Volume I: Light For this circuit, two photoresistors and a C74C14 chip turn light into sound. Very subtle gestures and movements that cast shadows upon the photoresistors can produce wavering and harmonic oscillations. When this circuit detects bright sunlight it’s pitches are incredibly high – beyond the range of human hearing. When shadows are cast upon this circuit, its tones enter the realm of human hearing and turn movement and light into twinkling sequences of analog enlightenment.

Volume II: PulseBuilt with a CD4093 chip, this circuit drives two oscillators that may be controlled in terms of pitch, tempo, and volume. This synth can generate a full spectrum of flanging drones, phasing polyrhythms, and rhythmic pulses. Meant to be played, and performed with, this synth is intended for use in the exploration of the otherworldly sonic worlds. Touch, twist, and modulate the invisible waves that surround you.

Volume III: TouchBased upon two LM386N chips, this circuit generates beautiful oscillating white noise that responds to atmospheric electromagnetic waves. This circuit is the unique result of experiments with white noise, feedback, and skin capacitance. When touched, conductive pads diffuse electricity through the skin to create a palette of “fierce” sounds. Applying full pressure to both pads shorts the circuit. However, by applying very delicate pressure, this circuit produces harmonic sirens, fierce bobcat tones, and polyrhythmic clicks and pulses. To generate a variety of sounds it is necessary to apply the most subtle touch, just the right amount of energy…
