[simpits-tech] Viperpit.org SSC project a success.

[Marv De Beque]

Tis the beauty of "Male Answer Syndrome".  You simply cry that you are
disabled.  :-)

I did not really look at your final design, but I did remember you had an
idea using a bending beam as the main spring system and a secondary beam
that amplified the amount of movement at the LVDT slug.  Did you choose that
design?

Also, did you take repeatability measurements to see if the beam returns to
center reliably?  You remember all of those headaches I went through.  :-)
