In this paper we discuss the role of open-source hardware in supporting creativity. We use the case study of an opensource FM radio and explore the modes of creation that emerged from a workshop in which participants modified and produced the design: making, personalizing, designing, engineering, and experimenting. We contrast open-source hardware with other approaches to supporting creativity and explore some of its unique challenges and opportunities.
