SEAN-THOMAS, et.al
Thanks for the advice on using a 10 ohms resister for damping my new STM-8 
moving coil sensor.  My unit worked as soon as constructed netting me two 
earthquakes the first day of operation and approximately one to three each 
day there-after.  And almost as rewarding my wife loves the look-she says 
that it looks so professional!  I am going to now do a lot of experimenting 
with it, possibly purchasing one of Larry's boards next month.  In the 
interim, please know what a great debt we all owe you for sharing your design 
and allowing us to pester you with so many questions.
