Analog Electronic Crow /  by kelly heaton

The universe is made of energy, frequency, and vibration. Electricity is the Qi of life flowing through humans, birds, and circuits alike. My new "Analog Electronic Crow" (2022) is an evolution of Deep Fake Birdsong from 2020 in which I explore the power of electrically oscillating circuits to manifest intelligent behaviors. This circuit has only six oscillators: five astable multivibrators and one modified Hartley. It's battery operated so you can carry it around. Stay tuned for a product launch this Fall!

Printed Circuit Bird (Bluejay), 2022 /  by kelly heaton

My "printed circuit birds" are self-contained sound generators. The electronics are 💯 analog: no audio recordings or software are involved. By “analog” I mean that the sound is dynamically produced by the bird’s body (circuit), like a vintage synthesizer. In this video, I adjust knobs to change resistance in the circuit, thereby altering the song quality. You can think of this like adjusting neurons in a bird’s brain to alter the impulse by which it vocalizes. I am passionate about building circuits because they demonstrate the life-like qualities of electronic hardware, which is often over-looked in favor of software. I’m not sure why we abandoned analog hardware along the road to technological advancement— digital is great for what it does, but it’s not the full spectrum of creative electronics. It would require a vast amount of hardware to build a digital computer capable to execute code for birdsong like this.

Circuit Garden celebrates our electronic culture and invites us to contemplate nature – specifically human nature in symbiosis with machine intelligence. Artist Kelly Heaton presents a large-scale circuit board in the form of an artificial lawn that is “planted” with plush sculptural electronic devices. The work evokes a playful garden, or a vintage circuit board that has been enlarged to human scale. Situated in the landscape of Circuit Garden, viewers will discover smaller functional circuits that mimic animal behaviors, such as birdsong and chirping crickets. As the viewer approaches the installation to investigate further, Heaton’s analog electronic designs generate these naturalistic sounds in real time.  The sonic landscape of Circuit Gardenis thus brought to life by electric vibrations of artificial origin and not recordings of real birds and crickets, as one might expect.

 STATEMENT BY KELLY HEATON: 

“Electronic technology is profoundly shaping our world. Many people are symbiotic with their smart phones and digital presence. Artificial intelligence is growing smarter, and our concept of “nature” is being radically transformed by engineering.  Electricity is the most important invention since the discovery of fire. Yet, the art of electrical engineering is not well understood or practiced by people outside of the scientific community. I would like to invite everyone—not only engineers—into a conversation about electronic culture, nature, and the rise of machine intelligence. While most artists work with digital media, I focus my creative practice on electronic hardware because circuits are the physical body without which there would be no digital media. Like a biologist studies animals, I study circuits to understand the physiology of intelligent machines. I am inspired by Nikola Tesla’s statement, “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” My art explores these concepts literally in the form of circuits that vibrate in naturalistic patterns. Circuit Garden pays homage to electrical oscillation, specifically to the astable multivibrator, which is my favorite method to generate life-like waveforms.”

Printed Circuit Bird, 2021 /  by kelly heaton

Printed circuit bird, 2021. I created this work of electronic art to demonstrate the principles by which consciousness originates. The bird's circuitry is entirely analog electronic, which means that her song is not recorded but *generated* by adjustable vibrations in the circuit that forms her body. She is designed to vibrate when exposed to electricity, and we hear the resulting (audible) waveforms as a bird-like sound. Her circuit contains five analog electronic oscillators that are coupled together with a combination of resistors and capacitors. The vibrations of one oscillator affect the others, thus causing a degree of complexity and unpredictability that we wouldn't expect from such a simple circuit. It would be difficult to model this analog system because there are so many possible states, as I will attempt to explain below.

In the video, you see me adjusting variable resistors that affect the frequency, amplitude, and symmetry of the oscillations. The resulting changes in vibration are heard as tonal variation and patterns of sound, or "syntax" of the bird's song. In other words, we can hear the frequency, amplitude, and temporal structure of the waveform as it changes within the bird's circuit. Residual capacitance adds to the unpredictable nature of cause and effect. It is not only which knob I turn or how much, but *when* I make the adjustment relative to the state of the entire connected circuit. These are the continuous, interconnected, analog principles from which life-like behaviors arise. The late roboticist and neuroscientist William Grey Walter experimented with similar principles, notably demonstrated by his tortoise robots.
She is like us — we are electrical beings, too. The neural activity of a human brain is an aggregate of billions of oscillating neurons affecting each other to form thoughts and feelings. While each individual neuron is very simple, the complexity of the neural system is unfathomable. As Nikola Tesla said, "If you want to find the secrets of the universe, think in terms of energy, frequency and vibration." These physical laws are the basis of mind and our conscious universe.

Acrylic, copper etching, silkscreen, and custom analog electronics on fiberglass panel (aka manufactured printed circuit board). 24” x 18” x 1.5” The squawking sounds rare generated by the analog electronic circuit that surrounds the birds. In other words, electricity is flowing through the surface of the painting.

Pretty Bird ver. CC 2019 /  by kelly heaton

Here it is at last: my edition of 150 printed circuit boards and associated components, “Pretty Bird ver. CC,” 2019. This multiple was commissioned by Creative Capital for their 20th summer retreat celebration. I designed the artistic circuit using discrete hardware to generate waveforms from a 12 volt DC power supply, visible as blinking LEDs and audible through an 8 ohm speaker. Under the right lighting conditions, the sound is reminiscent of “pretty bird,” a song of the Carolia wren. There are no audio recordings or software algorithms involved in this effect — it’s entirely analog electronic. In the upper left corner of the circuit is a light-dependent resistor that affects the frequency of a negator oscillator, as I demonstrate in the video by changing the ambient light. It’s fascinating to me that a small quantity of common transistors, resistors, capacitors, and diodes can create vibrations that are so life-like. Similarity or simulacrum? The spark of life.
