This all sounds extremely cool. What is the base espresso machine you are building this on top of? Do you have a blog where you document your process?

So many people ask this. The base machine is Rancilio Silvia, selected because it is relatively cheap, well made, simple, and has no electronics in it. It is a collection of AC switches, thermostats and other AC-powered components.

I don't care about making a blog. I do it for fun. Given choice I would prefer to spend the time doing some more cool projects.
