Documentation of “Circuit Bird,” 2021, an adjustable analog electronic circuit for birdsong generation. The art is made with custom electronic hardware, printed circuit boards, foiled chipboard, and screen-printed silk laminated on a wooden frame. Dimensions are 35” tall by 23.5” wide by 1.5” deep. Watch the video to hear the circuit vibrate with birdsong. Notice the modular components of the circuit: I separated the oscillators, the passive coupling filters, and the audio amplifier into separate (but connected) printed circuit boards. This design enables me to assemble different quantities and configurations of oscillators to create new artworks based on the principle of vibration.
