This is a project that's codenamed "Chung-On-A-Stick". It's meant to provide you with a "portable wind tunnel". We've achieved the first step, which is to make a sensor that can sense yaw and airspeed of the wind impinging on a bike. The sensor also broadcasts its data in ANT+ format, meaning that maybe one day your Garmin 500 will pick up its signal!
