yes he did, i'm gonna try it with just tape - his solder blobs seems to be huge and because of the the cover makes this bulge... maybe then it will fit perfectly :)

the samsung wireless charger looks nice but i like the idea with the magnets of the touchstone!
[Galaxy S III Accessories] stu5797:
please post pictures and a possible video. This is so interesting!
[Galaxy S III Accessories] N23:
i'll do as soon i get the touchstone kit and have some spare time to do this (hopefully on sunday...)

what happens when you place an induction charging compatible device on an induction cooking range? Will it charge the battery, or will it overload the circuitry and destroy the phone\battery?
[Galaxy S III Accessories] Zabalba:
I wonder what happens when you plug in the phone with usb while it's inductively charging.
[Galaxy S III Accessories] mdcarter67:
I would think they would work together or one would be disabled by the other. Don't think they would allow both if it could cause damage.
[Galaxy S III Accessories] stu5797:
There is no way. I begged for it in my videos. I guarantee that in september there will be a way.

This looks great. Which works best, the Palm pre or Palm pixi back? It seems like the pixi might be a bit smaller and create less of a bulge, but are the magnets strong enough to hold the the S3 on the Touchstone. I see people are using both. Thanks for any guidance.
[Galaxy S III Accessories] fylim:
I am using pixi. Cover closes tightly and there is still a small noticeable bulge. Phone won't lie flat perfectly. Without any case on 4 magnets are strong enough. With a tpu skin, 8 also don't feel much magnetism.

I just wanted to make sure I was getting the right parts for this mod as i would really like to try it. If someone could please link the pixi back and the touchstone that would be great.

Thanks in advance just dont want to order the wrong back.
[Galaxy S III Accessories] pwned101:
I'm definitelt getting one when it comes out..
[Galaxy S III Accessories] pkoper:
It seems that my battery is draining faster with the coil installed. I loose like 30% over night. Don't think it was that much without it.

Going to take it out for a few days.
[Galaxy S III Accessories] imranb_001:
Whats the max range of wireless charging. Or should ut be always placed on the mat for charging. I want flexibility like while charging with wired.
[Galaxy S III Accessories] pkoper:
It's around 3 to 4 mm, works with a backcover for me.
[Galaxy S III Accessories] neo6776:
You wont get flexibility. It sits on the mat and cant be moved.

Wireless charging is in its infancy so will be a good while yet until you can move about with it!!
[Galaxy S III Accessories] jcolt:
Thanks for everyones help on this thread. Did my mod today and worked perfect. I used the Palm Pixi back with the 4 magnets (I dont use a case on the phone).

My steps were:

1) remove the coil and magnets from the back of the Palm Pixi

2) align them on the touchstone (unplugged) and put the sticky back on the coil and magnets

3) Using copper tape, I mapped the tape to match the wireless charging prongs on the S3

4) soldered the tap to the pixi ends

5) put a dab of solder on the copper tape to ensure better connection to the S3 - NOTE I did not solder the copper tape to the S3!!!! - I just put it on the copper tape to create a little bulg to reach the S3 pins.

6) tapped the pixi back into my S3 back

7)put the door back on the S3 and placed it on the touchstone - wirelss charging! No real buldge to speak off.

One question - i would like to test to see how much charge i am getting from the touchstone. Can anyone advise on an app which will tell me the charging rate?
[Galaxy S III Accessories] pkoper:
You could use current widget. I get 466 mAh from the touchstone.
[Galaxy S III Accessories] fylim:
Folks,

Any idea how to trigger S3 to enable dock mode upon wireless charging ?

Thanks.
[Galaxy S III Accessories] ericlmccormick:
You could use tasker or locale to trigger desktop mode when charging. It won't know the difference though between that and normal charging/sync
[Galaxy S III Accessories] fylim:
I guessed as much. Thanks for confirming
[Galaxy S III Accessories] }{Alienz}{:
1. Stick an NFC tag on the Touchstone.

2. Program Tasker

3. Profit.
[Galaxy S III Accessories] thardie:
I tried the powermat coil out of the HTC EVO 4G powermat back. Under no load, putting it on the powermat gives 5V and the little chime. Connecting it to the 2 pins next to the battery gives no chime, and no reaction from the phone. Connecting it to the USB gives chime and charging like I connected a USB charger.

The only conclusion I can reach is the receiver for the EVO 4G cannot deliver enough current for the wireless charging input on the S-III.

I'll try soon with a normal powermat receiver...
[Galaxy S III Accessories] Lpuboy87:
sums up the process easily :highfive:
[Galaxy S III Accessories] SJUnion:
Great work guys. That being said I wanted to share this. Not as cheap or as functional as the Palm hack but if your worried about taking things into your own hands and have a vzw S3.

