First test of targeting system. All calculations are done in the air.
Camera provides two streams. Highly compressed (rigth window) and detailed (left).
3 axis BL gimbal. In low light conditions and excessive vibration.
John modified a point-and-shoot camera to capture near infrared images. This is half the puzzle in building NDVI images for analyzing crop health.
Information on the conversion can be found here: …Continue
A couple months ago I was testing ArduPlane and some of the different modes. I was not getting on very well in FBW-B* mode. If you look at the image below. You will see the purple track. I was loosing altitude and I couldn't understand why. You can see just before the path goes red, I'd lost a lot of…Continue
Nicknamed "Laurel and Hardy", for reasons that should be obvious.
Everything calibrated...time to get the PID's done! Well..once it stops raining and snowing here in Switzerland. :-(
Some build annoyances, which I'll go into in an additional post.
Another cool Kickstarter project. It looks like it works well on the ground, the video doesn't show very much of the flight performance. It does appear to be quite robust at least. Thanks to…Continue
I built this guy out of PVC plumbing parts from Canadian tire and an old plastic food container:…Continue
Because the latter one of condor drone tests went very well in the navigation, I decided to mount the camera aboard the condor photography for mapping and the results appear promising.
Several months ago I started working on a system called Afterflight to organize and browse my tlogs and dataflash logs, sync them with video, and view them along with a map GPS display. It still has a long way to go, but there is a fair amount of working functionality so I figured I'd get it out there…Continue
Here is a short video of the design, build and crash testing of the Game of Drone's Battle Quad. It's waterproof, bulletproof, and can fly away from almost any crash.
"Fly 'em hard and put 'em away wet. They're only drones"
I had a couple of requests for a still shot of the 12-rotor beast that Joe and Justin cooked up, so here it…Continue
This might be a common knowledge, but in the last months I haven't seen a similar post. Maybe someone new to barometers might be interested in this data.
The GPS receivers return altitude data, but this is inaccurate. The error margin depends on the satellite constellation geometry…Continue
Last Wednesday I went out to the field for some flight tests and gains trimming. Other people where flying their model planes there too. We usually follow a counter-clockwise pattern while flying to avoid collisions. That day I was flying especially slow, so when I took the turn, I did so on the spot and…Continue
SAN FRANCISCO — As wildfire season begins in Western landscapes that were covered in smoky haze for weeks at a time last summer, the federal government’s…
Can anyone put me into hibernation for 5…Continue
I want to let the APM trigger my camera and the camera I had did not have a port for a remote shutter trigger so I had to remove the button on the camera and solder the 4 points and connected them to a relay switch.
Raw flight footage.
Just to document some early progress in the building of a multirotor Conservation Drone with thermal imaging for wildlife research (last picture shows the quad with a FLIR PS32 camera, yet to be mounted). Apologies for the shaky video taken with an iphone (had to hold on to transmitter with other hand).
Every year or so, some research group posts a video of a "cyclocopter" flying. I'm not sure why (this article suggest they might be more efficient than traditional helicopters, and that people have been pursing them for a…Continue
