The internet hosts lots and lots of online radiostreams, most of them with a certain theme, ranging from old time classics to Tibetian riverdancing. I must admit that I love to listen to them while I’m building stuff, as I can choose the music I like without listening to the same cd’s over and over […]

Programming AVRs is fun, but sometimes the manufacturers development environments make code maintenance a chore. If your looking for a free, cross platform, high quality piece of software for programming AVRs Eclipseis a good choice.Moving to an Integrated Development Environment (IDE), such as Eclipse is a logical step up from learning to program basic functions.

Lampduino is a computer-controlled free-standing floor lamp, comprised of an 8×8 RGB LED matrix. The lamp stands 45″ high and 18″ wide. Light emanates from both sides. It has various display modes, as well as an included editor for creating animations. The lamp is controlled via an application running on a PC host. The display

While I was finalizing e-snowflake project, I imagined that single RGB 5050 LED would create nice rainbow effect if placed inside a ball like ping-pong. You can find plenty of such projects on the net, this one was heading to embed everything within ping-pong, battery included. The design challenge was to create PCB small enough

This instructable describes how to charlieplex a bunch of 7-segment led displays. Charlieplexing of discrete leds has been the topic of a few other instructables. The Charlieplexing LEDs- The theory and the How to drive a lot of LEDs from a few microcontroller pins comes to mind. They are both excellent and should be read

Nokia manufactures a wide variety of cell phones and many of their cheaper phones contain simple LCD’s which may be used in microcontroller projects. There is one particular LCD model that is used in a wide variety of their phones and is often referred to as simply a “Nokia LCD“, or “Nokia 6100 LCD”. I

Have you ever been chugging away at a project(s) and the project keeps growing and growing, while you add more things to it (we call that a Feaping Creaturism)? On a recent project, I was building a frequency meter and added a five function signal generator/frequency synthesizer. I soon wound up with more switches than

If you’d like to test the waters of microcontroller programming, the new AVR Dragon by Atmel Corporation is a nifty, low-cost entry-level development tool. Unfortunately, right out of the box, the AVR Dragon is not the definitive answer for the beginner looking for an all-in-one solution. Rather, the AVR Dragon is a great microcontroller programmer

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when “sets”
