"At the highest level, the design of our project centers around an acquisition circuit, data processing in two MCUs, and the output on a TV screen. The first part of the stethoscope is the acquisition unit, which consists of an actual stethoscope mated with a microphone, and an amplifier circuit. The microphone captures the audible signal from the body that is acoustically amplified by the stethoscope."

"Over a year ago I started to work on a small balancing robot. Between learning more about communication protocols and feedback loops I also had periods of schoolwork that kept me from this hobby. In the end my little robot was balancing on his own and I could send steering and throttle commands wirelessly."

"On this site we have published complete directions on how to make your own sentry gun, which autonomously tracks, aims, and shoots at targets…We are a unique project in that everything we do is completely open-source. This includes 100% of our code, as well as our electrical schematics, and even the CAD design files for our Standalone Controller. Our system has been used on six continents and in more than 20 countries (so far), and is even used by the Australian Navy in their training program."

"Wearable health monitoring systems integrated into a telemedicine system are novel information technology that will be able to support early detection of abnormal conditions and prevention of its serious consequences. Many patients can benefit from continuous ambulatory monitoring as a part of a diagnostic procedure, optimal maintenance of a chronic condition or during supervised recovery from an acute event or surgical procedure."

"The Haptic Appointment Manager manages all of an individual’s appointments, ensuring they arrive on time and in the right location by subtly guiding them throughout the day.
This system uses a GPS receiver and a compass to maintain awareness of its absolute and rotational position. By interfacing with a calendar of time stamped waypoints, this system effectively guides the user to his appointments by vibrating in the direction of the next waypoint."

"The main idea behind this project was to construct a system on the Altera DE2 board that is capable of detecting the location of a sound source. We envisioned many purposes for such an instrument in gaming and other types of systems; however, to demonstrate our sound localizing capability in this project, we decided to use it for robot control."

" The last thing you want to do is clear up your Monday schedule to go kitesurfing and find yourself cursing the gods on a windless lake after two hours of driving. I needed to know the wind conditions of my favorite kitesurfing spot—in real time. So I decided to build my own weather station."
