Rockbox Player - Project to design and build a Free/Open hardware audio player
fatfishy:
I don't know what kind of screen you would need, parallel or otherwise, but these seem nice
http://www.matrixorbital.com/index.php?sort=3a&page=1&cName=lcd-mop-graphic-lcds
~$23
and psp replacement screens (Sharp LQ043 K3146) are $30

fatfishy, thank you :-)
I would go for the, http://www.matrixorbital.com/product_info.php?pName=mopgl16064abyfy&cName=lcd-mop-graphic-lcds , because is cheap ~$24, simple to make software drivers for sure and looks like to have large pads for wiring.
I could not find datasheet, I would like to know If I can buy It on Farnell or Digikey and If it have backlight.

Hello people,
i have some design experience with DSPdap http://dspdap.sourceforge.net
i could contribute something to the open hardware player.
let me first tell you guys what i think.
* Building a dedicated rockbox player is not gonna save the work of rockbox porting guys. there is always gonna be a demand for rockbox on commercial players
* building a player is gonna be more expensive than buying one off the shelf
* the player must have an attractive and robust casing. holding the electronics, LCD, disk and batteries together is not that easy. getting a look anywhere close to the commercial players is impossible.
* once the h/w development is done, someone needs to provide DIY kits and also fully assembled players, else the only guys using this player will be the developers themselves. :-\ we don't want the design to rot in our shelves after it's done right?
* The only case i see a potential for the open player is that if rockbox cannot be ported on commercial players. is such a thing possible and when? this question goes out to the rockbox porting guys.
This is not to discourage us, but to make sure that our efforts won't go in vain.
-spark.

There's still lots of Rockbox potential on a wide range of current targets. IMHO.

Welcome Spark and thanks for being here. Since you already made a dap, like the one that is pretended(except with the LCD), what things you could not implemented? what would you do in a better way? I would like to ear you about your experience.

I believe that full assembled players can sell by some companies, I can give 3 examples:
* http://store.makezine.com/ProductDetails.asp?ProductCode=MKMP3KIT -> a DIY MP3 player but with MP3 IC decoder - why not upgrade for a better player version?;
* http://www.olimex.com/dev/mod-mp3.html -> Olimex MP3 player module;
* http://www.embedded-projects.net/index.php?page_id=165 -> USBprog - An open source all purpose tool (AVR ISP, ARM7/ARM9, AT89,JTAG, RS232, IO).
All this companies could be interested in sell assembled DAP, I believe. After we can try to find some others that make plastic cases, maybe that others companies can help on that, they should have contacts, experiences. I am also counting on someone in the community that have experience on this and can guide that part of the project.
Today, a guy send this message to mailing list: "Hello all! I will probably buy a new iPod Nano tomorrow. Now, here's my question: are all iPod Nano generations compatible with Rockbox or is there a generation (like the newest generation) that isn't compatible? Of course I don't wanna get an iPod I can't use of course! :-) Thanks! Robin"
And one answer: "Hi: The latest iPod nanos are not compatible with rockbox at this time. I would look on ebay for older iPods that are. I my self was lucky and bought an Ipod 5.5 gen back in June when they were still being sold."
I don't think that is good for people have to buy used, old players. Will that guy do that? - In future we could also advice a not so looking nice and cheap player as Ipod but a perfect supported player by RB. I am dreaming with this :-) :-) I think we have the technology, knowledge and human forces to do that.
IMPORTANTE:
I got attention from http://www.embedded-projects.net/, they sells USBprog assembled kits and others circuits. I think that they are connect with http://www.in-circuit.de/.
I leave a message in theirs forum and i got a "sounds interesting please send me mail" - http://forum.embedded-projects.net/viewtopic.php?id=140.
I would like to get advices in what could I say on that e-mail. I would like to attract them to build and If possible to help in hardware, they should have experiencie.
Thank you.
