Has anyone connected their Galaxy S III up to a Motorola Atrix Lapdock?
If I remember well, the Motorola lapdock uses a HDMI plug to connect with the Atrix.
GS3 doesn't have one, you should get a MHL/HDMI convertor. Don't know if it'll work as a native HDMI plug will do.
If someone have both, it could be intereting to see if that work
So I'm going to dust this thread off a bit because this is the project I'm looking to work on -
I've ordered an Atrix Lapdock for my Bionic (very simple mod to dock the bionic) but as my personal phone is an S3, I'd like to use the lapdock with it primarily while still having the option to dock the bionic while on the go (I carry both phones). (While I'm at it, I'll probably look to get an hdmi micro extension cable and usb-micro-male to usb-A-male extension and try and use the lapdock as the base station for the Samsung Slate 7 PC i barely use since the interface is so poor)
Here's what I've gathered by reading various threads.
Lapdock:
The Lapdock will work with any HDMI source as seen in other threads (ie connecting to a PS3 via hdmi female micro to hdmi male standard adapter, $4 part from dealextreme). Others have posted how they can use the lapdock as a self powered hdmi external monitor with their laptop (very cool usage btw considering it's size)
Droid Bionic:
easily docks to the Atrix version of the lapdock by simply rotating the hdmi/micro usb connectors 180degrees in their sockets since they're piped in with short cables.
Galaxy SIII / S3 (mine is the T999):
here's where it gets tricky.
As I've gathered about the 11pin micro usb port (on the S3 and shared by the Note 2):
the original 5 pin MHL standard was ditched in favor of the 11pin MHL type connection. this in theory would allow the use of hdmi output with simultaneous usb otg and charging capabilities.
reviewing this thread here: (showthread.php?t=1953061&page=2) one can see that an OTG cable was modded with a simple resistor to allow for charging - member triff (the OP) was able to get this going and noted the log he got when the cable was plugged in reported 'hdmi fail' which leans to failing to initiate an hdmi connection... later in the thread member MRBR7 alludes to having an hdd running to view while charging on the OTG cable - his post is a bit vague as to whether he did the mod on an OTG cable or an HDMI cable.... i'll have to follow up.
finally, the posts in this thread (first 12 pages are a quick read showthread.php?t=1741583&page=12) provide resistor values and some close ups of the boards for the 11 to 5 pin adapter as well as what I thought was a list of pins for the 5 pin MHL.
I'm really trying to be purposefully clear in this thread as to my findings because it seems there are too many vague threads out there regarding the functionality; simply missing a letter or punctuation in a thread can turn a sure thing into a vague post...
another avenue is the official samsung galaxy note 2 "smart dock" which has 3 usb ports, in additon to an hdmi output and charging input - since this is sold out in the US (and due to PAL vs NTSC Standard I am hesitant to order from germany) it'll be a while before I can personally buy and test one (unless i can find one locally somehow). this seems like the best bet for a dock which can be hacked or adapted to interface the s3 with the lapdock.
my ideal final outcome of this thread would be to have a small cable or interface box which i can plug into the s3 to enable hdmi output + usb otg + charging. that trifecta would connect via a single micro-usb to the device (11 pin) and have an output of a female usb (A or micro, either can be adapted) and either a male or female standard hdmi (again, both of which can be adapted). this cable could enable the phone to be used as an impromptu desktop, carputer, lapdock brain etc...

What do you mean by that?
The Atrix Lapdock is internally nothing but an 1366x768 HDMI LCD monitor with (rather poor) speakers and an USB-Hub on which a keyboard/touchpad and two free USB-ports are connected to. The monitor and the USB-hub have to be simply attached to any device which supports HDMI-output and USB-OTG via (slightly uncommon) HDMI- and USB-OTG-plugs.
There is no software running on the Lapdock (it is actually completely dumb) and there is no need for any specific SW on the connected device (might be nice to have something like webtop running but it is not necessary).
The S3 works flawlessly with the keyboard/touchpad/USB-hub using a USB-OTG-Adapter and with the HDMI-monitor via an MHL/HDMI adapter cable. The tricky part is only to get both simultaneously and possibly even charge the S3 from the Lapdock. For that purpose I use as long as there is no combined MHL-HDMI/USB-OTG-adapter/dock available (as described in the thread and page already indicated above: showthread.php?t=1741583&page=12 ) the allshare cast dongle and a cheap OTG adapter. You can use office apps, watch videos, play games etc. without any problem. You can check out

