JNorton,

I've often wished I had a stall warning horn and what you said about pressure sensors and your engineering skills has me wondering if I can get you to build it. I've seen small solid-state devices that emit a loud tone. If you could mount one in the plane and arrange for it to sound off when airspeed is below some setting (derived empirically?) it would make landing a lot less intimidating. Maybe even have two tones, one sounds off when you get down to a good approach speed and one just before stall.

You can probably guess from my handle that this is a problem for me.

If you could design a circuit, I would be willing to try to build it. What do you think?
