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. Clare Bowman enjoys hacking playful interactive installations and designing digitally fabricated consumer projects, exhibiting her work in the UK and abroad. Her background as a collaborator of shrimping.it has lead to an interest in exploring the Maker Movement and the potential therapeutic benefits of Do It Yourself (DIY) assistive technology. She is driven by an interest in supporting individuals discover their own creativity through an occupational therapy perspective.
