Here is a video (http://www.youtube.com/watch?v=WnAL1ygwNg8) of a new implementation of an AHRS algorithm, thanks to Seb Madgwick and Fabio Vareseno works.

I haven't flown much of anything because of the weather, so I decided to see if I could do something different with my ArduIMU. I decided that if I could get a MIDI port to read the IMU, I might be able to make music.
I used a VBscript to read the serial port and send pitch data from the ArduIMU to a slot. I then used a MIDI program to record the…Continue

I've made a quaternion based AHRS with bonus altitude and temperature sensing using an AltIMU-10 and an Arduino Nano. It can print out orientation in either Euler angles (heading, pitch, roll), a north-east-down rotation matrix or as a quaternion over UART serial.
Time to start build next version of antenna trackers. As antennas are getting bigger and bigger we planned to make one heavyduty antenna tracker that can turn 2kg antenna clusters.
I build a couple of DIY electronic devices from open source projects.
I thought those could be useful to someone here on DIYDrones and they deserve a little visibility here too.
They are based on Arduino Nano and very cheap to build.
In this video I'm using both for the first time, with my…Continue
HefnyCopter2 implements full PID terms that is P, I & D. It uses the following approach.
My vision is to keep math as simple as possible and use superposition to accumulate different behaviors together based on my…Continue

In this video the application of a Visual-Inertial (Camera & IMU) localization algorithm on a Parrot AR.DRONE quadrotor, for enabling real-time GPS-denied autonomous navigation, is presented.
A sensor package for data logging, consisting of a Beaglebone computer, an…Continue
I've been thinking a lot lately about how cool it would be to implement inertial dead reckoning on ArduCopter for a gps-free loiter mode of sorts. I just wanted to get some discussion going from people who have studied this or have tried implementing it, as I know it is difficult.
To begin with, this is a good…Continue
I have recently performed flight tests on a major change in the way acceleration is accounted for in performing roll-pitch drift compensation from accelerometer measurements. The theory behind the idea was recently published in a…Continue
DataSheet offers little in the way of gyro stability or…Continue
APM Mission Planner is adding more support for the AttoPilot Voltage Sensor. Thus the Open Hardware Store has introduced a voltage sensor kit that is ready to be used and you just need to plug it in and configure Ardupilot. It comes with XT60-connectors and a 15cm long servo cable to connect to the…Continue
Nice IMU project spotted on Dangerous Prototypes with MEMS gyros and accelerometer, Cortex-M3.
"The IMU is supposed to be high-end, implementing state-of-the-art data filtering, best low-cost MEMS sensors available and many features to compete with commercial IMUs used in…Continue
This is an interesting board - perhaps most interesting is the approach to driver-based sensors in the…Continue
After experimenting with several dead-reckoning algorithms over the past 2 years, I finally have a simple…Continue
I think it's perfect!
- Tri-axis gyroscope and tri-axis accelerometer in one package
- Programmable scale ranges:
- Gyro: ±250, ±500, ±1000, and ±2000°/s
- Accelerometer: ±2g, ±4g, ±8g and ±16g
- Output: rotation matrix,…Continue
