“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.”

“This is the dedicated page about our first kit project – Eternal Free-swinging Pendulum, also known as Omni Pendulum. It’s a long and detailed story…”

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

A great strength of digital circuitry is that the clock can act as a timer or counter with appropriate flip-flop circuitry in place. In this lesson, using some LEDs, we will learn how to build a 4-bit binary counter that uses the clock input to tell our circuit to increment a counter with every clock period.

“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?”

“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.
