Introduction We have designed and built a LED t-shirt capable of displaying the heart rate of the wearer via a pulsing LED heart. Largely, our project consists of two components: the plethysmograph and the LED display. How we came up with the Idea We had thought up the idea of a heart rate display led […]

Introduction The purpose of the project is to present a new approach on the design of security systems by using a touch sensitive device. Security is a permanent concern in a variety of environments ranging from physical access restriction in home and industrial settings to information security in digital systems. Numeric passwords, fingerprint recognition, and

Introduction The purpose of our project is to control a toy helicopter using flex sensors attached to a glove. The flex sensors are intended to replace the remote control that is generally used to fly the helicopter. Additionally we also created another mode which will allow us to use an accelerometer to control the forward

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 We designed a system for wirelessly controlling relays and monitoring current. This is used for a home load simulation. By wirelessly turning relays on and off by sending commands from a PC to a microcontroller we can change the total load (current) to our simulated home. For wireless communication, we used XBee Series 2

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 The goal of our project was to design a low cost and user-friendly FM radio receiver. Our project uses a FM receiver integrated circuit to perform the pre-processing units that are needed before the desired audio signals can be heard. The radio frequency is too fast for processing with our available hardware and the
