Wonder how securely it will hold the phone? If it's solid it would make a good car holder by sticking it to the dash and just clipping the phone in when needed.
Here too: http://www.expansys.com/product.asp?code=126238&asource=119353
Expansys USA just shipped a couple of these to me. I should have it tomorrow (Tue)
Ditto.
this looks nice, but wish it showed more pictures. It is only 18.95 on expansys-usa. Please let us know how you like it!
A pretty simple cradle. It has a single USB port jack that accepts either a USB connection (which also charges the Universal) or the AC/DC jack. But doesn't replicate any of the other ports (for example, the headphone jack is covered up when in the cradle). It also has a notch to allow you to access the stylus if it is still in the unit while cradled. But it is still difficult to pull out. There is also a hole to balance your stylus in when not in use.
It has a single blue light on the front whose sole purpose appears to be to tell you if the cradle is plugged in. This light is on all the time and doesn't change (so far). The lights on the Universal itself still determine charge status.
The Universal lays flat in the cradle. However, you have to be careful when pushing it in. The height of the USB port on the Universal and the recepticle in the cradle are off by about half a millimeter. You kind of have to look at it and maneuver it while guiding the USB pieces together. You can't really just lay the cradle in and push.
It costs $19 US and, well, is worth about that. Useful to keep your Universal from flopping around your desk while connected (which, to be fair, is pretty useful considering how much the Universal costs), but not much more than that. Nothing fancy.
Mine arrived today. Deeper than I thought. fixed with 2 double sided tabs.
Any ideas how to hide the cable? It's a company car and I don't want to hack it about.
Is it really ok to drive about with the flip cover open? I suspect long term bumps from the road may damage it prematurely. Any thoughts?

I like it but it does need some sort of "spring" to absorb the bumbs. Looking at it, a piece of (stainless) steel bent like a "U" would help give it some spring - depending on the gauge, that is.
Ive been plagued by the thought that the damn dock should...by all accounts have a USB out. Now I suppose that it may have came down to a decision point of "Which is the more likely scenario... audio out or USB to a computer out", but I find myself squarely in the "dont care about audio" side of that debate.
The idea would be to crack this little sucker open, see whats inside and (hopefully) take the micro-usb connection that it has out the back of the dock with a new tip.
Now that Ive opened it up, I believe I can get there. I'll tinker around with it in the next few days to verify things like theres no "control" (or similar) signal running through the USB connections from a power perspective and whatnot. If I can do it, it will be my intent to make it look as stock as I can and I'll be sure to post any walkthroughs, pics, etc that somebody else might want.
To open it up, you have to remove the rubber pad from the bottom. Its got a lot of adhesive on it and (at least in my case) looks like something that I can successfully stick back on.
Under that, you'll find what appears to be depressions in the plastic bottom. Take a utility knife (or similar) and cut around the edges of the depressions. They are part of a plastic film that I saw absolutely no reason to be afraid of removing.
Once the holes are exposed, you'll need a T4 bit to remove the screws. Then you can just open it up.
Thats the extent of my exploration so far...
Heres a pic:

Would you mind checking which of the connectors for charging is (+) and which is (-)? If I am really trying to build that alternative charger connector then I'll need to know. Thanks man!

This will come in handy when the time is right! :thumb up:
as far as i can tell all you would need to do is make sure there is enuff room and put a male to female cable inside. No need to mess with the board inside.
I think you've got a great idea. Any Progress yet.
Thanks for posting this picture. I'm going to do a straightforward mod by simply drilling a hole out the backside of the dock, running the wire through the hole and soldering the leads together. This method keeps me from having to dremel an exact fit USB-A connection and providing an internal support for the port.
Oooooh yeah, mine will be ghetto rigged tonight. I'll order a female mini USB socket from digikey or somewhere to make it a little better in the future - but for tonight its getting hacked together.
Thanks for the pic, it was just enough encouragement to take it apart.
I'm tempted to buy the cradle, is there any way you can take a picture of the front and back of the PCB, I'm curious if there are existing pads for the USB cable.
I'm also curious about the possibility of adding a micro HDMI connection to the standard dock to make a "Swiss Army" dock, those pictures would help be get a better idea if I should buy this dock or the HDMI dock.
I don't understand why Moto didn't make a dock with power, HDMI, USB, and headphone. Then you can keep everything hooked to the dock and add/remove the device as desired. This is how most PC docks work. Is there a technical issue that would preclude all ports being brought out from the bottom connections (understanding the devices headphone jack is on the top)??
A design issue I see as far as wear and tear is the lack of docking "keys" built into the bottom of the device to aid in port alignment. It seems like getting the right alignment will be hit and miss and could put undo stress on the ports.
You were using a nail clipper to open it?
If I spend the cash for a moto brand dock, I am going to add a fullsize USB/HDMI and power to it. There is no excuse for not including these.

