Introduction: Our ECE 476 Spring 2002 final project is a musical synthesizer that mimics the sounds produced by a piano and a clarinet. We wanted to create a device that could produce different musical signals by direct digital synthesis. Using Fourier analysis of the signals, we were able to imitate the sounds from different musical […]

Introduction For years scientists and scholars alike have been plagued by one common obstacle which, until now, has proven to be impossible to overcome. How do you find the country you want on a globe? Sure, the easy answer is to just use the longitude and latitude coordinates, but really, that’s quite confusing. Some may

Introduction With all focus of computer technology advancement placed on processors and memory, sometimes the most simple of components are overlooked. This is especially the case with the mouse, a device that has changed very little since its conception by Xerox. It still retains its basic shape and function in moving a cursor within a

Introduction What is Snipertag? Snipertag is a variation upon the very popular ‘Lasertag’ game. In 1986, a company called Worlds of Wonder came up with the idea for a combat game that worked around a set of commercially produced toy laser guns and sensors. As of recently, many companies have picked up were Worlds of
Introduction: The basis of this project is to create the game fish on the Atmel board. In the game fish, the big fish eat the small fish, so your job is to eat the fish smaller than you while not getting eaten by those bigger than you. You �eat� a fish by moving close enough

Abstract For a final project for EE 476 at Cornell University under the instruction of Bruce Land I designed and built a fertilizer flow rate control unit tailored to the needs of Lin Davidson. Instead of conventional mechanical drive methods, the delivery rate was controlled through the use of an Atmel AT90S8515 microcontroller. Ground speed

Introduction Sound byte For our final project, we are redesigning the classic battleship game to suit the needs of engineers. We are removing the need for communication, but keeping the feel of battleship. So what are we really doing? Instead of having engineers mumble battleship attacks, all communication is handled by two micro controllers, one
Introduction Unexpected cardiac death, also known as sudden death is a frequently fatal form of arrhythmia which kills more than a quarter of a million people each year in the United States. Confronted with the devastating effects of unexpected cardiac death and with the pursuit of advance understanding of cardiac diseases, my partner and I

Introduction Imagine being able to monitor the status of a given room or area from anywhere in the world, at anytime. In today�s booming technological atmosphere, this dream doesn�t sound so far off. However, imagine being able to do this cheaply, while not sacrificing efficiency and functionality. Our microcontroller web-monitored thermostat does exactly this. It

Introduction: We thought it would be interesting to try and construct a simple modem out of the ATMEL 8535. The main motivation for doing this was to test some DSP theories about the effects of transmission power, noise, and modulation technique on the bit error rate. Initially, we wanted to connect our modem to the
