Choosing nice easy start

As Teensy board is on its way is time for more planning. Im definitely creating an universal not 100% alike Cessna 182 cockpit. As a first cockpit instrument I want something easy, one way system. I think airspeed gauge would be a good start. Looks like all I need is a X-Plane writing to serial port using X-Plane's data refs reference: 

Sim/cockpit2/gauges/indicators/airspeed kts pilot

For more data refs out references look here: http://www.xsquawkbox.net/xpsdk/docs/DataRefs.html

Following this design for a gauge backplate. Looks like need simple servo motor to map angle from date passed by X-Plane

Another great news! Ive bought 3d printer with three of my friends so manufacturing parts will be possible. At the moment we are printing some upgrade parts for a printer itself.
