Introduction PONG, a video game that simulates a game of Ping-Pong between two players, has a long and pervasive history, and is said to be the first video game ever created. For our final project, we decided to pursue PONG with a twist. We designed and constructed a dual player mode, two-dimensional PONG unit. This […]

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

Introduction Perusing through the impressive list of past projects, we decided to make our final project a combination of two technologies—wireless technology and the MP3 player. Specifically, we decided to create an MP3 player that broadcasted the songs to an FM dial. We call this the “MP3 Radio.” To accomplish this, we used an ATMEL

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 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

Introduction: Error correcting codes are used throughout digital communication systems today. Cell-phones, CD players, satellites, digital pagers and many other communication devices all use varying amounts of error control to achieve a certain degree of accuracy in transmitting information. The idea behind error control codes is very simple; one can insert some amount of controlled

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
