Hi Jan,

Nice construction!  Thanks for all the photos!

Have to agree with Chris about the magnet and coil...it would
generate less "noise" if they were reversed to where the magnet
is on the base, and the coil is on the boom. One could even use
say.....fine enameled magnet wire hanging down from higher up
on the mast and loosely draping onto the boom and its coil
connection.....or "looped" (gives it room to flex) over the top
of the mast and going down your suspension mechanism.  I'd
guess over 70% of the displayed seismogram "noise" would
disappear if done in this enhancement fashion.

Take care, Meredith