Well, I got the Lapdock for less than 70 Euros and I think that is really great value since it is very well build and versatile... the allshare cast dongle is a bit overpriced (currently it is about 55Euros here) for an adapter-replacement but if you need it for different use cases (I mainly have it for a small LED-beamer) it might be worth it.
You can charge the S3 from one of the USB-ports of the Lapdock using a micro-USB cable (as long as the dongle or any other device is connected to the Lapdocks HDMI-plug - that is what signals the Lapdock to power up), but you can not simultaneously use the MHL/USB-OTG then. So it is nice for watching movies from your S3 on the Lapdock-screen (btw. the sound works fine as well) while re-charging the S3 but for "office" work with kb/touchpad you have to replug the OTG-cable. Actually I'm quite impressed with the relatively low power consumption of the allshare cast connection - so that is not a real problem IMHO. There might be people out there to solder the right resistors into OTG-adapter cables to allow both...
One disadvantage is obviously that you have this "bulky" (it is actually lightweight but still bigger than a simple adapter) dongle on the Lapdock. The big advantage over a dock is that you can more or less freely move around the S3 while using this combination.

google 'bens outlet' (a 1saleaday company) and you can pick one up for as little as $50usd! assuming it actually ships out, but worth it for a spare monitor project at the very least... - and yes, not a hard setup at all - the first use in my mind would be just to have a full size screen on the go, however to have a cable capable of mhl/hdmi + usb otg + charging would turn the dock into a powerhouse android laptop using 4g internet etc... (it'll give the chromebook a run for it's money)

all very cool - I'm thinking of ordering the allshare dongle just to try this out until the smartdock gets back in stock to hack it apart .. I'll probably order an 11pin mhl in the meantime too. I have a 5pin mhl, not sure what I can do with it without the adapter (i'll probably bundle it with my galaxy nexus and sell it all)
@a32: on a side note, i broke down and bought a Note 2 yesterday haha, so I'll probably be continuing this project with the Note2, (tmo just happened to have some in stock haha) I'm putting my week old S3 up for sale soon, but this project is still on my radar!

The S3 would need the lapdock .apk for certain functionality... calm down, I've owned enough Motorola Android devices to know what I'm saying...

Its out of stock now but you can get the extenders separately at a hefty price:

Sorry to snap, but if you've been on enough forums, you begin to notice that comments like yours are just add to confusion when unsubstantiated.
Any phone without a 'web top' mode or apk would obviously not work similar to the webtop mode that Motorola intended, however it'll still work, perfectly in fact, because this connection project is akin to hooking up your phone to a tv or monitor and using a usb mouse and keyboard to control it, albeit it's portable, like the padphone.
If you have any ideas as to how one could hookup both mhl/hdmi and usb/otg with charging I'm all ears (the real breakthrough would easily be seeing a US version T999 or similar running with the Smart Dock for the Note 2
Another thought to throw out there is whether this finished product could look similar to the padphone concept: a pocket for the phone to slip into, docking connector inside, basically self contained
As for those extension cables posted, places like monoprice and dealextreme have much better prices and selection, granted I'm just going those links on my phone - i don't understand how those are considered 'adapters' when all they do is extend the port

You don't.
... that's what we posted already. The webtop SW on some Motorola devices starts a specific desktop and window-manager on your phone when connecting to the lapdock. It may facilitate the use of the apps on the phone via the Lapdock (resolution/size/... of apps in windows etc.) but you do not need it to work with the S3 on the Lapdock.
awesome! im very tempted to get one but in the UK they are still expensive

A bit off-topic: It is an ACER C20 I own for nearly 2 years now. Like this one:
ecx . images-amazon . com/images/I/41aXbNerVoL._SL500_.jpg
It is out of stock anyway, but I could "partly" recommend it:
It has the size of a phone, a built-in battery and - most important - lots of inputs (mini HDMI (HDCP), D-Sub (24-pin Universal), Composite Video/Audio (2.5mm 4-pin mini jack), micro USB (Typ AB), micro SD Card (SDHC)) + Audio out & speaker. It plays media from internal storage/SD card but that internal media-player is crap. It is however extremely mobile and together with movie players on modern phones like the S3+cast-dongle - or any tablet with HDMI-out or a device with Composite A/V out (e.g. old Nokias) - a nice device e.g. to entertain kids on travel or showing pictures while visiting the grandparents or alike. On the other hand, it is not really bright at all (actually you have to be in a very, very dark room to use larger screen areas) and the battery lasts often only 1/2 hour (but you can charge it with 5V from USBs or use it while on the mains adapter).
It works really nice with the S3 + allshare cast dongle (that's what I bought the dongle for in the first place), has a descent image quality (848x480 pixel) and accepts up to 1080i HD over HDMI as input signal for downscaling but for the dongle the input is of course limited 720p. It does NOT work with the S3 using the cheap (chinese) USB-MHL/HDMI-adapter with the long red cables (somewhere discussed here as well) since that one provides 1080p30Hz (at least to my TV - on which it works) and the projector obviously can't sync to that.
Back to the topic: that cheap HDMI-adapter for S3 works not very well with the Atrix Lapdock; you get an image but it is vertically squeezed. Again: the Lapdock and the S3 + cast dongle go together extremely well.
That led projector sounds pretty cool, I've waffle'd on buying one various times but can't say I've had a particular need other than for the fun of it hah

