We had our first Rather Useful Seminar today. It was all about hardware, made slightly more interesting by the way that hardware, in the form of my Bluetooth keyboard and mouse failed me right at the start.
But thanks to the loan of spare keyboard we managed to get going and play around with Arduinos. I showed how easy it is to write programs for the platform and how many amazingly cheap components you can find on eBay. (In fact I ended up spending around 5 quid doing "research" for the presentation when I bought a 1.8 inch colour screen and an SD card interface)
Anyhoo, it went well enough and folks seemed to have a good time. If we have enough interest we might start a Hardware Fiddlers club of some kind in the department. You can find my slide deck and details of future seminars here.
