In a previous post I had mused that the Volksmeter electronics might be 
retrofitted to a Shackleford-Gundersen type assembly.  I'm not sure there 
would be any great benefit, but variety is the spice of life...     Well, 
surfing this morning, it would seem that someone in Austria did exactly 
that.  Here is the link:

It looks like a fairly easy setup, but some things I noticed - 1) they have 
not seemed to insulate against air currents as much as others with a true SG 
sensor.  2) they are using active damping like an SG using data from the 
AD7745.

Any comments?
