Need Help- I want to build an MP3 Player

[osu1177]

Hello!
I joined this forum because i am interested in making an mp3 player. Ive searched extensively but i was wondering if any of you could help in any of the following ways:
1. Do you know any good sites with step by step instructions? I am pretty much a beginner....but i have a bit of experience from making an amp. (https://tangentsoft.net/audio/cmoy-tutorial/assy.html). I do not want a kit.

2. Id like to make one that sacrifices power output, memory capacity, and, if necessary, sound quality ALL FOR SIZE. This thing must be tiny.

Do you think this is possible? I think it is, but im gonna need alot of help. (also alot of time patience and money, but im willing).


PLEASE PLEASE HELP!

There is a few different designs.

This is reports from a student project. some good info.

Also, look up a MAS3587, it is a MPEG decoder and DAC

I've also been playing with the idea too.

Good luck

go to www.avrfreaks.org and search in the user submitted projects section. You'll find at least 3 MP3 players, at least one of which has schematics, all have source code. It operates off of I believe an AVR microcontroller and reads from a FAT32 hard drive.

PJRC also has a kit, schematics, source, and diagrams for one that is fairly complete. It also reads from a FAT32 drive and uses regular drams for buffer memory. It is based on a C51 of some type.
