Introduction Our project is a digital stethoscope that displays your heartbeat on any television. It also calculates beats per minute and alerts you if your rate falls out of a specified range. At the highest level, the design of our project centers around an acquisition circuit, data processing in two MCUs, and the output on […]
Introduction Our ultrasonic rangefinder is capable of allowing the user to determine his or her distance from an object or wall. When deciding on what type of project to design and construct, we decided that we wanted to create something that would have some practical use in life. Many groups in the past created video

Introduction We created a wireless device to affix to the bottom of a pitcher that alerts the wait staff when the pitcher is empty. We used the a priori knowledge that when a pitcher is empty the pitchers bottom is perpendicular to the ground. By affixing an accelerometer to the bottom of a pitcher we
Overview The SmartBlinds system uses a microcontroller to control the angle of a set of miniblinds used at home, in the classroom, or on the job. Using SmartBlinds, a user can more effectively control the light coming into the room, or have an alarm that opens at a specified time. We’ve noticed that despite the
Introduction Let us introduce the Breath-o-Matic alcohol sensor. The Breath-o-Matic is an electronic, non-invasive method of measuring a human’s blood alcohol content (BAC). Its elegant, yet discombobulated design embodies a cheerful mix of mechanical and semiconductural components. Simply blowing into the mouthpiece causes the Breath-o-Matic to automatically begin taking a sample of your own foul
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

Introduction Our project is an autonomous toy car that tracks a high pitched audio signal. Using two microphones, a microcontroller, and two DC motors on an existing remote controlled car and, we implemented our own control logic to detect high pitched 3.5kHz audio signals and drive the car. This project consists of both software
Introduction Sound Bite We implemented a black-and-white video (TV) game adaptation of the old DOS classic known as Digger, by Windmill Software. Summary On the Game Start screen, a choice between a multiplayer mode and an AI mode is offered. The multiplayer mode supports three players simultaneously for the Digger and both Nobbins. In the
Our System acquires several different sensor inputs, FM modulates each level by manipulating Direct Digital Synthesis increment values, transmits the resulting signal on a commercial FM radio band, and receives and decodes the original sensor levels. Introduction The problem of encoding multiple input signals into a finite bandwidth space is one that is common in
Introduction Sound Byte This project is a proof of concept diagnostic & testing board for use with the power board in the Cubesat Satellite and will be developed further to become a component of the CUSat Satellite. Summary of What We Did and Why This projects goal is to create diagnostics and testing hardware for
