What do you get if you cross a Raspberry Pi with a Breville 820ES Espresso machine? A Raspberry Latte!
There has been a long standing symbiotic relationship between engineers and coffee!! So it only seems natural that a candidate project for my espresso machine is a Raspberry Pi brain transplant. Of course I'll keep the blog on the coffee machine, it seems appropriate!
I see the project running something like this.
1. Acquire the circuit diagram and study to understand issues such aspower supplies and interfaces.
2. Reverse engineer the control processes currently operating on the espresso machine.
3. Design a suitable interface.
4. Implement WiFi on the Raspberry Pi to avoid running cat5 to the coffee machine.
5. Develop a suitable coffee machine application.
6. Develop a suitable web based interactive application
Some issues I see.
1. Failure mode safety management (circuit design).
2. Electrical isolation between the Raspberry Pi and the high voltage electrical devices.
3. Physical space and form factor.
4. Being without coffee during key development steps, ie keeping the coffee flowing during modifications.
