solder points for inductive mod

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.
Thanks for your reply in advance.

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.

Acro S - Active Car Holder

I'm searching for an Active Car Holder (Cradle / Dock) for the ACRO S.
with the DK200 Charger Cradle Dock it is easy to Charge the Acro at home.
So do I stick the DK200 into the car. or there is a better possibility.

I would need exactly the same. Only problem is that the desktop cradle holds the phone vertically, but I need it on my dashboard horizontally. For watching TED, navigation, etc.
Options I found so far:
- buy another desktop cradle ($10 on ebay), cut it into two and modify it so the connectors come out from the bottom --> would be ugly I am afraid
- buy a cradle for another phone from KIDIGI , and try to push Acro S into that. For example Xperia S or HTC Incredible has very similar sizes, but I cannot test if it fits unless I buy one... and then I would need to hack it as well to put the connector pins to the bottom
I don't like either options... if anyone would have any other ideas, please let me know

Sorry for being out of topic, but for the cradle, do we just pull out the phone, cause it seems like I am going to break either one every time I do it.

I built my own active cradle ...
I bought a cheap hard case from ebay and I modified it so the phone will get in and out easy, then I glued on it some springs for the power connections and I also installed a micro-usb port so I can use any regular car charger with a micro-usb connector.
I also attached to it a suction cup with a multi-angle orientation leg.
I used epoxi resin to put everything together and the final device is extremely functional. I still have to build a case around the springs and micro-usb connector in order to have it "like from the factory".
I'll attach some photos tomorrow (currently the holder is in the car and outside is raining ... not to mention is midnight here )

yeah please please photos - can not sleep before

The photos, as promised
As I already said, is still work in progress (regarding the finishing of the case around the springs and the microusb port) but it is 100% functional.

VERY GREAT WORK :good:
From which Telephone is the cheap hard case?
Which Material are the springs?

This is the exact case I bought (but you can find even cheaper): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300795656907
As for the springs, those are from a battery holder. you can use even the spring from a mechanical pen.

Nice! Would like to mimic that.
I have a USB cable wih plug that I could glew to the back of a cradle, like you did. But what wires from the cable should be connected to the phone? And also, does anyone have any thoughts on the voltage and current that the Acro S expects on that connection? Regular USB values or a bit more?
Frank

Good
Very great work

I know the stock charger is 5v 1.5amp

Wireless Charging with Palm accessories [noSoldering/Soldering] + more info

I decided to post a new thread as most of them out there are for Galaxy Note II or Galaxy i9305
Before you start doing anything I'd suggest reading all these threads so you decide what's best for you.

thanks to "qianqinde" for showing how to remove the parts from the Palm cover.
http://youtu.be/0ga4N_Ih9GE?t=4m21s
The Parts I used:
1.Palm Touchstone Charging Dock-£4.99Amazon UK
2.Original Palm Touchstone Back Cover-£3.49Ebay UK
3.Soldering Iron + solder
4.Clear tape,because it's very thin. black electrical tape is thicker and want to make the slight bulge as smaller as possible. you will see on one of the pics i used electrical tape, but I removed it and used clear tape
5.Wires from old not Genuine iPad cable; because the wires are very thin.
Palm Pixi Cover-£3.99Ebay UK If you buy one of those,as far as I know positive and negative are not reversed (CHECK for yourselves before doing anything) as on Palm Pre cover!
Genuine Palm charger-£3.99Ebay UKI got this charger, because I needed a one anyway
Chargers I can confirm they work with the Palm charging dock: Galaxy S3(5v-1A)##Nexus 7 (2A)## old HTC Desire Charger (5v,1A)## If your phone keeps vibrating and the window that says charging keeps popping up over and over again, your charger is not supplying sufficient power. My Motorola charger(800mA) did that.
Good soldering skills are needed to perform the mod. I guess you wouldn't wanna melt the plastic on the phone so practice before you attempt this. Twist the wires to the desired shape first and then solder. This way you will prevent breaking off the pins from the motherboard
When you see the pics, you will notice I barery used any solder, this is, because you really don't need much as it catches really easy. It should't be a problem since there are no moving parts there to force the wires to fell off.
Decided to stick everything to the battery,because I rarely remove it.
You will notice on the pics I've put the wires along the of the battery as there is enough space for them to go in nicely
When you solder avoid pulling the wires too much so you dont damage the pins on the Phone's motherboard.
Put a piece of card board on the battery when you solder so you don't damage it.
If you have very thin wires don't hold the soldering iron for too long because you will melt the insulation around the wire. you could blow a few time so it cools down faster.

