I hope this works generically on all Android 3.1+ Tablets rather than a limited subset of supported Tablets. If it works with the Tab 10.1 then creating a docking station at home would be so straight forward. Keyboard and mouse connected via Bluetooth and then connected to monitor via HDMI cable. It would avoid the need of Samsung's desktop dock accessory which will probably be quite expensive.
I'm pretty sure I can do 95% of things at home on the Android tablet while the other 5% I can get away with remoting into a headless Windows PC from the Android tablet.
Interesting. Thanks for the link.
Reaching for the tablet screen to manipulate has always seemed a weakness of the wireless/bluetooth tablet keyboards. Maybe a keyboard with embedded touchpadcould remove the need for a separate device (mouse).

It would definitely work on the 10.1
You may even try other brands of mice, the 3.1 software should be compatible, but it will be hit or miss.
So far, Samsung desktop dock accessory looks better than the others in my opinion, but it's not rechargeable so you can't bring it with you on a trip and that's a big negative.
Why would the desktop dock accessory need to be rechargeable? I would have assumed that any power it needs will be drawn from the Tab or from mains if it is connected to power (which would also charge the Tab at the same time). I really hope that the desktop dock provides USB ports for keyboard and mouse as well as HDMI connection to a monitor and thus it gives full docking functionality.
With regards to Logitech's bluetooth mouse, I didn't know standard Bluetooth supported mice. The fact that they do probably means we'll see cheaper devices coming out and possibly a Bluetooth dongle/device that will allow cheap USB keyboards/mice to be plugged in instead.
Time will tell I'm sure.

Well, if it would be rechargeable it would just be a nice plus - to use it on planes or somewhere where you don't have a plug.
It looks like this model doesn't have a USB connection - probably the same port that's on the galaxy tab itself.
I also saw another keyboard on a video that's more of a folded case, hope that one is portable.
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 ;-))
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!

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....
Hi folks,
As I understand it, the Glide supports both HDMI out and USB On the Go. What I'd like to do is set up my phone to be a basic laptop.
The first part of my plan is to get the right cables. Does anyone know of a combo cable that provides both HDMI female and USB A female to the phone so I can hook one end up to a powered hub with an ethernet dongle and keyboard/mouse thing, and at the same time hook up an external display? Also, if I do this, I assume the hub will need to provide power in some way back to the phone. Is that correct?
Or is this going to be so expensive I should just use a cheap computer?
Thanks.

As I understand it, the Glide supports both HDMI out and USB On the Go. What I'd like to do is set up my phone to be a basic laptop.
The first part of my plan is to get the right cables. Does anyone know of a combo cable that provides both HDMI female and USB A female to the phone so I can hook one end up to a powered hub with an ethernet dongle and keyboard/mouse thing, and at the same time hook up an external display? Also, if I do this, I assume the hub will need to provide power in some way back to the phone. Is that correct?
Or is this going to be so expensive I should just use a cheap computer?

Assuming a computer on site, you could always vnc.
From past experience with other PDA's, you will -quickly- grow tired of this and end up purchasing a laptop anyways.
Not that you'd want to be internet'ting, much, on a TV, either. For anything short of a quick search, weather, TV guide, you're going to want to cross the room to your laptop, IMO.
Which is probably what you'd have your HDMI connected up to, anyways. Although using the Glide as a remote in that situation is probably attractive. Or as an XBMC control sort of thing, but, again, likely the content would come off the computer rather than the glide, the glide just remotely controlling it.
You can easily test how you find this, either by using a bluetooth keyboard and playing (never mind the external screen for the moment), or by vnc'ing to it from a computer (pretend it's a bluetooth keyboard and it's an external monitor, for the moment).
Technically possible, not practically feasible.
Chromebook?
Just get cheap laptop. It will serve you better and will be much easier to use

HDMI out is supported by the SoC, but to the best of our knowledge those pins aren't actually connected to anything in our phones. That said, there's a protocol for outputting to an HDMI device via a USB dongle that doesn't require any hardware infrastructure beyond USB OtG, which we have.
In theory, you could get a powered USB hub (it MUST be powered, no way in hell the phone can put out enough current to support all this), plug a keyboard and mouse into it along with one of those USB-to-HDMI dongles, then hook the phone up to it as a host using an OtG cable. At that point it's just a matter of ROM/kernel support of all the peripheral hardware. (Ask dman? Nah, I'm sure he's WAY too busy.)
If you are just using it for media as like an htpc, I'd reccomend skipping all the usbotg stuff and just connecting a net book or some other cheap PC to your display.
My current setup: old netbook with 1tb external hooked into TV, controlled by the glide (unified remote app) and the external drive is also network shared so my glide (and tablet) can read from it.
Its served me well for playing all of my local video files as well as flash video and light browsing. Depends what you're using it for though, I suppose.
The only time I've ever really used HDMI out with android is to play n64 emulators (or other games that support a bt controller) or if my girlfriend is watching desperate housewives or something on the main setup. It works well enough for that, but not enough that I would make a habit of it.
Hey guys, I had an i dea on a case, first off im unsure if itll work, but want some feedback of what you think. First, i wanna basically make if a mini laptop type of thing..but still maintain the tablet as it is. The case will charge, have a keyboard, usb ports, and internal storage. I am going to attempt to make the usb box with the storage removable, on the bottom of the case. It would be nice if the keyboard were removable too but thats un important at the moment. For charging im going to utilize the qi(?) wireless charging, build this into the case. In order to power this i will remove the port off of the system and place a deans connector at the base of the case(all connections will use deans connectors cause they are easy and modular) the location will depend on the case, but they will either be at the back along the very bottom edge or on the bottom. The otg adapter will be built into the case so when you slide the nexus in to the case it connects to it. This will also run down to 2 deans connectors. These are how the usb hub will become removable. The usb module will house the port for the power adapter, an un-powered usb hub, an internal memory of some sort, and if the charger is plugged in there will be a switch to change the un-powered usb hub unto a powered one. (will not be using stock qi power adapter, will use something slightly more powerful in order to split the power between the qi and the usb hub. I will be building a circuit for that) All the connections will connect to a corresponding deans plug. Thus making it easily removable and turning it back into a regular case again. Add the wireless keyboard that fits the case, and a wireless mouse and possibly the tablet running full ubuntu(have a few ideas to fix some issues with it for instance the kubuntu desktop over the normal ubuntu desktop to assist in some lag). All of it will be encased in black leather( hopefully i can find the same texture as the manufactures case, if not i may completely strip the case and use only the hard parts(for instance the frame holding the nexus) and create my own case( may actually be my best route).
Also streaming out to tv will be covered via miracast.
So what do you think? Possible? Will it work? Worth while?
What case and keyboard would you suggest? Preferably something cheaper..

Does no one think this is a good idea?

Sounds like a good idea in theory, but if you want a laptop why dont you just buy a netbook
As the person above me said, it's a good idea in theory, but what is the impetus for designing or using this? Not being snarky, just curious what purposes you have in mind for this product or for what situations it could be beneficial. What would be a marketing strategy or hook to interest people that separates it from a laptop or netbook?
