Hi Everyone,

This list sure has been quite....Recently I got an email from someone in
Germany. They have a Lehman type seismometer in their school. Their sensor
has a unique way of mounting the boom to the frame. The link to their main
page is http://www.mgm.monschau.de/seismic/main_en.html and a description of
their sensor and how a garden gate horizontal sensor works starts here
http://www.mgm.monschau.de/seismic/main_en.html.
