Open Source, it's not just for software. It's for hardware too. The new film, Arduino: The Documentary, revisits a project launched in the Italian town of Ivrea back in 2005. The challenge? To develop cheap, easy-to-use electronics components for design students. (You can get into the technical side of things here.) The message? Geek.com summarizes it well: "we are about to see an explosion of hardware devices that come from bedroom tinkerers and student projects." Note: A Spanish version of the film is available here, and they're all released under a Creative Commons license.