Hi, I'm bumping this thread to ask if there's any chip or so in the dock to control the audio? I would lika to make a microUSB to 3.5mm cable to avoid the distrubances from the wifi in the badly insulated headphone-port.
I imagine there must be since usb is a digital signal and headphones use analog signals. Maybe I should go all the way and make a pocket amp instead
Thanks
Any clue what kind of device\dock the galaxy nexus will be able to connect to with those three metal connectors on the side of the phone?
a desktop dock was shown in the presentation last night.
eric b
Its mainly for charging isn't it?
Probably the dock have MicroUSB, Audio 3.5", and HDMI output.
hum with the all in one os I hope this means that docking your galaxy nexus to a tv makes it run like a google tv and that we can get a padphone-like accessory. One of the tings I love about android is there is virtually no reason for me to dock my phone to my computer, I can do 99% of the things I want over data, wifi or bluetooth (most of it without any need for me to interact with the device)... it would be a shame if they put those pins there just for that.

I hope there's Car dock as well as the Pogo desk dock - just like the Nexus One.
only problem is... that in the presentation it docked on the hand side of the phone. But the pogo connections are shown to be on the right hand side of the phone where the power button is.

What the hell is going on there? I'm figuring the dock at the time of launch was fictional and 3d generated and they overlooked this mistake.
As it stands having the pogo connection points on the right hand side is kind of dumb, as it orientates the device in landscape in the opposite direction to pretty much every single other landscape dock on the market.
Not only that if the phone does dock on the right hand side it will cover up the power button, which in most android phones is what powers up the touch screen. So they must have a solution there, I imagine it will just mean the screen will never turn off.
Really hope they sort this out properly, as this is why i have hung on to my N1 for so long, and I've been hang out for a next gen, 'wireless' charged phone.
SCOOP: the real galaxy DOCK
here it is people.
I am convinced this is it. Pogo pins and the notch out for the power button. Its exactly like in the Galaxy launch, but minus the dodgy 3D/photoshop render. It now docks on the right hand side, as expected from the placement of the pogo plugs.

I'd love to find this out too...maybe someone who has a dock and a voltmeter could fill us in?
I posted this earlier in the long thread about the official car dock with pogo pins that has still not been released but I don't want to derail the main topic of that thread so here is a new one, with a bit more detail added.
I have the steps that I actually took to do this listed below. I think there is probably room for improvement and many ways to accomplish the same end result depending on whatever strong skills you may have or what tools you happen to have. Not every step has a picture associated with it because either I couldn't hold a camera and do it at the same time or it just wasn't worth it to photograph a mundane task like tracing a line.
Also, keep in mind I was doing this for a GSM nexus. I can test whether an LTE nexus (both standard & extended battery) will charge in the dock sometime on Tuesday or Wednesday.
Tools & materials used are described throughout. After the steps/pictures I have some concluding thoughts including some lessons learned, things I would do differently, and some alternate ideas others might wish to consider.
DISCLAIMER: Bad photography ahead.
Step 1: Grab a good beer, somehow these things always take longer than you expect.

