quilted maple, led matrix, wiring board, code, digital image, custom circuit to interface MAX 7219

Every few minutes the led matrix appears through the wood and displays a self portrait, one pixel at a time. In total, approximately 1600 pixels of varying intensity are displayed.

development
The enclosure went through four prototype iterations. The final enclosure was made from two pieces of maple that were hogged out using a milling machine.

The led matrix is driven by a MAX7219 chip using the Wiring microcontroller. The digital image used for the animation was converted to an array of pixel intensities using Processing. The electronics are powered by a 9v battery to eliminate any visible signs of electronics.
