A Low Power Touch Screen Document Viewer, Chris Perfetto Jun 2010

A Low Power Touch Screen Document Viewer, Chris Perfetto

Computer Engineering

This document will cover the requirements, design, implementation and testing of a low power touch screen document viewer to serve as a replacement bulletin board. It was Implemented using a BeagleBoard development board, a 4.3” touchscreen LCD and a SD card with a Ubuntu Linux OS installed. The testing of this device is primarily testing the power consumption. The device is not yet complete and will require further development for it to completely satisfy the requirements.

Pretty Lights, Nicholas (Nick) Delmas, Matthew (Matt) Maniaci

Computer Engineering

Digital media players often include a visualization component that allows a user to watch a visualization synchronized to their music or videos. This project uses the visualization plugin API of an existing media playback program (WinAmp) but it displays its visuals using physical LED lights. Instead of outputting visuals to the computer screen, data is sent over USB to a micro controller that runs the LED lights. This project aims to give users a more visceral visual experience than traditional visualizations on the computer screen.

Utopia 3.0: Power Cycling Controller Board, Allan Chan Mar 2010

Utopia 3.0: Power Cycling Controller Board, Allan Chan

Computer Engineering

The Universal Test & Observation Power Interface Adapter (UTOPIA) is a device used for hard drive testing by Western Digital. Utopia is designed to provide an interface to communicate with a hard drive and perform power cycling functions on a hard drive.

The purpose of this project is to develop a prototype that retains the features of the previous Utopia boards while including two new features to be used in the next design: voltage margining and improved Serial Input/Output (SIO) drive control.

This document describes the design of version 3.0 of UTOPIA starting with component selection, schematic design and, PCB …
