Rockbox Player - Project to design and build a Free/Open hardware audio player

<< < (10/144) > >>

alsaf:
Thanks. I thought it was possible but I didn't realise it would be possible with 3.5 inch drives although it would be external to DAP.

I noticed there are multimedia players like the MVIX MV5000 and IAMM NTD36HD would be ideal for my needs but AFAIK  they don't support lossless formats and from what I see of screenshots the UI doesn't impress me.  

Rincewind:
An iRiver H1xx could be the basis for a high quality non-portable HDD-Player. I imagine using a huge standard 3.5" disc and building a custom case with buttons and the iriver LCD on the front and the audio and optical connectors at the back.
The result would be a perfect addition to a home stereo system (or even in a car). It would have lossless audio, all the disc space you want, digital input and output, line out and line in and of course Rockbox.

The only problem is, you have to sacrifce an iRiver for it. If I can get a broken one on eBay I might start this project.

Kramdra:
It should be very possible to make a good player, which can support most if not all of the features in rockbox.

* Size - if the pcb was made by a prototyping company we could easly use very small components.
The big components would be the problem (harddisk and battery)

* Case/enclosure - plastic/aluminuim. wouldnt look as good as commercial products..

* Video - Not sure if commonly available ARM7 micros are powerfull enough for this, I dont know enough about them. video isnt THAT important, but whats the point in making a custom hardware if itcant do what the others can, yet still be more expansive? :)


I have done some very basic research into parts, and found:

LCD's: I thoguth this would be a problem since I have only seen large ones on electonrics shops however there are plenty of very cheap nokia 3310 ones on ebay which include a controller, it would be very easy to use on any micro and many people use them on pc serial ports.
There are also cheap colour ones. I found http://store.earthlcd.com/RNH942209R1A?sc=7&category=427 but there is probably a lot of cell phone replacements that would be better.

This one would be awesome, and its cheap too, http://www.sparkfun.com/commerce/product_info.php?products_id=712# (although Id rather have a gigabeat x30 screen...)

Processors:
I think an ARM core would probably be best. They are used in almost all embedded devices and seem to be cheap, easy to develope/program (usb/parallel/serial port JTAG programmers also cheap)


Decoder/DAC - Havent found out much about these. The  Wolfson WM8751L used in most players doesnt exist on their site and minimum order of 100pcs..
There is the VS1002 chip but I dont know enough about them, is it used in any commercial players?

It would be cool to use an accerlerometer for menus (like a Wii controller) but  maybe not a good idea for a hdd based player :/

gnu:
If you want DACs: look into your old DVD player, and you'll surely find one. If you're lucky, you'll find documentation for it!

Kramdra:
I cant see how a dvd player DAC would be much good for what we want...



I have ordered a STR710 FZ2T6 ARM to play with. If I can get far with it, then I have a spare wolfstone decoder from my karma which I could possibly reuse (its one of the few non-bga chips in there :D), the hdd and I would like to use a nokia colour lcd (6610, controller included). Im going to play with the lcd first and try to do other cool stuff with it - it would be very difficult to get it all on a small enough pcb anyway.
