This video and the PDF present a simple way to build a passive radar system (using low cost hardware and free software) to determine the velocity and position of an aircraft . So far not small enough to be mounted on an UAV but maybe one day.
The video (51 min) is the presentation of Eric Blossom at the 22th Chaos Communication Congress
I built my own quad from scratch using an alu frame and decided to control it using the ardupilot mega that I have lying around. I loaded the arducopter NG2 code on this and took it for a couple of flights, noting its behavior and how it felt like controlling it. My intentions are to make this a platform that is really easy to control from first person video too, as…Continue

I've been working hard to try and figure out this center of gravity deal. After enduring half a dozen crashes I finally got it right: I threw the airplane, the thrust was perfect, it was going just fine until... I pulled up and it went down. Thats right, my control surface orientation for my elevator was reversed. By the time I realized what had happened it was too late, and the MTP made its…Continue
Awww yes finally time to do some PID tuning. After my last field test it was clear I needed to replace my motors with better quality ones and do some more PID tuning. After making a few mods to the airframe for added support and installing the new Jdrones Purple 2830 /12, 850kv motors with 10x4.7 props it was time to start testing again. In the first part of…Continue
Really cool way to use a POV on top of a helmet, and a hexa Mikrokopter to get all the action! Jason, if you are reading this, the arducopter code needs to…Continue
I just got the new Hobbyking Bixler, their newest EasyStar clone, and I'm very impressed. I haven't flown it yet, but based on the design I think it's the best Easystar clone out there yet. (And I've tested them…Continue

Here is the flight of my modified Mentor equipped with APM 2.2.0 build 3036.
The Mentor has been modified with two motors on the wings for a total power of 500 Watts,in order to make room for the camera on the nose and for equipments in the fuselage.

A special thanks to Max Levine for his fantastic work on the new instruments. The instruments and 3D model can be set to a "smooth" setting for those of you with processor to spare. This setting can be changed in the File, Settings, Instruments tab. For the best performance, do not select smooth for the instruments and don't select the 3D model instrument. Plus the turn coordinator is…Continue
