Acquire the circuit diagram and study to understand issues such aspower supplies and interfaces.<br \/>\n2. Reverse engineer the control processes currently operating on the espresso machine.<br \/>\n3. Design a suitable interface.<br \/>\n4.

Electrical isolation between the Raspberry Pi and the high voltage electrical devices.<br \/>\n3. Physical space and form factor.<br \/>\n4.
