Diy police siren replica

       So I was trying to make a simple police siren on a breadboard using no semiconductors. Anyways, the question that determines whether or not it can be done using only one semiconductor (a diode) depends on this question. Can an Esaki oscillator work using a reverse biased diode instead of a transistor.

    If the project works out I might end up making an instructable about it. Would you like to see it? Please comment below.

I don't think so and if you use tunnel diodes they will die sooner than you can the sound.
