Hello! I'm looking for a way to build small mp3 network player. It should be something like http://mp3elf.net/ but cheaper. Could you suggest me some embedded system that has: - low price - stereo output - ethernet with tcp/ip - rs232 (not necessarily) - lpt (for LCD) Of course, it should be fast enough to decode 320 kb/s mp3 files. System could be stored locally on flash or booted over network. -- Nastyd

Hi, Easy with the VLSI chip (VS1001). Have a look at my page (in french, but for the photos) : www.le68hc908.fr.st => "Lecteur MP3" Regards, -- Yvan http://www.ybdesign.fr "Nastyd" <nastyd@fuckspam.o2.pl> a �crit dans le message de news: c8o1ac$q9r$1@news.onet.pl...> Hello! > > I'm looking for a way to build small mp3 network player.

I would like to know what are you starting with ? Do you have any microcontrollers available to you ? Are you going to have to buy everything needed to build this project ? Do you have the experience to build and code something like this ? How much is your time worth ?? Nastyd wrote:> Hello! > > I'm looking for a way to build small mp3 network player.

Ideally I would like to use PC/104 board, but it's too expensive.> Do you have the experience to build and code something like this ?Very little experience in electronics, but I have some in coding in asm and C/C++ on x86 and 8051.> How much is your time worth ??I have plenty of time!

I would just setup a playlist > from a network server.It should display what is currently playing and volume, but it isn't necessary. In future, I would like to control it with PDA connected to the network with 802.11b.> If you must have a screen, the compaq internet appliance (IA1 or IA2) > would be a good cheap box (<$100 on ebay) for this.No, I don't want a screen. It should be as small and cheap as possible. I want to place it in the kitchen and the bathroom.

But, jest aside. Yes, there is dedicated hardware that is a good deal more energy-efficient than a general-purpose microprocessor at decoding MP3s. The German computer magazine c't was just recently running a project called BlueMP3. Sounds quite like what you're trying to do. They use a dedicated MP3 decoder chip called VLSI VS1001k. A pre-assembled board is still in the 90 EUR price range, though. -- Hans-Bernhard Broeker (broeker@physik.rwth-aachen.de) Even if all the snow were burnt, ashes would remain.
