[Diy_efi] [Diy_efi]: prop sensing

[Stephen Andersen]

INteresting concept.  I would suspect it would require 
very high sample rates, and also would require some 
type of slip-ring to get the signals from the gauges
out.  The problem with slip-rings is that they can
be very noisy for a low-signal data acq. situation. 

Good ones could be pricy...
