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 […]

This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using

I really like nixie and numitron clocks, but I never worked with them before. So I decided to give it a go. I choose numitrons because of 2 reasons: first of all nixies need a higher voltage than numitrons to work. Nixies need around 170V DC and numitrons only 4,5V so they are safer to

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
