Hi all

I have finised the basic lehman type seismemter build. A picture of it
can be seen here,

What currently is missing is decent magnetic damping and a decent mass.
But I also would like a opinion on this design that I am using.

The plot from this seismoeter can be seen on my webpage.

Regards.
