Hi Barry and all,

Glad your STM 8 is still working.  Sean-Thomas
Morrisseys vertical seismo created alot of interest ~ afew
years ago of course.  I think it also had alot of confusion
along the line of the exact electronics components used and
its adjustments involved for various reasons.....their was a
long line of emails with corrections thereafter that kind of
left me and perhaps others in the lurch so too speak.  It just
might be that you are the only "knowledgeable person " left
that perhaps has some more exact circuitry/operation/setup
info than anyone else.  It was a rather involved circuitry I
think.  You may even have changed components that would
be of interest also.  Its perhaps prudent to say that these
corrected documents (however assembled) are invaluable to
those wishing to try a duplication.  I've little electronics
background myself, and I'd guess most individuals are in the
same rough class.

I think St. Louis University "was" thinking of trying to get a
U.S. Patent; but as of recent date, I've seen nothing suggesting
such (it could be in the "pipeline", so too speak of course).  On
the other hand, it may have been set aside for other financial
reasons; or even abandoned.  Its also possible that the STM
website display with the mechanics and circuitry itself prior to
any Patent application could have placed the entire unit in a
"public domain" category which in itself prevents any Patent
granting success.  I just don't know.  Regardless, its "still"
likely the best broadband vertical design around for its
cheapest home building approach.....which I'am sure Sean
was encouraging.

There was a number of individuals trying to duplicate the unit,
but, I've no idea of their success.  As I recall, one or two
were considering other sensor/amplifier methods outside of
the original design, but I've no idea of how that went.

Take care, Meredith Lamb
