Burning Man 2015
I built an approx. 5 ft. tall (6 ft. edge) tetrahedron for the centerpiece of Sexual Babel. This installation was at 7:00 & D as a part of Diva Nation.
This was my first carpentry project, so I learned a bunch of useful things like: use a digital protractor to calibrate your saws. I tried to solve the 70.52º 6ft bevel problem, but ran out of time and used door hinges to join the faces. The sled extension on the table saw was too inaccurate to sustain a 6ft long bevel, so I had to move on for now.
Each face of the tetrahedron contains 220 pixels (4 5050 SMD diodes), which means 660 pixels pulling around 800 watts or so with all pixels white. Each pixel is controlled with 1 WS2801 IC. The brain consists of a BeagleBone Black running inside an antistatic bag, powered by an Anker USB charger, and hooked up to an AllPixel.
