A lot of people on the EZ* forums are coming to my fly-in here in NM on May 14-17.
I would like to invite all the DIY Drones to join us as a lot of you use the EZ* as a platform.
160 acres, nearest neighbor 2 miles, nearest town 3.5 miles.
2 n/s e/w dirt runways with no trees too close. (crop circle runways !)
Plenty of RV/Tent space and good hotel/motels in town.
Draw X on state of NM and fly-in is at center.
For more info, email email@example.com

Here in Boston, we have snow and wind. Not good for testing landing code. I hope to have some time in a few weeks to test and post the results of my new landing code. The old landing code can be seen in this video. Unfortunately coming in for a single approach like this has the EZ-STAR touching down at 28mph, and taking about 800 feet to land. The new landing code which I flew a few weeks ago does it in 300 feet.
The new idea is to circle in a radius of 125… Continue
For those of you that have a CHR-6D IMU, I thought that you might be interested on the testing I have done on a quad-rotor. I basically took the open source software that comes with the IMU and implemented Bill's DCM algorithm on the on-board STM32 MCU. Then I interfaced the IMU with the quad-rotor controller (I had this done a while ago) and was able to have a fairly stable flight. It is not perfect but definitively usable. To reduce the effect of vibration on the… Continue
attached is example of ArduPilot Ground Station that logs KML data, as well as displays plane path during flight. (plane icon is current position and flight path is yellow with green bars, but I have lot's of data packed so it's hard to see green in the attached pic).… Continue
This gets ever more grown up, well worth a look......
Here is our unofficial and unauthorized Attopilot-compatible GCS. It is free and open source, and features:
Standard "T" flight instrument layout.
Standard aviation industry units.
Over twice as fast as the official GCS replaying log files, and a similar level of performance improvement with live telemetry.
Integrates with Google Earth to provide realtime UAV tracking.
Generates time-stamped KML… Continue
So, my Makerbot is now working. It took some doing. My first complete build is shown--a Darth Vader helmet, which worked pretty well for a first try. But as you can see, I've still got some tuning to do.… Continue
Working as a BYU electronics shop tech, I occasionally get to help out the guys at the MAGICC lab. A PhD student came in a few weeks ago with a problem: He wanted to make an Alpha-Beta probe. Encoders of the accuracy he wanted are too heavy and too expensive to put on a 5 pound flying wing, and the multiple Pitot-tube option was not his game to play either, so he was wondering if we could make encoders like the big expensive ones he was looking… Continue
New in Ardupilot 2.5 is mission simulation/debugging. First load a mission using the config tool and make sure you select "Set Manually" in the home info area on the left.
Then, in the header, set the value of Debug to 1 and upload 2.5. The mission will begin as if it's already in the air and will start outputting telemetry. If everything is OK, the plane should make each waypoint and end up back at home in a Loiter pattern.
This is also a 3d simulator, so altitude will be… Continue
I wanted to talk about a new aspect of 2.5 that enables coders to easily program missions through a simple API. The main idea is that many common events are sent to functions in the event.pde file to be handled by you in any way you see fit. You can do anything and access any variable in the system - within reason. The events.pde file can be swapped out with a different mission and uploaded to the the hardware.
