#About
This is the server side application used to control the 2014 Burning Man project "Segment 16". The server side application is a Rails 4 application that runs on nginx and thin. The application runs on a Raspberry Pi. The Raspberry Pi sends SPI signals to a string of WS2801 addressable multi colored LEDs. CAD Designs will be opensource as well as soon as the become available.

The goal is to build between 10 and 20 of these huge 16 segment displays. When they are hooked together, anyone with a phone or computer can log into the supplied wireless network go to a website and submit phrases to be displayed on the sign. There will also be an iphone app that you can download to control the sign.
