Mr. Gerrey, things have indeed changed since your excellent research on
wlwctronic clicks. I suggest that you renew your interest in the matter,
at least to the point of producing a prototype with a couple of knobs
that allows for selecting different pitches, and different pulse
lengths.
It just might be that there could be some agreement on optimum values for
these parameters, and that a itsy-bitsy unit (without potentiometers,)
could be built that would fit right into the handle of a cane. What do
you think about that?
