ArduPilot and other Arduino-based DIY Drones projects.
Chris Anderson, editor-in-chief of Wired Magazine, has a write-up of the ArduPilot autopilot system and other Arduino-related discussions on his DIY Drones blog. The ArduPilot is billed as “the world’s cheapest autopilot”: a $110 system including PCB, GPS, and related components for piloting a hobby plane. DIY Drones is an amazing group creating all kinds of Unmanned Aerial Vehicles (UAVs). And, of course, publishing source code and Eagle files as they do.
