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 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 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
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 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
Introduction With the Vocal Trainer, expect to resurrect your singing, and ultimately become a vocal expert! The purpose of this Vocal Trainer, designed by Anderson Lin and Jerry Chiang, is to train people in singing accurate pitches, and ultimately become a vocal expert. Also, the vocal trainer has other features such as tuning, in which
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 The project involves an experiment in implementing a human-computer interface by tracking finger and wrist motions. Brief: “Ever wish you could control a computer just by moving your fingers or your hand?” We did. The primary goal is to design and build a functional prototype implementing an intuitive interface for a user to interact
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
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
