Ben, the shop vac will be pretty far away from the simulator when it's 
done - I may also isolate it in a muffle box of some kind.  The bypass box 
will be located next to the shop vac so you won't hear the bleed air 
either.  I'm going to try a 20' cable between the Arduino & the sensor 
port on the mirror to see how it goes.  I don't want to go too far or I 
risk killing the input channels on the Arduino due to line impedance.

I could also go the other way and have the bypass box near the mirror, but 
in a muffled housing that would damp out the sound.

Wayne's setup will have the advantage of piping the vacuum source through 
a wall (the shop vac will be in his garage) so he won't have to go to the 
extremes I will in order to muffle the noise.

The current setup requires nearly the full draw of the Fein Turbo III dust 
collector that I'm using and even with my 60gal air compressor going full 
tilt, I can't approach that amount of volume.  The Fein will pull a 105" 
water column which is roughly equivalent to about 8in HG.
