Moth Electrolier / June 25, 2022 by kelly heaton

New footage of my Moth Electrolier from 2019

In this sculpture, analog electronic circuits generate patterns of animated light that mimic the flight trails of moths around a bulb. The circuits are made with a series of oscillators connected together to form pseudorandom patterns, and these patterns are used to clock shift registers. This is why the animation occasionally "flutters" before continuing along the sequential trail. The wings of the moths are dyed velvet that were embroidered with an old industrial machine according custom CAD files. The translucent plastic sphere is laser cut acrylic that was heated and shaped into spiral patterns. The sculpture attempts to depict living nature in all of its magical, electrical movement as well as its delicate fragility. As electronic technology increasingly shapes our built environment, it is harder to distinguish between biological and machine intelligence. The construction of circuits that mimic life-like behaviors is part of my "electronic naturalism" practice to demonstrate just how similar circuits and living organisms can be -- without any code or recording to inform the behavior, just the physical assembly of electronic devices that vibrate when exposed to voltage. This and several other sculptures from the same time period (Birds at My Feeder and Electrolier (Summer Night)) were created during the same time as I published my Hackaday project, "Hacking Nature's Musicians." A diary with process images and associated schematics can be found on the following pages:

Moth Electrolier and Birds at My Feeder are a celebration (and demonstration) of the open source hardware and Makerspace movements that were happening around this time in history. I used various unusual techniques to create these works, including an old embroidery machine, laser cutter, thermoformer, Blender (open source 3D modeling software), and a bricolage of electronic hardware techniques from my earliest foray into printed circuit board design. I would like to thank NovaLabs Makerspace (formerly in Reston, VA) for the various equipment and education that I used to make sculptures during this time.

Pretty bird / March 11, 2019 by kelly heaton

A sculptural bird circuit that sings “pretty bird” when the ambient light conditions are favorable. The exterior is folded Mylar and the interior is an analog electronic chirp generator soldered freeform. This part is part of a larger work in progress.

Above: images of the freeform chirping circuit (stabilized to Mylar using glue) prior to insertion into the bird’s body.

+ Electrolier Virginia + packing for Mexico / October 21, 2018 by kelly heaton

It’s been a marathon recently… just finished “Electrolier (September night in Virginia),” submitted by files for the 2018 Hackaday Prize, and now I’m packing for Mexico. Stay tuned for updates from the jungle of Quintana Roo!

Electrolier (September night in Virginia) / October 20, 2018 by kelly heaton

I've been working around the clock to finish my Hackaday Prize application and pack for Hacking Nature's Musicians in Mexico. As closure for my recent chapter, the various circuits that I've shown you over the past few weeks have migrated from my bench and into a sculpture titled "Electrolier (September night in Virginia)," 2018. Here is an informal video:

The video quality isn't great... (shot with my iPhone under bad lighting and extremely messy studio)... but hopefully you get the idea. The sculpture contains one instance of my Mother Nature board design, recognizable by the dense tangle of white wires connecting logic gates, and six sound generating "animal circuits" each with its own speaker. The colorful graphics are spray painted cardboard, and everything is hung on a tree structure under a moon (globe pendant bulb). Oh, and that large moth is made out of silk velvet that I dyed and embroidered with an old industrial "Ultramatic" machine. I would have used small molex-style connectors to connect everything, but there was no time.

It's interesting that so many long wires didn't screw up my signals. I credit this to my use of common emitter amplifiers to buffer the signals, and the fact that I'm not drawing much current for anything you see (or hear). The whole sculpture is powered with a 12VDC / 1.5 amp power supply. I also used multiple 0.1 uF ceramic capacitors between power and ground on most of the individual perfboards. It's critical to remember power-ground capacitors when you're dealing with a lot of amplified signals banging on your power rails. I'm careful to avoid really small gauge wire, and I add many pathways to ground ("let ground abound.")

So... now I am packing my electronics bench into a suitcase and praying that security does not detain me at the airport. I'm throwing in packets of desiccant and crossing my fingers that jungle humidity doesn't zap everything. Making analog electronic circuits in the jungle will be interesting to say the least -- stay tuned for the sounds of los músicos de la naturaleza en Quintana Roo!

August insects / August 14, 2018 by kelly heaton

Landscape painting and analog electronic soundscape (detail of work in-progress). August 2018

I create the sound of a buzzy August insect using a 555 timer to drive a transistor astable multivibrator (to give timbre). Another slow astable multivibrator provides pulse input to a 555 timer in monostable configuration, that gives a pulse out to the base resistor of an astable multivibrator that sets the tempo. That's why the insect rattles for awhile and then stops (monostable 555 goes high - the rattle tempo is active low).

wild card: the great stalacpipe organ / June 5, 2014 by kelly heaton

This is the first ever composition for The Great Stalacpipe Organ, the largest musical instrument in the world, located deep in the caverns of Luray, Virginia. The Organ consists of hand-tuned ancient stalactites of varying sizes that are hit with solenoid-actuated rubber mallets. The mallets are controlled by a custom made pipe organ console.

Leland W. Sprinkle designed and implemented the organ during a 3-year period around 1956.
From Wikipedia:

"Two accounts of Sprinkle's conception of the instrument are known. From the discovery of Luray Caverns in 1878 onward, the favorable attributes of the formations for creating musical tones were well known. One of the earliest references to performances of lithophone music in Luray Caverns comes from the tour led by co-discoverer Andrew Campbell for a group sent by the Smithsonian Institution in 1880. According to a summary of the report incorporated into the earliest printed guides to Luray Caverns, Campbell surprised the group by playing a tune on a formation, probably the one that came to be known as the Organ. By the early 20th century, performances of folk tunes, hymns, and other well-known pieces were a regular part of guided tours. According to the modern guided tour, Sprinkle is said to have conceived the idea for the Great Stalacpipe Organ during one of these performances when he toured Luray Caverns on his son's birthday in 1954.

A variation of the story of the instrument's conception is that Sprinkle's son Robert hit his head on a stalactite, producing a tone that inspired Sprinkle to invent the instrument. This account is the one published in a Meccano Magazine article from 1961 and in an article in the 1959 Rosicrucian Digest."
