This Spatial Media I project reveals the inner workings of previous designs and was inspired by Damián Ortega‘s disassembled 35mm Olympus camera. Olympus, 2009‘s twenty-six plastic sheets display camera parts in a horizontal line. For my project, a half-inch acrylic plate supports the layers: thermo-formed acrylic face, two-way acrylic mirror, vinyl mask that allows limited LED light to pass, laser-cut acrylic grid (in the shape of a brain) that traps light, and an electronics panel. The micro-controller, breadboard, neopixel LEDs, Ping))) connections, and power adapter fit on a clear acrylic sheet. Laser-cut holes provide a place to mount the Arduino and pass a barrel plug.
Individually addressable LEDS are controlled by an Arduino Uno micro-controller. Twenty-eight LEDs flash brighter and faster as viewers approach Ping))), a sonar proximity detector. The red, green, and blue color channels are programmed to fire randomly (0–254) and simulate brain neurons. Full-power flashes that are five milliseconds apart indicate agitation if the frame’s “personal space” is violated.
