I'd like to start it off with a wireless charging kit I purchased that comes with a receiver and transmitter.
The manufacturer is called Yijieneng.
The receiver fits underneath the battery door with no modification required.
From what I've noticed about it, it charges a little faster than USB but not as fast as an AC adapter. (according to the receiver, it charges at 700mAh)
NFC works with this kit.
As far as I've noticed, the range is about 4mm (from transmitter surface to battery case) for there to be a successful charge.
The transmitter emits a small beep when it starts the charge. I've had it next to my bed for the past few weeks and I don't hear it when I sleep if it goes off. It does keep my phone at 100% in the morning.
At this time I'm also creating a custom dock that will put the phone up at an angle like a dock. I have finished the core part of it, but still waiting to finalize the ridge that will hold the phone. I'm waiting to get a certain bumper case before I create the final ridge.
Here's a few pictures of the dock in its current form (it still needs to be sanded and have the surface reworked):

Here's a video of the kit that I shot showing how it works as well as NFC function.

I bought a Nokia wireless charging plate uses Qi standards, I got it from Verizon Wireless online with my work discount, It cost me for 40 dollars and I am using Yijieneng Qi pad.
My s3 use UAG case (Urban Armor Gear), It does transmit the wireless charging through the case and It runs like charm.

As far as I know, the charging distance is between 4mm to 4cm (if the transmitter is based off the newer standard)
Charging speed
Depending on the receiver it can range from 500ma to 700ma (this is roughly the speed of usb charging or a little faster)
Does NFC Work?
I can't vouch for ALL the Qi kits out there, but the Yijieneng one that I do posses, works. Reference the above video to show that it works.

Yijieneng kit. Comes with a receiver pad that fits underneath the battery door and a transmitter.
Warning: I highly suggest getting just the receiver pad from them rather than the whole kit. Apparently the 2nd version seem to be problematic and requires an exact placement. You can find the transmitter at your local phone store like AT&T and Verizon or get it from sites like Amazon and such for the Energizer Qi charging pad.
As for those who are asking how to purchase this, this is what some of the members have done.

Just read through the thread and I think I might consider the Yijieneng receiver and charging pad. For those of you that have successfully purchased the kits from Yijieneng: How was the communication service and shipping promptness from them, and what's the price for the charging pad and the receiver (as they don't have any price listings on their site).

Hi,
Communication is slow, use messenger links on their site.
Price of the unit is 55$ + shipping cost. Mine shipping was 30$ via DHL.
Took them more than a week after completed payment to send the item. I was about to contact paypal to help me get my money back ...
grubia said:
The prices are from their pricelist which you can request and the prices are for "sample". Prices for bulk are more than half way down ...
With the pricelist they've send me 2 pdfs with company presentation. They seems to be big oem manufacturer for the most of QI enabled charging pads (incl energizer). But this is only if you can trust what is written in presentation pdfs and in my experience with Chinese companies like this is that the truth in presentations is less than 40% ....

Disclaimer: Touchstone, Qi, and Powermat are not compatible with each other. As of this edit (12/15/2012), none of these charging standards and their products will work with the other's product no matter what anyone tells you. In the future, there might be a universal charger, but right now, none exist.

EDIT: Added some extra info
EDIT 2: There are many members who have asked me where I got this kit from and the best I can and am allowed to disclose is that you would have to look up the manufacturer and contact them yourself. As far as I was reading, various members have actually directly contacted the manufacturer through their website and did their own transaction there. I personally have not done it before so I can not guarantee anything. I also do not know how much they charge nor do I know what kind of payment they take so your best bet is to talk to them. I only have this one kit that I have shown in the video and no it will not be sold to anyone (I like it too much and use it too much for me to even think about giving it up)

I'm such a sucker for stuff like this. But I have a hard time spending what looks like 85 for the pad and receiver for something that I most likely won't be able to use on my next device. This would be high on my list if I was capable of keeping a phone for over a year! :silly:

The charging base can be used for other qi compatible phone, so it's not a waste, while the receiver, it can be modded to support other phones.

