Why not just use a nice, simple reed stall warning?
That's certainly a possible solution but I suspect that getting the aperture size and angle just right is harder that it looks.

Can't be too difficult, Cessna managed to do it.
Well thanks alot! now there goes all my hope!! just kidden:gig:
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?
That's what we are all here for, isn't it? To learn to speak "Airplane", or to teach it to others.
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.
I sure hope you're receiving royalties from Google.
