Introduction This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller. The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely in C. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal. …
Introduction Low-Cost Turbidity Meter for Underdeveloped Countries Our project is a collaboration with an independent research project being conducted by senior civil and environmental engineering student James Berg. The goal of this project is to create a low cost turbidity meter for use in under developed countries. Real laboratory turbidity meters can cost over $1000.Our …

his project shows the temperature on a three digit 7-segment display, it measures the temperature from -9.5 to 99 degrees Celcius in 0.5 C steps, or from 0 to 210 degrees Fahrenheit in 1.0 degrees steps. Because of the LED display the temperature is also readable in the dark. This project is available pre-assembled and …

Introduction Let us begin with one key observation: cars are cool. From consumer transportation to manufacturing to childrens’ toys, vehicles in their many forms are some of today’s most influential machines. Autonomous vehicles are already in use in many manufacturing facilities, and they are also sold as toys. Perhaps one day, the world’s highways will …
Introduction The SearchBot is a fully functional model car that can be controlled wirelessly through the PC or autonomously search for red balls scattered on a flat surface. Autonomous vehicles are just now being realized in labs around the world and will soon have major military and commercial potential. The Adaptive Communications and Signals Processing (ACSP) Group …
Introduction Our project is a battery-powered toy car that is able to follow a path against a background of contrasting color. <> The front of the car is fitted with an array of three photosensors, which allows the car to detect the path as well as any turns in the path. Colors that …
1. Introduction The game consists of two levels. In each level, a LCD TV screen displays the 2-D top view of the a parking lot, and the player needs to park the car into the proper parking spot by operating on a fake steering wheel, gas/brake pedals and gear stick. On the hardware side, for …

Our ECE 4760 final project was to create a virtual saxophone that uses Direct Digitial Synthesis (DDS) to synthesize the output notes. Pushbuttons are connected to a PVC pipe to mimic the saxophone’s mechanical structure, and a microphone that detects noise is used to determine whether or not the user is blowing into the device. …
