Hi everyone..i am new to this forum and by profession i am a hardware design engineer. Actually i recently started to build a DIY aircraft. Then i found this forum. I want to know about that DIY stall warning system. What is it and how it works? How i can use it? What are its various specifications and cost estimate?

I've been considering the manufacture and FAA approval of a vane type AoA indicator for certified airplanes. Turns out that getting it out of the propeller blast is as much trouble as making the unit.

It is usually a small spring-loaded tab that is normally air-loaded to the "down" position in cruise but when the airflow into the wing begins to come from underneath, i.e, a stall airspeed, it moves the vane up and triggers a horn in the cockpit. It doesn't have to be a vane, though.

See stall warning vane - Google Search

I apologize in advance if my suggestion is deemed offensive. :)

Good description, but not at stall speed, rather at stall AoA.
