摘要:Based on a survey, we describe the demographic and motivational structure of one open source hardware (OSH) community and compare it to open source software (OSS) communities. Taken separately, both the demographics and the motivational structure of the OSH community fall clearly within the typology of OSS communities, but when the two are taken together the OSH community forms a type of its own. We also discuss bottlenecks in OSH development revealed by the survey and subsequent interviews.