So I'm guessing you've tested this, but with the hdmi cable and the screen rotation turned on, the device still shows up in portrait? Unless I'm reading that wrong and you mean it's width wise video but looks like a 4:3 video on a 16:9 widescreen?
I wonder if that behavior is present with the official adapter...
So to return to the method of the allshare dongle, does it look like image 1 as i posted?
I recall you mentioned the dongle's hdmi signal is what triggers the docks micro usb port for kb/mouse control and charging, so for clarity i drew the wiring method up.
The next two wiring diagrams are what I'd expect to do as i finalize what the connection should/could look like...
I'm always in for feedback on streamlining the connections - the simple yet two part method will be just having the official smart dock, assuming it works with the s3, powered with one usb port, hdmi to hdmi mini and usb micro to the usb port, though maybe modify the output to delete charging power from the kb/m micro usb port...

Sorry, don't have much time and will have a look at your drawings later... The presence(!) of a device connected to the HDMI is detected by checking for a "Ground"-connection of one of the HDMI-pins (from googling I remember it to be HDMI-DDC/CEC) - that's what powers up the Lapdock (and activates the USB-Ports). No need for an already powered device on that HDMI port. The problem is however that there are many HDMI adapters/extension cables out there which do not pass that specific wire/connection and then the Lapdock will not react when using those. There is however no need to buy these overexpensive Motorola cable sets (those prices are unbelievable!)... my adapters & cables cost in total about 9 Euros.
+5V on the OTG-USB cable from the peripheral device (=Lapdock) to the host is not "liked" by most hosts (the S3 did not really react on it but it is probably not a good idea anyhow) so I cut the 5V red wire of the micro-USB(female)-to-micro-USB(male)-cable. On the latter you need something to signal the S3 the OTG mode (pin 4 grounded to 5). I do that quite stupidly using additional USB->OTG-adapters but you would have to take care of that in your MHL/OTC combi adapter with resistors etc. anyhow.
The "chinese" Adapter is vertically squeezed. The S3 goes into the correct HDMI-out mode including the (stock) homescreen to be usable in landscape mode - that is not a problem. Probably the 1080p30Hz mode is not well understood by the Lapdock and/or the adapter does not correctly "negotiate" the right resolution-/display ratio with the display or the quality of the sync signal from the adapter is really bad. That chinese adapter is not too bad for Full-HD TV sets but unusable for anything else. I did not try the official one. The Lapdock works however well with the dongle.
This info is much appreciated. I took the dive and ordered a lapdock from bensoutlet.com for $50 to play with. The regular one is $60 - but the keyboard that adds Hebrew letters was $10 cheaper. I figure the lettering doesn't hurt anything so I'd rather save the $10.
If anybody figures out how to simplify the connections, or perhaps someday enable MHL out + USB host with this thing - please post back.
Right now - I spent an additional $6 on dealextreme.com to get a microHDMI (female) to HDMI male adapter, and a micro usb female to male adapter so I can try to use the keyboard.
The result is going to be pretty cluttered, but I figure $50 is cheap for a portable, self powered HDMI monitor that could also power stuff from it's ports.

Your drawing No 1 is what I use (see below). No 2 is how it should be indeed (but where is the "modded cable" coming from?). While No 3 will not help you since only the presence of a shortened HDMI-CEC pin (+ opening the display a bit) will power ALL the USB-ports including U1+U2 (that activity mode of the Lapdock is indicated by a small white LED next to the touchpad) - so there is no "pre-power" available. But (again) anything that provides that ground contact on the HDMI-plug will do the trick... I actually have one 90degree HDMI-adapter (don't know how to call it in English), which does exactly that and shortens those pin(s) and simulates to the Lapdock the presence of a device (I assume that is NOT on purpose but it works with a second, identical adapter as well). Don't take me wrong you do not need that one if you conect a device (any) directly to the microHDMI-to-HDMI adapter but it is needed when you use HDMI extension cables (etc.) that do not pass all wires to the HDMI device.
I attached some pics how I wire that thing. Pic 1: the micro HDMI plug on the Lapdock is turned by me by 180deg just to make a bit more room for the microHDMI(fem)toHDMI(male)-adapter. You may directly attach the dongle to it (it is relatively stable and easy to carry around - pic 2). That's what one could call "entertainment mode" since you may want to watch videos etc. this way. But than you have not enough space for the microUSB-cable for kb/mouse. That is what I use the 90deg-adapter for. This adapter alone signals already the Lapdock to power up (no other HDMI-cable or adapter I own does this). Back to pic 1: The microUSB(fem)-to-microUSB(male)-cable has the red 5V wire cut. The microUSB-to-USB + USB-microUSB-OTG(!) adapter is there only to signal the OTG-host mode for the S3. The stuff on the right are things you may use on the free USB-port.
That strange device with the mobile speaker attached to its headphone jack has to be explained: it is a (5 Euro) "USB sound card". That is a bit odd... the Lapdock has stereo speakers which are working well (but not great) and the audio-output via HDMI(cast) to the Lapdock works perfectly (sound is ok and in sync when watching videos & you can control volume etc. from the S3 or the Lapdock keyboard) but the allshare cast SW on the S3 does not allow you to plug in a headphone or connect a bluetooth audio-device to the S3 for output of the video(!)-sound. You can use headphones for mp3-player music while using an HDMI display etc. but when you switch on a video you have to remove headphones otherwise the allshare connection stops. There might be two reasons 1: HDCP, 2: there is a small lag in video display from the wireless transfer protocol and the audio stream is equally lagged on purpose to be well in sync with the video stream. You may want to bypass that artificial restriction because the Lapdock has NO headphone jack ... and you can by using such a "soundcard" which is fully supported by the S3 but the sound is then indeed a bit "in advance" of the video stream.
Less exotic devices you can attach are external disks/pen drives or even game controllers (all of them work)... Pic 3 shows you how I wire it for "productivity mode"

