Re: Clock or anemometer?

As the pendulum Q is rather high the important components of infrasonic frequency would be up to 2 Hz at most probably.  Bepi, I think the baro sensor you are using may be able to sample fast enough to sense this (not sure whether it's sensitive enough though).  Would be an interesting experiment.  Though the period graph shows a symmetrical noise waveform it would be interesting to know what its spectrum is and how it integrates over time into time error.