Absolutely valid points. However I think I'll let the technology mature and adoption to increase a bit more. I'm sure prices will drop drastically.
Just wanted to post a walkthrough video of the Droidax EzyCharge Wireless Charging kit. I'm really considering opening the case up and seeing what kind of receiver is inside and possibly fitting it under the back of my phone and if I do it I'll update this post. Otherwise, I think its a great 3-purpose combo (case, wireless charger and backup battery) especially for the price when compared to the competition. The pad can be sold seperately and charges any device thats Qi compatible so thats always a plus. If anyone finds a cheap and slim Qi receiver being sold stateside let me know I really want to get a couple. Thanks!

The technology is already actively used in Japan, but it has yet to receive a wider audience. Some phones also come built in with with Qi wireless charging like the Droid DNA and the Lumia 920. Hopefully there will be more and more devices that have it built in and then hopefully the "battery covers" for those phones will be sold on sites like amazon or ebay that comes w/ the qi receiver that you can remove and mod into the s3..
I also have the kit in the first post. I like it well enough. I use it at work all day. I am having an issue where I cannot receive phone calls while charging on the pad. Anyone else experience this? I have the leaked jelly bean k1 build. Just stock leak. No mods. Any ideas?
i get calls all the time even while it's charging (especially those damn telemarketers) .. i can take a ss later of my screen when I have it in the base.

Dose it matter what charging pad I use? seems like you can get a back plate off ebay for $16 but dont want to spend the 50 on a QI pad.
so Can I just get any charging pad or dose it have to be the QI to work or are they just universal?
If the backplate is a Qi compatible backplate, then yes it will work. If you're talking about the palm touchstone mod, then no. They operate on a different frequency.
This applies to all the different standards. As far as I've read, no standard are intercompatible with the other.
i.e: Qi will not work with Touchstone or Powermat. Powermat will not work with Qi or Touchstone. Touchstone will not work with Qi or Powermat.
They send out a different set of frequencies that the other standard does not use/accept.
thanks. that kinda sucks because they sell the other powermat for $10 bucks but QI is 50.ill have to check out the frequency it uses and see if I can find an alternative.
I remembered that Powermat claimed it will work with Qi back in early/mid 2011, but doing a search has shown me nothing. If you order from amazon, you can probably try the powermat transmitter and see if it works, then return it if it doesn't, but I highly doubt it considering they're competing standards.
I'd love it if Samsung came out with a Qi charging kit since it seems to work so well but at this point I'd be happy with anything from them.
samsung is too busy flip flopping between 2 different standards. the contact points are there, you should be able to purchase a zens or yijieneng receiver and get a cheap transmitter from energizer or something.

The impression that I have gotten is the AT&T version of the Note II supports wireless charging without any modifications. Is this correct?
If so does anyone have any suggestions on charging mats, or are they all pretty comparable?
If you mean without using a charging dongle, someone hacked their back cover with a palm charging coil; it's in the threads somewhere. Out of the box, no.

I actually called Samsung directly about this, but unfortunately the sales rep couldn't tell me what future accessories they plan to introduce for the Note II. I'm crossing my fingers that they do.
You can purchase a pre-modded charging back for $40-50 dollars online. Don't need to modify anything on the phone.

eBay. $40 for the back cover with NFC and wireless recharging capabilities. $75 for the back cover and Palm Pre wireless recharging dock.
I'm sure there's other places that sells them if you look in Google Shopping.
Only drawback is that recharging takes a long time. Possibly because the Palm Pre is a smaller device with a smaller battery.
On a side note; If I get impatient enough with Samsung, I might just buy a spare back cover, and (using the given steps by other users of modding the back cover to allow wireless recharging...) test out ways to increase recharging speed.
The TouchStone for the TouchPad charges at 2A. But, I don't think it's magnetized like the version for the Pre, and a lot more. I also don't know if you would need the coil from in the TouchPad or if the one in the Pre back would take the higher output if you used the TouchPad's base. I have a TouchPad and TouchStone for it. But, it all sounds like a lot of trial and error, and may turn out more expensive than the official one from Samsung, when they ever release it.

I agree. This 30 pin connector, proprietary charging, no HDMI, coupled with no JB 4.2 so no miracast, this is one disconnected, connected, wired and shackled but supposedly mobile device.

my playbook, and my note 2 use 2 amp chargers. I just lucked or on the 30 pin connector because I had a mini usb to 30 pin connector for my tab 2 7.0, and an extra cable.
The tf300 was a dream to type on with the dock, but honestly, my note 10.1 kicks the crap out of it. The oem cover works great, with the exception of a lot of e's that come out 3.

