Hi,

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…

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…

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.

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…

Team,

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…

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…

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…

This is an interesting board - perhaps most interesting is the approach to driver-based sensors in the…

Team,

After experimenting with several dead-reckoning algorithms over the past 2 years, I finally have a simple…

New Part on Mouser.

Airspeed sensor for about 30% the price?

InvenSense MPU-6000

I think it's perfect!
