Airspeed Indicator

It doesn’t look like much yet, but this will be an airspeed indicator. I am following the design ideas in Mike Powell’s book.

Here I have colored the motor deck (3.24″ square) with blue Sharpie and laid out the center lines for the holes.

Below are the faceplate and the motor deck, both 0.064″ aluminum. The 1.8 stepper motor was salvaged from an old HP Scanjet 5100.
