Welcome to the Rockbox Technical Forums!
Once the schematics is finalized we can hunt for vendors to make the PCB.
FYI: to use HDD in portable player you need to use the slim style (1.8") drives that are used in UMPCs. These are even smaller than laptop drives. I guess these don't come greater than 80GB to date.http://www.hitachigst.com/portal/site/en/menuitem.791419b49758db5deb4703e3aac4f0a0/They are relatively expensive that 2.5" drives but still they are cheaper than flash. you could buy a 20GB slim drive for under $80if we can support IDE interface then we can support both CF cards and HD Drive on the same electrical interface.

Also note that laptop drives are now going to SATA and this trend will spill over to the 1.8" size soon.

Spark, can you please answer to my question "As you suggest, after finding a vendor for PCBs, who will buy components, assembly it in quantities and sell it online?" - Do you have a better option?
sorry casainho, i missed to reply to your question. i don't have any option yet, but definately there will be many guys interested once we have Rockbox runnin on RockboxPlayerProto. And there is quite some time for that.
If we have the schematics done for V1, don't you think vendor's like olimex will be interested?
more than the PCB and assembly i'm worried about the enclosure. u know anyone who can make and sell an enclosure at a cheap rate?
However, I changed a bit my ideas now :-) - we don't loose nothing in have it designed by ourselfs, specially If we have resources to do that, If you like and want to do that, go ahead :-)

I'm new to KiCad, so i will have to do some learning on that first. We also have Matt now with us.
About Matt, I had chat with him yesterday. Matt told me that he must have the board designed and produced in 1.5 months!! He will be able to assembly a few for developers, we need to send him money for the components and board. He estimates a price of no more than 100 €.So he will just make the board for his project in school and after we can continue with the software porting.
Spark, I apologize for changed my ideas, since you suggested the same as Matt! I think it shows my inexperience :-)
Rockbox will be stored in spi flash and be copied to ram upon bootup. This means that it will be necessary a larger SDRAM value?
oled displaycan we have datasheets of the oled display? how many colours does it support?
spi flash or NAND flashQuote from: casainhoRockbox will be stored in spi flash and be copied to ram upon bootup. This means that it will be necessary a larger SDRAM value?Why not NAND flash? We can have a 8Gbit (1GByte) NAND flash for $16. This can serve as firmware space as well as media storage. http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=557-1373-1-NDLinux can also be used. you can literally swim inside here. It can also save you from buying an SD card.
