"For our design project we constructed a polygraph which measured pulse rate, GSR, and breathing rate, and performed a discrete cosine transform on the subject’s voice in the hope of measuring a deviation in the fundamental frequency. The measurements were sampled, analyzed, and transmitted to a computer for further analysis using an ATMEL AVR Mega32 microcontroller."

"We have been working on a system to count the number of cups of tea and coffee made on each floor of Imagination’s offices. The #activitea project was started to better understand and illustrate hot beverage consumption at Imagination’s London offices; and to test a process that could serve many other data capture uses."

"The project consists of both a custom hardware front-end for data acquisition and an Android application for visualizing the collected data samples to the user. Data is transferred over USB to the Beagleboard running Android, and then plotted on an external screen."

"The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the user’s head."

"The 2009 Robot Rally spotlighted all the flaws that result from a quick 3 week engineering and building project. Time saving shortcuts in code and hardware bit my butt several times. Failed edge detectors – Ouch! Failed beacon tracker … chomp! Ow! Line follower reversal – Arrrg! I’m happy to report I’ve investigated all the issues that cropped up and fixed them all."

"The Haptic Creature has three degrees of freedom through which it communicates its emotional state: a pair of ears, which vary in stiffness; lungs, which simulate breathing; and a purr box, which renders a vibrotactile “purr”. The robot has an array of force sensors across its body to sense touch and an accelerometer to sense movement."

“Using an add-on card to the already existing avr ethernet board we build a weather station. That is: A weather station with a build-in webserver…The system is modular. You can either build a pure Ethenet weather station or an Ethenet weather station with an additional local LCD display.”

“Goals: [1] Create a wireless device that sends data from a simple tilt switch. [2] Use a PC to capture, analyze, and detect shaking mosion…..Method: Place a simple tilt switch on a wireless RF board (PIC12F675). Receive the RF data onto a USB PIC (PIC18F2550). Transmit the data to a laptop using USB serial port emulation (PBP code). Analyze the data using Processing, identify and visualize shake-motion.”