Making my own wireless charging case

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?

wireless charging solution thread

As we all know, the new Zenfone 2 is missing wireless charging capabilities, however there are multiple solutions to enable wireless charging on basically any phone.
Example is http://www.amazon.com/BEZALEL®-Wire..._1_4?s=wireless&ie=UTF8&qid=1432149451&sr=1-4
It is a cover with a Qi receiver built in, which connects to the charging port and it also provides an independent micro usb port as a part of the case.
The absence of wireless charging in Zenfone 2 is a deal breaker for me ( don't judge) and as soon as an appropriate case is available, I'll get it and the phone as well.
Please post your findings here.

Would love to use wireless charging but using a cover like the one posted is out of question.
I love the slim form and feel of this phone. so i will have to live without QI and other solutions.

This will occupy the mUSB port but would probably be the best current solution.

That's pretty cool. I like wireless charging because I'd rather not wear out my micro usb...but that setup kinda marries you to wireless charging all the time. I'd have to rig up wireless charging in the car and at work...not just at home. You use something like that?

Not sure if I'm going to stick with the ZF2, so I haven't gone out and done all that yet but qi adapters are pretty cheap now for both home and car. How effective some of the car ones are though are another story. iOttie has two models out now that look promising for the car.
There may also be the possibility of placing those adapters into a separate case just meant for wireless charging... remove the case if you need the mUSB port.]
Or... if they do release new back covers... get one that you install the qi adapter in and then one that you won't have the qi adapter in.

Why did Asus decide not to include the qi pins in the back ((((((((((((((((((((((((((((((((((((((((((((
>_<
what to do :'(

Here's a teardown: http://www.myfixguide.com/manual/asus-zenfone-2-teardown/
You could solder the DigiYes posted earlier (http://www.amazon.com/gp/product/B00HI8JYFE) onto the usb board. Or you could probably just jam the wires into the connector for a non-permanent solution. The pictures of the DigiYes are a little conflicting, but if it does have leads for the data pins, you'd be best off omitting them (you'll be limited to 500ma qi charging).
This is of course assuming there's enough space to wedge the DigiYes between the back cover and phone.

Which goes back to my point. Why did Asus purposdely omit to include QI/wireless charging pins on the back? It would had cost them hardly anything extra at all, and users could just have changed back cover to get wireless charging...

That one http://www.amazon.com/BLUBOON-Unive...2630&sr=8-2&keywords=qi+wireless+charger+1000 is 1000mA, if it does make a difference. But a case integrated receiver would be much better solution, if ever.

I bought that model. I have a Qi charger (used with a Nexus 5) hooked up to a 2A USB Adapter, and it barely charges the Zenfone. I do not recommend. Maybe a 2A receiver would work better.

It's ridiculous.... why did asus decide not to offer a wireless charging solution similar to the previous samsung galaxies/lg.
Have the pins for charging on the back, and let the user change the case to a qi receiver case or add a qi receiver pad inside. this is honestly the only thing that disappoints on this phone (((((((((((((

I just received mine and there is enough space in the back cover for the receiver to fit in, albeit with a small bulge. It does show my phone as charging even when just held up to my Moto 360 cradle; whether or not it's charging, however, I have no idea.

Thanks for trying. Did you actually solder or just plug it in the usb port? If you plugged it in the usb port, does the cover close without damaging the cable?
I'm asking because if that works, we could potentially design a slightly thicker but hollow back case that could hold NFC and the wireless receive without unnatural bulges.

Yeah I judge, wireless charging its just another feature. A small battery, a slow processor or low memory now that's a real deal-breaker since your phone wont last a day, apps will run like hell and you will always have to micromanage just for things to run properly.
I'm way more pissed off at this phone not having a removable battery, not just because its a real deal-breaker during travel where I will be forced to lug around one of those brickish power banks but because Li-ION batteries have the lifespan of a mosquito. I already had 2 phones like that and the result was always a massive pain in the ass to deal with.
I rather buy a case with an extra battery than this thing

Three pins USB Board?
Hi there
Maybe some one knows, what are those three pins on the USB board, that are accessible without disassembly phone?? That should be connectors to charging instead of usb socket?

I have a qi charger built into my car. I do not like aftermarket charger added to the phone. So this is a deal breaker for me and will not consider any phones without buildin qi charger.

Looking to buy this phone and own a quick charging card like this. Is it possible to slip the card under the back cover (without a case) or will it cause it to bulge in too unsightly a manner?

It can but causes a gap near the usb port that I could not close. I would've run it inside if it didn't do that.
