After reading the [CT article](http://www.heise.de/ct/ftp/projekte/bluemp3/) about the [BlueMp3](http://www.bluemp3.de/) player, i knew i need this piece of hardware. It’s an bluetooth mp3 player based on the Atmel [Mega128](http://www.atmel.com/dyn/products/product_card.asp?part_id=2018) cpu. The firmware [source](http://www.beecon.de/projekte/BlueMP3-ct/BlueMP3-Firmware-ct_1.5.zip) is available and the [client](http://www.beecon.de/projekte/BlueMP3-ct/l2send-1.8.zip) is linux based. So what do i need more to play around? I ordered the pcb and parts at [Segor](http://www.segor.de/). The Bluetooth module and the Atmega was pre-solderd, because it’s not easy to solder [TQFP’s](http://en.wikipedia.org/wiki/TQFP) at home. The thing was build after a hour of soldering and worked perfect. But the bluetooth signal just worked over 5 meters. So i added an Lambda/4 antenna (thanks tobi) to the bluetooth module, which extented the coverage up to 20 meters. But what i really needed was a GUI to play my mp3s. Since iam [KDE](http://www.kde.org) user i deciced to programm my own Gui called **k2send**. I setup a [project page](https://developer.berlios.de/projects/k2send/) a [berlios](http://www.berlios.de) for it.
