John,

I agree that visualization is VERY difficult sometimes, but I hesitate 
creating a separate blog since it might water down the discussions here. 
People might move to the blogs instead of here and some might be left out of 
the comments.

I am doing a "desktop experiment" right now with this and it would best be 
show rather than described.  I am suspending a ball point pen, as discussed. 
On the other end of the pen is a ring magnet which is suspended about 1/2" 
above the edge of a spool of bulk wire, which is connected directly 
connected to my electronics.

Thus far, it detects my walking up to the desk and other movements.  I am 
allowing some time to see if an EQ event happens (I hope).  Of course, it is 
not damped and movement could be in any direction.  I haven't crossed that 
bridge yet.

Jerry

The discussion of various hinges and seismometer designs is very
interesting, but in many cases I find it difficult to visualize the
exact setup that is being described.  A photograph or a sketch would
be very helpful.

One way to do this is to start a blog.  It's easy to do
at:  http://blogger.com.  I started a blog, just to see how it
worked, and it only took a few minutes to add an entry.  My "trial"
entry shows the AS-1 sensor:  http://seismoedu.blogspot.com/

I'm sure there are other posting options as well.

Cheers,
John
