So I'm really missing wireless charging after having stuffed it into my GS3 and the Nexus 4 obviously having it built in. So... being that I still had 2 chargers and 2 pads left over, I've decided to begin modding the Moto X after seeing there was quite a bit of room in the bottom of the phone under the battery cover when I was replacing the woven black with a MotoMaker back. Here's the pre-fitting photos. I had to trim some of the foam away at the bottom, and still need to trace where exactly to place the wires for the charging. I'm guessing I'll have to solder directly to the back of the USB port. Where it sits will be a perfect angle, and should not interfere with NFC at all (Yay google wallet!)

I'll be posting periodically with updates, although I don't know when I'll have more time as I have 2 infant daughters that demand much attention.
Awesome!
I've been missing qi charging as well, hopefully you get this to work.

Curious to see how this goes. Even though I am quite sure the results will be positive.

I hope you don't abandon the idea and keep us updated. Seems like a worthy project!
Go OP! I can't wait to see success with this, so that I may be able to do this mod myself as well.
Exactly what I was hoping someone would do. Hopefully this works out and is simple enough to do. :good:
Looks awesome, OP!
On a side note - where did you get the MotoMaker back? I'd like to change my back to a custom-colored one eventually too, but I haven't been able to find any backs online.

You can get them on ebay now. Been eyeing getting one but waiting for the wood backs.
Well this is awesome man...!!!!! :good:
Wow, god speed. I don't yet have a Moto X (still holding out for a wood back) but I'm so used to using those Palm wireless chargers on my current phone (SGS)! I have one at work and one at home on my nightstand. It's a perfect angle of inclination for my preference and the wireless charging works great. Are you having any problems putting the phone back together? I know they don't leave much room in there for something as thick as one of these chargers. And I guess if I eventually get the wood back that probably wouldn't make for an easy time getting it off :-/
I'd like to do this too, which coil receiver do you recommend?
Thanks,
Danny

The one he is using in the images uses the Palm Touchstone charger, you can find a bunch of applicable coils on ebay: http://www.ebay.com/bhp/palm-wireless-charging I am fairly certain that this coil will only work on that Touchstone and is not compatible with QI or Powermat.
edit: I also highly recommend buying some tiny magnets (I bought 1/4" by 1/32" circular ones) instead of the metal disks that are included so you can get it to snap a lot better to the stand.
thanks
Anyone trying this should aim to have the charging coil as close to the camera as possible, the antennas are all in the lower back of the unit and you won't want to block them at all.
I have been looking at some wireless charging options myself. One of them is a small pad that should fit under most soft cases, it has a thin ribbon cable with a very low profile micro usb connector on the end. The better option is something like that but integrated internally. I haven't opened a Moto X yet to see how much space there is. What is the maximum thickness we can hope to have, is there anywhere near 1mm if we remove the silicone pad?
Everything I am looking at is Qi compatible.
I have also been studying high-res pictures of the inside of the Moto X looking for possible solder points for power, doesn't look too friendly at this point.

There is plenty of room towards the bottom and the silicone is maybe a mm in the thickest area. Insofar as blocking the antenna, I've never had issues with my sgs3 or note 2 with putting the coil over the antenna. However, with regards to solder points, you are right. This is not going to be easy without fully disassembling and finding either the microUSB solder points or the charging circuits entry points from the microUSB. I may be abandoning this if that's the case.

That looks like it would be perfect to slip between the phone and a case, would bending it to conform to the back of the phone affect it's charging ability though? Or would it even be able to be bent?

So how would one check to see which of the 4 prongs connected to the ribbon going to the battery are the correct +/- terminals. I've been studying over the iFixIt.com images to come up with a plan and I think if I can get a random wireless charging coil from eBay then cut that ribbon to fit into the 2 needed ports for the battery ribbon, then the only thing would be size/fitment under the back cover.

It shouldn't matter. As long as the plug is in, and the pad is near the wireless charger.
This is kinda smart; can't believe this isn't widely known. I've never seen something like this.

