Hello,

I'm looking to finally build my Lehman seismometer and I was wondering what
are the latest recommendations in the construction. I've downloaded many of
the changes and recommendations that people have submitted. I have one
question, is the pickup coil and magnet still the best method to detect
motion. I thought I saw some mention of using Hall-Affect devices as
sensors. Any hints are much appreciated.

Thank you
