Modifying HP-keyboard to use with Wallaby - MDA, XDA, 1010 General

Hi,
I own exactly the same keyboard as shown at the bottom of this page:
http://wiki.xda-developers.com/wiki/Connectors
It's used for a HP 4150.
Now, I just like to modify it to use it with a Wallaby (O2 XDA).
The picture on the page mentioned above shows a connector that fits the Wallaby.
I already opened the case of the keyboard because I thought it was just a matter of resoldering some wires in the connector according the table mentioned on the page above.
However I found out that the connector is soldered onto a small circuitboard that fits in the connector, so I guess I need to have exactly the same circuitboard but then for a different connector.
Also, there are some wires that lead to the powerconnector on the left back side (wich is also mounted on a small circuitboard)
The powerplug of the Wallaby does NOT fit into this powerconnector so that needs to be replaced as well (including the small circuitboard).
And there is my problem:
Where do I get this connector (including the circuitboard that fits in the HPkeyboard) ?
I live in the netherlands so I think I need to order it somewhere on the internet.
Can anybody give me some advice?
Thanks in advance

Screen connector differences and rebuilding displays

I have a problem with my XDA2 whereby the 22 pin connector at the bottom of the device has become detached from the main board (after being dropped! outch!)
I have managed to resolder the connector back onto the board, however it appears that a couple of tracks have become detached from the board along with the connector which now means that the serial and usb ports no longer work!! - and there appears to be no way to tell where these pins connect to..
In an attempt to obtain a replacement board i have got hold of a damaged XDA2 from ebay which has a broken screen. However the connector on the board for the screen in this XDA2 is completely different to the one in my XDA2 making it impossible to swap the boards over (or the screens for that matter).
Does anyone know if it is possible to disassemble these displays so that i can produce a display that works with the right connector attached? I know that it's posible to replace the touch screen on these displays but i've no idea how - and i dont want to damage my working display!!
Any help would be apprecated

Brodit Powered Car Mount/Holder Question

Hi
Does anyone know if the Brodit powered car holder for the Wizard fits the Hermes? Similar width and thickness of devices suggests the Hermes may fit in the Wizard holder, but can anyone confirm one way or the other?
Many Thanks
Chris
Why don't you just ask brodit?
[email protected]
No, it doesn't fit.
Actually the USB plug does not fit because on the wizard it is located in the middle and on the tytn it is located at right side buttom side.
But the whole phone itself stays in place very good (the tytn is a little bit thinner).
I had the same problem and I just took(cutting it off) the USB connector of the holder and glued it back at the right place so the tytn fits in it. Sounds a bit messy, but it looks fine. The usb plug should also be turned 180 degrees.
I am using this since 1 year and it works fine.

[Q] HELP!!! broken black wire/connector inside HD2

Hello all.
While I was taking my HD2 apart to replace a cracked screen (glass digitizer) I accidentally broke the connector off one of the wires. The wire is black and a few inches long with a silver and round press on connector on each end. It attaches to the board that houses the vibrator motor and runs down the right side of the phone (if you were looking at it face down and partially disassembled).
Unfortunately, I lost the metal piece that broke off the wire (the thing is tiny!), so I can't just solder it back on. Any idea on where I can buy a replacement? I've spent about 6 hours today on ebay and google to no avail. Searching for "HD2 black wire" and anything similar is hardly efficient, but that's all I know about it.
Any help appreciated.
Thanks,
Chris
Good question, I think I damaged the cable to the volume buttons so it would be cool if someone has an adress where we can get spare parts except LCD and Digitizer..
this guy on ebay seems to be selling an HD2 in parts. you might find what you need here:
http://stores.ebay.co.uk/Right-Click-Enterprises/_i.html?_nkw=hd2&submit=Search&_sid=131407386
Thanks, I sent that guy a message and hopefully it'll work out.
Anyone else have a source?
connector of my hd2 is also broken HTC says that the mainboard must be change and I have to pay € 230 because that is my responsibility
I think you have damaged your coaxial cable connector for wifi and bluetooth. Google will help you perhaps.
I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
if the connectors on the boards are not broken then all you need is the coaxial cable with connectors on the two end. you need not disassemble the whole set, just open the back cover, connect one end of the cable to mother board and other end to the rigid flex board and that's it.
WiFi and Bluetooth not working

Do you think that this is my problem as since I dropped my HD2 I have no wifi (unless sat ontop of router) or bluetooth or fm radio, is it easy to get to the coax cable by removing back cover, whereabouts is it ?

