Raspberry Pi
I bought a Raspberry Pi Zero for under £5 from PiHut. It's an amazing piece of kit - a desktop computer on a board the size of a credit-card.
My first project with it was a Birdsong analyser and Bat Detector

Following the success of the bat detector I decided to try something more ambitious, the ArcSyn-0 Synthesiser
