DiyPresso: DIY Espresso Machine

If you are passionate about Espresso, I really suggest to try Kamira (https://www.espressokamira.com/). It's very easy to make and maintain and you can have espresso at home like the one in the bar.

I am Italian, so coffee is almost a religion for us

Looks cool, but how does it actually differ in functionality from a regular mokka pot? Where is the pressure coming from?

The physical principle is the same as the moka pot, the water boil in the tank and the steam pass through coffee. The main difference is that in the moka the steam flows from down to up and in the kamira from up to down and it's not going to burn the coffee dust. I can assure that the coffee with kamira is exactly like the one that you can taste in a bar.
