Raspi calendar - HW-SW

 OK, this is my set up for a calendar display using a Raspberry Pi.

Is quite a while that I wanted to have somewhere a calendar display and was considering different solutions, then one weekend I decided to do something about.

The goal is to have somewhere (kitchen maybe) a monitor showing the Google calendars of the family.
Here some notes.
I'm assuming who is reading this article knows how to set up a Linux system, I'll not describe in details many operations.
