C1000/3x00 Hardware / Keyboard Replacement For Zaurus C-1000

« on: January 08, 2009, 08:12:55 am »

I have a problem with my C1000 keyboard. Some keys do not work. I have to press hard several times on those faulty keys to make it react. I disassembled C1000 and found the flexible film keyboard inside which need to be cleaned (i tried without much success) or replaced. I wonder where can i order the replacement for it online? Tried most obvious sharp urls without any success.

"Cleaning" is the worst thing to do. You just clean out last of the conductive material.

I have restored some remote-control keyboards by supergluing tinfoil on those conductive pads under each key. That
was quite easy to do.

Complete Opie-sh script.
Copy it to /home/QtPalmtop/bin/3G-sh and then you can do start/stop from one Desktop icon.

Code: [Select]

if ps -A | grep pppd;
   then
    opie-sh -m -M "Kill the Connection?" -1 "NO" -g
    if  [ $? -ne 1 ]; then sudo killall .pppd; fi
else
if lsusb | grep 1003;
  then
    sudo rmmod usb-storage
    sudo modprobe usbserial vendor=0x12d1 product=0x1003
    sleep 5
    if  dmesg | tail  | grep "attached to ttyUSB2";
    then
        sudo /usr/sbin/pppd call h3g
        sleep 5
        sudo cat /etc/ppp/connect-errors | tail -12 | opie-sh -f -g -t "Connected " -m
    else
        opie-sh -m -M "Replug the Modem! Wait for blinking blue light." -g
        . 3G-sh
    fi
  else
    opie-sh -m -M "Modem not Plugged." -g
 fiMy sudo is simply: su root -c "$*"

interesting... how do you charge up that battery?

-- It is of course removable. It is one of my camera batteries. I have chargers, also a solar charger for that.

I have not read all the posts in this thread, but it looks like none of you have managed to actually use
the Huawei in Zaurus?  

I have standard Sharp Rom and usually it recognizes the device only as storage.
Then I simply kill the usb-disk and create USB-ports myself:
 
rmmod usb-storage
    modprobe usbserial vendor=0x12d1 product=0x1003

Sometimes I have to connect USB-line twice and execute the script several times.
The device is connected properly when there are THREE new serial USB-ports in dmesg.

Thereafter the device is just a modem in /dev/ttyUSB0  

Me myself copied and modified these scripts:

I have a usb device that requires more power when pluged into the zaurus. I still need to be mobile so I'm wondering if there are any goot battery powered usb hubs out there that will add the extra power needed to allow powered usb devices to work?  Does anyone know of any?

All you need  is 5 Volts (max)  connected to the USB power pin.  This lthiuem-battery produces 4 volts and it seems to be
sufficient to power most power-hungry devices I have.

hello
i'm thinking about a umts/hsdpa modem for my zaurus.
as all CF modems are only gprs, i'm thinking about an USB HSDPA modem :
http://www.huawei.com/mobileweb/en/products/view.do?id=282
do you think this can work with the zaurus, i mean about power consumtion and modem drivers ?

Yes. Except you need more power. I have a camera battery (4 volts) is directly connected to the
5 volt USB-line. Does not consume much, but there are 300mA power burst that Zaurus cannot
produce.

C1000/3x00 Hardware / Usb Host Cable Redesigned

« on: December 04, 2007, 03:59:43 am »

You might be interested in the following usb host adapters
http://www.wolf.ne.jp/syuhen/zaurus.html
The 3rd, 4th and 5th ones do the same as your adapter.

I also was thinking of making one of these, but the result would had been thicker. There is also the issue
of odd-angled twist caused by these adapters, which might damage the zaurus.

BTW, it is perfectly possible to make an adapter that is perfectly flat using flat cable. You could
glue Bluetooth adapter semi-permanently someplace.   In  C1000 there is room
for that also inside.

C1000/3x00 Hardware / Usb Host Cable Redesigned

So you just dismantled your host cable for the parts, I take it? I've looked a bit, and haven't seen USB plugs for sale anywhere.

No, the miniplug was from a regular surplus camera-cable. Zaurus thinks now the plug is from a host-cable, because the pin #4 is connected to the pin #5 and not because the plug is fatter. Real host-plug is fatter, because it prevents pushing it into a non-host device ( a like camera).
As regards to the regular-sized female-USB-connector, you can find them anywhere, it took mine from a broken computer.

I agree. Any hope of a how-to? I suspect it's just a matter of connecting the correct wires and pouring hot melt on it, but it'd still be nice.

Thats about it. Only problem is that those wires are so tiny, that you need to be sober when eliminating all excess parts in the connector.
As regards to what wires to connect, it is explained before. A Mini becomes Host-Mini, if you connect the unconnected contact to the ground-wire.
They are sitting side-by-side and ground is #1, so it is difficult to make a mistake.

My connector looks much better now, I used black rubber cement to disquise the hot clue.

This is how the Usb-host should have been made. Now it does not stick out from
the side.
Now I can keep Zaurus in waterproof bag and use usb-GPS while kayaking.
