Iterative reboots during the charge which avoid a the charge process. (N810/N800)


Try with different Nokia chargers, even with the same external aspect the voltages/current differs in the Nokia chargers, furthermore nowadays electric devices and since batteries have a broad range of input voltages there is no risk in this action.

Batteries or device have internal IC (integrated circuits), to protect the device/battery, and the problem could be there instead of the N8xx input.
For any reason the battery controller need more or maybe less voltage to continue charging.

You can use any mobile phone charger(the most of them are 5V-6V DC), you only need to change the output connector.

For N800 I used 5.2v and0.5mA (No nokia) instead of nokia (AC-3X) 5V and 350mA

Screen Jittering. (N800)

Device still working but it is very annoying to see how the windows are moving/jittering in the screen. I my opinion it is related with colour contrast in the screen because it happens more with dark screen than when we are working in a white/grey screen.

After opened the tablet I can see few components not covered by the metal shields but I saw two components which I think could be involved in the failures; battery(2) and capacitor?(2)

The capacitor is a bit dark in the lest side, looks like a bit burned, I hardly can read over it something like "G.MKT"




The battery looked bad but in theory should not affect to screen.


After disassembly the screen there some small components and two IC.
the small one has written "VM66BS 92300SN" (2)

Dictionaries and language reference on the road

(updated on 2013)

Best of reference and translation dictionaries for some of the following operating systems:
PalmOS, Android, MacOSX, Windows and  Linux

PalmOS


Although I always used my Maemo "PDA" to read reference information, in the last weeks I have been doing an intensive use of languages dictionaries in my PalmOS phone, and I realized that the applications/databases I was using had lacks in some aspects, I decided to found solution for my requirements, specifically phonetic symbols and pronunciation sound.



On the other hand, is possible to have and read Wikipedia in your device, there is no price for this free(as freedom as well) encyclopaedia, but your its utility is incalculable.

Dictionaries and databases



Download dictionaries from:

XDXF
and dictionaries with phonetic can be downloaded from http://code.google.com/p/ppdict/downloads/list

In desktop OS such as Linux, MacOS, or Windows, compatibility with database format is an important feature since there are many free language databases in different formats such as:
DICT (filenames .index and .dict (.dict.dz =compressed)
Startdict (filenames xx.if, xx.idx, xx.idx.gz, xx.dict or xx.dict.dz, xx.syn(optional)
)
XDXF (XML Dictionary eXchange Format)

Backup Firmware (0pen Free Fiasco Firmware Flasher)


DOwnload "0xffff" v0.3.9 from
http://talk.maemo.org/showpost.php?p=654646&postcount=3

0xFFFF.static.gz

(in order to execute the file 0xFFFF.static, you must copy it to a folder in the main partition (Not FAT/FAT32))


cp 0xFFFF.static.gz /usr/local/sbin
cd /usr/local/sbin
gunzip 0xFFFF.static.gz
chmod +x 0xFFFF.static
mkdir /media/mmc2/mybackup0xfff
sudo ./0xFFFF.static -e /media/mmc2/mybackup0xfff/




Now you have some new files in /media/mmc2/mybackup0xfff
config.bin
initfs.jffs2
rootfs.jffs2
secondary.bin
xloader.bin
zImage

you can put in one tar file.

tar -cf /media/mmc2/myN810backup.tar .
(for me it is a 262Mb file)
And I copied the file to my PC

Notes:
To extract from tar file
tar -xvf myN810backup.tar

EasyDebian On Maemo

A complete desktop PC in my pocket
Why? There are many technical reason to do.
why not? It is a easy procedure, there is no danger for your Maemo OS.

It is funny to see a linux desktop distribution running on our small devices, and there some applications missing in Maemo, and available with this way.
Using easydebian can be useful for some tasks, however the user interface wasn't designed for work in a small screen and you will feel tired after a time.



I think this instructions are easier than other available in Internet.
(tested on Nokia N800)

1 Install easydebian (aka Turbo Easy Debian for Everyone) from Maemo.org or Application (Maemo Extras repository)
1.1 You must chose menus for some access shortcuts (if you prefer don't mix with Maemo menu categories, you could create a menu 'debian' and place all this access links there)


2 Download on PC the following linux imagefile for easydebian
http://qole.org/files/
debian-squeeze-img.tar.bz2

3 Unpack downloaded file with 7zip, Winrar, (your prefer uncompress tool)
Unpack previous file to
debian-squeeze.img.tar
Unpack previous file .tar to
debian-squeeze.img.ext2

3 Copy imagefile to SD memory, for example to
//media/mmc1
You can copy in any format partition (FAT,EXT,..) and folder, you only need 1.3GB on target

4 Give the path of image to easydebian
edit /home/user/.chroot
write a new line with the path where we copied the imagefile
IMGFILE=/media/mmc1/debian-squeeze.img.ext2
(lines with # are comments)


5 Executing
Execute the app on menus (LXDE Desktop)
wait and now you have linux running

6 Executing apps without from Maemo Desktop (no need LXDE desktop)
From terminal(as normal user)
#debbie linux_app_name (e.g. keepassx)
(on N800 to show onscreenkeyboard, open Toggle Matchbox-kbd)





Config the environment
Onscreen keyboard are on main menu/accesories

Open a terminal and execute
sudo apt-get update
This command download info from internet debian repositories

Now you can install apps using a graphic way(1) or command way(2)

(1)Execute Synaptic (install manager) from a terminal with: sudo synaptic

(2) sudo apt-get install keepassx
(Keepass is an example of app)
