"It’s safe to say that drones are the first technology in history where the toy industry and hobbyists are beating the military-industrial complex at its own game." Oh, really? Mr Limdbergh begs to differ: http://en.wikipedia.org/wiki/Charles_Lindbergh He got some training in the military but he then beats them later. Technology has been historically been pushed as much by civilian industry as the military, or more.…

"Ethernet and laser all those amazing tech was created by private companies and computer networks were created by enthusiast before DARPA."

But would we ever have actually had the Internet before DARPA? It took over 30 years before the Internet actually became a mainstream and profitable thing. If the net had been developed by private companies then they would have done it in such a way that would have let them become profitable within a year or two, so it's unlikely that the net would be anything like what it is today. And for all it's flaws, it's hard to imagine it being better if it were developed by private industry.

The DIY copter crowd does some pretty sweet stuff (both autonomous and piloted). Here's a fun video shot by a guy who built a first-person-view Hexacopter: http://vimeo.com/18873955

http://www.youtube.com/watch?v=hU0_tGHlR7g All of the RCExplorer videos are awesome, and they're shot with a very low-tech drone (a tricopter with only roll/yaw rate stabilization - just piezo gyros and no attitude stabilization at all).

This one caused a _lot_ of controversy in the FPV (first person view/video) RC community a while back:

if you don't have the time/patience to watch the whole 3-ish minutes, try this but:

> Indeed, some of the newest sensors combine three-axis accelerometers, gyros, and magnetometers (nine sensors in all), plus a temperature gauge and a processor, into one little package that costs about $17.

which model is he talking about? i got curious and went looking, and the best i could find was $50

How loud are these hobby/open source drones? Spy-worthy?

They could land and perch silently, but when flying they are really obvious.

Not all drones have to be quadrotor helicopters; with a fixed wing drone you can glide over your target with the propeller stopped and make very little noise.

Chris would be talking about the new MPU9150 from Invensense: http://www.invensense.com/mems/gyro/mpu9150.html

Pricing isn't public yet but you can get an idea by looking at the 6-axis products.

I find how this is now all playing out to be quite interesting, and a little amusing:

A few years back when there was really only one prominent open source UAV system (Paparazzi), nearly everyone was focused on turning (fixed-wing) radio-controlled planes into hobby UAVs. Back then we didn't have gyros or accelerometers, we used thermopiles to detect the heat difference between warm ground and the cold atmosphere on four axis. This worked well until it became night time or started raining, and required a baseline calibration before most flights.

When projects like OpenPilot and Ardupilot (aka. DIYDrones/3DRobotics) first started to appear they were focused on building UAV systems for planes with this same technology, multi-rotor vehicles where only just on the radar at that stage. They were expensive and to be frank, not very good at flying stable. Then game consoles like the Wii came along and over the next few years gyros and accelerometers started to become much cheaper.

OpenPilot and DIYDrones/3DRobotics initially started out developing with these new gyros and accelerometers in planes, but it wasn't really the right platform as planes tend to me more costly and fragile in a crash, which is inevitable when developing with these new technologies. OpenPilot initially started to adapt their system to multi-rotors (aka. quadcopters) as a way of quickly testing new code and new algorithms for planes. Unlike planes we could even now test code indoors.

Quad-copters started out as a utility, to lift heavy items or as a test-bed for fixed-win UAV algorithms. From there they have now become the first class citizen in the world of open source and hobby UAV projects.

I think this is all really just starting to ramp up. The hardware we need to build these systems is pretty much all there, it can get faster, smaller and cheaper but innovation there is nearing a plateau. On the other hand, I think software is still very much in it's infancy. There is still a long way to go in making these systems reliable and repeatable, and most importantly user friendly. We have progressed from having to re-compile under linux to change one PID setting value, but the barrier to entry is still quite high on the technical side of things.
