I've created an I2C digital signal sonar module to avoid the noise problems I have been having with the current analog signal sonar module.
Seeing all the problems we are having with noisy sonar data got me thinking
Where does the noise come from? Is it:
Have just seen the following article on The Register:
Ok, so it is a touch pricey (£5000), but not so long ago, 3D printing was silly expensive. Then came RepRap and the others.

So I know this isn't exactly "DIY Drone-ish" as far subject matter, but I thought the interview was pretty interesting as Greg's approch to designing and testing new concepts and his RC Super Hero were so unique that it deserved to be shared.
Greg runs the YouTube channel "BornTaFly" and sells his models and PDF plans through…Continue

Over the last few months we have been testing our new hardware, launcher, airframe and autopilot. As the newest member of the team I've been taking responsibility for producing some new videos - the acquisition of a GoPro HD has resulted in some amazing footage. Such great video from such a small device!
This video shows a short flight of our…Continue
A short video of a very small UAV plane flying in an autonomous mode. Looks similar to some perching UAVs that I stumbled across a while back.
For the next version of APM (the fixed-wing codebase), we're thinking about adding an acrobatic scripting language, so you can program your UAV to do awesome robotic stunts. APM already suppports inverted flight, and adding other…Continue

I just discovered a nice online service where you can share your circuit design. Eagle and Kicad files are accepted. From the Website:
CircuitBee provides a platform for you to share live versions of your circuit schematics on your websites, blogs or forums.
Features include full zooming capability, panning, and even mouse over tips about symbols in the schematic.
It sure beats a blurry screenshot or a giant PDF!
Sign-up and get your circuit…
From IEEE Spectrum,a "cyclogyro", or "cyclocopter":
Fundamentally, a cyclocopter is similar to a helicopter in that it creates…
Almost all autopilots use PID algorythms in one way or another. Now there's a basic PID library in the standard Arduino software. Even better, here's a tutorial series from Brett Beuregard on how to use…Continue
I got my start in robotics with LEGO Mindstorms, so I'm glad to see continued sensor development there. Here's the latest: a 6DoF IMU from Dexter Industries. No word yet on what kind of software support it…Continue
I recently wrote my thesis on the topic of using feedback control to provide a vertical position autopilot for an RC helicopter. I used a Gaui EP100 on a test-rig to test the control techniques. The control theory has been designed so that it can be applied to a helicopter of any dimension/number of blades. It is presented in this 26 page document. I hope this can be of…Continue

I'm working on the MultinoCopter project since 2 months. It is a 50x50mm size board with full compatible arduino pro mini architecture and 9DOF imu. I didnt share it because i have to finish the multicopter code before. Now it is working as a serial IMU for the computer based projects (calculating euler angles) and camera stabilizer.
Yesterday i tested the camera stabilization code on the 3 axis. The mount coming from a…Continue
Do you know that chip which goes on Arduino USB Host Shield and ADK boards? Yes, that's Max3421 from Maxim. And that other one which integrate some text based OSD boards? Hmmm... OK it is the Max7456 from Maxim too.
Well, from now on, Maxim will be there on our buddy gyros too.

Finally, I'm posting this project to share.
This is my Quadcopter, a project born because of a passion hobby and a thesis research excuse. :P
