1. Dino Light Spencer Dennis, William Gowell, Zack Teasdale
RIT Computer Engineering Senior Design Project—Spring 2017
Complete Setup
Our project uses a Raspberry Pi and an FPGA to achieve dynamic backlighting. The Raspberry Pi hosts a static web app and a web server. The app talks to the webserver using HTTP requests to configure the system. The web server talks to the FPGA over the Pi’s UART connection. The webserver can also generate patterns to be displayed on the LEDs. The FPGA handles the actual image processing for the system, calculating each of the individual backlight colors, and communicating with the LEDS on the back of the TV.
The goal of Dino Light dynamic TV backlighting system is to bring an immersive experience to todays TV watching and game playing experience.

Simple user interface
The Dino Light HDMI averager is configured and controlled through a simple web interface hosted on a RaspberryPi. This interface sis used to configure the device as well as control its operation. Strips of NeoPixels are mounted around the border of a TV or projector and are used to display the border average on the wall. We also have the ability to interface with an existing Philips HUE lightbulb setup, and send the screens average color back to the HUE bulbs lighting up a whole room.
