My Feedback: (1)

I know a lot of telemetry options already exist for this, but I like to tinker with electronics. The circuit on the left, powered by 5v from the receiver battery, transmits airspeed. The circuit on the right (which I need to 3d print case with belt clip) receives the airspeed value. It also receives a value from a potentiometer. It then sends 2 tones to the headset; one left and one right. One being the reference tone and the other being the actual airspeed. There are also volume potentiometers for both. Used as an example, to set approach speed. When speed reaches the approach speed both tones are the same. If the speed drops below the reference speed the tone duration also changes.

I don't know if will be all that useful. I have never had a problem with speed but it was something I wanted to play with.