I managed to put together a google sketchup model of a galaxy nexus horizontal dock with extra battery charger. It has quite a ways to go but it is a nice start. I am going to get my buddy to print these out with his reprap printer this weekend and we will see what needs to be done.
Goals:
Use pogo pins to charge nexus
auto charge extra battery
have the dock hold the phone sturdy enough
*Update 2/16
I went to my friends house to get the parts printed out and lets just say it wasn't pretty. I haven't done any 3D printing before and it showed. I got some tips on what to change to get the part to work better in the printer and I will be spending some time this weekend fixing the model. The good news with this is that the new design should be extremely easy to change for different phones and phone shapes as all I will need to do is change the part that holds the phone, the rest of the dock can be reused.
Also I finished the schematic for the battery charging circuit. I will post a full schematic as well as a board layout when i actually put it up on a computer, right now its just a sketch in my notebook. The basics of the charging circuit is a National Instruments LP3947. This chip provides battery level monitoring which will allow the battery to charge to 100% and not overcharge or overheat. As for the power supply, I haven't decided yet. It is ether going to be a 2 amp plug or a 1 amp micro USB plug. The pogo pins are only rated for around 600mah and it is recommended to charge a battery at 500mah or less so I might just stick with using a micro USB plug to keep things easy.
* Update 2/18
I had to redesign the dock from scratch because as I stated before google sketchup isn't great for 3D printing and the model I tried to print failed pretty bad. I took my friend's advice and tried to chop it up into smaller pieces. I am going to print these out in a few hours and will post results this time. As for the schematic, I will get to that when I can. Getting a new model done was more important.
As you can see in the picture the dock is in a lot more pieces. Hopefully this means I can quickly redesign each part that is needed if something doesn't come out right in the print without having to print a whole new model. Also with more pieces anyone should be able to adjust this for any phone or case. The tray that holds the phone has room for another 3-5mm of thickness. I am not sure how much room there is width wise though.
* Update 2/19
Printed out a few parts, only two came out so I will give that another go when I have time.

Planning on mass production? Count me in for 1
Whenever I get it.working I will post instructions
If this had solid build quality I would definitely be interested. Especially in pogo pin charging capabilities.
If you decided to make one that fits with the cruzer a2 cases, Id def be in for this. Id even throw 1 in for ya if you dont already have one so you can get the stats right.
solid idea! hope you make it happen with all these delays on the official dock.
I'm very interested. Especially if it can incorporate pogo pins.

I have been thinking about this for a few days and I am a bit worried that people won't like the printed plastic finish. Since I am basically only making this for myself I am going for function over form. I only have access to a RepRap 3D printer and my own PCB etching stuff, so no nice injected plastic. If people are still interested in buying one instead of just building one from my instructions that I post when I'm done we can talk then.
Very much looking forward to this! It's similar to something I'd love to do myself but I graduated in December so I no longer have access to my school's rapid prototyping lab.

I'm sure there will be a lot of interest for this, since Samsung bailed, regardless of form.

Hey thanks a bunch! I will give these a shot (I checked the spacing on the battery and it seems to be 3mm like the other posted stated)
I didn't want to clog/hijack THIS THREAD but the pin info and idea was very helpful. After waiting and waiting and waiting for official word of a charging dock that utilizes the pogo pins on the side, I've given up hope. And lets face it if you kill the usb port on this thing "you're screwed". so I really wanted to reduce my usb port usage and utilize a feature that comes with the device.

My material list is 8 screws, 46 gauge guitar string, a strip of 1/2" playwood that happened to be ripped down to 2 1/2" in my garage, usb cable, piece of flat 1/8" thick plastic and a tiny bit of solder. The way that I screwed/bent the piece of guitar string gives the perfect amount of spring so that when the device is set both are compressed and make contact with the side of the device.
This was very spur of the moment and took me a half hour to build. And it works brilliantly. Yes I could have spent more time on design and material type and getting proper pogo pins. But I'm lazy and intent of this thread is spark ideas in other peoples heads. So now this masterpiece lives on my nightstand and I drop my galnex in at night and wake up to a full charge in the morning without having to use the usb port.
**edit** The pic of the lockscreen is in landscape using the Team Kang AOKP rom.
good day.

I love this, but I got some questions I'd like answered before attempting this.
1.For those of us without guitar string, would a paper clip bent into proper shape work well too?
2. What cable is that, that you were using just a power cord or was that usb?
3. You said it just sits on your night stand so does that mean you cant transfer data to your computer?
Also a video just going over it more or perhaps some more pics of the back there would be nice (at least for me) to see what is screwed around the screw.

1. no idea, sorry. Check out the pogo pins though.
2. Thats a power cable, a usb would have a wire for data.
3. the pins don't transfer any information (well... the middle one does, but not anything useful to a pc) so transferring stuff would be impossible. (but thats what wifi is for)
This is beautiful and ugly at the same time.
One thing I would recommend is cutting out an area at the bottom of the phone so that you COULD attach a USB, OTG, or MHL cable if need-be. Perhaps that side of the dock could be shaped like a B, or notched to also allow access to the headphone port.
I would also maybe split out the power connection to a microUSB port to power MHL or other accessories. Or maybe just wire up a fullsize female USB to power another unit such as a bluetooth headset or whatever. It just would be nice to have a powered USB port just in case.
To the guy above, sure it may not look perfect but a coat of paint would spruce it up very well.
Overall A+
I might try my hand at something like this. I'm a cheap ass when it comes to buying crap for phones (since I go through them often). I have all the materials already with the exception of spare guitar strings but the paperclip idea sounds great and can be bent to size. I have some Poplar wood in my basement that would even look good with a heavy clear coat.

