    I am pretty green in this area and fascinated by the capabilities of the 9 DOF sensor stick. I have so far tried getting outputs with two axis accelerometers and 1 axis gyro. Outputs are not easily understandable (e.g. When I oscillate a torsion pendulum I get oscillation around channel No. 610. Why? It should have been 512th channel where the pendulum passes through 0 degree (highest rotational velocity! Given this problem, I beg someone to help me finding the instantaneous directional vector of a box which is arbitrarily moving/rotating around from these 9 DOFs. Is there a programme readily available which combines these outputs and spits out the Euler angles, just like Shake/SK7 which I just discovered on the net? I would have been happier if the clock were also attached.

    This tutorial was very helpful. Thanks.
    By the way, can’t you put a time stamp with every output? That would allow us to plot the variations of the locations, velocities etc. with time. Is there any product along these IMUs. That would have been a real bonus.

No public wish lists :(
