 One-sided PCB is traced with Toporouter for prototype only.

A smaller two-sided PCB is planned after testing the prototype.

Youtube video shows a very early prototype implemented on Arduino using 20x4 character LCD.

Test signal is generated with Matlab (background music is not used as a signal).
