Small & Open Source

The article ‘Femto OS’ in last month’s Elektor provided a practical entry point into the world of AVR multitasking operating systems. If it inspired you to investigate further and take a look on the Internet, you doubtless discovered plenty of other Open Source projects of this kind.

This article explains how to use the Elektor Internet Radio board for developing your own extensions and realizing your own projects around this amazing piece of condensed technology.In the first part, we’re going to describe the tools needed and how to use them; in the second, we’ll be developing a concrete example around an LED.

Nowadays audio broadcast signals are compressed and put into IP packets that are ‘streamed’, and you can access every Internet radio programme in the world by receiving, buffering and decompressing these packages. This is all very easy with the state-of-the-art hardware described in this article.
