MP3 Player From Hard Disk Drive

The project makes use of an IDE hard drive in order to build a standalone MP3 player designed for car, home, or portable use.

A group of MP3 files are played as the MP3 player reads FAT32 file system stored on a standard IDE HDD up to 128GB. A 24-bit DAC provides the high quality audio output wherein both line-level outputs and an amplified headphone output are used. The use of large capacity hard disks reduces the flash based players that contains only a few songs since very high MP3 quality settings are used.

The player is built in a fully assembled and tested circuit board which would only require a power source, hard drive, and memory SIMM ranging from 4 to 32MB. An 8×24 character LCD is used as the display which connects to the 4-port pin of the MP3 player. The functionality of the board’s buttons is duplicated by the 12 pushbuttons which are provided by an adopter board. also provided by the 12 buttons is the on-screen navigation. By sending commands via serial port such as 9-pin D-SUB connector, it is possible to control the operation of the player.
