Dear Oben,

I'm glad to hear that you are building a seismic system.  The best source 
of technical
information is the Public Seismic Network, through the archives of their 
Email messages,
through web sites, or by asking questions.  Sean-Thomas Morrissey
 , for example, is one of the experts in seismological 
instrumentation
who is in the PSN and he often provides answers to PSN questions.

To join, please see this page to join the group:

Best of luck with your new instrument.

Yours,
John
