Digital electronics are all well and good, but it’s hard to ignore the organic, living qualities of the analog realm. It’s these circuits that Kelly Heaton spends her time with, building artistic creations that meld the fine arts with classic analog hardware to speak to the relationship between electronics and nature. During her talk at the 2019 Hackaday Superconference, Kelly shared the story of her journey toward what she calls Electronic Naturalism, and what the future might bring.

Kelly got her start like many in the maker scene. Hers was a journey that began by taking things apart, with the original Furby being a particular inspiration. After understanding the makeup of the device, she began to experiment, leading to the creation of the Reflection Loop sculpture in 2001, with the engineering assistance of Steven Grey. Featuring 400 reprogrammed Furbys, the device was just the beginning of Kelly’s artistic experimentation. With an interest in electronics that mimicked life, Kelly then moved on to the Tickle Me Elmo. Live Pelt (2003) put 64 of the shaking Muppets into a wearable coat, that no doubt became unnerving to wear for extended periods.

Wanting to create art with a strong relationship to organic processes, Kelly focused on working with discrete components and analog circuitry. Basic building blocks such as the astable multivibrator became key tools that were used in different combinations to produce the desired effects. Through chaining several oscillators together, along with analog sequencers, circuits could be created that mimicked the sound of crickets in a backyard, or a Carolina wren singing in a tree.

The work didn’t stop at a few sound effects, however. These circuits were woven into paintings, with individual components playing both a functional role and a visual role in the piece itself. What followed was a series of paintings featuring circuits to create the sounds of the animal depicted. Other projects were more sculptural, such as the transparent mylar constructions of Birds At My Feeder (2019), or the noisemaking worker bees of Pollination (2015). The electronics itself, from the oscillators to the analog sequencers used to drive them, becomes part of the artwork itself. Kelly refers to the hardware as beautiful, and it’s a feeling recognised by many who can recall their first time peering inside the mysterious innards of a disassembled radio or television set.

Coming from a fine arts background, rather than an electronic one, there was plenty of learning to be done along the way. Kelly spent plenty of time in the MIT Media Lab, picking up things at a fast pace as you’d expect at one of the world’s premier hacker universities. During the production of The Parallel Series (2012), Kelly realised she was struggling to keep track of how her experiments worked, leading to a note scrawled in the corner of one piece: “I need to document these circuits for my own sanity”. Any maker that’s come back to a mess of wires on a breadboard after a few weeks away can relate to this experience. Kelly’s process also developed over the years, becoming more analytical. The sounds of various creatures were analysed for pitch, timbre, and tempo, to help guide the work to recreate them in analog hardware.

Kelly’s work goes beyond simple analog oscillators. Through years of tinkering, she’s learned many tips and tricks to creating a pleasing and thought-provoking artwork. Repetitive sounds can be annoying, even if they are a decent facsimile of one of Mother Nature’s creations. To temper this, and add in a little realism, randomness is introduced into trigger circuits to make them sound more natural. Often achieved with something as simple as the base of a transistor left unconnected, when filtered, this can act as a great way to organically recreate the sound of a field of crickets chirping at each other in the night.

Much of the work is done on breadboards, making experimentation easy. As the components used are cheap and readily available, there’s little harm to be done, with the worst mistakes causing at maximum, a few dollars in damage. The stacking and reconfiguration of various analog oscillators in this work draws parallels to the world of modular synthesizers, a world we’re sure Kelly would also enjoy exploring.

Overall, it’s a great talk that covers the journey of creating artworks that blend the traditional and the electronic. Kelly’s art has been celebrated and displayed in a wide variety of locations, and it’s inspiring to get a look at the process behind the creations.
