New version of ARMopendous boards, more details for planed Lyre hardware (edit on 21.08.2009)
We are working closely with ARMopendous, since he is designing the Lyre boards and on final he will produce and sell them online. Here are the last message from him:
The rev2009-05-12 version of the ARMopendous was a significant learning experience. The next version of the ARMopendous, the ARMopendous-DIP improves on the design and provides very flexible and cheap High Speed USB connectivity. A second variation of the ARMopendous, the ARMopendous-DAP, will be a high quality audio player. Schematics for it are available but the board will be routed once I figure out how to create matched-length traces in KiCAD. SDRAM was a major problem in the rev2009-05-12 of the ARMopendous. The schematic for the ARMopendous-DIP is also available. PCBs for it have been ordered and a prototype will hopefully be created before September.
The ARMopendous-DAP board is being designed to fit on the plastic case Hammond 1553B:
(c) Hammond.
While the ARMopendous-DAP is not available, we will be able to work with the ARMopendous-DIP version, at least an initial Rockbox port for having the kernel working will be possible, for flashing the on board LED.
Here is a 3D view of ARMopendous-DIP board:
Schematics sources for ARMopendous-DIP and ARMopendous-DAP are available on SVN ARMopendous page.
Lyre project website now ready (edit on 10.06.2009)
Lyre website is now ready: http://lyre.sourceforge.net/
I had to install again the Drupal because Alex Cantos is busy and away from the project, I had to remove the last install made by Alex.
Now site have a blog, a forum and pages for collaborative writing just like the wikis :-) On next days I hope to put more information about the project on the site.
ARMopendous boards now working!!!
Matt made it, he designed the 4 layers board with KiCAD (Free Software), designed the solder paste stencil, assembled the components by hand and finally did solder them on cheap toaster oven - all at his home!! Matt is my hero ;)
Here is the image of the board:
See here more details about the production and assembly of the board (DIY).
Now Matt is looking for help on the DAP-Expansion board, he will soon send the files to produce the board. Please everyone give a look at the schematics and see if something is wrong or missing. Thank you.

- LCD
- Audio CODEC

--- Quote from: Mad Cow on September 28, 2006, 10:32:17 PM ---You can get PCB's printed? I thought that was just for huge orders from big companies. The housing wouldn't be too hard, check out the projects on http://www.benheck.com. I still think writing firmware would be the hardest, because you can't get much more than rockbox devs anyway.
For the future I would recommend a dual-core CPU, because I've read that will be the fastest way to decode video and audio without an external chip. The problem is, nobody knows how to use both cores yet.

Yeah, I'm too lazy to see if anyone else has answered this question. That said, there are several quick turn PCB companies that can turn out small quantities of PCB's very cost effectively. in the neighborhood of $25-50 each. Advanced Circuits and Express PCB to name a couple. Advanced Circuits even has a student program with $33 two layer PCB's with a minimum order of 1.

Hans

Me and Bob, we both bought the Friendly ARM mini2440 development board. Schematics, datasheets and example code as Linux, are avaialabe here.
We bought the boards on Ebay for about $85 (with LCD and touchscreen + jack audio output) plus shipping.
We were looking for a way to have a repository of firmware where we could store our Rockbox port and at the same time keep it updated with the Rockbox SVN, to be able to create patchs. The best way we find were to use Mercurial on Lyre SourceForge.net project space. I wrote a quick instructions page for how to view the code, get it or commit.
We were able to create the structure on Rockbox for our port and now the Rockbox bootloader builds without errors. The code is a copy of the Gigabeat port, since it uses the same ARM9 SoC.
Next tasks is to learn and try to rewrite the C Startup code and Linker Script, so the main() on bootloader file can be run. We also need to get the OpenOCD script file for loading/debugging the code on SDRAM.

Next picture were taken by Bob. Note that LCD can be mounted in many ways, it can cover almost all the board as seen on this picture.
Two others Rockbox developers bought the board, Domonoky and JdGordon. We should see a big push on this hardware soon ;-)

Western Digital has introduced a 750GB 2.5" SATA HDD. I've been reading through the posts. Is a 2.5" SATA drive a consideration for this project? I've seen postings concerning 1.8" ZIF drives but those are still very limited in capacity and expensive. 2.5" drives are plentiful and relatively cheap.
It would be nice to have one's entire FLAC collection to carry about.
Just a thought.