Thank you. 50$ ! When they are as cheap go and get some (or better get many)! The Lapdock is really, really useful and works with many devices.
I originally bought it for the Raspberry Pi but I use it as well with an Archos A80G9 android tablet (not so often since the tablet is big enough anyhow) which has seperated (mini)HDMI and USB-OTG connectors (as it should have been done for all mobile devices including the S3) and used it for my "old" Nokia N8 (miniHDMI as well). In that case USB-OTG does not work since the N8 does not support USB hubs but you can chrge it and watch movies on the Lapdock display with it (in the train ...). The RasPi is powered via the same cable that is used for kb/mouse. In that cable I did obviously not cut the 5V wire. The power the Lapdock provides this way is sufficient to operate the RasPi (+ wifi dongle) ... about 1A is needed for that. So it should be possible to use that power via that OTG microUSB port for the S3 as well ...
What abot the EDD-S20E dock won´t that work with the lapdock ???
Problem is the dock is useless for my next device in 2 - 3 Years....
The allshare cast dongle might stay usefull even with the next gen of android phones....

Anyone know where one can be brought? also why have I read stuff about the s2 having mini usb? it doesn't it has the same propriety connector as the galaxy s.
It's MHL. It's the supposed new 'standard' for connectivity. I think most devices are using that connection nowadays. Last I heard was Clove saying the MHL adapters won't be out until June.

I can't find any evidence that it did.
http://en.wikipedia.org/wiki/Mobile_High-definition_Link
It's the new standard, but that doesn't mean older devices support it. The SGS2 is one of the first AFAIK
But nothing on the market will currently work? HDMI out from a mobile is just supercool!
I have both an sgs1 and sgs 2, my charger fits the micro usb (the only i/o connector) on the phones, perfectly
The connectors should be the same on the S1 and S2, but only the S2 is MHL compatible.
I think MHL can use any 5 pin connector to send an HDMI signal while receiving power for charging.
I'm not sure if you'll be able to use the MHL HDMI out and USB at the same time, but I hope this is possible.
I'm also guessing that the adaptor will need to be a clever one with circuitry rather than a passive adaptor. Does anyone know if this will definitely be the case, and if so I'd imagine it'll have cost implications! Hope I'm wrong and a passive adaptor is possible
Coming from a LG Optimus 2x, that came with a Micro USB ---> HDMI cable. These are available from Ebay for a GBP 10 - would these work?
Yea guessing its just MHL compatible as the old port was usb compatible. Thats annoying, with all the talk of this new standard usb-hdmi port I was assuming it would use a standard connector and not a proprietary one.
It stupid really if all manufacturers used the same connector we wouldn't have to have multiple chargers/docks/cables
You can't use the USB port for MHL and USB functions at the same time, this is confirmed (if you search for MHL at youTube there is a great video with a person from the MHL consortium explaining it).
To badasschris: this isn't a proprietary port. Samsung, Nokia, Sony, HTC, Toshiba, and quite a few other partners are involved with it, it seems likely to become the standard for mobile devices (iPhone aside, I am sure Apply will continue to push their proprietary ports).

