This thread will show my construction of an airspeed indicator using the techniques in Mike Powell's book.
So far I have the faceplate and motor deck constructed from 0.064" aluminum.
The motor was salvaged from an old HP Scanjet flatbed scanner, it is a nice little 1.8° stepper.
I hope the pictures work, I am using Facebook to save my poor home DSL connection.

My wife was totally unimpressed, but maybe somebody here will appreciate what I am trying to do. :)
