I've been working on the Perseus Autopilot for the past few weeks and unfortunately didn't find the time to post any updates on the Andromeda Blog. I'm in the process of writing about a few things about the AHRS that I've been building as part of the project and I should hopefully post that within the week.
Also in case it might be of use to anyone, I wrote a simple 3D visualizer for the demonstration above. It will read quaternion values from the serial port in the following format:
w x y z;
But you can re-write it to accept any format. You just need to write your own custom GetRotation function. It's developed in C# and uses WPF3D for the visuals so the codebase is very small. Unfortunately it limits it to windows only (sorry). The source include the entire VS2008 project and you can do whatever you want with it.
You can download the code from here:
