Introduction Our project is a UPC-A Barcode Scanner complete with a pricing/description database interface. Our original goal for this project was to build a standard barcode scanner from scratch, but as the project evolved so had to our specification of the project. We initially sought to build a charge-coupled device (CCD) scanner, which scans the […]

Introduction Our project was a real-time weather update system that accepted an airport code from the user via a keyboard, looked up the code on an internet database, and displayed the resulting weather information on a television screen. We used the PS/2 protocol, between a standard keyboard and an Atmel Mega32 chip, to decode the

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

By: Kris Young and Dan Li See the results section for movie clips of the motion capture system in action. Abstract Human-Computer interface may perhaps be both the most limiting and liberating aspect of humans working with computers.It can, for instance, limit the input complexity to the system or may, alternatively, provide a great range

I.Introduction Soundbyte:A Wireless Data Telemetry system that receives acceleration, proximity and external temperature data from a remote vehicle and displays them on an NTSC television screen. The rationale behind this project is to provide the user with information regarding the vehicles acceleration, proximity to other stationary objects, and external temperature. The information gathered would be

INTRODUCTION The DomMeter is a car performance meter that measures acceleration to compute values important to car enthusiasts. Specifically, the DomMeter calculates the 0-60mph time, 0-30mph time, 0-100mph time, quater mile, eighth mile time and braking time, the max acceleration during that interval, distance travelled in feet and max horse power generated (after drag, roll

This is my first AVR-project on this page. The DiSEqC-Tester allows to test DiSEqC-switches that uses 1.0 or 1.1 protocols. (DiSEqC-Switches with 2.0 and 2.1 protocol have backwards compatibility with 1.0 & 1.1 respectively and also may be tested). The device every second sends a DiSEqC-message that makes switch a DiSEqC-switch. Four LEDs are intended

Introduction: My project is a self-powered solar data logger. Put out in the sunlight, it will measure the light level and log this to memory to be later downloaded to a computer. The system is powered by a small solar panel and battery. Summary: The solar logger I built uses a photodiode to measure the

Capturing repetitive waveforms at 1 million samples per second using PWM and a comparator. Download AVR Studio Source wfcao 030326 .asm The impetus for developing this technique came from my own need to capture repetitive waveforms using the least expensive and lowest part-count means possible. I wanted to be able to view the waveforms on

This is a low power signal source I put together one evening to provide 187 KHz RF signals for an anticipated receiver investigation. Under Federal Communications Commission rules inside the United States, one is allowed to operate a transmitter without a license under certain conditions. Here, I have copied the relevant section of the most
