“Take your MSP430 for a spin with Spoke Ink! Spoke Ink is a booster pack that attaches to the spokes of your bicycle wheel. Using an array of 32 RGB LEDs and a magnetic sensor, this booster pack projects a bright, upright image right from the spokes of your wheel. Using our software, you can create this image from any bitmap.”

“The cube described on this page uses a 5 x 5 x 5 matrix of single colour LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn’t take too long to assemble and just fits onto a eurocard sized PCB. The power requirement is under 1 amp and the use of just one colour keeps both the hardware construction and control software fairly simple.”

“The goal of this experiment is to convert the Arduino board into an USB keyboard plus a VGA sniffer to crack the password of a standard BIOS using the brute force attack method. There are no advantages in using this method, in fact this can be very slow and you may never find the password at all, but as always we do it for fun.”

“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.”

“MEng students at Sussex do group projects of their choice. Our group chose to work on a Small-scale Biofuel Production unit, that converts organic household waste to bio-ethanol. The group was formed of four students – two electronic and two mechanical engineers.”

This week, we’re looking at shift registers! Specifically, we’re going to look at how to Design A 4-Bit Shift Register. Here’s a quick intro of what this PyroEDU lesson is all about:

With all the basics covered, we can start to combine digital logic elements together and make useful devices. In this lesson we will take some flip-flops and other logic elements to build a 4-bit shift register. Some LEDs will be used to show you exactly how the shift register works.

“I generally get project ideas before looking for components. For the whistled, things were the other way around.
A few months ago, when finding a new 32pins Cortex M4 , I got plenty of ideas and the whistled was one of them.
As mentioned in the video, this tiny Kinetis K10 can perform around 80 [q15 2048 points] FFTs per second and still give me time to run my own algos.”

“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.”

“This project is my first attempt to make a biped walker — and using only three servos. 3S-1 (for Three-Servo walker One) is modelled loosely after the VStone RB300, as seen in their gallery and discussed in this RoboSavvy thread.”

“Here you will find some info and see some pictures of the second RGB laser projector I built….also see how others have modified their Laser Projectors.”
