I went to an interesting talk yesterday about the BBC micro:bit. What is that? It is a small device that the speaker summed up in contrast to a couple of devices in the same ballpark: much more a ‘thing’ than a computer like the Raspberry Pi and less technically demanding than the Arduino. It is small, inexpensive and comes with a number of I/O components built in, like LEDs, buttons and even a Bluetooth radio.

So, I learnt what a micro:bit is but also some interesting reflections on what had been learned from the process of developing it. Not every lesson was clear-cut (for example, do deadlines get things done or mean that results are released before they have been properly optimised) but lots to chew over.