Fixed it, opened up phone and spotted that at one end of the black wire the connector was not pushed onto the motherboard securely, I pushed it home and hey presto, wifi and Bluetooth now working, phew, Thanks for your help !

[Q] Need help on how to dismantle Archos G9 80 16GB

I have G9 80 16GB Turbo. The plastic part of the inner micro USB feeder is broken and sticked out to the USB charger pin. My USB charger cable now blocked by that thing and cannot be use anymore. Now in the USB feeder of Archos just remain 4 tiny metals without plastic support (only 4 USB metal pins connector) and not able to take charge by anyway, it is bricked because of no battery power.
It is just 2 months old and no warranty since I bought it in airport transit. 3 times emailed [email protected] with no response as the world has suspected.
1. I've checked my Archos and did not find any screw other than single screw in the USB 3G compartment. I really thankful if anyone can write step-by step dismantle procedure.
2. Can anyone share the shape of USB type soldered to the PCB to enable me order the part and soldering it alone.
3. I've search this on thread : http://forum.xda-developers.com/showthread.php?t=1557506, but the information provided on how to dismantle is not very clear.
4. Thankyou in advance.

There's only a single screw at the back.
The housing is hold together by some plastic clamps and it is a pain to open the case (at least compared to a A101IT Gen8).
You really need some force and be very careful not to damage anything...
I'll post a few pics this week in a different thread, because i opened the device last week and it was little bit catchy

Usually this is not an easy task... at least for the unexperienced ones.
Be careful with the thin lines on that PCB.
To unsolder the connector you'll need a lot of heat because it is connected to the gorund plane of the mainboard.
Anyway i don't know the manufacturer, but i guess these MicroUSB connectors are all pretty similar.
So try to catch one, wherever it is sold.

You should start on the opposite side of the connectors and use some plectrums (used by guitar players) to lift off the plastic clamps.
As i said i'll prepare some pics...
EDIT: Here's an overview on how i opened the case.
As already stated it was a pain, and though i had been very careful, some tiny plastics got damaged.
The red circles mark the plastic clamps and the holes they were stucked in respectively.
The green arrows mark the direction i slided my guitar plectrum.
In between you'll have to use something like a screwdriver or putty knife to lift the clamps from their counterparts (this was the evil part).
In the end lift the top of the housing in the yellow direction.
Please take care of the flat cables of the TFT display, don't rip it off!!!

scholbert,
I don't know how should I thanks for your detailed information and photo on your reply.
Below my comment:
1. There is no abuse on the USB port (even no single scratch or dent to prove the abuse, from new I feel it is really tight when I connect the cable into the port, finally the plastic part comes out "cleanly" along with the USB cable connector when I unplug. That's way I try to bet the warranty honor...ray.
2. I've checked eBay and I find many type of micro USB port selling.
3. Based on the generous help you've written I will try to dismantle my Archos when I have spare time within this week.
4. If I may ask, for what purpose you dismantle your Archos. And did you find any problem something like not properly tight when you remantle it again?.
5. From the picture, are all the clamps just on the display side, or mix up and down between the base and display?. Appreciate if you can post the zoom picture of the clamp and the hole to know it's anatomy to make easier when pushing during dismantle process. I also seeing 4 screw-like holes on 4 corner, are they also something like alignment clamps without actual screw?.
6. Big thankyou again for your response.

I don't know if i got a second edition device, but i realized this screen issue as well (pressure on the back causes effects on the display).
So i thought i may open it and try to solve this issue.
Anyway i always like to investigate on the construction of these devices...

