here comes the sun
i want to introduce two new autonomous circuits i have built and added to my e-beastiary. the circuits are variations based on the solarsoundmodul by Ralf Schreiber. the critters are photovoric singers that employ a Schmitt Hex Inverter IC, resistors, capacitors, piezo buzzers, and a photovoltaic cell. the modulation is slightly different on each output pin from the varied combination of capacitance and resistance. they range from creacking to screaming, lilting to terse. the lovely thing is that they change as the environment changes, of course chief is the angle of the sun to the solar cell, but unexpectedly and pleasing are other variables like movement, wind, fluttering leaves and branches which all effect the output. this produces a direct response to the environment reinforcing the autonomy of the critter.
my next goal is to embed them into the landscape. i have a fortunate opportunity that my current employment site is in the middle of a nature preserve. to be continued...
