Hey goldsmi - how's Rochester, did you get the typical easter blizzard we always seem to get graced with

?
Didn't you work at Xerox too? If so, do you know Marty Pepe? He was the ROS engineer on Lakes, he's probably on Aldebaran or Constellation now.
Anyway - if you do know him, it would be neat to use his acceleromter crash cart to see just how much and at what freq's the DMD is damping. It's a cinch to do - a couple of probes and push a few buttons, you get an instant FFT of the freq's and amplitudes it's seeing. I spose not much point if you already have it on the car as you'd want before and after, but if you don't have it on yet you could do a quick before and after scan with probes on the subframe to see how much vibes are reduced to the frame. Maybe see if he has his acoustic probes too to see if there is more damping of physical vibes or noise.
