We often get questions from newcomers who are confused by all the Ardu* nomenclature here, so I made the above product comparison matrix, which you can find here.
And just to extend this to the full family, including…Continue
The 2012 AMA Expo (happening this week) will be featuring the NASA DROID, a drone that's being used as an educational vehicle for high school students.
Come and see and learn how NASA Dryden Flight Research Center uses the DROID or Dryden Remotely Operated Integrated Drone for flight research, pilot training and the INSPIRE student internship program.
The DROID is one of four aircraft used for…

Gyro stabilized mount works quite well. The roll servo does seem to be a bit jerky, but from the forums it seems its one of the downsides to digital servos. What about a small air shock absorber? A trade off of reaction time for fluidity of movement. Although, the platform is for photos not video...
A somber ceremony begins, as the machine which caused Major Marcy to sever all contact with us is dismantled & returned to its role as an aircraft position tracker.
The construction of an indoor test harness greatly…Continue
Just built a suprisingly good flying quad. Total price with battery but without receiver and APM was $127. It's very usable indoors and later I will add GPS mag, xbee and fpv tilt roll cam today.…Continue
Happy new year!
I've put together a proof of concept autopilot based on the Lyapunov Vector Field path following stuff documented in various UAV research papers of the last many years. It is here:
a) it can fly JSBSim,…Continue
Happy New Year to everyone!
I found this articles while searching methods for effective PID tuning:
The method is described here:…Continue
Put together a quick series of my favorite clips of MyGeekShow over this last year, and quickly discussed 2011's goal and how it was acomplished with the Nova.
Was able to go from building simple gliders to building the Nova - an airplane completely designed, built and flown by me, a huge success as I can now create an airplane to specifically meet the needs of any objective.…Continue
Didn't intend to take any pics (the hat portion of ye olde hatcam being misplaced), but things went so well I was able to fly one-handed and hold the iphone in the other hand. Beautiful!!
From the air. I hadn't planned on doing this either, but things were so…Continue
An oscilloscope turned out to be a pretty handy debugging tool when trying to troubleshoot my APM2 ESC problem. Here's a shakycam showing how I used mine to verify the problem was with the ESC and not with the APM2.
I got everything together last night and couldn't wait until the morning to go out, so I took a quick flight in the basement. Stability was pretty good. I made a quick video of simple mode too.

Both Andreas and I had the same problem... fortunately he had it before I did, and had figured out a workaround.
Problem: when powering up, not all motors will spin.
Workaround: apply power to the APM2 before attaching the main battery. You can do this either via USB or by attaching a spare battery/ESC to one of the output lines. As soon as the board boots up, hook up the main battery and remove the second battery.…Continue
This is my second flight with the GU-INS in GPS Hold mode
ArduCopter in action: Testing the QuadCopter (HIL mode) on X-Plane v9
Here a video a the ArduMega board (2560 or 1280) with the firmware ArduCopter v2.1.1b (JLN update for X-Plane) connected on the X-Plane simulator throught the APM Planner in HIL mode. The QuadCopter QRO has been modelized for X-Plane v9.0 (or greater) so as get a closest replication of a true QuadCopter UAV.
This is a very good method for testing all the features of the ArduCopter…Continue
An interesting discussion of the risks and benefits of automation for air and other forms travel.Continue
Quad-copter equipped with the advanced AS3X by Blade (Horizon Hobby)
Ahhh the holidays.
I'd never have the time for an indulgence like this little project any other time of year.
Very interesting video from VectorNav showing what high frequency noise and magnetic fields actually do to an imu.
Nice visual representation!
Also this vectornav unit seems to be quite the…Continue
