I have opened up a cheap QI Wireless charger for a DIY project, I am looking to extend the distance between the PCB and and the coil but not sure what type of cable to use or where to get it from. I am assuming it would be copper cable of some kind? Anyone done the same or got any advice?
I was about to write that a pair of thick wires will do (something at least as thick as the ones in the coil). Then I did a search on Google and checked another thread that I happened to have opened a few seconds after yours (just checked the new threads in this section).
So check this guys contraption. I don't know if there's a difference in charging time due to the mentioned cables, but I guess he's the one with the most experience around here.

Thanks for the reply. That thread is where I got my inspiration from and you may notice that is it only back near the top of the forum because I asked my question there too shortly before starting this topic.
Just be careful where you put it, not to have a too thick panel between the coil and the phone. It will reduce the charging efficiency.

I am looking for the points in need to solder the wire at.
I am looking for something similar to this:
http://forum.xda-developers.com/showthread.php?t=1557923
If you look at his third picture he soldered it to a resistor because he thought it was easier that way. I would prefer the same thing. Unfortunately this is the guts of an ATT S2 and it seems dif than our tmobile one.
If someone could provide this with a nice pic pointing out the spot that would be great!
Thanks.
now i dont know about any solder points but what i did was to remove the back pannel and exposed the the carger port which is connnected to the usb port..then i went to my local hobby shop (here in the midwest i went to hobby lobby) and $6.99 later i purchased copper tape. what i had done was to look at the battery which is labled where the positive and negitive terminals and laid the copper strips accordingly, now on the other side i made sure that the inductive coil was also in line so that when i placed the battery cover on the back of the unit it will touch the copper tace lines. All i have left is to see if if the touchstone works ( i still have yet to purchase that...) and it will be complete. Now also i have the verision galaxy nexus extended battery installed and some how it all fits. once i have figured out how to get the pictures to show up from my flicker account i will repost them.....heres some quickie links (backdoor) http://goo.gl/6a4YY when i get my other camera back i will post a pic of the inside with battery
I am sorry but the charger port that is linked tot he USB port?
Not sure what you mean. Can you please clarify?
please forgive the neebie question what you are trying to do....what is the purpose.

As the link in my original post says basically i want a wireless charging system called inductive charging.
Something similiar to this too that i found on the forum:
http://forum.xda-developers.com/showpost.php?p=26443496&postcount=34
I want to take the wireless charger of a palm pre and modify it to work with my S2.
I need to take the charging coil and preferably solder it to the point on the S2 board where the charging takes place though the USB plug.
The guy in second link basically linked it to the battery contacts, i am not sure how safe that is since it bypasses most of the resistors and charging components of the board.
So hoping someone can help point out where i can do the positive and negative charging contact points on the board.
Awesome! found what i needed here. Will post when i do my similar mod.

OK, after getting my One for Xmas and a little extra coin to spend, I am going to attempt to add on wireless charging.
Due to the nature of my work, I need a case to be on the phone. I destroyed two Thunderbolts before I finally corrected my rectal-cranial inversion and put it in a case. So I ordered up a UAG case for my One. After some research, I stumbled upon a little gem on ebay, a QI charging receiver with a microUSB connector. I figured for $8.50, why not? I will not be putting the pad inside of the battery door, but between the phone and the case. I also ordered up a no-name QI charging pad.
I will update the thread when everything comes in and let you know how well (or poorly) the whole scheme works. I know I am losing my ability to plug into the USB port, but I can use a Samba app to transfer files if need be. Also of note, I don't use NFC, so I will never know whether it affects NFC's ability to read.
If anybody has any questions or feedback, please let me know. What I'm hoping to do with this little project is add some functionality to an already amazing device without causing any cosmetic harm or irreversible alterations to a sexy design I will hate to hide in a case.

Whoops, I must have missed your post. Guess I'm not as innovative as I had previously thought.
I know it's lazy, but thoughts? It's 1000 mA
I've never had wireless charging before and always told myself that my next phone would have wireless charging...

That one I believe is rated as 500mA so it's going to take a long time to charge. A 750mA one is better, but it will be thicker as well and the microUSB on them are shoddy. I would like it if someone knows the exact location of the +5V and Ground solder point on the mother board, that would be the best solution.
http://www.amazon.com/Universal-Wir...TF8&colid=3OC2TRSSGA72P&coliid=I1NLS41WJ2XY3W
This one looks like the same thing. Both say "Charging current: DC 5V/500mA-1000mA" but I wouldn't expect anything over 500mA. I ordered one anyway even though my case won't be here for another week.
interesting, if it is possible to "install" it under the back cover.!?
I wonder how long the OnePlus One will take at 500mA. I ordered the same one with "500-1000". Waiting on my case to arrive so I can actually use it.