[Galaxy S III Accessories] Araltd:
I'm doing another wireless mod to a larger extended battery cover+battery. This time I bought a Pixi back, instead of a Pre back, and so far I think it was MUCH easier and better looking with the PRE back. The pixi back doesn't magnetically attach as well as the pre back did... and I don't see any difference in thin/thickness between the 2 copper coil units (pre vs pixi).

Just posting more as an fyi. I think the pre back requires a lot less tinkering.

I will ask one question, where are you guys finding copper tape? I looked everywhere today with no luck. I've found it online, but not in any store where I could actually walk in and buy some.
[Galaxy S III Accessories] fylim:
I noticed using charge widget to measure temp, charging using the induction method is much warmer using pixi cover. 43 degrees c (0.466amp) vs only 38 degrees using AC charger (1.2amp).

Anyone experience this? Any diff using pre cover?
[Galaxy S III Accessories] Mherder:
I accidentally ordered the Pixi back... will it still work? I have the dock and back here but haven't started anything.
[Galaxy S III Accessories] stu5797:
You ordered the correct one. The pixi one is thinner and much easier to install. I guess thats opinion though.

Also, I wonder if the verizon back would work with a palm touchstone charging base. I just saw a bunch of those at a salvage yard.
[Galaxy S III Accessories] SJUnion:
I don't think the Verizon S3 inductive cover will work on a Touchstone. I tried it with my Rezound that had a Verizon inductive back and it did not work. From my understanding Verizon's charging system is based on a different standard.
[Galaxy S III Accessories] Araltd:
I personally don't think that's true... They seem about the same "thickness" to me, and I will say the larger electrical contact pads on the PRE back are must easier to solder to. But as stated above, thats simply MY opinion ;)

I think the bulge is from the wire I used, if I could have used copper tape, that would probably have eliminated most (or at least more) of the bulge ---- which is minimal even with wires from a usb cord which is what I used.
[Galaxy S III Accessories] flashcity90:
Didnt notice this thread till after i created mine lol but i moded my defender with the verizon cover to work with the wireless charger. check it out

http://xdaforums.com/showthread.php?t=1820831

Oh and to the person above me. the verizon cover doesnt work with the touchstone. I believe i read somewhere that the pre used inductive charging and this is a different system. Not sure though so take that with a grain of salt.
[Galaxy S III Accessories] Michael_P:
Can someone tell me the input voltage the 2 wireless charging pins use? is it 5v USB or direct 4.2v battery power.
[Galaxy S III Accessories] kench33:
Just a question, which are the positive and negative contacts on the pixi back?
[Galaxy S III Accessories] cweemin:
Is the back cover for sprint version thinner?
[Galaxy S III Accessories] Araltd:
Check with a meter... BE SAFE.
[Galaxy S III Accessories] fylim:
If you are using international s3, when pixi is stuck to cover, upper pin on pixi matches upper chargin pin of phone. Lower pin on pixi matches lower charging pin on phone.

If you want a pic check back a few pages or just search for pixi.

I also modded my S3 with a wireless charging mod but used a different back cover.

I hate the default back cover on the phone so I purchased this one:

http://www.ebay.com/itm/221070072960?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Here's how to use it for the mod:

1. Grind down on the plastic on the lower part of it (inside of course). I think it took me roughly 10 minutes of grinding until I felt the plastic was thinner at the bottom. This allows the inductive circuit to go in without creating a big bulge in the cover.

2. Purchase a few neodymium magnets. I believe I ordered 9 magnets with 9mm by 1mm. I used this place: https://www.supermagnetman.net/index.php

Delivery was roughly 1 week. This is so that the phone locks tighter than the original magnets included in the touchstone covers. Use 4 of them and tape or superglue them where the original magnets would go on the cover. Note, you CAN use the original magnets but the phone won't hold well with the new cover.

3. Install the Palm Pre inductive charging circuit as specified on this topic. I used very thin wires and directly soldered mine to the pins on the phone. I then taped it the back cover. The tape allows me to move it or remove it easily.

This works and looks great. I have two questions for you guys though.

