2003, 16.5"W x 7.75"H x 6.5"D
DC relays, digital electronics, MDF (110 VAC, 60 Hz)
The two relays chatter at each other, reprising the Abbott & Costello, "Who's On First?" routine in morse code. It take about 32 minutes to complete, at which point the machine turns itself off (it may be switched off at any time by pressing the front button).
2003, 11.375"W x 9.75"H x 11.375"D
DC relays, digital electronics, MDF (110/220 VAC, 50/60 Hz)
The 5-Way Metronomicon emits a varying rhythmic series of clicks lasting 1 - 5 seconds. The emissions are separated by random periods ranging from a few seconds to five minutes. Runs continuously, but may be switched off at any time by pressing the button on the rear.
2001, 20.375"W x 7.5"H x 20.375"D
Dominoes, solenoids, digital electronics, MDF (110 VAC, 60 Hz)
Pressing the button on Ouroborus causes one of the dominoes to fall over, knocking over its neighbor, triggering the familiar cascade. After roughly half have fallen, the dominoes begin standing up again, resulting in two waves of dominoes falling and rising. The Ouroborus stops after five cycles, with all dominoes standing.
2nd place winner, 2004 Kinetic-Art.org International Kinetic Art Competition.
2002, 17"W x 17"H x 4"D
Carbon fiber rod and strip, servos, digital electronics, MDF (110/220 VAC, 50/60 Hz)
Every 5 minutes, one of the 9 strips rotates to a new position, in increments of 45 degrees, as the machine "draws" a new design. Hence, each design takes 45 minutes to draw and lasts for 5 minutes, when the next design begins. There are 25 distinct designs, requiring 18.75 hours to progress through all, though the machine turns itself off after 8 hours; it remembers its last configuration, however, and starts from there the next time it's turned on. The machine may be switched off at any time by pressing the button on the bottom.
2003, 7.25"W x 13.5"H x 7.25"D
AC counters, digital electronics, MDF (110 VAC, 60 Hz)
The counters display four consecutive prime numbers. Every five minutes, one of the counters advances to the next prime number following the one it is displaying. At power on there is only a one-second delay between each increment, to allow easy verification that all counters are working. The piece runs continuously until the rear power switch is pressed.
2002, 16.5"W x 40"H x 4"D
DC relays, digital electronics, aluminum box and frame, masonite (110/220 VAC, 50/60 Hz)
After a brief series of coordinated clicks at power-up (which is repeated every hour), each relay individually clicks (separated by delays of several seconds to several minutes) according to a separate program, causing their increments to overlap in irregular ways. Runs continuously or until switched off.
2003, 4.5"W x 96"H x 5.5"D
DC counters, digital electronics, aluminum box, steel tube, MDF (110/220 VAC, 50/60 Hz)
All the counters display a prime number. Every 5 minutes (every 5 seconds at power-on), one of the counters increments to the next prime number following the one it's displaying. Runs continuously or until rear button is pressed.
2002, 35"W x 75"H x 7"D
DC counters, digital electronics, aluminum box, coax (110/220 VAC, 50/60 Hz)
Each counter is incremented according to a program unique to that counter, resulting in a click or series of clicks every few seconds to every few minutes. Because the programs are uncoordinated they periodically overlap, resulting in one or more counters incrementing in semi-unison at random intervals. Runs continuously or until switched off.
2002, 23.25"W x 7.25"H x 5.5"D
AC motor, aluminum strips and frame, wooden spoon, steel scouring pads, masonite (110 VAC, 60 Hz)
Rotary motion of the motor is translated into reciprocating motion of the spoon, into and out of 2 steel scouring pads (~5 cycles/minute). Runs continuously or until side button is pressed.
2003, 10'W x 9'H x 1'D.
The Metronomicon was to consist of a 7' x 7' array of 616 identical electromechanical relays operated by approximately 30 embedded microcontrollers, configured as a programmable musical (percussion) instrument.
2005, 62.25"L x 33.5"W x 16"H
10,240 LEDs, digital electronics, acrylic, MDF, aluminum (110/220 VAC, 60/50 Hz)
Simulates nuclear fission via animated LEDs.
2006, 8'W x 6'H x 2'D
Aluminum, brass, steel gears, electric motor, halogen lights.
Kinectronica was commissioned by Power Integrations (San Jose, CA), a manufacturer of components for electronic power supplies. They wanted a mechanical representation of a power supply, and Kinectronica is the result. It comprises more than 600 moving pieces in 11 subsystems that accurately (though metaphorically) model corresponding subsystems in an actual power supply.
2012, 15"W x 10"H x 4"D
Aluminum, MDF, Lexan, tungsten, iPod, electronics (110/220 VAC, 50/60 Hz)
Elemental #1 is based on the principle of the plasma speaker. An electrical arc of several thousand volts spans the gap between two electrodes and is modulated with the audio from the iPod. As a result, sound emanates magically from the arc.
2007, 12"W x 12.5"H x 5"D
Aluminum, DC motor, batteries, bearings, resin figure, high-density foam.
The motor turns a cam which alternately displaces and release a spring-loaded pivot bearing a miniature bust of Michaelangelo's David, causing the bust to retreat from, and then smash into, a piece of foam.
2013, 4"W x 4.625"H x 2.5"D
MDF, intelligent LCD touch-sensitive display, 110/220 VAC, 50/60 Hz
GIFerator displays a series of animated GIFs (short, silent, looping videos), each for a couple of minutes before advancing to the next. The user may force an advance, load the previous GIF, make the piece go to sleep, or wake it up, by tapping various places on the screen.
Animated GIFs are usually only viewable on a personal computer, smart phone, or tablet. GIFerator liberates them.
2013, 4"W x 7"H x 5.5"D
MDF, aluminum, electromechanical counter, digital electronics, 110/220 VAC, 50/60 Hz
Primer counts up to the next prime number each time you press the button.
2014, 8"W x 9"H x 6"D
MDF, aluminum, found wood, digital audio electronics, battery operated (3 x AA)
Stanford Totem is a series developed as gifts to encourage/reward giving by certain Stanford University alumni. The wood is found on the Stanford campus, enabling the recipient to keep a piece of Stanford with them wherever they go. Pressing down on the wood activates a digital recording of the Stanford Band playing, "All Right Now."
2015, 6.25"W x 8.25"D x 5.5"H
Commercial receipt printer, embedded microcontroller, 110/220V AC, 50/60 Hz
FizzBuzz embodies a classic interview problem given to programmers: write a program that prints out the integers from 1 to 100, but for every multiple of 3, print the word "Fizz" instead of the number. For every multiple of five, print the word, "Buzz." And, for every multiple of 15, print the word, "FizzBuzz." In this case, the machine keeps printing results until the paper runs out (around x = 16,000) or the power is shut off.
FizzBuzz was the subject of a Kickstarter campaign in September, 2015.
