From the announcement on the LCA site:
"Genetic engineering at home? Teaching science on a low budget? Fully open mobile and wireless devices? The design and manufacture of development tools? Is it possible?
Join open source luminary Bruce Perens as he explores the Second Revolution of Open Source - Open Hardware.
Open Hardware is a movement dedicated to creating physical objects under the same terms and principles as Open Source Software. That is, their design and manufacture yields freedoms such as the ability to run the hardware for any purpose, study it, change it and share it with others."
LCA2012 will have a big Open Hardware focus, starting with the Arduino Miniconf (organised by Andy Gelme and myself) on the very first day. There are also a number of Open Hardware talks in the main conference, and having Bruce deliver a keynote on the subject just goes to show that it's arrived in a big way. So if you can make it along to LCA, make sure you register soon to take advantage of the Early Bird discount:
