Subject: RTC-Mod and 8-MB Mod.
From: Dario Carluccio (rockbox_at_carluccio.de)
Date: 2003-01-28


Hello Rockboxers,

i did it.

8MB Mod: In a Mail from November 2002 I saw in the Mail from Matthias
Wächter [1] in the Mailing List where he described his modification.
So I asked a friend, who does Ram Mods on Palm-Pilots if he could do
this mod for me, as i never soldered on SMD. So I gave him my jukebox
recorder on December, 5th and he did this Mod in a week for me.

But the German-Post lost the packet on the way back home to me, and it
arrived finally on Saturday three days ago. So first I compiled the
Rockbox with the 8MB Mod-Option and really there are 8MB in the Box,
7. MB for MP3 Buffer :-)

But now I opened the Box to look at the Mod and to apply the RTC Mod
described by Uwe Freese [2].

So to open the Box is very easy especially if you use the description
disassemble the archos from the rockbox homepage [3].

The Ram Mod was made exactly as described by Uwe Freese [4], my friend
did a good job, you can see the pictures on my page [5]. But he said
that it will be take about one hour do do this Mod and he won't do it
again for anyone, because normally he had to take more than 100 EUR to
do this work.

Lets talk about the RTC-Mod [2]:

The biggest difficulty by applying this mod was to to de-solder the
left metal angle. I spend more than one and a half hour to do that.
Does anybody out there have a good trick to remove this f******
metal angle?

So applying the circuit not very difficult. I tried to bend op an
SMD-Pin on an old SCSI Card two times. So with a little practice i
lifted the Pin 14 up and applied the Cable.

My only error was that I assembled the Transistor with the two
Resistors an all cabled before, but it is easier to sold the cables
first to the jukebox and the to the circuit, so you can find a way for
the wires from the Soldering point to the transistor.

So I compiled the code with the -DHAVE_ALARM_MOD in the EXTRA_DEFINES
and the Mod is doing fine

Now I have a few suggestions for this Mod.

First I will describe my proceedings:

When I go to bed I hear some Audiobook or Hörspiel (I don't know the
English word) If it is finished the Archos turns off automatically.
In the morning I want the Jukebox to wake me up with a song or playlist
or MP3-Dir at an other Volume the the night before.

So it would be perfect to make a Wake-Up Setting such as:

   Wakeup-Timer: off(0) / once(1) / ever(-1) (alternative a counter)
                   0 / 1 / -1 / 2-99
   Wakeup-Time: hh:mm (time)
   Wakeup-Action: /songs/song1.mp3 (one Song, maybe repeat) or
                   /lists/wakeup.m3u (a Playlist) or
                   /albums/ramones/locolive/ (all MP3 in dir)
   Wakeup-Volume: 00-99 (Volume)

,----- [ Archos is turned off ]
|
| IF Wakeup-Timer not 0
| {
| IF Wakeup-Timer <> -1
| {
| Wakeup-Timer = Wakeup-Timer - 1
| }
| Set Volume = Wakeup-Volume
| Set ActualSong/List/Dir = Wakeup-Action
| Set RTC = Wakeup-Time
| Shutdown Jukebox
| }
'-----

Is this possible?
   

bye
   Dario