Are you absolutely sure it isnt proprietary? Why I am getting confused is because it has the same port as the galaxy s1 and I heard nothing about that being a standard port and you always have to buy a samsung charger not a [standard port] charger e.g. mini usb charger for any devices which have mini usb. So you are saying at some point the other manufactorers will have the same port and I will be able to use my galaxy s charger to charge them?
Galaxy S is a standard micro USB port, and lacks the MHL connection, its not proprietary at all, I use several non-Samsung cables to charge the phone in my car and from PCs. Most manufacturers, Apple excluded, use micro USB charging now.
The port in the Galaxy SII is not the same as the Galaxy S, as it has MHL connectivity in addition, but its function as a micro USB port for mass memory and charging is perfectly standard, and doesn't require special cables or connectors of any kind.

lol I had to thank you there I've been a right plonker. I remember seeing someone say the origional galaxy s was micro usb and then when I saw it I thought that't not micro usb. It just clicked I have been getting micro and mini usb confused. When anyone said micro I immediately assumed mini
Glad I got that sorted.
Is it possible to buy an MHL to HDMI cable? Where?

That sucks. I was hoping to look into making a tablet dock that used a USB capacitive touch screen & HDMI output for the screen.
A laptop dock using Bluetooth for the keyboard and HDMI for the screen would still be possible, or a tablet that used Bluetooth for the touch-screen.
This phone is powerful - it's annoying not to be able to use the hardware for more than just a phone.
I reckon Motorola is thinking along the right lines with the Atrix, and I hoped other manufacturers would be too, but this combined port indicates Samsung are probably not.

I reckon Motorola is thinking along the right lines with the Atrix, and I hoped other manufacturers would be too, but this combined port indicates Samsung are probably not.

Plus you have the added fact that samsung like to mess with bluetooth meaning many devices wont work with it. I really hope the bluetooth situation gets fixed somehow as this device paired with a screen and a bluetooth keyboard/mouse and game pad gives you a portable computer / games console. without it its just an amazing phone
This should work perfectly with bluetooth mouse and keyboard, my SGSI does. It should also work with a Zeemote, unfortunately it doesn't have enough buttons to be that good for using in emulators.
I can confirm that the igo stowaway bluetooth keyboard works fine w/the SGS2 in case anyone's curious

Good question. That's what we are all looking for.
So far i have only seen two places selling them Clove and Expansys are doing it 2 £24.99 they ar egetting them in on the 28th May
Anyone know if it's possible to use MHL in conjunction with a microUSB to USB host adaptor to output to HDMI and access an external USB drive at the same time? That'd make the SGS2 an amazing portable media unit.
No, it is not posible. Its an either/or connection to the micro USB port.
Shame, because as you say that would really be a great thing. MHL consortium are considering a number of improvements to the 2.0 MHL spec, so in future devices this may be a possibility.
So MHL can't be used when I'll plug a USB-Hub?
No, sadly not.
It's a shame - for now I'd prefer micro USB & separate HDMI port so USB can be utilised as well as an external display.
As would I, and a lot of others I suspect.
But you've got 16 GB memory and can copy your stuff to the memory and watch it later via MHL on your Flat? So this is not a big problem, I think

I would use allshare to stream the movie or whatever to your phone from a laptop and connect the phone to TV via the MHL HDMI adapter...that way you have access to ur laptop's data without being hardwired to it

Not that I'm aware of...
I bought one from Ebay and can't really do anything good with it. Display shows briefly for 3-4 seconds on TV then disappears again. Don't know why.....I hope it's not the device itself because I tested 2 phones, they were bought at the same time, but none of them would work correctly....
If by generic you mean a not samsung one or one not dedicated to the SGS2 then i actually use a one, from ebay or someting like that, everything works perfect you just cant forget to plug power to it, and about the not working one, it seems mine gets jammed by gsm signal (i.e. when receiving a call), so from time to time the image disappears in a blink of noise, maybe that is your problem too, try it in airplane mode.
Oh, I think I misread that question - I have actually used a generic one with my SGSII (a prototype from the MHL consortium) and it worked fine!

Uhm no. I've been streaming with WIFI through MHL no problem for MONTHS. Using the Original Samsung MHL connector of course.
I have to put mine in offline mode to be able to use the MHL adapter.....
As for USB-OTG no luck yet.....
On Amazon, Ebay, DealExtrem ... you will find adapters that can do 3 things at a time:
- output HDMI
- let phone work as usb host, so that you can plug kbd, mouse, and external HDD (second wifi card, wired ethernet ...); once you have the usb A plug, just pub a hub
- recharge the phone (what is not possible with the legacy short OTG cable).
+ read memory cards
Such devices are sold as MHL devices. Some MHL devices don't to all that.
Take care. MHLv2 is more complex than MHLv1.

Could you post a link as an example for such a device, that works properly (if you've tested, or you know it works) ?
Thank you
I can post links, but ... I have not tested any of those. And don't know any one personally who tested it.