}
Step 2: Tape the phone & dock where you will be measuring with a caliper or holding it in a vise. I used masking tape which turned out to have the extra benefit of being able to see the contact points through it. Take a lot of measurements. You end up drilling the dock blindly so your results all start in how carefully you measure things. Don't use the numbers on my caliper for your own use... Somewhere around the time of these pictures I accidently zeroed the caliper so I don't know which ones are showing correct values or not. I only realized this because I measured everything again and realized something wasn't right with the numbers.
Step 3: Double check your measurements, make sure everything is square... I want to say the following picture is over board on my part... but it really is a fine line between making contact b/w the pins and the phone 100% of the time, 50% of the time, or hardly ever.
Step 4: I used a pencil to trace a line from the contacts up the side of the phone, and onto the front glass. I then place the phone in the dock and put a new piece of tape from the edge of the phone around the edge of the dock and traced the line back over the dock so that I had a good reference for where to drill in the side-to-side dimension. The vertical dimension was purely based off my measurement from the face of the phone down to the contact points. Because the glass is curved, take separate measurements for each pin.
Step 5: At this point I used a 1/16" drill bit to make two holes and then pushed the pogo pins through. Before proceeding I hooked up 5V power using aligator clips to the pins and put the phone in the dock just to make sure everything was in the right place before I really made anything permanent. In this picture the pins are only held in place by friction. The dock is very rubbery at this location which is nice for holding the pins in place. You can see how well you lined up the holes by placing the phone in the dock and looking through the holes. You absolutely want to see the entire gold contact nicely centered in there. If not, fix things now before proceeding.
Step 6: I then took a car charger and cut the micro USB end off. There really isn't much to picture here. I happened to use a car charger with a permanently attached cord so there were no data wires. If you use a USB cord that contains 4 wires, usually red, green, white, and black, just tape off the green and white (date + & data -), and use the red (+ 5V DC) and black (ground). The pogo pin closest to the power button is the ground and the pin closest to the bottom is for 5V (I confirmed this for both the LTE & GSM models). Middle pin, assuming the same paradigm used for the nexus one, is for signaling the type of dock and the bluetooth id of the dock.
Step 7: I soldered the 5V and GND wires to the pins as described, sealed some exposed conductor with heat shrink, and used an epoxy to permanently seal them in place. You want to make sure you use an epoxy that bonds plastic and I would also recommend one that advertises some level of flex/gel. If it's too rigid or poorly bonded to plastic you could end up cracking off on the very first insertion. Make absolutely sure that the pogo pin plunger is the only part of the pogo pin that is on the inside of the dock. Even a small portion of the rigid part will cause you problems when you push the phone in and it pops the pins back out or damages the epoxy.
So, did it work...
After waiting enough time for the epoxy to set I got what I had hoped for.
I also added an NFC tag to the inside that I'm using to turn on bluetooth, set car mode, etc, etc...
Here's a few extra pics:
It successfully charges my GSM nexus with both the standard and extended battery. It would appear to me that the dock holds the phone with the position of the front glass relative to the lip of the dock in a constant position. So I'm assuming my wife's LTE nexus will be able to charge on the dock as well (will test on Tuesday/Wednesday). That would be really good news for VZW people who aren't up to the modification but would like to buy the GSM dock if it ever comes to market. At this point at least, it can concluded that it's possible to make a dock that charges the GSM model with both the standard and extended battery with the pogo pins in a fixed position.
Now that it's been done once the thing that would make this an extremely fast and easy mod in my mind would be a drill guide jig. An L-shaped jig with drill guide holes that you simple place against a reference point on the dock and drill in the holes and never have to worry about all that measuring and how well you measure.
I also wish I hadn't soldered the pins to a fixed car charger. Now I'm tied to that thing unless I want to cut the cord and splice a new USB plug on the end. In hindsight I actually wish I had used a 2 conductor "boot" close to the pogo pins that would allow me change the cord easy and provide some level of emergency strain relief or break-free ability if the cord were to get yanked. On the topic of strain relief, this is why I recommend right angle leads off the pogo pins. It also might be a good idea to adhere the cord to a spot on the back of the part that holds the phone so that a snap tug on the cord pulls on that and not your pogo pin connection. It feels very durable and I don't expect any problems it's just something I would recommend.
As for the NFC tag, I would use the thin adhesive tags, you don't want anything thick enough to change the contact position. I used a 1K tag so that there was plenty of storage for long instructions/information that may be handy to write to it. Right now it just launches car home, maxes the media volume, starts bluetooth, turns off wifi, and sets a high brightness level.
Finally, I wish I had gone ahead and installed a middle pogo pin with a free hanging wire lead off of it. Just in case I felt up to going down that rabbit hole in the future. I wish I still had a nexus one dock around to see if the signal pin on those docks would communicate on the galaxy nexus middle pin. I know, different OEMs (HTC) but the code is Google's so I figure there's a 50/50 chance it actually would work.
Your move, Samsung.
Definitely going to try this. Where'd you get the pogo pins?
Also, the third pin ::should:: be shorted to ground to trigger car dock, if that's the purpose of it.
Keep in mind that the OEM GSM dock plays music through those 3 pins somehow, though it makes no sense to me whatsoever. Not enough pins.

The stock docks play the audio over bluetooth since it'll help alleviate any grounding issues/hiss that may occur. One of the reasons they cost so much.

Shorting to the ground is definitely not how the dock pin worked for the nexus one. Audio is also definitely not over the pin, its by Bluetooth. I've seen the code somewhere that insinuates the dock identifies whether it is a car or desk dock and its Bluetooth MAC. Shorting to ground isn't going to do anything.

