Dual Light-Controlled Voltage Source

SetonixSynth x Tidbit Audio Solar Voltages

The Solar Voltages is a 2hp, 2-channel Solar Cell module which outputs two separate control voltages in response to light. Each channel outputs approximately 0-5V, with higher voltages corresponding to more intense and/or direct light. As the two channels can be manipulated with relative independence, the Solar Voltages makes for a great low-profile and multi-dimensional “light theremin” for direct and spontaneous control of two different parameters at once.