1. Has ANYONE found a way to remove the annoying "Wireless charging" notification or the sound it makes?

2. Has anyone tested to see if using a 2amp charger doubles the charge rate? The Palm Pre/Pixi Touchstone specifies a minimum of 1amp charger. Anyone measured a difference in charge if a 2amp charger is used?
[Galaxy S III Accessories] stu5797:
I like the sound when connecting to the charger but you can delete Charger_connection.ogg in system/media/audio/Ui. I am still waiting for someone to get rid of the popup when connecting to the charger. As I said in the video i think we have to wait til september when samsung releases the official wireless charging kit
[Galaxy S III Accessories] WinDroidGuy:
I might have missed it in the 23 pages...here is what I came up with for my "setup" Verizon S3 Inductive Cover only downside is that I can't have a case, because the door is too big :(

I was searching around and I found the Palm Inductive covers for $4, so I figured I'd buy one and mod it like this thread has done and be done with it. But I have a few S3 devices and a mat for multiple devices at once, I don't want to use the normal Palm Charger to charge one device at a time. Has anyone used the "mod" with a non palm charger? If so, I am going to return my Inductive Covers and just do this mod and I'll be able to use cases again :D
[Galaxy S III Accessories] }{Alienz}{:
It will NOT work with a non-palm Touchstone/inductive charger.

The reason is that the circuitry in the back cover and the charger "pair" when you place the device on the Touchstone in order to begin charging. Nothing will happen if you use a different charger because the pairing won't work and the the back-cover circuit will refuse all charging.
[Galaxy S III Accessories] electech13:
Okay I obviously was severely misinformed and completely misunderstood what this whole NFC capability on the S3 was for and how it worked or what was needed.

I really thought that with NFC on the phone and NFC BATTERY in the phone, I would simply need a charging pad, turn on NFC, place on pad and away I go! I was obviously mistaken? And apparently nieve.

So if I understand correctly, one needs some sort of charging case, cover or sleeve FIRST and then the charging pad? Or some sort of mod like posted here to attach to contacts within phone?

If this is the case can someone explain this whole built in NFC capability? Because if I can take ANY phone that DOESNT have NFC and buy the charging pad and associated sleeve ans turn it into a wireless charging device, then what is the purpose or point of NFC built into S3 to begin with if I have to do all those steps anyways?

I'm rather confused on this.

Thanks
[Galaxy S III Accessories] N23:
NFC - Near Field Communication

NFC is used for communication and not charging!

Wireless charging is a completely different technology - you can equip (nearly) every phone with wireless charging capabilities with some modding or a case.

the difference of the S3 is that it has to pads prepared so you just have to switch the backcover (when the official wireless charging set is on the market) to get the wireless charging working.

but through these two pads it's very easy to add a custom wireless charging coil and not have to wait for the official one!
[Galaxy S III Accessories] }{Alienz}{:
Can anyone measure charging rate of the Touchstone when using 1amp vs 2amp charger?
[Galaxy S III Accessories] fylim:
Use current widget from play store. No diff for me 466mah charge rate. Using Pixi cover circuit.
[Galaxy S III Accessories] eatonjb:
The question is, anyone with the Palm mod, does the NFC Work with that set up.

== Yea.. I tapped that!
[Galaxy S III Accessories] N23:

[Galaxy S III Accessories] syer1:
How are you getting current widget to display the charge rate? Mine always stays at 0 mah. It's driving me crazy.
[Galaxy S III Accessories] fylim:
It should show the current after a sec or 2 with default settings. Tapping the widget change updates the info.
[Galaxy S III Accessories] stu5797:
Mine doesn't show current either
[Galaxy S III Accessories] syer1:
Nope, mine does nothing. I tried it when i was running blazers Rom and on cm10 and neither seem to work.

Got this mod working with the pixi cover. I used earphone wires as someone had mentioned before. They are soldered on wireless receiver end, and the other ends I soldered to some bent paperclips that I stuck in the phone pins (to not solder and ruin the phone contacts). I taped it to my back cover which was the samsung flip cover. It was a tight squeeze but it works!

---------- Post added at 02:39 PM ---------- Previous post was at 02:30 PM ----------

It works for me but I had to set the touchstone receiver towards the bottom of the back cover. It seemed to interfere with nfc when I had it placed right on top of the battery.
[Galaxy S III Accessories] williamn:
I had already done this with the old Droid Charge, but didn't like having wires attached from the phone to the battery back since it made pulling the battery very annoying.

I ordered some copper tape as some have done on this thread and chiseled out space in a new battery case so the metal pieces and coil would drop into a recess. To finish it off, I simply taped it down. The phone secures on the touchstone dock very well because there's less plastic in between and more importantly, there is no bulge in the back.
[Galaxy S III Accessories] sifihog:
Bulge

I've found that if you flip the Pre "sticker" 180º (the coil would be near the bottom of the phone and the circuit board would be near the battery), the bulge shrinks a lot.
[Galaxy S III Accessories] Fallon:
After not seeing expected readings with my first Touchstone & Pixi guts, I got a 2nd set with the OEM Palm transformer & micro USB cable. My 2nd set is still only showing about half a volt when I hit the contacts with my multimeter. Is this correct for a no load reading, or am I missing something?

