Back in December 2015 I created my first Raspberry Pi Zero based Bot. It was a little ungainly with cables looping all over it and a USB WiFi dongle sticking out the side but it was relatively small, moved around and, at the time, I felt there was still plenty of room to make it more compact.
The aim of the next variant was to squeeze all the components into a mint tin that was only slightly larger than the Pi Zero itself. This proved something of a challenge and it wasn’t until the release of Pimoroni’s Zero LiPo board and Average Man’s ProtoZero development board that I was able to get everything compact enough to fit inside.
