Arduino enthusiast "ericdamtoft" has demonstrated a fascinating yet relatively simple motion stabiliser controlled with an Arduino. Using an accelerometer the device can measure it's position in two dimensions and then control two matching servos to keep a small platform level with the surface. This would have use for photography or video on a moving vehicle, boating or have use in the robotics arena. And it really works well - check out the following video:
This tiny 3-axis accelerometer module can operate in either +/-1.5 g or +/-6 g ranges, giving your project the ability to tell which way is up. Ideal for robotics projects, tilt sensors, vehicle data loggers, and whatever else you can dream up. For more information and to order, click here.
