Great write-up, Solarbird (below). We are thinking same-same regarding resonator elements for a neo-crystal mic. Very soon we will publish a new instructable on building the Hula Mic: a crystal mic built from bungee cords, binder clips, a hula hoop and a clock face — and of course a Cortado contact mic. A companion article will detail our own research, which led to similar conclusions: the performance of the resonator depends on not only its mass, but its density and rigidity. Guess what material wins that contest?
Here’s a sneak peek.
