The module consists of a Atmega8 microcontroller. It uses PWM to control 3 different LED’s found in a RGB Led. Because it uses PWM to control the 3 colours we can also control the brightness of the colours. This allows us to create various colours using the three original colors (Red,Green and Blue).[more]

Are you a chess fanatic and you need to play in the dark for some reason? If yes,check out this project.It designed by a member on Instructables, Tetranitrate writes:
had just picked up a cheap-o glass chess set at my local arcade for the low low price of only 15,000 tickets. The novelty of playing with glass pieces quickly wore off, and I wondered how I could make it better. The thought of illuminating the set seemed very appealing, but there were so many different ways that could be done.

Here is the 3×3x3 LED Cube project. It runs using a PIC16F690. Along with the brief explanation of how to make it, It also included the .asm file for the PIC and a piece of software written in VB.NET that you can create your own LED patterns. These can be exported as .asm files and put into the main .asm code.[more]

If you like computer mod this is a cool thing to do.It is a Custom Hard Drive LED & driver or HDD Eyez.The idea is quite simple actually. On/Off blinking Hard-Drive led can get quite annoying sometimes or it doesn’t seem to fit the overall theme of the case or a project.[more]

It uses a matrix of 100 LED’s for a display, and does suffer from being slow and having rather poor resolution. Still we could display a sine wave running at 500Hz without trouble, that that’s not all that dissimilar to commercial solid state osscilloscopes.The circuit displays an understanding of the mechanics of displaying an analogue waveform. The timebase is simply a 555 generating a horizontal sweep, while the vertical amplifier is 3914 with a trimpot on the front. It’s extremely simple, but it works. [more]
