Circuit Garden contains a sculptural “integrated circuit” (IC) that is open to reveal the inner life of electronic devices. The circuit inside of the IC depicts an ancient archetype: the Tree of Life. I was specifically inspired by Buddhist Thangka painting, which shows us that we are all connected in a universal system. Spiritual enlightenment beckons us to see through the illusion of separateness and discover that we are all facets of the same source energy: the many faces of God, the branches of one cosmic tree. The universe is a circuit, and we are its electronic components.

In our world of everyday technology, integrated circuits are the ubiquitous “chips” that empower civilization with machine intelligence. Nearly all ICs look like black bugs on the outside, meanwhile their magic and uniqueness is hidden within this exoskeleton. If we open an IC, we are faced with a highly miniaturized circuit for which we need a powerful microscope to observe; but even with a microscope, chips are so staggeringly complex (and often proprietary) that the majority of humankind is oblivious to their anatomy. ICs are formidable “black boxes” of civilization-altering technology that is hidden from view. In fact, circuits of all types are customarily hidden from view… which makes me want to see them even more!

I do not want to put my electronics in a black box; I want to demystify and use electronics for contemporary artistic expression. While most processors are incredibly complex, the design principles and functionality derives from relatively few types of components with behaviors that we can understand, such as transistors, resistors, capacitors, diodes, and inductors. Circuit Garden invites people of all backgrounds to ponder the nature and magic of electricity as a medium by presenting some of the most common electronic components in a large-scale, simple format.

Circuit Garden (2022) is inhabited by analog electronic sound-generating circuits in the form of birds and crickets. The sound made by these individual circuits is self-contained (generated by the circuit itself); however, their audibility is orchestrated by an Arduino-controlled panel of 11 relay switches. These relay switches are connected to the speaker wire of each bird and cricket.* Simply put: when a relay switch is on, the bird sings; and when it is off, the bird is silent (even though the circuit is still actively generating sound, we hear nothing because its speaker is not enabled). The reason that orchestration is so important to the soundscape of Circuit Garden is that it would be unpleasant for the circuits to make sound all of the time. With orchestration, the soundscape of Circuit Garden seems natural (i.e. it seems like what we expect from “nature”). *Circuit Garden contains two notable exceptions which are the Kakapo and Goose that laid the golden egg (which I will discuss in a separate post). These birds have their own, dedicated motion detectors.

Most of my current generation of bird and cricket circuits do not contain motion detectors or awareness of each other — they only generate sound. Of course, I could add awareness and sequencing to each and every circuit, but this requires significantly more electronic parts and higher cost per unit. My priority for Circuit Garden was to highlight the life-like nature of analog electronic sound generation. For this reason, I decided to consolidate the task of orchestration (sequencing) to a single “Tree of Life” circuit that connects to each of the elements via wires that run beneath the grassy platform. To do this required a lot of wiring, as shown in the partial diagram below.

Another notable feature of my Tree of Life PCB is a miniature re-creation of the entire Circuit Garden composition (see image below this paragraph). If you look at the base of the Tree of Life, beneath Buddha, you will find a simple circuit that blinks two yellow LEDs — same as the large, sculptural LEDs that blink in the center of Circuit Garden. Here, in this little circuit, you can find the functionally electronic counterparts for every sculptural element of Circuit Garden. The formal composition of the installation is an astable multivibrator; my bird and cricket sound circuits are systems of astable multivibrators. This classic circuit design was invented by Henri Abraham and Eugene Bloch during World War I (source: Wikipedia). It contains only a handful of discrete electronic components: two transistors, two capacitors, four resistors, and two LEDs (which are not necessary to generate the signal vibration, but needed if you want to see it). I love the astable multivibrator as a symbol for life because everything in the universe is comprised of myriad interwoven vibrations. As Nikola Tesla said, “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” Similarly, the third Hermetic principle states that “Nothing rests; everything moves; everything vibrates.”

As above, so below.

My Tree of Life circuit is an electronic rendering of ancient culture merging with contemporary in a continuum, wherein electricity and spirituality are the common threads. My choice of the Tree of Life motif is due to the similarity of function and meaning: all creatures on Earth are sustained by a tree of life that connects and sustains us in an ecosystem. Electricity flows through all things and gives life. The bodhisattva in the tree of life are alternately switching in-and-out of “enlightened” states as they evolve towards an understanding of the great, universal circuit in which all life is connected as one.
