That will be the next one I do.
No need for electronics, a wing stalls at 15 degrees, weight just changes the speed at which it stalls.
When the buzzzer goes off you are at fifteen degrees, it startles you,,,, you push and don't die.
KISS works.
Feelings about bureaucrats aside, I agree that you don't need any fancy electronics for a flapless plane, just wire the shaker and light to the contact switch on the vane or paddle AOA sensor, power it with a 9V battery, maybe add a "push to test" button to check the battery during your preflight, but how would you adjust for flaps up/down when a plane does have flaps?
