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 Point of Sale systems typically can cost up to thousands of dollars we do it very simply for seventy. For small stores, point of sale systems can be very expensive. One thousand dollars for a piece of machinery whose functionality is quintessentially simple can be exuberant. Our goal was to design a point of

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

Introduction Mister Gloves is a wireless USB gesture input system that enables a person to use a computer by performing intuitive hand and finger motions in the air. While wearing a glove controller on the right hand, the user can move the cursor by forming a pointing gesture and click by curling the index finger

Introduction We created a wearable game controller that uses accelerometers to acquire action of the hand and then maps an action to an arbitrary keystroke. The types of actions we are trying to recognize should be suitable as input control for video games. We placed 3 z-axis accelerometers on tips of the thumb, the index

Introduction In short, our project is just an isolated floating plate. Just as our title explained, it is mainly a floating plate that is segregated from all outside vibration using electromagnetic force. This purpose of the project is to design a system that complements common passive shock absorption mechanics and enhances their performance. The main
Introduction We have endeavored to develop a means by which eye gaze can be detected. This goal was achieved using the same principles learned in Lab4, where we recorded the motor speed of a small hub fan using the combination of IR emitter plus phototransistor, henceforth referred to as an emitter-phototransistor pair. High Level DesignSeveral

Introduction The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by setting breakpoints and accessing registers and memory. We have three main objectives in this report: To enable a user to properly download our code onto

Introduction The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the users head. The idea behind this project was to construct a sixth sensory system that interacts with
