Subject: Interesting sensor pickup.

On my Lehman sensor I have been using a homemade coil that provided moderate
output. I seem to have stumbled across something that works even better.
From an old (dead) hard drive,  I pulled the head positioning component and
gave it a try. I drew up a (bad) picture of the piece I am talking about. It
can be viewed at .
I rigged up a linkage to the seismo and gave it a slow 1"/sec swing. I got
an output of 0.026 V. the coil has a DC resistance of 18.1 Ohms.

Anybody else tried a setup like this?