Monobloc:
http://www.ebay.fr/itm/Micro-USB-Ho..._MobilePhoneDataCables_JN&hash=item258600844e
I don't like the monobloc version; I fear it's too heavy, and may help breaking the phone plug.
There are all sorts of OTG and MHL cables. I have seen OTG dongles as short as 4cm (monobloc), with small cable (8cm: 4-8€), with long cable (1.5m .... should be 7 feet), pure HDMI (passive cable, no card reader, 8-12€), VGA (including very cheap HDMI to VGA converter, 20-30€ ... including sound output). In some case, you need to buy accessories (extra power supply, extra uUSB cable, extra HDMI cable). Also seen a very cute hybrid card reader: http://dx.com/p/285865 (I love this product design, and I love this URL syntax )
Don't forget that there can be mistakes in item description.
Here I have described how to build an external battery:
http://forum.xda-developers.com/showpost.php?p=54036759&postcount=17
On previous phone, I just soldered additional battery to internal one; on my new phone, I will do something more complex, and more flexible.
Loosing power via OTG/MHL is not a fatality. Most phone have an other hidden power input:
généric, that uses the USB plug:
http://www.dx.com/p/reverse-qi-wire...arger-receiver-for-micro-usb-cellphone-312805
TRIPLE CHECK POLARITY; I took the wrong one; have to fold the cable.
So ... even if your OTG/MHL module takes power from your USB, and can not recharge your phone, the specific shell can charge your phone the other way So, you need to build an internal specific module:
https://www.youtube.com/watch?v=UK7PRJ4SiK0
S2 specific back shell, so called receiver:
http://www.aliexpress.com/item/2013-newest-wireless-charger-for-samsung-galaxy-s2/1266101036.html
http://www.exportprive.com/en/batte...reless-charger-set-for-samsung-galaxy-s2.html
http://www.alibaba.com/product-detail/QI-Wireless-Charger-for-Samsung-Galaxy_821969998.html?s=p
The SGS2 is not designed to accept wireless chargers, so, you have two options:
- solder and take the pins out (cf youtube) (do not solder coild to battery, or you could overcharge the batt, and burn your phone ... I mean, physically set fire)
- find an item that includes back shell + specific battery (exportprive)
Many recent phones have the internal connectors, so you just need to change the back-cover. In this case, the software will be able to know the charger is wireless (as opposed to AC, and USB; advanced battery tools will show those 3 possibilities). I believe the motherboard for my HTC One M8 is designed to have those pins, but I can't find the specific cover yet (maybe in a few months); only found it for M7.
Given that the I9100 allows keyboard, mouse and hdmi output, it would be great to rig it up to perform as a little netbook. So, one would require
a battery-powered LCD with HDMI input,
a seperate power supply (battery with micro USB output) for the HDMI adaptor (seems like that is necessary)
bluetooth keyboard and mouse/trackball/touchpad (since it seems you can't connect both USB and HDMI at the same time),
and possibly a ROM that would take advantage of such a setup.
[EDIT: scouring amazon reveals portable LCDs with HDMI input and many external phone chargers.]
So my question is, what is the feasibility of such a setup, given the necessary hardware? does the necessary hardware exist? has anyone done such a thing already (quick search on google revealed nothing)?
I don't think it would be feasible to do it. You'd need an MHL adapter which people say drains battery even when it's plugged into a socket, and an OTG cable and afaik you can't use both at once. Bluetooth mouse/keyboards would further reduce the battery life.
Not to mention with all of this you'd need a fan of some sort to keep everything cool.
Just buy an ipad or one of the countless droid pads and a nice bluetooth keyboard.. you probably don't want to carry a screen larger than 10 inch with you.

After playing MAME on my tv with the MHL cable for an hour and using a PS3 sixaxis controller over bluetooth, I loose about 15% battery life. Yes its plugged in otherwise it wont work The back got fairly warm after the first 5 mins.
Part of the problem with battery drain when using MHL is the inability to turn the GS2 screen off which is a pain. I was watching a movie on the TV and it was distracting to have the screen mirroring the TV.
If you want a netbook type thing then just get an original Galaxy Tab and a BT keyboard case like this one
This is what I use with my Tab and it works fine.
You could buy a Motorola Atrix ;-))
I have been trying to use some flash drives as external storage however I ran into some trouble.
1. First of all without rooting and getting a kernel or something (which I cannot do as my phone is sim and bootloader locked to o2 right now) it can only read FAT32 formatted drives rather than NTFS.
This means I have to either split >4gb files into two smaller pieces or re-encode. I don't like re-encoding because of the great hdmi output so why not carry full blu-ray rips
2. Does anybody know the power output of the USB port in the Xperia S? Is it something like 100ma or less? As you can see from my photos below here are my tests,
Sony 16gb Micro Vault Click USM-L (pink)...........works fine.
Sony 16gb Micro Vault Click USM-P (black)...........works fine.
Verbatim Stor N Go 32GB Micro USB (tiny one)..........USB Power Consumption Error
I don't like the fact that it is hit and miss when choosing drives and don't always want to carry around a powered USB hub or a Sony Ericsson Livedock instead of the tiny drives and the lightweight micro usb->female usb cable.
Its meant to be "USB On-the-go" not "USB can't go because my arms are tired and bag is full"
There is NO information on either Sony's nor Verbatim's website regarding the power consumption of their flash drives.
Any suggestion's?