You may encounter trouble because of the One's all-metal body. Your case will need to completely isolate the coil from the body for this to work, if memory serves me right. Admittedly, it is aluminum, so I'm not altogether certain it will be an issue.

I would really like to see something like this. A couple of challenges I think would be keeping the plug area on the bottom to as thin as possible and second would be to keep the case as thin and small as possible.

Post pics of it on the phone and let us know what kind of charger your using. It looks like you could rip off that coil and place it in any case if it's thin .
Definitely report on results. I tried to make something like this for my One XL, and while it worked as far as charging went, it was unpredictable and seemed to make the phone unstable, though I could never figure out why. I suspect it's not just the charging current but that the phone's charging circuits and drivers need to be tuned for wireless.

Thanks for letting us know about this. I'd not seen that, but it looks like just what I'd like to try and fit between my phone and case. The lack of wireless charging was the biggest reason I held off switching from my DNA to the One. I love the convenience of just plopping my phone on the orb charger during the day.

I saw them but they were more expensive than the one I picked up from ebay and still come from China
they are supposedly 750mA so should be a bit quicker to charge than the 500mA one I picked up
I just received this
http://www.ebay.de/itm/111186469984...eName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Works good, put it between my hardshell-case and the phone. Looks like the amazon-solution above is roughly the same
edit: Yeah, same as mentioned a few posts above... sorry for that. So, I can at least second that it fits quite well and doesn´t stick out much on the USB-Port
any idea how to use these universal receivers on my THL W8S?
my camera and my micro-usb port are in the same side, so the wire will cover my camera.
does anyone knows about an item that has longer wire so i can bend it around my camera?
this may not sound like the most logical idea, but isn't it possible to somehow use NFC for wireless charging, since NFC is about near field communication after all?

Nfc doesn't connect to the battery of the phone and the coil is not inductive as it is a derivative of close range rfid
A quick tip for the add on qi pads with the HTC one, as the USB is not in the middle you can't position the pad straight up or the curved back makes it hard to get a connection. Put it on a bit of a diagonal so the pad is in the centre of the back

A lot of cool, useful information in this thread. Thanks everyone!
I tried this under a TPU case on my GSM GNex and it works!

Edit: there are cheaper listings for it, search and get it for less.

Interesting.
No way to install it using the stock battery cover?
Well I'm sure you could, depends on how thick it is. Perhaps a stock extended cover. I don't know about the extended battery though. It's pushing stock cases as it is.
I'm not 100% sold on the USB port and flex cable. I guess if you use a TPU case, this would mostly be concealed but I've seen these where they actually attach between the battery and battery contact inside the phone (double sided flex cable with copper connections on both side). That would be ideal and I'm sure it would work.
Similar to this one:
http://www.amazon.com/Samsung-Standard-Wireless-Charging-Receiver/dp/B00BCC2B1Q/ref=pd_sim_cps_16
It just bends to go in between the battery and phone contacts. These are also meant to go under the battery cover. Our batteries use 4 prongs, not sure if this one listed is compatible. I would buy one in a heartbeat if someone posted a link to one that works.
My N7 is Qi capable and I have a Qi Charger, but it goes largely unused. I'd use this in my bed room though for night charging. I'd like to keep the USB port open still for charging normally in my car or when traveling like normal.
Edit----------------------
I don't see any actual easy way to do this. The one I posted before actually uses battery contacts under the battery cover that is specifically for this. The Galaxy Nexus does NOT have these. However with a little engineering, it should be just as easy. The battery has 4 contacts. The battery is labeled with (+) and (-) pins. One could probably grab one of these for the Galaxy S3, turn it sideways so the contacts are close to the battery pins, and use some kind of copper foil to wrap around the battery tabs and to the Coil leads.
I use an extended battery, which leaves me with little room. I have been wanting to experiment with cutting one of my backplates in half to just cover the top portion around the camera, giving me some additional room for stuff like this. Probably wouldn't work unless I used one of my stock standard batteries. Losing a few mAh for Qi might be a good trade off though.
The mod would actually adhere to the battery itself, thus no physical modifications are done to the phone. So I could always pick one of these up, hack a battery, and test it.

