Since the last update the radio has gone through some drastic hardware changes. There is still an Arduino driving the LCD and user interface but the backend has been replaced by a Beagleboard running Angstrom Linux. This has enabled the radio to stream and play MP3 files and also allows the use of Wifi or 3G data dongle.
BBC R&D North visited Maker Faire in Newcastle on the 12th and 13th of March 2011.