hi i also bought a cheapy one from ebay and its perfectly fine
yes usb keyboard and mouse works fine, tried logitech k800 with unifying receiver and also tried microsoft keyboard and mouse desktop combo with big ass usb receiver. i have not tried bluetooth yet but that would be preferable to me because it will take one less port.
i would also like to hear about the livedock or if anyone has made a a simple y cable with "micro usb male" (to go into phone) split into "female usb" (for usb device) and "female microusb" (for charging input).
In fact why not go the whole kaboodle
A. Keyboard & Mouse & Headset & Phonejoy controller & Smartwatch : simultaneous Bluetooth
B. Flash Drive or USB Hub with multiple drives: Micro USB to USB adapter
C. TVOUT : HDMI
D. Charging : Female Micro USB input from same spliiter cable as B
now its a full desktop, NES, SNES, whatever all controlled by any of the above and the damn thing is the size of your hand
View attachment 962244
Basically does something like this exist?
This cable should in theory have the same functionality of the bulky livedock?
I was thinkink about same thing: y cable, so we were able to access flash drive (memory card) along with charging the phone. But i think it is not possible with JUST a cable. I think it is possible with live dock, but live dock probably got some sort of electronic curcuit board which controls flash drive and charging at the same time. Unless you would buy live dock for other phone (P in example), take curcuit board out and do DIY.

That all sounds really cool to experiment with, but thats alot of gear to cart around... wouldn't it be easier just to buy say a PSP(homebrew) or perhaps a PSvita? Emulation is wasted on a touch screen.
The kernel mods in the dev section have already enabled ntfs fs reading amongst other things, you could flash these right now or the first roms will probably have this soon which should help you out quite a bit.
I bought the livedock for the XPS hoping it would work for usb charging via computer, it does not; a Y cable is a good idea tho... unfortunately the dock just does not suit the XPS at all, does not sit correctly, u have to lean the dock usb connector on the ground for the whole setup to be "somewhat" stable and just looks silly, not to mention unsafe.
Those clove youtube vids area bit of a con imo.

Does anybody know where we can buy the original Sony Ericsson USB OTG? Also, does anyone know the part number? I do not want to use any other brands. Hope someone could help
Any reason why? You can buy it of ebay for just a couple of pounds and is working fine.
I connected Logitech RumblePad to my xperia S (Using some samsung USB adapter)- including vibrations, so i think power output is pretty ok.

hi it wouldn't be too much to carry around, consider having a phone and a vita and a laptop? at what cost. you'll still always need at least 2 devices, you phone and another. now you can have all three from one nice looking device and can take each accessory when required. ie all three to a hotel, just the keyboard for working on, just the gamepad when you feel like it. check out the freedom pro keyboard (better than a laptop's) or the phonejoy for a full vita beating experience (comfort wise - wireless on big screen anywhere)
and minimising what we need to carry is the whole point of finding if such a y cable works because then we don't have the added bulk of the Livedock...
thanks for your review of the livedock, even more reason to want that cable! I cant believe there is no grip, i wouldn't have been able to assume that from the Clove videos. its a bit silly that the Xperia P has the new smartdock but because they put our ports on opposite sides we can't use it
i noticed the devs have a kernel for ntfs compatibility but i cant use it as i havent even received my sim unlock code from my network let alone finding out if my locked bootloader can be unlocked after this. plus ive just discovered how bad the yellow tint issue is on my phone, so its a bit of a wait for me!

yeah but i don't think the wireless receiver for the rumblepad takes up as much power as constant reading from and powering a flash drive would. the wireless receiver doesn't need much compared to that and the controller itself has its own battery

I know the right angled ones will be better, but i just love the build quilty of the Nokia one so will probably give it a try.
To anyone interested in OTG cables:
Guys, the Nokia OTG cable works just fine and is VERY good quality and very common anywhere (quite cheap as well).
Tested by me. Already connected my 16GB Ultra Speed Transcend USB drive and works fine.
I've been using OTG since day 1 when i got the unit - like the OP says, the power consumption of the USB port for devices are hit-and-miss.
Some usb drives works great, some consumes too much power and cannot be powered on; so far, my wireless keyboard+touchpad set (rapoo) works great.
Hi, I don't personally own a atrix, but I have ordered a lap dock in the hopes of making a laptop with the Odroid U2 board. However, the U2 requires 5v 2A to power it. I was wondering how I could draw 2A from the lapdock.

