MP3 have become a very common thing in nowadays and almost everyone will have at least one MP3 player. If you have some creative ideas and like to do something with your MP3, then today is your lucky day, as you’ll learn how to modify the MP3 player into a multipurpose MP3stick!
Since this project needs certain of electronics and MP3 related skills, thus it’s not suitable for the amateur. And, if you never have any experiences in the electronics field, then you shouldn’t start this project, but if you still insist to do it, the all consequences are on your own risk!
The MP3stick is a simple and small portable MP3 player and a microcontroller Atmel AVR ATmega128 is the main part of the circuit. A VLSI VS1011b decoder IC does this MP3 decoding, where a MMC/SD card will work as memory medium for all the MP3 files, playlist files and skin files. The player is well designed to draw its power from a Lilo/LiPo battery with 3.6V and a charger circuit, which is based on MAX1811 is included as well!
As a result, all the important information will be shown on a Nokia color LCD with 128×128 pixel and 256 colors. The player works in the text-only mode and if a skin file is available, and with nice graphic skins too!
Lastly, for those of you that are enjoy and able to get this project finished, you’ll definitely love the final outcome.
