Introduction top For our final project, we have designed and built a ‘proof of concept’ prototype for Project Green Stations, an externally funded student group with the following mission statement: Project Green Stations is all about changing the way people see the environment. Imagine the go-green movement as a brand. Solar panels, Toyota Priuses, and […]
Introduction In our final project, we created a smart voice decoder system that is capable of recognizing vowels in human speech. The audio input is sampled through a microphone/amplifier circuit and analyzed in real time using the Mega644 MCU. The user can record and analyze his/her speech using both hardware buttons and custom commands through
Introduction “A composite personal health monitor solution bridges the gaps between patients and doctors.” —Engineering Goodwill This project creates a portable device implementing wireless technology and taking full advantage of the wide-spreading Internet to provide a convenient solution to monitor human health. The health information acquired on the portable side transmits to the server wirelessly

Overview [top] As avid audiophiles, we wanted to apply our newly acquired knowledge of microcontrollers to build a fun consumer electronic device. Our project is a step sequencer drum machine. The user is able to program a 16-step percussion pattern using one of a wide range of percussion instruments on each of six different tracks.
Introduction For our final design project, we designed and built a prototype acoustic modem to serve as a physical transport layer for digital communications. It converts between a digital communications scheme (RS-232) and an acoustically coupled communications scheme of our own design. Our project consists of a pair of such modems to operate as transmit/receive
Introduction This project involves the design and construction of a low-cost portable potentiostat capable of performing cyclic voltammetry on three-electrode electrochemical systems. A potentiostat is an instrument used in chemical and biological tests that controls the voltage between two electrodes, working and reference, at a constant value. Chemical and biological tests are typically run in

Introduction Our final project is a conceptual prototype of a digital receipt system. The basic idea is when making a purchase with a credit or ATM card, the transaction information is automatically packaged and sent to a webserver where it can be logged in a database. A web interface would then allow consumers to log
Introduction Our device is an impedance analyzer that determines the complex impedance of any R-C circuit within an impedance range. Our original plan for creating this device was to develop a body fat measurer, a portable device that could allow users to monitor their health at their convenience. However due to device limitations we were
ECE 476 – Spring 2003Christopher Foster and Jeff Puchalski When Chris and I first started tossing around project ideas, I sputtered out: ‘Hey! Wouldn’t it be cool if we could emulate a Nintendo using some Atmel chips?’ Chris replied ‘Ooh, that’d be awesome, then I could play Ice Hockey and Final Fantasy 1 again!’After looking
INTRODUCTION For our final project, we designed a scanning tunneling microscope (STM) that could be used to gather information about the surface topography of metals and semiconductors at the sub-micron scale. The STM is controlled from a graphical user interface running on a PC. The user is able to set various parameters related to the
