  • You need some mechanical amplification. In the typical picture of a seismograph you see a mass hanging on a tread from a support arm. I suggest a mass hanging on a thin rigid rod. The support rod extends past the support cross arm by a factor of 10. Say 10 cm down to large mass and 100 cm above support arm with the accelerometer at the very top. This should give a factor of 10 amplification to the signal. This works for the x and y axis. I do not see how to do it for the z axis (up and down).

No public wish lists :(