I was going to make a thread today on this but I can confirm that most of these are actually 500mA regardless of what it says in the description. I already received the case I ordered from Amazon so I put it all together yesterday and it all plays nicely. You obviously loose the usb port but that's why I did all my rooting and unlocking first. It's plastic so it will likely not damage the usb port on the phone. I have not tested the charge time, will try today and let everyone know.
Originally I was thinking of putting the receiver behind the actual phone backing. Decided against it because you never know if you need the usb port. Also, I hate the feel of the back of the phone and much prefer the case.
If someone can identify the pins to make a direct connection, that would be great but for now it works!

Read my thread here about how I soldered on internally. http://forum.xda-developers.com/oneplus-one/general/internal-wireless-charging-t2819398
The one that I purchased was rebranded as 750mA, but on the original sticker under the one put over it it says it's rated for 1000mA. I have a couple of the black ones OP is talking about and they don't provide enough juice to even reliably charge the one. Check out my thread above and the link to my original post on the opo forum. I have a link to the one I purchased on ebay there that worked the best for me.
@inaudible101 - what tools did you use to remove the back cover?
At 500mA, it should take about 6 hours to charge a battery at around 5%. This assumes that you are getting the full 500mA, too, not less.

Yeah I tried a 500mA one and it just didn't cut it. The 1000mA one works much better. I may hook it up to my multimeter just to see what the real output is for my own sake. I used a pocket knife to get the corner up and then slid my thumb nail under and the hooks pop off easily. They have a video on their website showing that you can push on the back with your thumb and then just pry the bottom but I'm not sure how well that works.
Guys, what receiver do you have and how much does it really output? On mine it says 500 mAh but in reality it only has an average of 300 mAh. I measured this with Battery Monitor Widget.
This is my receiver: http://www.aliexpress.com/item/Univ...less-Charging-Receiver-Module/1973302276.html
Has anyone found a 1000ma version?
Is it safe to leave the receiver plugged in even if i'm not charging it, like would it damage my usb port?
Cause I just ordered one for my OPO and a wireless charger from aliexpress.
I just ordered my OnePlus One and pretty happy. I'll miss the wireless charging however, and I've seen these in the past, but think you could put this under the backplate? They seem pretty thin.

Opinion, or has anyone tried this?? Thanks in advance!
I'm thinking the same thing too. It should fit inside the back cover but I don't know if the nfc pad will interfere the charging. Haven't try wireless charging XD. Another choice is to put that pad under slim back case, should be OK and you don't have to open the 1+1 back cover too. One thing that I concern is the charging rate. With Qi charger, it's going to take forever to fully charge the 1+1. 2A charger vs 500 mA qi charger

First, search the forums on both on XDA and OnePlus.Net. Already ongoing discussions. That said, I've used a few models, including the one listed here. They charge S-L-O-W. Less than 10 percent per hour. If you do use this, get the model with the long end of the USB connecor facing up towards the screen and the narrow end facing down toward the back.
Please read the other threads before proceeding

The biggest problem you will have is with the USB plug part. Look at my post history and you will find my thread where I installed on internally. I'm using a 750mA one that seems to charge just fine. It's not as fast as the cord, but it keeps my phone charged all day. I have wireless chargers everywhere though.

You have to peal up the NFC antenna or it does not work reliably. There is a nice large thread I made in general that you need to read. You question has been answered very thoroughly with testing.

The one mentioned in all the posts (the red one) is no longer available in our USB configuration due to QA issues)
Was looking for this, thanks!
So I'm looking into the possibility of making a wireless charging solution on my own. I have lots of wireless chargers at home, work, in the car, and I would really benefit from getting wireless charging working.
I took a USB Qi charging coil and soldered wires, which I then attached (well, just touched ) to either end of the magnetic connector, and it worked.
The difficulty I'm facing is, how can I keep these wires touching the magnetic charging port semi-permanently without doing anything dangerous like attempting to solder it directly.
So I'm wondering if anyone has any neat ideas of how I might rig this up. Any ideas would help a lot! If I come up with something good, I'll make a guide so others can do it.
You could try to get someone to 3D print a side piece similar to the one on the Z3 wireless charging case from sony: http://www.sonymobile.com/us/products/accessories/wireless-charging-cover-wcr14/
Have them leave chambers to run the wire through.

