“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.”

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

“This project demonstrates the use of 16×1 line LCD module to interface with Nitron 16-pin MCU, 68HC908QY4. The original idea came from one evening I went out with my son to the park near my home in Korat. The park has a nice walking way for people to exercise. I was wondering how long the distance is?”

“I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor.”

“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.”

“As shown in the schematic, temperature sensor of our electronic thermometer is LM35DZ. There are some kinds of LM35 IC, since it is cheap and easy to find we used LM35DZ in our project. It measures from 0°C to 100°C with a very linear output graph. For one degree change, it increases its output 10mV.”

“This amazing looking device is a quadcopter that was designed by me and my team at the University of Victoria….The purpose of the project was to create a DIY quadcopter for under $200 and push the limits of what the 3D printer in our laboratory can do.”

“Finally I have found some time over the past week-end to enhance my Zumo robot. After I had my line following robot based on the Pololu Zumo chassis and the FRDM-KL25Z, I thought it should be easy and logical to solve a maze. Logical: yes. Easy: not that much. In fact it took me longer than expected. As always, there are a lot of tiny and important problems to solve.”

“RC model helicopter prices have reached a point where all sorts of challenging (i.e. crash-prone) robotics projects become affordable. This document explains how to build a 300 g helicopter with embedded Linux and Bluetooth datalink from off-the shelf components for less than 500 EUR.”
