Dick-

Sorry I do not have any information on the VolksMeter instrument, I 
am using old antique seismometers hooked-up to the Webtronics 
digitizer and it is working great.

I noticed that you were involved with instrumentation on Earth Tides 
at Sandia. I retired from Lawrence Livermore National Lab and worked 
with Sandia occasionally. I would be very interested in their Earth 
tides program if you know something about it or of a contact or any 
papers I could read.

I have attempted to make a sensitive tiltmeter based on an old 
article in Scientific American that was based on two-connected-cups 
of mercury and the signal was measured by changes of capacitance from 
plates just above the surface of the Hg. I was hoping to see Earth 
tides also, but it was not sensitive enough. If this is of any 
interest, check my website at http://gbush.mcn.org/ .

Thanks, and I wish you luck- George
