Although many single board computers (SBC) exist, the Raspberry Pi Foundation made a huge impact with their range of SBCs, in part due to the availability and low-cost. The Raspberry Pi currently supports a variety of Operating Systems including BSD, Debian, Risc OS, Windows, and many Linux variants. Although originally designed for the educational sector, the Raspberry Pi is used in a variety of projects ranging from Engineering research to Art exhibitions.

In this book, we try to capture a cross section of these projects and research applications to show how the Raspberry Pi has enabled people to experiment in new ways. We would like to thank all authors who have contributed their work to this Special Issue.
