Hey love the machine! So curious about it.

I've built a couple cocktail mixer machines for personal usage in the past and always wanted to build an espresso machine. My main fear was dealing with almost boiling water and pressure, that kinda scared me a bit. Do you have any tips, links or just fun stories about developing machines like that that you could share? :D

There are lots of people who have "Arduinoed" their coffee machines, especially the Rancilio Silvia, which is an ugly-but-good-value machine, which can be PIDed and hotwired. That's a good place to start.
