## Printed Circuit Bird #Art #Electronics @kelly_heaton

Artist Kelly Heaton demonstrates a printed circuit bird. She is entirely analog electronic, with five oscillators (with adjustable resistance) combining to generate different patterns of song.

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.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