I have broken my Gnex's micro USB port recently and I am going to change the whole part:
A broken usb port, believe me is very annoying and I am thinking of adding qi charging capability to my Gnex to reduce the workload my my new port.
I don't know if there will be a risk of overcharging if a qi coil is attached directly to the battery, as a qi receiver coil converts oscillating magnetic field to 5V only.
How about adding a LiPo charging circuit that will cut off when the battery is full:
This exact board measured 10mm(w) X 12mm(l) X 2mm (h), a minor back cover mod is need to install that.
I've waited so long fo this
Thanks for the tip!
I actually did this to my GNEX. Although not how I pictured before.
I actually took a soldering iron and melted the plastic under the battery door where the pogo pins come in. From there I soldered 2 balls of solder over the outer pin contacts. From there I just laid the Qi pad on it to make contact and taped in place.
I used a slim case, so it required I cut one of my battery doors in half and used a standard battery. Extended battery would kinda work but the case would buldge at the bottom making a poor fit.
In the end, I glued the Qi pad to my feather case with poxy. With the case on, it kept the contacts connected. All that was visible was a small hole under the battery door. Worked great. Don't even have to take it apart.

Um, it's not bad. I charged at night. I used a 750mAh Qi Pad, so it was faster then a slow charge but not quite as fast as a quick charge.
It was super easy. I had pictures up on Swappa when I sold it. If I can find the listing I'll post the link. It was probably the only GNex with Qi.

There's my post with pics of the Qi mod. Took a soldering iron and melted some plastic under the battery door, exposing the 3 pins. 2 solder balls on the outer pins. I squeezed a small piece of toothpick over the middle pin to provide separation. Then just laid down the pad and taped it. Took 5 min.
I squeezed all mine down to fit into feather case. You'll see the pics in the post. Pretty easy to follow.

I didnt know that that is even possible by an easy upgrade Thx! I will try it.
Has anyone tried one of these qi receiver tags that plugs into your Micro USB port?

I know they aren't optimal, but I figured if it works it would be a good hold over until good ones come out for the G3 specific.
I will let you know when my phone gets in, I have one left over from my LG G2. I don't see why it shouldn't work though.

Thanks. Any idea which one I should look at getting? Haven't seen a good enough shot of the micro USB port to make sure I get one facing the right direction. I've got Amazon Prime so I'll probably get one from there to test.
http://www.amazon.com/Universal-Wireless-Charging-Receiver-micro-USB/dp/B00H7FJX7M/
That one is on Amazon, Prime, and has 2 different models. Anyone seen a close enough photo to know which one we'd need? Port A or Port B?
I'm going to try to find one with a metal plug instead of this plastic one.
This one has tons of different options. Less than $11 on prime.

From what I saw in pictures, it should be this one correct?

If so I'll pick one up today so its here for testing when my phone arrives.
Yes I got one and didn't work.
Didn't charge at all? Can you give us some specifics?
No didn't even register on the phone. It was only $7. I ended up ripping out the Quick Circle charging coil and putting it in my phone. Works a treat!
Thanks. Do you know exactly which one you used (perhaps a link to where you purchased) so those of us that want to test other ones skip it?

Im using this one; http://www.amazon.com/gp/product/B00HI8JYFE/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
No problems after all. Working OK with my F400K
So now its working? Awesome! Buying 2 right now.
Mine works as well, I have this one: http://www.amazon.com/gp/product/B00IQ2GUFI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
BUT it only works if i have the receiver stuck on the back of the phone in between it and the phone case. If I have it on top of the battery the signal doesn't make it through.. perhaps because of the curved nature of the phone and the NFC receiver on the inside of the back cover.
I was always under the impression that NFC and wireless charging interfered with each other unless it was one integrated unit. That's probably why yours only works that way.
Well I got mine and tried it out, and while it does work, kind of, I'm sending them back. The cable ribbon is so thin it feels like it is going to rip, it would also need you to bend it at a bad angle to get it inside a case or inside the back. I can't get a GOOD charging connection with my TYLT VU chargers, so it is going back.

The cable ribbon is probably thin because you need to bend it at weird/sharp angles and it has to fit in the cracks of the back or case. As long as you're not constantly pulling on it, there's really no risk of tearing. Connections are fine with my $20 chargers, I can drop it on pretty much anywhere in the vicinity of the receiver and it'll charge.
Charge rate depends on which receiver you go with. Most, including the ones posted here, are 500mA which is kind of slow. I should be getting an 800mA one soon so hopefully that'll pick up the pace. IMO, these are still better than switching to PMA.
Its not so much the thin that bothers me, it is how flimsy it is. I mean it could have some reinforcement of some kind you'd think. And it leaves the pad really low on the phone, probably part of the reason it doesn't connect well even with a QI pad a good as the TYLT VU. Just removing the thing to root my device was scary, I thought the USB plug was going to tear off and stay in.
I just bought 2 battery covers with integrated Qi/NFC for $23 each on ebay (my wife got a G3 also) so that should fix the issues for me. Not sure what the VU charges at, but with my Nexus 5 it was always great, for a heavy user like me, I was satisfied (Qi dock in my car too).
What kind of qi car dock do you have? I love the wireless charging and have seen a few posts you put on XDA. I ordered that back plate from eBay, hopefully it works OK and I had ordered the sticker from China but it seems like a pain in the ass ripping off the old one.