I've been thinking about making my own wireless charging case similar to the sony branded case but using high quality leather, and an oem qi charging circuit with a 3d printed base clip with the circuit connectors integrated into the clip, just to ensure constant connectivity.
just looking into prices for scrap leather now.

Have you tried tape? It would be covered up by your case anyway, right?

I've thought of tape but I've yet to figure out a way to tape it where it will definitely stay in place.
I might be able to get a case that would cover it, but my current cases have holes so that magnetic chargers could be plugged in.
I've decided to try using copper tape to connect a Qi coil to the magnetic dock port. I'll see how it goes. Hopefully it will be as easy as I'm hoping it will be.
So I finally managed to make it work. Unfortunately, I had to solder.
I gave up with trying to line things up just right and keep it in place, so I just soldered a Qi receiver to the magnetic charging port, wrapped it around to the back of the phone, and fit in a case. It charges wirelessly now, so I'm happy. Unfortunately, I don't know if I'll ever be able to clean it up in the future if I want to sell the phone. But to me, wireless charging was super important. I was also able to continue using my Z1C battery case which uses the magnetic port, so I'm pretty happy with the end result.
Pics?
it's ugly, but I'll put up pics when I get a chance.
Pictures as promised. I had been concerned adding this might block NFC, but NFC works just fine. Obviously, magnetic charging cables don't work (but a Z1C charging case I have does.)
It adds some thickness behind it so the case doesn't fit quite perfectly, but well enough to stay on. I didn't have thinner cables, but having some might have been able to decrease the thickness. Also, I'm not necessarily good at soldering, so I just did what I could.
But I can charge it on my bedside table and in my iOttie Qi dock in my car, so I'm cool with it.
hmm not pretty, but i guess it works. how is the charging speed?
you should be able to clean it up fine if you use some solder wick.
Awesome job!
Can you please give us a link for the receiver?
All I can find are with usb
ugly doesn't even start describing it... seriously, you ruined that phone. You could've cannibalized a 3rd party docking station instead
duraaraa,
Thanks for blazing this trail for us, mighty brave to solder to your phone like that! Now that you've had this set up for a few weeks, is it holding up ok? I'd just about give my left nut for an actual phone case that simply has a wireless receiver built in and taps into the magnetic charger pins, but I doubt anyone will ever make one since (I believe) the Z3C is discontinued. I mean, they make those giant external battery packs for the Z3C that use the pins, so why not a qi-compatible one??? Anyway, no way I'm soldering to my pins so I'm basically trying to mold a connector out of epoxy that I can squeeze between the side of the case and the pins. (Basically I pushed one of my magnetic cable connectors into a clay bar and filled w/epoxy.) It's still drying so I have no idea if it's feasible at all, but wanted to pop in and say thanks for the inspiration.

Not good I'm afraid my friend... My first attempt (trying to mold a connector out of epoxy using a clay mold) failed, the thing came out looking like a chewed up piece of gum and just wouldn't work. My next attempt involved slicing up a couple of cheap magnetic adapters and cables to try to trim down the connectors to something reasonably sized, but they become really brittle when you cut them that thin... Unfortunately, I think it'd take someone with some type of plastic molding equipment or maybe a 3d printer (that is capable of making really small, fine-detail parts) to make this thing. I'm still disappointed that Sony makes a wireless case for the Z3, but not the Z3C, but I've also come to realize that the Z3C has such good battery life that maybe I don't really need such a case. (I come from a long line of Nexus, HTC, and Samsung devices so I've become somewhat of a charging addict!)
tl;dr: Just enjoy the Z3C and use the handy magnetic dock for overnight charging.
just looking at the magnetic connectors on the z3c I think there might be a way but it'll add a couple more mm to the height, would need to get someone with a 3d printer, but if the wallet is made of leather and is inserted underneath, with the qi wireless pad, and two wires made into connection terminals which would then clip onto the phone so a solid connection is made between those terminals.
Just to answer some questions, it's held up. I think it's fine -- anyone desperate for Qi should just bite the bullet and solder. Charging speed is similar to really any other Qi-charged device.

Sorry my response is so late!
It's the USB type. I un-soldered the USB ribbon and soldered a wire for the two connections.
So you would want to buy the USB version, I think.
Look into copper tape. I attempted this a little while back but I think my charging pad wasn't powerful enough. What charging pad are you using?
