Hi all,

I put up a web page of Dr. Randall Peters magnetic axis/pivot thought and
that of Chris
Chapmans crossed cylinders/rods pivot suggested idea.

The magnet/s involved are those from Forcefield.com, and are of the polarity
where
the poles are through the rod diameter; and not at the ends of the rod;
which is much
more common.

All in all, it really seems initally VERY interesting, from what little I've
seen.  The web
page will text more observations and possiblities.  One main point is that
it appears
that the mass weight can possibly exceed over 1.5 pounds...and the boom
length for
the natural period could be easily lengthened.   I'd think it would best
serve along the
"hanging mass" orientation for a horizontal sensing unit; but, it could also
be possible
to lessen the mass weight to accomodate a vertical sensing unit.
