In 2005 David started working on open hardware techniques for telephony. The idea of open hardware (people collaborating to build free hardware designs just like open software) was a big experiment, especially when it came to commercial products.
Much has happened since then. New projects, and even businesses have spun out of the project. Coolest of all – open hardware products are now in volume production. People are buying and using these products – often in preference to products developed using traditional closed development models. Open hardware works!
