When I first got started with RC, one of my main learning resources was the excellent weekly podcast "All Things That Fly."  Two years ago they had some guy on with the crazy idea that the planes could fly themselves, and had a website that talked about open source hardware and software that could make such a thing happen called diydrones.com.

This week Chris reprises his appearance, talking about "drones, stabilization, geofencing, obstacle avoidance, 3D printing, CNC milling, and more."  Co-host (and commercially licensed pilot) Lucien Miller gives about the best summary of potential drone pilot licensing issues I've heard.

While you're there, be sure and subscribe to ATTF if you're not already a regular listener.  It should be interesting and informative to all diydrone.com regulars.
