For anyone who's interested, I've just put together a page of my system, 
which is centered around a Galitzin-type seismometer that I built in a 
metals-tech class about 15 years ago. Includes pictures, schematics, and 
the story of how I built the system...

Judging by the messages I've been reading on this list, my setup is very 
basic, and there's lots that I have to learn. For example, I still 
haven't connected it to a computer.