I had no idea that this was happening.
It would be awesome if Samsung could come up with a transformer-esque type of keyboard/cover, or even a touch-cover like the Surface.
It makes the idea of a "Note netbook/laptop" a good one, but with two separated accessories i.e. stand + bluetooth keyboard, that idea is gone.
Shame :/
The tablet must be a tablet, not a computer if you want a computer buy it separately. A tablet is made for commands through touchscreen, if you want to have a tablet with dock keyboard buy a tablet-pc ( i own one..)

Eh? I can find the Samsung connector (which is actually a standard called "PDMI") just about anywhere (at least in the States), I've got more charger options now than i had with my Moto Xoom, especially if you buy one of these. HDMI and AllShare Cast work on my device, too.
I've used 4.2 and we're not really missing much useful save the multi-user feature.
I have 4 BT Keyboards, including one with a built-in stick mouse and a cover that folks to make a stand; the combo (which is light enough I carry it around in a case with my Note) gives me everything I could get with the KB dock except maybe charging and it's apparently more portable as well.

I went to verizon yesterday & saw a Samsung branded Keyboard dock for the Tab10.1. I tried it with the display model Tab 2 10.1 & it fit. I thought that the Tab 210.1 & the Note 10.1 were the same size. I was gutted to find it was not. It works if you pull out the plastic guide/holder, but then it is kind of flimsy in there. Bummer.
Wasnt there a rumor somewhere that one of Samsungs next tablets was going to be transformer-esque? I could have sworn I read something a few months ago about it.

Well, with the GNote 10.1 LTE coming to VZ soon, I'd expect they'd be getting accessories there, too (and likely to be hugely overpriced), so I'd come back again a little while after the GNote's available in VZ stores.

That sounds sort of narrow-minded in my opinion. Why can't a tablet be both or why can't a computer be a tablet? For an artist like me, I would love the opportunity if tablets got powerful enough to rival their notebook counterparts and offered a desktop view as well as for easy access with a keyboard and trackpad.
With the move of ultrabooks , especially the Surface Pro, converging into tablet territory with full features, one must consider that to be a blessing than a curse. Think about it in this way: Would you carry a radio, cd player , portable DVD player with TV, game system and an ereader just to be able to use them, or would you opt for the simpler solution of an all in one deal? That is the number one reason why the iPod took off: portability. Not only can you get a radio, but a music player and now video, games and reading.
It gets roughly cumbersome to carry every single CD, DVD ,game cart/disc in addition to the hardware , let alone the books for brief reading in commutes in comparison to an all out deal.
For the average consumer and artist, such things are so hard to get that it is pushed towards the rich ,but now similar tech now exists that has the potential to allow for maximal power and capability and the ability to change form factors on the fly. Why should people have to be inconvenienced to buying several different products that can be brought under one device when it can be deducted into one singular product that is amazing and does it all , broadly speaking?
If we went by this flawed logic an mp3 player must play music only, but no radio , thus how would iPods and whatnot be popular if they didn't serve multiple functions simply?

Thanks.....I think. Glad to hear about the PDMI. Just have to figure out how to use it.
What I was trying too say is everything is an add on so my kit ends up being as bulky as my ultrabook and far more prone to losing some piece that makes the whole thing work. my last tablet logged about 100k+/- frequent flyer miles. Using one power brick with one power end, one multi headed usb, one multi headed hdmi, one universal battery charger brick fit neatly in an airplane amenity bag, and served two cameras, one phone and a tablet. Needed no OTG cable to get the CF card reader seen by the tablet. Because I have a GNex, I already have a data/sync switch on my usb cable.
The cameras are the hardest and heaviest to carry.
So far, I've had to add another amenity kit to add the adapters for the Note. And I still don't have a way of using it to run a projector or tv. My phone ends up doing that.

I'm designing a dock for the N7v2 for use in a car. It will have Qi wireless charging and Bluetooth audio receiver, with a standard 3.5mm audio output. It should be compatible with most cases.
I am also currently designing a mounting method that should be close to universal between different cars, and should not fall off like most other docks in the market.
I designed one for the N7v1 using the Pogo pins, and I can never go back to not having a dock for my tablet in my car. It's amazing the difference it made for me.
I want to know a couple things.Please reply with the following template:
1. Would you want a dock like this?

