Raspberry Pi is a small, cheap computer on a circuit board the size of a credit card. I spent a very interesting day in training today, learning how to use a Raspberry Pi with Python programming, creating small embedded systems and connecting to servers, with applications (in theory!) for the Internet of Things. Today a little red light, tomorrow the world!

World domination aside, it was the first time in years that I had built an electronic circuit, or done any microcontroller programming, so it was a very hands on day and a really fun change from my usual work.