Pogo pins were left over from some other project. Take a look at digikey or someplace like it. Might have to search for "spring contacts" or "pogo pins/contacts".. different vendors seem to use different terminology.
Hmm i don't understand the north to south measurement couldn't you extend the marks around the tape to get the height and the all you need is the distance from the top... not sure if that makes sense
The NFC tag can be hidden behind the glossy cover for the mount attachment. It's only held on by two all adhesive strips that run along the long edges of it.

If you extend the holes with a pencil to top side of the phone on the tape when you put it in the doc you know their location, then all you need is your measurement from the top and you are all set.. I dont have a laser like yours though

yea, that looks good. Actually looks shorter than the ones I used so I think it might be even better than the ones I used. Just did some searching on that site and found some that look similar to the ones I used http://search.digikey.com/us/en/products/829-22-003-20-001101/ED90504-ND/2416224. Looks like they come in a connector already but they're easy to remove from those kinds of connectors by just pushing the pins out. I like the style you found though. Ideally you don't want the lead part sticking out too far from the dock for a clean look so a pin that's just a hair bigger than the thickness of the side-wall of the dock is best. I say go with one of the style you posted over the ones that look similar to what I used.
Mil-Max (the mfg in the digikey ad) will send out a few samples. I got 20 to try and make my version of this.

I *think* that might work. I grabbed a set of (older analog) calipers to measure the pogopins on my LTE GNex and found some estimates. It looks to me that the pogopins are spaced ~.112" apart (from center to center) and are ~.042" in diameter. The pins you found on digikey list the spacing between each pin to be ~.100" apart (from center to center) and ~.042" in diameter.
With those measurements in mind, there would be some slight overlap of the outer two pins onto the plastic casing but the pins would likely still strike the connector on the phone.
Keep in mind though that a number of users have noted that the center pin is not used for audio. I have no personal knowledge of this but I am passing the info along. Apparently audio is passed via bluetooth to a receiver in the mount which converts it to a line level output that is seen on the mount itself.
(Also, I guess I cannot include the hyperlink you had because I am too new to xda)
Update: I stand corrected, as noted later in this thread the spacing is .118" for the GNex pogopins. Apologies for the misinformation.
The GN pogo pin spacing is 3mm (.118"). The All the Digi-Key pins mounted in strips seem to be .1" spacing which I think will be marginal, or at least make the position of the pins really critical.
This has already been done for the EVO 4g using Palm Touchstone capable scraps but I want to take it to another level. Since i'm not much of a programmer I can add to the community in this way.
Please let me know how many of you are interested in this. I'm going to put up full walk throughs as I move along but I will also sell some off (in the marketplace) for those that don't want to go through the hassle. I'm going to start ordering parts and building mock-ups and doing some design work during slow downs at work. I'll have a donation link up eventually if any one wants to help cover the initial costs.
-----------------------------------------------------------------------------
CURRENT DEVELOPMENT STAGE: 1- INDUCTIVE CASE RESEARCH, see #1
PLEASE KEEP AN EYE ON THIS POST (general updates) AND POST#3 (useful links and eventually tutorial)
:good:KEEP DISCUSSION AROUND THE FOLLOWING DESIGN INTENTIONS/ ABOVE DEVELOPMENT STAGE:good:
Design Intents are as follows:
1) A case for housing the inductive coil/wiring
This just requires compatible cases with necessary clearance for the inductive coil and wiring to the male micro usb. Cases with oversized bumpers would be best since they will keep drops from damaging the micro usb plug that will be sticking out of the bottom of the phone. This may not be ideal so if anyone is decent and making plastic molds maybe we could come up with an attachment to a case.
2)NO Hard wiring inside/to the phone
This involves using low profile male mirco USB type B connectors, like this, and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The main design issue here is protecting the male connector to the phone. Suggest usb connectors, wiring, how to boost the amperage, does the palm pre coil protect from over voltage, etc.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. Others are encouraged to come up/share your solutions as well! This should be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders out there keep that possible issue in mind.
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Current Progress: CASEAlright I have the cases in hand! I got three of them in the mail and will be tearing these apart this weekend. The pucks (touchstone bases) should be here sometime next week.
I'm also looking at the following cases
Ballistic
Ballistic 2
Clear S Case
The ballistic I am hoping will give clearance for the micro usb. They will be a bit heavier though... we'll see.
I going to order 2 cases for starters, what should they be?

Regarding the thread, this would be hardware development which i believe belongs in the general section. As for the idea, it seems like as long as its not too bulky most users wouldn't mind if it extended battery life substantially like 24 hours or more. Could make you rich with over 9.million sgsIII owners. But Im pretty sure there are already many types of chargers on the market so unless i missed something perhaps you should submit this to a patent office so no one steals the idea or design. Just my two cents dinner no one else has posted. But ya not software development so I would move three thread before you get flamed too bad.

