As I see it, Expeyes has a minimal role to play. The experiment needs 3
modules
1. a tunable sine-wave oscillator or signal generator.
2. audio power amplifier and
3. electro-acoustic device to drive the plate (speaker or vibrator)
Expeyes can only be used in the first module and that is as an elementary
signal generator. Maybe if we can add a frequency sweep in the python code,
it might be easier to tune the frequency for sharp resonance.
Again i would be happy to have some explanation about how an impulse
generator can be used. I am afraid it might excite multiple harmonics
simultaneously which could mask out individual patterns. I think a pure
tone would be better, but I could be wrong.

Are there more details regarding the set up?

Hello all,
I want to share one idea of an intersting experiment. The theory behind
it is very serious, but experiment is attractive and intersting.
It unlocks potentional of expeyes but on other side some additional work
and material is needed.
I will give the idea which is not mine, on youtube video link below, and
you could see what is all about, and what one needs to make it in own
conditions. That is so called Chladini plate, but I have tried something
similiar with no big success something like drums and in side it a speaker
connected to impuls generator.
And the link finally:
