    Thanks Sc0rian,
    the LCD was bought from Modwarehouse because I was not able to find a blue LCD in Italy. It was quite an adventure, but at last they sent it to me... They're having a lot of troubles with their site in these days....

    HDD/DVD TRAY

    The mounting of the HDD and DVD-ROM was the trickies part of the project, but I was so lucky to get all the parts fitted with a little work.... :)

    My first idea was to use the RAM module and an edge on the front panel as a base for the tray; I made a rough test with a piece of plexy and found that I had to stack the things in this order:

    Code:
     
    ---- DVD-ROM
         ---------- double sided tape
    ---- HDD
         ---------- screws
    ---- plexy
    
    So I modelled a plain tray for the HDD and drilled four holes for the screw:

    [​IMG]

    Here is a test of the tray in its place:

    [​IMG]

    [​IMG]

    I tested the position for the DVD too:

    [​IMG]


    Everything seemed ok, but I have one problem here: how can I fix the tray to the box? The first thought was to use some double sided tape on the front panel edge and on the RAM.... really quick and it can work surely, but it's not so good if I have to remove the tray for maintenance......
    So I started to look at the box and I found a nice hole that could hold the tray in its position; I made a little bracket and glued it to the base tray:

    [​IMG]

    and tested the new tray in the box

    [​IMG]

    PERFECT! :hip:

    So the last test was to fix the original cd door to my slim DVD and put everything into the box. I was so lucky that the door locked exactly onto the DVD tray

    [​IMG]

    I had to drill a little hole into the door to get access to the eject button (the opening of the drive will be software controlled, but it's good to have the possibility to eject manually if something goes wrong!)

    [​IMG]

    Finally, the drive was placed on the tray and this is the result:

    [​IMG]

    I think it's quite good! Now I have to fix the power switch, connect everything, check twice all the wires and turn on my new Philips CD/MP3 player!!!! :thumb:

    Stay tuned..

    Hey this project is superb, you're obviously a very talented modder and Linux guru!

    Quick question; Can you see the LCD through the smokey glass on the front of the CD player or will you be cutting a whole for it?

    Now installing Linux on my 200Mhx :D very tricky to do this :eeek:! But i'll hope the system will run. I think i forgot to add the modules could i add these later? or do i have to re-install the linux core :worried:.
    I'm using this guide to set it up: http://www.tonywhitmore.co.uk/core/coreindex.html.
    papeniglio you've got your sys already running? I prefer windows because it's lots of easier to install, but it doesn't start as fast as linux does.

    Sorry for the delay... I've lost my 2 Mb/s internet connection this week-end, so I couldn't read the forum; working to set it up again...


    The LCD can be seen very well through the smoked plexy, so the original front panel will be kept unmodified.


    You can add modules whenever you want, provided that you have activated modules support during kernel configuration. On this distro you can use insmod to run your additional modules.

    And yes, my system was running before starting to mod the Philips box and it's running with no problems. (I must suggest :read: !!!)

    FINISHED! Let's the music play...

    I've finished the hardware part of this project; I've fixed the DVD player, the power switch and closed the box... Here is how it turned out:

    [​IMG]

    I'm looking for the original plastic cover for the power switch: I know I have it somewhere, but my room is too messy now, so I'll let the time reveal that treasure!!!

    When I powered on the box, I noticed that it was too loudy, so I removed the cover and tried to find which of the two fans was the most noisy; I reduced the PSU fan voltage to 5V and now it's really quiet. The box is running since saturday with no problems and there are no heating issues...

    Here is a shot with the DVD tray open:

    [​IMG]


    And now the software side: here is the telnet session from my lap:

    [​IMG]

    You can see why the system is so light:

    [​IMG]

    only the bare essential processes are running, resulting in a very low memory usage.


    When the system starts, LCDproc welcomes you with this screen:

    [​IMG]

    I will try to mod this making it display a more kind welcome message for some seconds, and then it will be ready for audio playing.


    A quick adjustment of the audio levels through alsamixer

    [​IMG]

    and I'm ready for my MP3 test:

    [​IMG]

    here is mpg123 playing an MP3 file; you can see how low is the CPU usage from LCDproc:

    [​IMG]

    Only 10.7%!!! I'll have a lot of power for the jukebox application.

    Finally, I tested the remote control with irw:

    [​IMG]

    all the keys on the remote are decoded and I can assign them any function....


    OK, that's all for the harware setup.... Now I'm evaluating some jukebox applications: I've started with IRMP3, but it doesn't satisfy me at all; I'll try Cajun because it's web based and makes use of MySQL and Perl.... it could be useful for other functions, too...

    Thanks to anyone who read this thread and hope I've given you some ideas to put that old crappy A/V stuff to a new life!!!

    Love the result really i do! :D trying to configure my own linux system aswell, very still very hard 2 do i think! :worried:. But is it also possible to switch between mp3's with your remote? (maybe a :wallbash: stupid question but ine the example you play an mp3 file you must give the filename you want to play). Is it possible to browse your library with the remote?
    But again: I LIKE THIS JUKEBOX! :clap: :clap: :clap:

    Very nice work. I'm about to do something similar. I've got an old dell workstation 400(p2 300 with 256mb of ram) that I'm going to put in an old cd player that decided to start eating cd's. Only problem is it's a cd changer and has a big rotating drawer - taking that out and still looking decent will be a challenge. I hope mine ends up close to as good as this one.

    Have a look at IRMP3 home page; you can organize your music collection and you can navigate through files with your remote; mpg123 is called just for playing the file you choose, but the main control is IRMP3...

    In the example I was running mpg123 from the command line; IRMP3 was not running, that's why I couldn't use the remote to change song.

    Now I'm compiling Cajun.... Want to test this.....

    Thanks and don't be scared by linux! :rock:

And really i love linux my 200Mhz starts within 10 sec :rock:.