To be exact, the clamps are located all on the base unit.
The display side got the holes for the clamps. I'll see if i could make a more detailed picture, to point you in the right direction.
Though i'm not sure if it helps.
The srew like holes you pointed at are for alignment only.
I also found some glue in the holes, but this is no problem.
Some words on seperation...
It worked out like this on the long side of the housing (upper and lower):
- I tried to seperate the display part and the base with the plectrum step by step
- tried to locate each clamp step by step
- then used a screwdriver
- tried to press gently against the clamp, direction outside to inside
(be very careful and the long side at the bottom, because of the display flex cable)
- then try to lift the parts more and more (it's terrible, but it works)
- keep an eye on the torsion of the display side
(seperate the parts too much, might crack the screen)
I guess i'll prepare some more pics...
Stay tuned!
scholbert
You are really a man god sent to me, thankyou so much. I'm really itching to do the job. First thing I will do once dismantle completed, is to wire two lines for temporary charging until the part I order arrive. If by any chance impossible to replace micro USB port, then I will make hole on the base for common round type DC charging port + and - only.
Hey cangguek,
as promised, here are some detailed views of the clamps (base unit) and holders (display side).
The are four holders in total with two holes each.
The holders are seperate parts and are mounted with three screws in the display part of the housing. Each holder fits into two clamps of the base unit.
Unfortunately they can only get disassembled after you managed to open the housing.
The edge of the clamps point to the border of the base unit housing.
So you may try to push them gently to the inside to release the mating part at the display side.
Anyway i hope things are clear enough now...
Some words on your idea of soldering a DC charging port:
Electrically this would work i guess, but there might be some driver issue which could prevent the unit from charging.
It depends on how the charger is identified by the software driver, which activates the charging process.
On some devices it is required to shorten the data lines of the usb connector, others use the id pin on the micro usb to detect wether a host pc or a wall charger is connected. I don't know how things are done on the Archos 80 G9.
I just wanted to point that out before you start soldering...
Good luck!!!

-Data lines are not shorted, charging cable is a fully functional usb cable
-There must be something done to 4th (unused) pin in micro sd plug so device can detect Archos/"normal" cables (my guess- check data lines->if usb host not present check 4th pin->original=fast charge/3rd party=slow charge)

Yeah i know that the data lines in the cable are not shorted.
AFAIK, they get shorted when connected to the wall charger.
I own a Milestone phone (which definitely requires the lines shorted for charging) and i successfully used the Archos wall charger to charge this device.
At least i wanted to point in this direction...
Thanks for your comment.

-data lines are shorted together in charger (not to gnd/vcc)

Dear scholbert,
All the process as you said really a devil. I am stuck here (at red arrow) and can not proceed unless I tear it with force. Seems there different clamps ?.
Now I am stopping the the job waiting your further help.

Yeah i know it hurts... but AFAIK all the clamps are identical.
Nevertheless i realized the same during disassembly.
Some of the clamps did release quite well, at some point i also was afraid i'll break the device into pieces. I'm sorry but i guess you'll have to use gentle force to get it seperated.
BTW, i don't want to be responsible if you damage something
Another warning at this point:
I even did break some small plastics during opening (in the mainboard area), but it doesn't matter in the end, because there are many clamps to hold the parts in place
Good luck!

Just to confirm the only screw I removed only the one under the stand stick, I hope I am not missing here. I am still not continuing dismantle process, but at least 40% of the casing has been opened.

Man..., wtf, bottom pin of micro-usb (for desoldering purpose) covered with external card slot...grrrrr,....
Please look at the usb pin inside the housing, only metal pins only remain, the plastic part were come-off sticked-out along with usb charger cable. Anyone would come with idea on how to trick my situation?. Removing external card-slot then removing micro USB port seems a big job to me. The solder were very-very tiny...
I have completely separated and disconnect the wires of my Archos, so I have two part now: the base and the display part.
Anyone asking specific picture parts of my Archos, I am ready to shoot.

I am happy to see these pictures as they confirm my suspicion. The usb charge port is only soldered on, no screws to hold it in place. That is not a proper mechanical construction and it is no winder it becomes disconnected with only a little use. I have sent 2 units back already which will no longer charge as the mount point has come loose. Number 3 broke too now and as they want me to pay for shipment again ( €50) I am thinking of fixing it myself in stead, but properly..
I have the same problem
Did you eventually repair this problem. If so were did you get the spare part. i have got the same problem. I think i might try returning to my supplier first.

BNTV650: Info on the quick connector (aka "pogo pins") used to connect to dock and keyboard (B&N Nook Tablet 10.1")

Hello everyone,
Motivated by my tablet's failing USB connector and the great difficult of importing an original B&N charging dock (I'm overseas right now), I decided to try and see whether I could DIY a charging connector mysef, that would connect to the "quick connector" in the tablet's bottom.
First the good news:
I discovered that a standard 0.1" (2.54mm) PCB header like these has the exact pin size/spacing to make contact with the quick connector. So, no need to "fabricate" a connector from separate pins.
I used a digital multimeter to measure voltage on the pins, with the tablet both on and off, and with a USB charger both disconnected and connected, and apparently pin #1 (counting from the left when holding the tablet in landscape mode and looking at its front) is +5VDC, and pin #2 is GND (pin #3 seems to be a direct connection to pin #2 -- they are always at the exact same voltage --, and pins #9 and #10 seem to be +D/-D, not necessarily in that order).
Now the bad news:
I connected a 5V power supply to pins #1 and #2 as above (ie, +5VDC to pin #1 and GND to pin #2), but the tablet doesn' t react in any way (doesn't light up and show the "charging screen" when powered off, nor shows the "lightning bold" charging indicator in the battery icon in the notifier when powered on).
I tried changing GND to pin #3 (see above), with the same lack of results.
The moderately good news is that my attempt did not "fry" anything, the tablet kept working the same as before.
Does anyone have any more info on this "quick connector", or perhaps a better "solution" to my failing USB connector issue (I would be willing to disassemble and replace the USB connector, but I've searched Youtube and iFixIt to try and find a how-to-disassemble video, to no avail. The best I could find was these "internal photos" from the tablet' s FCC submission, but it doesn't show how to open it, and I see no screws nor anything -- not willing to try prying it open at the seams and risk cracking the case or worse).
Thanks in advance,
-- Durval.
Durval,
I came here from your posts on the GitHub issue. You've done some interesting work so far!
It's interesting that you found the pins are just like USB. I wonder if the Nook uses some sort of protocol to negotiate charging over the Pogo pins, like Apple devices put a resistor across the D pins IIRC.
I know someone who's replaced the battery so they might be able to guide you with opening the device. Their discord channel is here (they also posted in the GitHub issue). You might be able to buy a cheap Micro USB port and solder it into the board.

It could be. I also remember that a long time ago (like, 2008) I had an original (pre-Android) Motorola Razr which wouldn't charge except in a computer or with Motorola's own charger. I was thinking of full-blow USB connect negotiation... but you are right, it could be just a resistor or something.
I'm just not too keen on connecting more 'stuff' into those pins by trial and error, specially the supposed D+/D- things... I've managed to not fry the device so far, but one never knows when one's luck is running out until it finally does...

Just keeping the thread posted: I posted a similar question on the Discord server linked above, here's what I got:
Ryzen5-3600 | iPhone 12 Pro Gold — Today at 9:13 AM​It's really difficult to open the Nook Tablet. Mine had a cracked screen so it was easier to open up the device. The screen is made out of this really cheap plastic, it breaks so easily. My guess is to get like a small plastic guitar pick and pry open the back.
[9:14 AM]
You might have to get like 3 or 4 for safe measures to help keep it open so it won't close shut again
So, I think it's better to refrain from trying and opening my Nook, at least for now ;-)
I'm trying to get a dock, when/if I get one I will open it and see for myself what the heck it does to make the Nook recognize it.
I will keep this thread posted.
Cheers,

Two years late to the party, but I recently purchased two of the 10.1" nook keyboard covers @ my local B&N for $5 each, to play around with. If my suspicions are correct, and this keyboard controller outputs USB, the first four pins left to right should be GND, (I assume D+, D-), then I assume VCC.
I might be wrong. But I'm fairly confident that GND is pin 1- continuity between the pin and the ground pin on the keyboard controller PCB.

Did you have any luck? I bought the same keyboard for $4 at my B&N and just tore it apart. Turns out it only uses 5 of the 10 pins. The white box in the pic was pulled off so it originally did fit slightly more forward. Hopefully you can tell where it's supose to go.
