Hi James,

Thanks very much for the E-Bay note on the seismometer!  The pictures were ~
vague, but I think I see the flat metal strip on top.  Interesting hanging
mass approach.  I am "speculating" that it has a photo sensor
on the bottom for rough centering purposes?  The seller may send a PDF
file on such which might
also give more overall insight.

Makes me wonder whether a round piano wire that replaces the flat metal
strip would work out?
