Transformation Process 

of Time Machine

Sacrificial Mind, 2019

After five months studying abroad at the Chelsea College of Arts in London, I came back to Chicago in early 2019 and reunited with my works. The Phenomenal experience of Genesis Trilogy began to manifest in multiple ways. First, I completely transformed Time Machine by burning it. A sacred ritual for Time Machine was necessary to follow up with new discovery of my identity. Then, I simplified the system by removing unnecessary features and customizing PCB with upgraded microcontrollers and circuits. It was part of the process prioritizing the aesthetic.


Some of transformations were made by accidents. For example, the air outlet of the compressor got a tiny crack by over tightening which caused a constant air leak. This changed the whole dynamics of the performance. Now the sound of inflation caused unpredictable pattern during the symphony. Interestingly, however, Time Machine became much more alive than before.

I charred all the wood surfaces, and stained with red. Then, I applied clear lacquer. After dried, I sanded the surface and applied wax to buff and shine.

For metal surfaces, I plated with either brass or iron, then applied different patinas to achieve layers of natural aging color. Also, I powder coated most of hardware.

I accidentally shorted the circuit inside the pendulum which completely burned the whole components. So I replaced them with an upgraded system.


I switched Arduino Uno to Nano, and customized PBC by using Fritzing and milling machine. Also, I switched flimsy wires to JST SM connectors to improve stability and convenience.

For Primal Heart, I changed the color of LED and metal surfaces. In addition, I simplified the internal circuits by removing the feedback system which included pairs of amps, speakers and piezo microphones.

Then, I placed one of the feedback systems inside the pendulum. I attached a piezo microphone onto the solenoid and amplified the noise within the Time Space. Here, I was calibrating to find the proper frequency.