I own an imito MX2 tv stick and it also needs 5V-2A power supply. And i get that from lapdocks USB port only issue i had was with the cheapo USB cable that came with device... i used one of the better once i already had and it works no problem
So I guess it should be hassle free for you too... just make sure you use a good cable
Any updates on this? I have an atrix dock i bought for modding but haven't touched yet. This u2 looks amazing.
On a side note it makes you question the price and size of desktops. For $180 imagine 2 of these were combined, 8core, 4gb ram....

Really glad someone replied to this thread.
First off, I did some digging around the hardkernel forums and found out that you could indeed power the U2 off the lapdock micro-usb just fine.
Second, in reply to 96shox, the new Samsung S4 is rumoured to have a eight-core processor and I believe the future generations of the U2/X2 will use something like that and probably with 4gb RAM. So it may be a good idea to wait a while if you can

Lapdock Help needed
Got Lapdock for 70~ dollars from ebay 2 weeks back. After reading so many blogs and viewing youtube videos, I thought my Raspberry Pi model B could be put for good use along with some of the awesome hacks I found on this site. BTW i also have a nexus one and recently a nexus 4. So naturally all this holds a place in the Lapdock realm of things to be connected to. My question is I have got the following wires after a lot of thought, could some one here tell me if this will work:
1. Raspberry Pi Model B
2. Lapdock Atrix 4G
3. Micro HDMI female -> HDMI Female Coupler as found here cgi <dot> ebay <dot> com/ws/eBayISAPI.dll?ViewItem&item=140943218129
4.Micro USB female to Micro USB Male Charger cable from Ebay
5. HDMI Male to Male coupler.
6. HDMI Male to Male extension Cable 3 feet
Idea is
1. Using Raspberry pi Connect #3 item above and #4 item to Lapdock. Then #5 sits on #3 and to #5 I connect the Rasp Pi. For power and control #4 to RaspPi. Will this work?
2. Laptop second monitor. Using #3 and #6 connect HDMI Male to Laptop and use.
3. Using Nexus 4: Need to buy either a Miracast receiver or a Slimport and hope it works. (Do I need to root the phone, if yes what is the ROM preferred?)
4. Using Nexus One: Not yet figured a way but as of now will not work.
5. For PS3 : Same way using #3 and #6.
I got the wires and plugs today. Sadly the #1 above does not work
I plugged in the Micro HDMI female -> HDMI Female Coupler to lapdock and then HDMI Male to Male extension Cable 3 feet to Raspberry Pi and powered Rasp PI with all possible means (Power from mains as well). Sadly when I opened up the lapdock nothing really happened. Blank Screen!!! I even ensured that the Lapdock is fully charged. If I press that little button below the opening slot it shows 5 tiny white LED's . But does this not have any kind of Power ON button. I opened the screen and try to use the USB at the back as a power source for my Raspberry Pi, sadly that too did not power ON.
Is the Lapdock DOA?? Better not be as I got in Ebay and dont know how to deal with it OR is Part #3 the culprit.
Any way to check if the Lapdock is dead with what I have before I order another round of wires. FML, all the enthusiasm went down with this.
Help please.

My Odroid U2 + Lapdock
Hi,
I know this is a late reply...
I just got my odroid U2 + lapdock project working last night so I figured I'd share the result. I used the bionic lapdock btw.
I'ts completely mobile. I was able to power the odroid off of one of the lapdock USB ports. The other USB port has a 4 port hub attached that contains the wifi and bluetooth adapter. The micro usb is connected the one of the USB ports on the odroid and has the power wire disconnected. It works in connecting all USB ports and the keyboard/mouse pad from the lapdock. The HDMI works for both the video and audio and is running at 720p.
I installed linaro 12.11 and all updates, including mali drivers, onto the odroid U2.
The only disadvantage is that the lapdock USB ports only supply power when the screen is opened so if you close the screen the power to the board is cut. Besides that it's running flawlessly!
Also, I used an old Nintendo 64 power supply for the "case", the odroid fan is mounted on top. I don't recommend it because it took a lot of modding to make it work. I removed the heat sink that comes with the odroid and put small copper heat sinks onto the chips which works great and doesn't overheat.
So I'm attaching the pics, most important part lol. By the way it's ugly.

Yes it runs in 1366x768. The lapdock is 720p but thats it. I'm pretty sure it won't run in a higher resolution image.

Any updates on this? I have an atrix dock i bought for modding but haven't touched yet. This u2 looks amazing.
On a side note it makes you question the price and size of desktops. For $180 imagine 2 of these were combined, 8core, 4gb ram....

Exactly what was on my mind. Though I am expecting newer versions of U2 by the end of 2013 or start 2014, which would sport new exynos 5. Lets hope for the best.
