This stand-alone internet wireless music player, named as Wireless MP3 (WMP3), uses Atmel AVR AT90CAN128 microcontroller as main ‘brain’. The device can play music from internet radio stations like Shoutcast (, connect to shared network drives and play mp3 files. Ubiquitous 802.11b wireless link is used to connect to the internet.

“WMP3 uses HTTP protocol to search online servers. Once the location of the radio station is identified, WMP3 directly connects to the server and start playing the streamed data. Another important feature in WMP3 is its ability to list networked computed and then play music files shared in their directories. This is very useful if you have an extensive collection of music stored in your computer. The most important part is that WMP3 does all these without installing any utility in your computer”, said Mohammed Rana Basheer, the project designer.

The main components in WMP3 are AT90CAN128 Microcontroller, STA013 MP3 decoder, 802.11b PCMCIA card, Power Supply, and 128 x 64 monochrome display
