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: 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 entire …
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 …
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 project in which a user could control the movement of an Etch A Sketch using a typical serial mouse. The public was introduced to the EAS in 1960 and since then it has stayed virtually the same. This nostalgic toy is recognized by many generations and we decided to put a …
I. Introduction The goal of this project is to build a digital compass that displays both the direction and cardinal points on a television. Other functionalities were added to complement the sensor interface, such as, temperature display, magnetic declination input and disability option. At the highest level, this project involves acquiring two output readings from …
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 The goal of our project was to develop a remote control whose buttons would be readily programmable by recording the signal from another remote control. After revising several standards on infrared signals, we determined that the approach to take was to record the signal by determining the width of the transitions in the waveform, …
I. Introduction Simply write; your computer will undersand! We have designed and implemented a Handwriting Recognition System using a touch screen from a Palm Pilot m125, a black and white TV and a Mega32 microcontroller. Unfortunately, due to the lack of specifications regarding the built-in LCD on the Palm Pilot, we were unable to reverse …
