Cefn Hoile sculpts open source hardware and software, and helps others do the same. After 10 years of industrial R&D, Cefn founded Shrimping It to help schools and hobbyists source and adopt electronics prototyping materials in the classroom. One of the project's freely-licensed builds, "The Shrimp", is an Arduino-compatible breadboard layout on which the ShrimpKey and Picussion projects in the book are based. Cefn is currently completing a PhD in Digital Innovation at Highwire, University of Lancaster, UK.
