Dear Robert,

The best place to start getting information for a home-built
seismic system is with the Public Seismic Network.

The web site URL for one of the principal PSN sites is:
http://psn.quake.net/

The mailing list sign up and list archive are here:
http://psn.quake.net/maillist.html

This is an active and friendly group that is very willing to
help people get started in seismology.  They also post 
seismograms on the web site so you can see how a quake looked
at a different location.

Good luck with your system.
