That'll teach me to go away for a weekend. It seems my previous post "Automatic Raspberry Pi board revision detection: model A, B1 and B2" was surprisingly popular. It was picked up by several important Raspberry Pi web sites and led to a significant spike in visitors. If you are someone who found their way here because of that post, welcome! I hope you find something of interest.
Traffic seems to have eased off now, so I hope to get back to my usual mix of Raspberry Pi hardware projects and reviews together with a journal of work on my own "bare metal" operating system and language development.
