@BuildSomethingUseful Stack must be fine and loose. Does not run with one LED! You have to use two LEDS (3V,75mW)! LEDs must be red hight bright!
I tried three different sizes piezo elements but it run only with small sized piezo. I put piezo where I can't overpower sound but vibrates good wall in resonator tank. Piezo is glued on bottom of tank wall. Tank is to be prolonged that engine is not be loud (is closed).
