Difference: LyreProject (r90 vs. r89)
Project to design and build a Free/Open hardware audio player (DAP) and recorder, for use with RockBox.
Major companies that build DAPs like Apple or Sandisk, often create new versions of hardware to get lower prices and add new functionality. Since the new versions are usually designed with different chips and are often undocumented, Rockbox developers have to struggle to find information that permits them understand how the devices work, and allow the Rockbox firmware to run on them. Sometimes, before the developers can hack some older target versions, a new version appears and the older version is not available on the market anymore!
Also the same companies make DAPs with lower quality components so they can get lower prices and earn more. Lower quality components usually means an audio signal that is noisy or a DAP with a shorter life span.
Modern micro-controllers and memory have become cheap, and tend to be very fast with a lot of resources inside like DAC and USB peripherals. This means that it is possible to build a reasonably priced and powered DAP with a fewer components. If we manufacture our DAP, we will be able to maintain a much more stable and documented hardware, with a good quality audio and a perfect Rockbox port.

We are actively working got a deal with a commercial partner that will design the board, assembly and sell it online. We can't reveal much more until the hardware is on selling. The hardware will be Open Hardware and is designed with LyreLittlePrototypeKiCAD?and we (Free Software). now have a working Rockbox bootloader. We believe that 90% of the total project is done.
We hope to sell the board on early June 2009 for about $100. Hopefully by July we could have a proper, encased, audio player/recorder.
We are moving to an Phillips LPC ARM9, which is cheaper than the Atmel AT91SAM? ARM9 but also lacks some functionalities. Although this LPC ARM9 should be powerful enough for decoding all audio.
Our actual working prototype is LyreLittlePrototype and we now have a working Rockbox bootloader. We believe that 90% of the total project is done.

On 30 March 2008, Pasen, a company that sells MP3 and MP4 players, contacted us in the forum saying "... we are really interested in producing your players. It's long time we wanted to build an open source player, but being relatively small we can't invest much on it, and thus we are glad to hear of your project", but they changed their ideas.
If needed, contact companies asking for support at assembly and selling the player on theirs online shops - example:
