Just wondering what the 5 metal spots running down the lower rear right side of the phone are for? A rapid charging dock??
I believe that's the dock charging contacts

Pogopin docking
On a related note... I noticed that the HTC Car Dock does not have the contacts for the pogopin. How does it know to automatically launch Car mode when it's inserted into the dock? Are there embedded magnets or something?

No there's something in the usb cable that triggers it, like an extra lead or something.
The car dock will not use those pins.
The car mode is trigged probably by an resistor between pins 4 and 5 in the USB cable.

Just wondering if anyone knows the pinout for the 5 contacts on the back so i could make myself a speaker/charger dock until an official one becomes more available.
I've wondered this myself. After running a meter across the pins. Pins 2&4 seem to accept a voltage pin 5 is a ground I think. I feel through a guesstament that it follows the USB pinout in flat lateral form.

Usually I would literally just test each pin to see what was what but obviously being an expensive phone and canceling my insirance I do not want to short anything out, and yes it seems logical for one of the end contacts to be a ground, did you put a voltage into pin 2 & 4? If so how much?

I've been getting read to cut an older USB cable and test that way. But I used 4.4 volts. I to don't want to kill the warranty by ripping the phone apart. After I cut the USB I'm going to make a jig and do tests. If I find anything out I'll post here.

It's the micro USB pinout in pogo form..
1. 5vcc
2. Data -
3. Data +
4. Audio out mono
5. Ground.
Left to right pinout with the camera facing your left shoulder.

Thank you, I shall post a pic of homemade dock when I have the time to make one.

Ok. I tested. Connected HTC ONE X to lab power supply (5V 1A limit) and after a while (2-3 seconds) is started charging and 0.44A was flowing into phone. It was almost fully charged at the time.
Does anybody know how to get audio out on audio out pin?
And why Data - pin has 1,8V in reference to ground at all times?
edit:
Ok. I measured again. 0.44A and phone goes to charging (USB). I don't have time today to see what happens if you connect Data + adn - pins...
But still no luck with audio.

hey guys you can check this site out http://techno-fix.com/ . i found my pinout searches there. there are very usefull things
hey guys i just had this thing in mind...many a times my hands get a bit sweaty or its very habitual for me to kinda use the phone wid wet hands..
can the contact with the docking pins cause any issue?
I am installing a tab 2 7 as a permanent fixture to my car dashboard. I would like to charge the tablet in ac mode when the ignition is on and, trickle (USB) charge while the ignition is off.
As well as saving my car battery, this will also be my trigger for tasker to activate / deactivate the display.
My question is this, if I use a relay to short the two data pins on the USB cable will this switch to ac charge mode.
An alternative may be to use a standard Car charger and use a relay to break the continuity in the middle cores when the ignition is off

I'm going to be attempting the same thing with a Droid X I'm using as a DVR in my car. Any updates? According to this, once AC charging is initiated, removing the short will not revert the charging mode back to the lower rate without interrupting the connection.

I haven't had a chance to look at it yet. But this sounds like it may put a spanner in the works. I may have to rethink

I'm still waiting on the boat from China for my parts, but had an idea in the meantime. Perhaps a second relay to simply interrupt the +5V wire (and a capacitor to add even more of a delay?) would do the trick. I'm no EE, but it seems like this may do the trick.

The basic principal doesn't work anyway. No matter if the d cores are disconnected

My new plan is to switch in a resistor to trick the Tablet into thinking it's docked. Then use this to trigger events in tasker

@KrisPerry - Can you elaborate more on how to accomplish this with the Galaxy Tab 2? I have seen threads on how to do this for the S2/S3 with the micro USB connector, but nothing for the the Galaxy Tab 2. I would be very interested if this works for you.
Cheers!

Ok first I ordered the breakout board from http://www.podgizmo.com. this allows components to be soldered directly to the relevant pins.
I simply used a 33 and a 10ohm resistor to give approx 7.5 ohm resistance. When the ignition is started a relay switches the resistance across the deviceID pin. The Tablet then thinks it has been car docked and subsequently runs a specific tasker profile

@KrisPerry - Brilliant, this is exactly what I have been looking for. Do you already have this working? Just to confirm, is the deviceID pin you reference pin 13 (ACCESSORY_ID)?
I'd love to learn more about your setup if you have it documented somewhere (I didn't find anything on XDA).
Cheers!

Correct, between pin 13 and ground. I have it working on the bench. Next step is to test in the car before installation. I'll maybe document the whole process once completed

First of all sorry for my bad english
The things that you need to fabricate charging dock are as follows:
1) Old CD case
2) Old sony ericsson data cable
3) Some fast glue
1) Disassemble CD case in order to use only the back side
2) From data cable remove plastic fixing legs
3) Mesure with the phone and mark the correct position of the cable ( the picture of the cable should be upwards)
4) Using some fast glue bond the connector to de CD case and voalla the dock is ready
And hese are the pictures. Maybe tomorrow i will make it like stand but for now is working ok for night charging

Yeah, nice work!

It works! But, what's the voltage? Isn't it low?
Why would the voltage be low? USB is a standarized port so there's no difference between chargers when it comes to voltage.
The other thing is the current that varies from 500mA (USB 2.0 port) and 900mA (3.0 port) up to 3mA. The current depends on the charger not the cable.
I tried making this and the charging time takes a long time. I am gaining about 10% per hour. Is this normal?

Depends. Which charger do y use, more precisely how many amps does it output? Maybe you contact surfaces are to small. A pic would be welcome

I don't think the charger has any effect, I believe the pins are set up to draw a maximum of 1A, probably due to it being a dock, it wants to "slow" charge.
As for it taking a long time, I found that the cable had a huge effect, switching to a better cable made it charge correctly.

I am using the stock charger. It would probably be the contact point. I don't want to scrach my XZ so I didn't push it all the way down. I'll try again when I get home

Ah, correct, wiring, to small section causes more energy loss. So taking a thicker wire isn't l luxury. But standard usb wire should work.(I used a Sony Ericsson fastport data wire)
Could also be the soldering, if it isn't sold properly you get bad contracts.
I'm using a 750mA charge ( from the x10) and it never takes so long to charge even over my custom system running a sleep taking app over night.

Does anyone have any ideas because I found an old DIY speaker and I was wondering if anyone had ideas for a dock in which it could be used.
Sent from my C6603 using xda app-developers app
I wanted the same dock+speaker end result so I ended up using my BT speaker and using tasker (but can use smart connect) to auto on BT when docked which it then reconnects to speaker when in range then turns BT off when undocked. Obviously totally different than wjatbtou have to work with but I already had the speaker so it cost me nothing to do.

Hi, I would go with something like the attachment. Using a sbh20(or similar) for wireless sound transmission. Speaker on the side. ( if you thing is stereo, one on each side), and the phone in landscape mode on a inclined surface with the pins on the bottom.

How is this one supposed to work? You plug it into your USB port, this part is clear, but then? Do you somehow stick it under the cover? Or just stick it on the back side?

It's still in transit, expecting this week.....
Ah OK, cause I'm thinking of buying one too, and there's currently a 5% discount
The only thing that bothers me is to Sacrifice the micro USB poort. I don't like that but What can you do.......
So I bit the bullet and bought one and a charging pad. Let's hope they work!
And about the USB port, I thought you'd still be able to use it cause it seemed like it would still allow the cable to go through. Well in any case I only use the port to charge my phone, everything else is done via WiFi
Actually there are 2 questions:
Is it possible to put it under original cover?
Are camera, flash light and speaker OK with this?
ok, the adapter does fit for use inside the phone, although I had to file out the USB port entrance in the back cover. That being said, it won't charge properly due to the layer of foil inside the back cover I presume. It sits now between the phone's back cover an the external silicone cover. Wireless charging is go!
awesome cant wait to try this and build a charger in every table
