[EXPERIMENTAL]

Sketches

NB10d0.jpg
Initial concept, momentary switch not shown, idea to use 4 alternating LEDs to represent 1010 binary version of "10". 3 peaked resistor as symbolism of bay bridge.


NB10d1.jpg
Full bridge rectifier of LEDs with speaker as DC load and AC input. By varying the frequency different tones/noise is generated. Image should be vertically flipped.


NB10d2.jpg
Positioning of components and traces to more visually illustrate a 10.


Prototype

LiteON LTL911TGKS green LEDs soldered together in rectifier configuration with 8Ω dc speaker load and ~5v rms ac ~20hz-20khz.
