Jay,

Well I just got it working last night and it ROCKS!!!!

However, don=B9t get too excited.   The cost of this baby is way out of site
(probably $1500).

It is complex and the cost of the parts alone is $400, let alone the labor
to build it.

Still, the performance is out of this world.  This thing has a noise and
jitter of under 1/1000 volt!  And that is on one of those bread boards.
Mechanically is feels great.  Recentering repeatability is about 1%.
Tastes great, too.  ;-)

Considering the working hours I've=
