The rest of the session followed the usual formula with the kids working through the various projects. Some are a little further on that others, but everyone is making great progress. I'm increasingly finding that I'm spending my time explaining more complicated aspects of Python and Linux than answering the basic questions ("which one is the HDMI cable again?") I was for the first few weeks.
One chap who has been experimenting with the buzzer using Python discovered that at a certain frequency it makes a screeching, ticking sound that he thought sounded like a bomb about to explode. He decided to hide behind his chair and, apparently without any rehearsal, most of the others followed suit!
