“I had this old Philips radio laying around that I couldn’t use because it only had an AM receiver. So, I thought it would be cool to make it into an iphone dock =D”

“Mister Gloves is a wireless USB gesture input system that enables a person to use a computer by performing intuitive hand and finger motions in the air. While wearing a glove controller on the right hand, the user can move the cursor by forming a pointing gesture and click by curling the index finger or thumb. Other right hand gestures enable scrolling and provide access to various keyboard shortcuts.”

This week we’re going to have some fun with everything we’ve just learned. We’ll Design an LED Chaser. Here’s a quick intro of what this PyroEDU lesson is all about:

Electronics is not all about theory all the time, some moments do come when you get to have some fun. In this lesson we are going to celebrate our wealth of knowledge and just go design something fun. An LED chaser is loosely defined as a system where LEDs follow one another in a certain pattern, so start go start designing!

“Given that the HP 829292A is one of the hard to find accessories to for the HP Series 80 and it’s a must have if you don’t have some of the original expansion ROMs such as the Assembler ROM, the primary goal of this project is to design and build a functional clone of the HP 829292A module.”

“I needed an idea that I could use to teach myself about using a relay with Microcontrollers and solve that age old problem: Switching between speakers and headphones on my PC without having to actually get up and mess around in the rats nest of wire’s behind it.”

“This amplifier will work great with the crystal radio project. It will enable you to pull in weaker and more distant stations. Local strong stations will have extremely loud volume.”

“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 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?”