Sounds like a great idea. Do you have any links showing your work with N7v1? Heck, I may be interested in that version since the v1 tablet can be had for cheap these days and is more than capable for the limited functions needed in a car. At any rate:
1. yes, would be interested
2. no idea what a fair price would be, but $50-$100 seems like a fair ballpark
I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?
The wireless car mount/charger iterations for the Nexus 4 were a failure, I recall.

Sounds like a great idea. Do you have any links showing your work with N7v1? Heck, I may be interested in that version since the v1 tablet can be had for cheap these days and is more than capable for the limited functions needed in a car. At any rate:
1. yes, would be interested
2. no idea what a fair price would be, but $50-$100 seems like a fair ballpark

I've attached 4 pictures of the dock I made for the first Nexus 7. You'll notice that it inst exactly a dock you can put in just any car. I realized I made a little too rugged... and big!

I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?

Well, that's why I don't leave the tablet in the car, I keep it with me. While I'm in the car, if it's hot out I will have the A/C on anyways, so heat has not been an issue.
Most of my broken devices are dead because the USB port broke because of wear and tear. One of the points of this dock is to reduce that. Plugging in a device everytime I get in the car is partly to blame for such failures. I would have used Pogo Pins, like with the first Nexus 7, but they don't exist on the second.
Shared app developing ideas
Hey everyone,
my name is joseph and i am new to this website. I am also new to the whole rooting phones as well as i am learning the basics of computer science-- os, rom, ram, eprom, android, custom roms.....etc.
I honestly have no idea what i am looking to read and study up on so if you have any ideas than please let me know so i can educate myself. I end goal is to be a program developer.
Also i have an amazing ideas of a great new app. I have the layouts for the app but don't have the knowledge to build the app myself. If you are interested in learning more about my idea and possibly collaberate pleae let me know and we can possibly exchange numbers.
Another thing, i am an inventor and creator.

Look at active Brodit car mounts - say for a Nexus 4. There the device is supported and aligned as it glides onto or off the USB. There is no possibility of twisting or yawing.
I think your proposal maybe over-kill - simplest solutions are always best IMHO. A guy in the Nexus 4 forum came to no good end and had a lot of unhappy 'subscribers'. Just saying.

I would normally agree. I was hoping to make one that doesnt require a case to be removed to use. I designed my previous dock the way you describe (except it used the Pogo pins on the side), but I always had to remove the case and eventually the first case was showing signs of damage from being removed so often.
My hope is that the base platform of the dock I want to build will be compatible with multiple models of smartphones and tablets that are Qi capable. That'll require a lot more planning, but may be worth it.

Well if you're set on the route you've described; ... I see you've picked up on the Peltier pump in another thread. Credit me somewhere if you make it!
But I might consider an approach made by Philips in an Android Bluetooth Speaker and dock. The adjustment for USB and its placement on an edge, plus 180 degree rotation needed for some models, was catered for physically. A much cheaper approach which copes with tablets and phones!

I think I will use a Peltier pump. And yes, I'll make sure you get credit for that idea I'll mount the transmitting coil onto the cold side (probably with a layer of copper in between, we'll try several things) and have the hot side of the pump mounted to the aluminum/sheet metal of the back plate (probably with thermal paste as well). I'll have the pump on a simple thermostat. Good thing I have an EE helping me with this project
Hopefully the final product won't need a Peltier pump, but I will definitely have it in the prototype.

I haven't had very good experiences with using that type of dock The results of daily use tend to be USB ports that are stretched and loose. At least that's how it has been in my experience.

