Believe it or not, the Raspberry Pi is almost ten years old. In this relatively short period the Pi has ushered in a new revolution in computing that stretches far beyond its original remit which was to promote basic computer science education in schools.
There have been several Pi developments over the past few years. The Pi Zero was released in 2015, and the Pi and its ‘essentials’ kit is available for less than £10 (around $13, AU$18). The Pi Zero W was added to the Zero family in February 2017, featuring a 1GHz processor, 512MB RAM and support for Wi-Fi and Bluetooth, again all for just over £15 (around $19, AU$27) with accessories.
