Buddy: A Breathalyzer For Iphone, Douglas Blaalid, Brandon Bevans

Electrical Engineering

Buddy is a Breathalyzer for the iPhone designed to be more a product than a project. Through proprietary hardware and a custom iOS application, Buddy provides users with a previously untapped link from the alcohol in their body to the display on their phones. Buddy uses an alcohol sensor connected to an Arduino Uno to accurately detect the BAC of the user’s breath. The BAC is then transmitted to an iPhone via the headphone jack where it is displayed and logged in a captivating app. The finished prototype successfully measured the approximate BAC of intoxicated users. The product website has …


The Visual Representation Of Sound For The Hearing Impaired, Jonathan Brophy Jun 2013

The Visual Representation Of Sound For The Hearing Impaired, Jonathan Brophy

Electrical Engineering

There are many difficulties that arise when one is faced with a hearing disability. New applications of advancing technology have the potential to enable designs capable of assisting the hearing impaired with the ability to see sound. This project seeks to provide a user with a visual representation of loud noises detected using small directional microphones. The microphones determine the location of the sound above a set decibel level and a microprocessor determines the approximate location of the sound source and displays a vertical colored bar on a video image in the direction of the noise using virtual reality glasses. …