This has already been done for the EVO 4g using Palm Touchstone capable scraps but I want to take it to another level. Since i'm not much of a programmer I can add to the community in this way.
Design Intents are as follows:
1) A case based solution, the ET4G is too damn thin!
This is just require compatible cases with necessary clearance and materials
that are least obstructive to the magnetic field.
2)NO Hard wiring inside/to the phone
This involves ordering male mirco USB type B connectors and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The only issue here is protecting the male connector to the phone. I've some ideas for this but will be very dependent on the case we use.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. This will be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders I'll keep that possible issue in mind.
Please let me know how many of you are interested in this. I'm going to put up full walk throughs as I move along but I will also sell some off for those that don't want to go through the hassle (is that ok on here? or do i need to set up donations?). Either way let me know because I'm going to start order parts and doing some design work during slow downs at work.
Thoughts? Concerns?
Oh and if you have other devices you would like this type of solution for I'm cool with that. Just ask and we'll work through it!
OH man... here we go!

I'm game! I tried doing it myself but I could only find the one spot on the USB plug to hook up to. I opted but to do it because there was some massive dismantling and soldering I would've had to do. I've still got the parts ready for when someone smarter than me figures out an easier way to do it though!

Technically, he is developing something. Just not code.

great idea. i have 4 touchstones kicking around. would love to be able to use them.
Technically, this IS "development"
Anyway, I would be interested in this myself. Seems like a great idea. I'm pretty handy & I have a welder/soldering station at my job. Would be happy to help out.

I would pay money for this...

This sounds very cool. And technically this is development. Just not software related. So I don't see where else this could go.

Just a thought.
What would be the charging time using touchstone/conductive charging; or in other words, what would be the output voltage/current provided to the phone. It takes a while on regular chargers to charge the phone compared to HTC phones.
haha I actually did this too my I500. Literally car kit and everything. Even had it play music through Bluetooth. except I hated cases on that phone so I hardwired it. looked so much sexier. But the case is easier. Built like that too just didn't have the car cradle

True
How much would this be for a car charger and home charger wireless
Sent from my SPH-D710 using xda premium
I have 2 palm touchstones, 2 old fried pre & pre2, and 2 phone backs for the touchstone charger to integrate with the phone..
I would absolutely love to know how to integrate the "guts" of the battery cover with the needed parts into the e4gt innards to make the wireless charger .. but I'm not sure how yet.. :/ I will keep reading and post here if I get it working..
I assume that the physical connection is totally possible but the OS will most likely need to be able to control voltage and jazz so I'm not sure what would be needed for that part..

Thanks for all the interest and offers for assistance. Being that its my friend's birthday as well as my own on top of fathers day weekend I won't start any design research until Monday.
I have ordered some parts which should be here late next week. I am still trying to find a source for some type B micro USB plugs. Guess I'll shoud stop throwing away those electronic component magazines. I did a quick search and found some but they were $6.50 each with $10 shipping. If any of you have a source for these let me know. Hell you can send me spare cables and I'll deconstruct them if I have to, but that's not very fun.
When I get on my PC I'll add a poll to see where you all would like this topic to be. Then I'll ask you how do I move it

Lets do it!
I actually got the touchstone and pre back and ripped out the inductive charging circuit just for this (I actually got it for my evo, but I upgraded before I had the chance to follow the evo guide). I'm excited for this!
Anyway - some heads up - the E4GT is MUCH heavier and bigger than the pre. Don't expect it to stay firmly attached. It will stay okay, but you need a really thin back face of the case. You may also try replacing the thin magnets with thicker rare earths. I actually got it under the stock cover okay, and that worked decently, but no good way to attach it. That's where I quit (after thinking about soldering to the board, but not having a good place on the USB connector without taking the phone all of the way apart. I also didn't fins another point on the board to solder to (like the charging circuit), although I'm sure it's there somewhere.
Also, you need to mount the inductive charging circuit a little low because the phone is so long that it will hit the table and not mount properly if you put it in the middle. Furthermore, be ware that if you add a connector to the USB port, this will exacerbate this problem, perhaps to the point of requiring landscape or stronger magnets.
The USB connector you want are available at a number of places. Ebay has some cheap micro usb adapters (including right angle) that you might play with. If you just want the connector itself, it will likely be more expensive, but I suggest checking mouser or digikey.
Good luck! This will be AWESOME!
