The 6x6cm semi-transparent photovoltaic glass harvests 3-5V under direct sunlight, powering a starvation synth—a deliberately low-power circuit that generates organic, non-linear noise through capacitor value manipulation. Features dual audio outputs: one for synthesized noise and one for raw DSSC signal. Handcrafted in a home laboratory using W-type series configuration, this artistic photovoltaic device functions as both functional noise generator for modular systems and conceptual sculpture. Performance and lifespan vary naturally (typically months to years) due to its experimental, handmade nature.
