing quickly around the world. (Can you tell based on how many Starbucks and Peet’s Coffee places there are?).
The founders like drinking espresso and they took apart a bunch of old machines to see how it’s done. They figured out how to make a machine for less money, but including important features such as PID controls, custom temperature, pressure profiles, and open source hardware and software using Arduino, a kind of microcontroller. The microcontroller governs the behavior of the thermoblock and the pump, rather than relying upon mechanical controls. That allows the data to be analyzed, saved, and shared.
