That's why open source HW is much harder. You need real money to pay for all the physical stuff that need to be put together and shipped. Spare time and skills are not enough.

I understand but at the same time we have examples of Daisy MP3 selling at Makezine - http://store.makezine.com/ProductDetails.asp?ProductCode=MKMP3KIT
Maybe we can find someone interested in assembling and selling the player.

After you said Atmel ARM, I saw that a AT91SAM7S32 cost £3.91 in Farnell :-)
Is that possible to have one page in twiki for resuming ideas for this project?

I too had the idea of an open hardware player, and I looked at the AVR32 as well
(BTW there is a very nice development platform for this that sells for $69-$100).
The avr32 is simply an all in one chip, but there are arm chips like this too
(Philips makes one that is very similar and made for media players).
The real advantages of an open hardware player vs porting to an off the shelf player is that it won't get discontinued once Rockbox is ported to it, and ALL the documentation would be available so the port would be as good as it could be. The major disadvantage would be cost, since you'd NEVER be able to make enough of them to lower the price to match what Sandisk, Toshiba, etc can do. Also there are more open software developer types out there then hardware.
Still, wouldn't it be nice to have a Rockbox platform that would be as long lived as PC's have been (and as well documented!).

scharkalvin, do you want to join forces and start studying the idea? - for me this would be a great investment for my technical formation.
scharkalvin:
At this point I'm not good for much more than ideas.
I wish I was good at cad software for schematic capture and pc layout.
THAT is CRITICAL to getting a design going. If someone gets a wiki page
going, I'd be happy to post some hardware ideas, links to documentation
I've found, etc. You'd need someone with the CAD skills to actually get the
design to the point where you could start ordering PC boards and stuffing them.
(not to mention surface mount soldering skills ....)

Well, I can get one wiki for this project, however, I think that It should happen here at RB! - It would be good for both projects, both can win. To who should I ask for use RB Twiki?
I work in a company that makes lights for automobiles with LEDs - http://www.plurirede.pt/ - we make PCB drawings, I can get some ideas with my friend at work. We normally buy 4 or 8 units PCBs for prototypes from FAST PCB PROTOTYPES companies.
We also have a machine for drill PCBs... I will be able to take some ideas for project.
But I am sure that we will find someone that does that job as profession and that will do that part of project.
I already made some simple electronics projects in group, wich I just did programing and not PCB drawing. You can see more here at my homepage:
