I have a UAV Dev board and have added a HMC5843 magnetometer from Sparkfun. My telemetry is already sending GPS data and IMU computed data but I would also like to return the magnetic heading. I am using recent Dev Board code, where can I extract the magnetic heading? See More
Darryl Uchitil replied to Ben's discussion sending UDB telemetry data over video link + decoding with a video grabber card + showing a virtual cockpit in 3D etc"I too thought of piggybacking some data on the video, as who needs yet another transmitter draining the batteries? To start I built a close-caption decoder from here: http://www.brouhaha.com/~eric/pic/caption/, and tested it with a…"

Thanks for the SKP. Last time I played with Sketchup, someone has a 3D mouse to show(www.3dconnexion.com). Now I wish I had one of those. Played with Sketchup yesterday, without watching tutorials. Got something reasonable on the screen using…"
Darryl Uchitil commented on Bill Porter's blog post My own DIY drone, complete with LabView 'Ground Station'"Very nice ground station. I like the 3D representation of the rover I am working on a lawn rover, using a java-based dashboard. I have not used Sketchup, could you send your SKP file?

You can find the HW…"
Darryl Uchitil replied to William Premerlani's discussion robust estimator of the direction cosine matrix"Sean,
In the long run, I want something to cut my lawn (2.5 acres). For now (testing) I have a salvaged Power Wheels run by a 32-bit Coldfire-based industrial computer which was left over from a project at work. The lashup has GPS and I plan to send…"
Darryl Uchitil replied to William Premerlani's discussion robust estimator of the direction cosine matrix"Sean,
Thanks for the artificial horizon link. Regarding your dashboard, it is often easier to modify an existing application rather than create(design) one from scratch. That said, I am somewhat less than a VB guru, and have only dabbled in VB at…"
Darryl Uchitil replied to William Premerlani's discussion robust estimator of the direction cosine matrix"Sean,
Nice video and I love the dashboard you are using. I am just getting started with this hardware for a land-based rover, and I see a lot of debugging ahead. What are you using for the dashboard display, and can I get a copy?
Thanks,
Darryl"
