The interesting story of how the go-to project board(s) came to be. [via Wired]

The first board prototype didn’t look like a
killer app yet. Then they made it open source.

Released in 2005 as a modest tool for Banzi’s students at the Interaction Design Institute Ivrea (IDII), Arduino has spawned an international do-it-yourself revolution in electronics. You can buy an Arduino board for just about US $30 or build your own from scratch: All hardware schematics and source code are available for free under public licenses. As a result, Arduino has become the most influential open-source hardware movement of its time.
