“The main reason that I wanted to build a DIY Segway was simply because I wanted to see if it was possible. I also liked the idea of building something that strongly interacts with humans. I will now describe how I built it.”

“Our final product – again non-commercial – is a pair of shoes attached with ultrasonic sensors on the sensing side. The information, obtained from these sensors, is used to form a virtual map of the surroundings.”

“The idea of building my own I2C smart DC motor controller is came to me when I was learning and playing together with my son on his LEGO MINDSTORM NXT 2.0 about a year ago. The NXT sophisticated controller also called NXT Intelligent Brick is powered by Atmel 32-bit ARM7 AT91SAM7S256 microcontroller and communicating with Atmel 8-bit AVR ATmega48 acting as a co-microcontroller using I2C protocol.”

“We chose this project because of a combined interest in brain-computer interfaces. In an attempt to balance cost, complexity, and sensor density, we decided to implement a NIRS-inspired system. After collecting data from the array, the results were sent to a computer and displayed in a Java GUI.”

“Our ECE 4760 design project integrates three different kinds of sensor measurements to track a user’s movement speed, regularity of gait, force on impact, pronation of foot, as well as other information that may be useful to a podiatrist.”

“The story behind this experiment was to investigate the average wind speed to motivate a future wind turbine project. A commercial logging weathers station cost much. So this is an attempt to build a good alternative cheap solution.”

“Working with embedded electronics, you will eventually end up with some sensor between your hands and here I’ll show you how to make a graph out of the data! This project involves a light sensor, a tiny 8-pin AVR USB key with the V-USB stack, a GNU/Linux system and rrdtool.”

“The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion equation will be derived and implemented in the firmware of the PIC microcontroller and the actual load current will be displayed on a character LCD.”

“This was the second robot I made for collective motion research purposes. As you can see, it is vastly simpler, cheaper and easier to build. Of course it doesn’t have nearly as many features or as much potential as robot 1, but I think it is much better for what I’m trying to do.
Here’s a picture of the prototype without the battery.”

“My main objective in this project is to work on core computer vision algorithms which enable the blimp to navigate through its envirnment autonomously. The camera is the most important sensor – it provides continuous live image capture for onboard ‘optical flow’ calculations, a very effective technique for obstacle detection and velocity measurement.”
