This Thursday [Sept 23, 2010] in New York, on the eve of Maker Faire, the Open Hardware Summit promises to break new ground. It features a packed schedule of thinkers from NASA to Texas Instruments to the Arduino project, and the introduction of a first working definition of open source hardware. Peter Kirn interviews project co-chairs Alicia Gibb and Ayah Bdeir about the origins and goals of the event, and some of the unique challenges of doing open source hardware.
