Small Unmanned Aircraft System Full ARC Document.

I have noticed that many people aren't aware of the full ARC/FAA document released in April 2009. It is 74 pages long, as opposed to the handful of pages on the AMA website that many seem to be using. Lots of info on what may be coming our way, esp. when I doubt that recreational users wil have less limitations imposed than commercial operators (IE: 400 ft ceiling and 1500' lateral distance)…

AMA official response to NYC FPV video

New York City First Person View Video

A recent video posted to YouTube depicts a First Person View (FPV) video flight of an unmanned aircraft over New York Bay; Long Island; the Brooklyn and Manhattan Bridges; Liberty Island and the Statue of Liberty; over and in close proximity to buildings, occupied vehicles and water vessels; and directly over unprotected people. The nature of the flight was outside the realm of recreational aeromodeling activity as defined by the AMA Safety Code…

Bruce Talbert, national airspace integration lead at the FAA's unmanned aircraft office, 2009 statement on recreational use of sUASes

From this interview in 2009. Totally unambiguos statement on model aircaft (recreational UAS):

“The FAA certainly doesn’t want to regulate model aircraft,” Talbert said. "Model aircraft are not to exceed 55 pounds or fly at an altitude of more than 400 feet. They must remain within the line of sight and not operate within three nautical miles of an airport or heliport", he said.

Seems to have been (and still is) the concensus at the FAA for…

Testing a DIYDrones magnetometer in HK's GCS

Testing a DIYDrones magnetometer in HK's GCS from Pete Hollands on Vimeo.

I test the DIY Drones magnetometer ( HMC5843 magnetometer breakout board ) using Happy Killmore's Ground Control Station connected using SERIAL_UDB_EXTRA telemetry format, to a UAV DevBoard V3 running

MatrixPilot (revision 729 of trunk).

BASIC Stamp: Board of Education

I have a Parallax Board of Education. I was wondering whether I could use this for my first UAV. All I would be doing is having the plane fly in a circle formation. Would this work?

Improved Altitude Estimate

The barometric sensor alone in most cases provides noisy and drift prone measurements. I have been trying to come up with a simple way to implement a fixed gain filter to utilize the acceleration measurements from the accelerometers to help clean up the noise and also add a sanity check via sensor fusion.…

Dallas Area Programming for APM PPM Encoder

If anyone in the Dallas-Ft Worth area has an APM that has a misprogrammed PPM encoder, I have the AVR programmer available and have successfully reprogrammed three older APM boards. Send me a message if you would like to have your APM PPM encoder reprogrammed with the correct brown-out voltage.