Don't forget to talk to your EE about eddy current loses in any conductors (copper, aluminium) you have nearby to your induction coil.
Interesting read, but with the cooler this is going to be a very expensive dock. Without it, look to Canada for your market.
I rigged up one for my Nexus 4 last Winter. Based on some testing, I used the most efficient charger I could find for that phone (the LG wcp-700). It worked very well... until late spring when the mercury broke 70. To make a long story short, I pulled it last month as the phone was getting too hot. This in a suv with a 4 liter v6 with plenty of air conditioning, front and rear.
Without the cooler, the tablet needs to be located directly in front of a vent, or even in moderate climates the unit will get hot enough to significantly reduce charging current.
One more thing to consider... the Nexus 7 is polarized vertically. This means that it is invisible in landscape orientation for anyone wearing polarized driving glasses, which I am willing to bet is a large percentage of your prospective market (tech savvy, auto enthusiasts). Most displays designed for vehicles are polarized at 45°, making this not such an issue.
While the tinkerer, software developer, and electronic geek in me wanted a fully integrated tablet in my truck, I soon came to the conclusion that it was simply not practical. What is really needed is a properly done appRadio, where a head unit can mirror the display of a mobile device (ideally wirelessly - miracast, etc.) with a control link set up to pass touches on the head unit back to the mobile device. We're about 30% there now, but a lack of standards, and major players wanting proprietary solutions is a problem.
I wish you much success with your endeavor, but just wanted to share my experience and feelings that this will not be all that marketable a product.
The problems you had with the nexus 4 does not necessarily effect the nexus 7. The nexus 4 was pretty terrible at wireless charging. I had a car setup with a qi charger with the lumia 920 and it worked great even in hot weather. I am not saying the nexus 7 will work, but it might.

What makes you say that? I ask as I have seen relatively similar performance with both the N7 and N4. The tricky thing about the N4 is that the coil is not centered in the vertical dimension, so for folks making the assumption that it is, there will be quite a bit of offset.

I say that because of all the issues people had with car docks. It also had issues with the dt-900 qi chargers when it shouldn't have. It heated up excessively with most chargers.
I wonder if there will be an Official dock that lets you:
1. Charge
2. Expand TV HDMI out
3. USB port for Hard drive access
I really want the Nexus & FHD to be a Home entertainment player...may be a remote/ Or Kinect like gesture control app built in with the dock
Hope this comes true...it will be the best Combo for a home unit!
All options seem to have a huge lip of leather coming off the bottom portion right under the touchpad, or need a kickstand for support which is not practical on your lap.
Any suggestions?
I bought a Motorola KZ-450 combo keyboard/trackpad that's got a protective cover that turns into a stand about two years ago on one of those "Deal A Day" sites for $30 or $45. I keep it in one of those generic cloth 10" tablet pouches along with my Note.
My only regret with it? Not buying two at that price- it's been pretty much perfect for me, and I use it to bang out E-mails when I'm flying.
Any other options out there with a trackpad? The motorola doesn't seem to be available in the UK
Been looking for something similar myself.
All I've been able to find are touchpad based solutions...not that practical
I was looking for the same until I ordered this today: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
I describe why that one won out of the 100s of keyboards I was checking for certain features (priority, quick switch, multi-device pairing, lower priority, trackpad). Not only does it have both of those, but also a built in IR (learning) remote! Check out my post in the other keyboard topic on this page, where I describe it a bit more. Hope that one appeals to you!
Bad link
My bad, thanks for letting me know http://www.amazon.com/Ultrathin-Wireless-Bluetooth-Programmable-Rechargeable/dp/B00EZL1N6U
what about this one?
http://www.amazon.com/Perixx-PERIDU...1-9&keywords=bluetooth+keyboard+with+trackpad
I use the Logitech K410. Perfect and not too pricey.
sorry for the bump but... does k410 works via bluetooth ot you use the USB dongle with a cable?

I wasn't part of this thread, but I hvae used logitech products with my android devices that were meant for windows. I have my Trackball M570 and one of my wireless K800 keyboard both connected to the same wireless dongle. When I want to use them with my Note 10.1 2014, I plug wireless receiver dongle into an adapter, like this OTG cable: http://www.amazon.com/gp/product/B00GM0OZ4O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
So, it connects wirelessly as it would to the pc, not via bluetooth.
Only other thing to note is, the apps Logitech has for Android keyboards will not work with things like the k800.
There are miniaturized keyboards with touch pads and often a remote control on the other side for smart tvs. But these are wifi based, maybe additionally with bluetooth. Or there's some wireless remote(the wifi ,not IR kind) or wifi keyboard driver/app for Android.
I found this one
http://www.amazon.it/LEICKE®-Sharon...kmr0&keywords=tastiera+touchpad+note+10.1+014
It's very cool, but they don't sell a version with Italian layout (And the keyboard is not attached to the cover, but you can fix it with some glue XD)
Do you know something similar sold with different layouts?
