Speedmaster

The winning circuit in 3D

Published in issue 365, May 2007

Speedmaster
Here is the circuit voted winner of the International R8C Design Competition by Elektor Electronics readers: an intelligent 3D accelerometer that not only measures acceleration on all three spatial axes, but also calculates the total distance moved. And, as promised, a ready-assembled printed circuit board!