I had assumed I broke something gutting the old Pixi case, but the same readings on my new not yet gutted case and a new Touchstone has me wondering.
[Galaxy S III Accessories] }{Alienz}{:
Anyone experience this behavior?

When battery gets to 100%, if the phone remains on the charger it will periodically (as often as every 2 seconds or 30 seconds) dysplay the start charging sound and notification as if it was just put on the charger. This happens ONLY when it is fully charged at 100% and sitting on the charger.

Anyone know how to get rid of this?
[Galaxy S III Accessories] knuckelpuc:
I'm looking to do this, but I'm considering trying to replace the magnets with stronger ones. Does anyone know of a place to get stronger magnets that are the same size as the existing ones?

My goal is to mount a puck in my car, and then just stick my phone to it as a dock and to charge, but I want to make sure that my phone is on there extremely well, especially if I hit a nice bump in the road. Has anyone had success doing this with the S3? And do the stronger magnets cause any issues with the compass?

Thanks guys!
[Galaxy S III Accessories] syer1:
Yea i have mine mounted on my dash. Works pretty well. So far the phone hasn't fallen off yet. Only thing i don't like is the charging rate. If i have navigation on it drains the battery still. I put four stronger magnets on my sgs3 and four on the touchstone.

Replace xx with tt since i can't post outside links.
[Galaxy S III Accessories] WinDroidGuy:
I was planning on doing this as well...just got my touchstone/door setup done, need to find stronger magnets.

I have done something similar to do, I may put a small piece of thin metal behind the charger and glue it down...then replace the touchstone magnets to see if it holds down better :)
[Galaxy S III Accessories] syer1:
you dont have to replace the touchstone magnets. i already tried that route and its not worth the time. just add 4 stronger magnets on the top of the touchstone and four on the sgs3's battery cover. Ive gone over bumps and have hit turns pretty fast and besides a little slide, my phone stays still. Im also rocking a metal bumper and even with the added weight, the phone still stays.

Can anyone please confirm that the palm pixi charging back also has the positives and negatives reversed like the PRE? JJust got the back deliverred today and I want to to a proof of concept to check that its actually charging. I will use some wires from an old headphone as seen on some videos and posts on this thread, but I just want to make sure I connect the wires in the right way. Just need confirmation about the pixi back

Thanks
[Galaxy S III Accessories] syer1:
On the pixie, the top is positive and bottom negative.
[Galaxy S III Accessories] eatonjb:
I have a question or a few actualy.

1. Does this one stop NFC from working. right now I was able to pacure a Verizon back but since my AT&T phone does not have the 4 connectors, only 2. the NFC antenna on the backing on the cover is blocked by the wireless coil, and the NFC that is a part of it, does not connect to anything.. :(

2. has anyone tried installing on the bottom of the phone part where your NFC antenna is not and tried NFC.

3. does the Pixi charger work with the "Qi" or something standard? or is it the touchstone only?
[Galaxy S III Accessories] alitech:
Perfect advice. Proof of concept successful. Thanks a lot mate.

Now another question, what is the best charger to use for the touchstone charger? I just plugged in the samsung charger micro usb charging cable into the touchstone and it worked, however, I just want to know if that is the best one or should I buy the official PALM charger and cable for this?

Will any charger do? Is there a charger out there that would push the charging up to nearer the 1000 MAH mark from the 450 MAH? I dont have a multimeter and I dont know how to use one either.

THanks
[Galaxy S III Accessories] VittoCornelius:
Hey guys I did this mod couple of days ago and everything is working fine. Went with the upside down method for pre back to minimize the "bulge". Soldered to pre back using the thinnest wire I found at radio shack (couldn't find copper tape anywhere and i didn't want to wait for one of off ebay, if you look at the pins on SGS3 you can see the _/\ shape. I was able to thread thru the thin wire thru that small loop finishing the mod without the need to solder anything on the phone. But enough of the boring story. I just have one question :). I noticed that when the phone hits 100% the charging stops as it should. But the screen stays on at all time. Not really a big problem but kinda bothers me that it stays on while I'm asleep ( I'll start charging it before bed and its fully charged in maybe 2 hours damn fast thing lol). So the question is can the screen on be disabled somehow? So that maybe just the charging LED turns off? Please let me know ;) thx in advance!
