We love a good art-related project here at Hackaday, and [Wolfgang's] vibrating mirror prototype is worth a look: into its distorting, reflective surface, of course.
[Wolfgang] began by laser cutting nine 1″ circles from an 8″ square mirror, then super glued a 1/4″ neoprene sheet to the back of the square, covering the holes. Each circular cutout received some custom acrylic backings, glued in place with a short piece of piano wire sticking out of the center. The resulting assemblage pushes through the neoprene backing like a giant thumbtack, thus holding all nine circular mirrors in place without restricting movement. The back end of the piano wire connects to yet another piece of acrylic, which is glued to a tiny vibrating motor.
He uses some shift registers and an Arduino Uno to control the motors, and although there’s no source code to glance it, we’re guessing [Wolfgang] simply designed the nine mirrors to buzz about in different patterns and create visually interesting compositions. Check out a quick video of the final effect after the break, and if you can help [Wolfgang] out with a name for his device, hit us up with your suggestions in the comments.
