We’ve all seen LED fans that you can put in your computer to make it look cool. They usually come in blue, sometimes red or green and consist of a basic PC fan with 4 bright LED’s mounted in the 4 corners. They source their voltage from the fan’s power input, so if you’re using […]

This instructable walks you through programming and using the Boston Android Xmega evaluation board to work as a simple arbitrary waveform generator taking advantage of the integrated 12bit DAC and high speed DMA controller. I have provided precompiled firmware as well as source code which can be loaded onto the device and configured via a

Amazing 3 dimensional LED display. 64 LEDs makes up this 4 by 4 by 4 cube, controlled by an Atmel Atmega16 microcontroller. Each LED can be addressed individually in software, enabling it to display amazing 3d animations! 8x8x8 LED cube now available, by popular demand: http://www.instructables.com/id/Led-Cube-8x8x8/ First of all, you need quite a bit of

This is merely an instructable to explain how this device operates. I hope everything is not too obfuscated. This prototype consists of three 8×8” modules. Each module operates independently of each other. Each module consists of 4 “pixels”. Each pixel is 4 inches square and consists of 21 LEDs, two IR emitting diodes, and two
In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex. I have added another part to

You can’t calculate binary values “as is” on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo. So join me as we are going to enter the world of ones and zeros

I recently started programming AVR chips, namely the ATTiny85. They can be programmed using C, compilers are readily available in Ubuntu, and you can do a LOT with them – just search for avr on this site! Anyway, I was having some trouble with my project today – the LED wouldn’t flash! I couldn’t figure

If you’ve ever wanted to power your Arduino or AVR from a battery for development testing (batteries have different power delivery qualities than, say, transformed AC or even a regulated wall wart in DC) testing but were tired of going through batteries (Hey, I admit I’ve sucked batteries dry in hours because of a slipped-up

Hack a wireless home automation system to be USB controlled using two AVR microcontrollers! Check out the video! The system is really more responsive, but the browser on my phone is slow. Skills ans tools There are two ways of hacking an RF remote to be controlled by a computer or a microcontroller. The lame

These Android figures are cute, but they don’t actually do anything. Let’s change that. Have a look at the video: These are the steps to make an Android that reacts to sound, moves it’s head, sends out Morse Code messages and displays some cool light patterns. In the video the LEDs in the body are
