Easy Input is a head-controlled keyboard and mouse input device for disabled users. The system uses accelerometers to detect the user’s head tilt in order to direct mouse movement on the monitor. The clicking of the mouse is activated by the user’s eye blinking through a reflective sensor. The keyboard function is implemented by allowing …

Introduction Single sentence summary A programmable laser light show that allows the user to specify the pattern displayed via three motor speeds and the length of time that this pattern is held. Project Summary For this project, we designed a system to guide a laser beam through an array of three rotating mirrors and then …
Introduction Infrared (IR) Our project is an infrared (IR) tracking system. A beacon, placed on the object to be tracked, continuously emits infrared signals in all directions. The signals coming from the beacon are detected by 2 IR receivers mounted on 2 stepper motors, which rotate independently and are in separate locations. The direction each receiver …
Intro Summary Thinking about what a CDE (culminating design experience) should be, we devised a project that combines the microcontroller programming principles learned in ECE 476: Microcontroller Design with the control theory concepts learned in ECE 472: Feedback Control Systems to create an academically viable stationary helicopter. The device consists of a lever with a …
Introduction “Our 3D gForce Mouse will enable use to move the curser in the air freely with the capacity of scrolling” The rationale for this design is two fold. We wanted to do this design because we wanted to make a zero-impact pointing device for those with injury. We also wanted to implement this injury …
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 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 …
