Hi all,
 Was particularly interested in the pendulum hinge; but, the photos don't=
=20
seem
to totally show exactly how they maintain position or their contact shape o=
r=20
the adjacent
"supports" they rest on. Indeed....the supports may well be glass but its=
=20
just a
guess, or, they are made of angled metal? I see no grooves in the supports=
=20
to keep
the hinge in its centralized placement. Perhaps the hinge contact points ar=
e=20
simply
like ball bearings?
 Has anybody seem the April issue of Popular Science magazine, where it
"hopefully" shows the seismometer"? If so, is it like the referenced
web page below?=20
 Take care, Meredith Lamb

Hi Larry= .
   With all the attention given to hurricane Katrina (and now= , increasingly of Ophelia
as it is battering the Carolinas) you may be i= nterested in my latest paper, titled
"Hurricanes and Earth hum"= ;, online at=20 http://arxiv.org/html/phy= sics/0509103
      The records for thi= s paper were taken with my 'modernized conventional
pendulum', some pict= ures of which are posted to this arxiv site.  The pendulum was
featured in the April issue of the Popular Science article titled "= ;Affordable
earthquake detector", concerned with last year's tsunam= i.
   Feel free to mention this research on the PSN mailing li= st if you so choose.
Thanks for your interest and best regards,
  Randall
