Please tell us a bit about your UAV interest
I fly model planes and helicopters, and I'm a software developer. UAVs seemed like a pretty logical next step.

Here are a few videos of my custom quad rotor - scratch built and programmed.

Saw this today: http://news.yahoo.com/blogs/sideshow/drone-hunting-colorado-172357477.html

It's interesting that the article leads with a photo of a hexacopter, calls it an octocopter, and the drone bounty…

Configuration tool preview

Posted on December 13, 2011 at 3:18am 2 Comments

A number of people have expressed interest in building quads based on mine, and using my software.  In order to help get them set up quickly, I've started working on a real-time diagnostic and setup tool that interacts with my quad flight software.  My flight software looks like it'll be compatible with at least one commercial board (the HoverFly Sport) as we use the same MPU and gyro sensor, so you'll be able to buy their hardware and try my flight controls if you…

Outdoor test video of my latest quad

Here's a better video of my latest quad / code. I doubled the maximum angular rates in anticipation of some stunt flying. I probably still have to bump them higher, but I wanted to see how it handled, if it affected stability, and so on. It's just as stable, but much more nimble.

I've done some more work on the stability code in my Propeller-based quadrotor and gotten significantly better flight performance.  It still needs some tuning, but all my oscillation problems are gone.

I briefly dug through your code and let me join the long list of others in congratulating you!  I too have been working on this for quite some time and can say that all the time and effort will be well worth it the first time you see it fly by itself.
I will send over my updated code soon with some basic control algorithms that you might like to take a look at.  I spent quite a while testing the DCM and quaternion based estimators with flightgear (which I highly recommend for dialing in your gains and velocity correction algorithm (and it's super simple to implement)).  Good luck and I hope to hear back from you!
