When I get home, I will have a look at the speaker cable but i'm not entirely sure, and for the solder I don't think the guage matters as you are only soldering on the charging circuit pins and creating a solder ball on the end of the wires. For the actual wires I recommend stripping the insulation off completly and then replacing it with heat shrink as this creates a thin layer of insulation.

Yes the back cover fits perfectly, you can not feel the coil or the charging circuit but you can feel a slight bump where the wires go but its not noticeable. Its quite a nice fit and handy as the Palm Pre modules lines up perfectly for polarity, you may even get away with having the circuit with the pins directly lined up to the note charging ports to prevent feeling the wires and just extend the coil itself.
[Galaxy Note II Android Development] FloatingFatMan:
What does it look like actually ON the Touchstone? It it stable?
[Galaxy Note II Android Development] rj3005:
Your speaker wires are really thick I would use 0.7mm lacquered copper wire
[Galaxy Note II Android Development] Ryan_G:
I will post a picture of it when I get home, but it is quite stable on the touchstone it holds it up. It will come off the magnetic field if you physically knock it off but it wouldn't come off if you knocked the table or anything its on.

I think the speaker cable I used was about 1mm thick i will double check but 0.7mm would be best, but with a 1mm you hardly notice it on the case anyways.
[Galaxy Note II Android Development] RavenY2K3:
Great mod, it's pretty cool how android has picked up the wireless charge, I didn't even know it was natively supported. What is the charging time like compared to a normal tethered charge?
[Galaxy Note II Android Development] nm8:
wow nice and cheap... what's the voltage coming out from the coil ?
[Galaxy Note II Android Development] Bond@007:
It will take around 6-7hrs to full charge. Not great ... :(
[Galaxy Note II Android Development] Ryan_G:
I measured 5.6V from the output, but I didn't measure the actual coil itself.
[Galaxy Note II Android Development] Ryan_G:
I'm not so sure, it was something I quickly did before I went to work not had a play with it yet. I'm home now so I've docked it on the charger at 50% so I will report back in hour with what percentage it is at.
[Galaxy Note II Android Development] nm8:
Thanks for hte quick reply.

I have 2 concerns:

1. will 5.6v fry the battery sooner ? (forgot to ask the ouput amperage)

2. if the back cover bulges, it might crack the cover sooner or later..

what do you think ?

thanks
[Galaxy Note II Android Development] Ryan_G:
When I measured the output i didn't have a load on it, so I would expect a slight drop in the output voltage. I will measure the amps tomorrow, to see what its drawing I will plug it in to the Samsung 2A charger but i got a feeling its limited to what it can draw. I couldn't comment on whether it will fry the battery sooner but I will also measure the voltage to see if there is a drop.

The back cover has minimum bulge, hardly noticeable. You can always use thinner wire if your worried about the bulge like 'rj3005' mentioned about using 0.7mm. I highly doubt the cover would crack as its quite flexible in itself.
[Galaxy Note II Android Development] nm8:
Can I just clarify one thing, do you mean the buldge is caused by the x2 cables that you soldered to the terminals and not the actual big circular coil (sorry don't know what its called). cheers
[Galaxy Note II Android Development] Ryan_G:
Yes the actual 'coil and charging circuit' doesn't bulge only the two cables you can slightly feel going from the charging circuit terminals to the galaxy note wireless charging ports.

Like I said the bulge is very minimal, nothing which concerns me but could be overcome my using thinner cable then what I used.
[Galaxy Note II Android Development] farfromovin:
I dont know why Tmo users assume its a software issue. I think its more likely a bastardized hardware issue, remember the Sprint version doesnt even have pins. I'm becoming a firm believer that the only way to do it on a SGH-T889 is to solder into the micro usb connector.
[Galaxy Note II Android Development] nm8:
I think that is true, as I have owned previous devices like Artemis 3300, and the Tmobile version didn't have the GPS hardware. That's what carriers do even in UK.
[Galaxy Note II Android Development] Ryan_G:
Its seem that the hardware is there for it, could somebody confirm whether they get a voltage out of the charging pins when you plug a charger in the phone. This will confirm whether the wireless charging pins is hard wired or whether it is disconnected.
[Galaxy Note II Android Development] flez1966:
Depends on your supplier, if you get a t-mobile phone from t-mobile they should be no difference than getting it from a independent store or a different carrier, I have never seen a carrier specific model in uk with HW missing, I have heard of models with a slight model number change etc or a carrier having a specific colour model.

I always try to get my new devices from carphone warehouse, as they dont stock carrier specific, and mostly stock unlocked handsets so they can just pull one of the shelf and give you the sim for your chosen carrier.

my note2 is such. supplied for tmob, just put my '3' sim in to use up my old prepaid allowance
[Galaxy Note II Android Development] FloatingFatMan:
US carriers do this, but UK carriers do not. Though network specific devices will usually be SIM locked, the don't vary the hardware at all from the unlocked versions.
[Galaxy Note II Android Development] flez1966:
But they do the software, and usally add without taking away.

And some networks will not be happy if you use another networks phone with them, the worse case of this happened to me some years ago, I had a phone on contract with vodaphone, a 3g sony ericsson, after my 18 month i left, and got a 1yr sim only deal with '3', at 11 months they phoned me and offered me a new phone and a 2yr contract, i declined and said i would happily stay with them on my current deal, and i'd be happy to stay for 2 more years, but no new phone please. I stood on this decision for two days and about 4 more sales calls... then they cut my phone off....

yes they did 'something' so my sim in my phone said no service, but my wifes sim in it worked, and my sim worked in her phone, but if the network saw my sim in my phone, no service.... they denied doing this, and said my phone was incompatible with the network.. needless to say I didnt pay any further bills and eventually owed them about 2 months + calls, and never paid them as my pound of flesh for ruining my happy days and making me get a new number..from 02
[Galaxy Note II Android Development] FloatingFatMan:
They have no way of knowing what device you're using on their network. Sounds more like there was just a **** up in the billing and they disabled your SIM. I was on a SIM only contract for several years with T-Mobile in the UK before I got my N2, using a variety of devices. No problems whatsoever.
[Galaxy Note II Android Development] flez1966:
No, you didnt read it right, the phone worked with other '3' sims on the '3' network(and did for many months, I just gave the wife my sim, and i had hers), the '3' sim worked in any other phone, but put _my_ sim in _my_ phone, no service... they kind of made them not like each other...and it was not an electrical failure, I could read data with the phone from the card and save new numbers to it etc, was just them saying take a deal or we chuck you off.
[Galaxy Note II Android Development] switt:
I gave up on the wireless charger for now (I'm on Tmobile) but if you look through my comments you'll see I tested just that and I was getting current. This may just be a software block. If you want to test, just make sure your battery is below 90% or whatever magic number Samsung uses to slow/stop charging.
[Galaxy Note II Android Development] garyd9:
That is an incorrect statement. The device will transmit it's IMEI to a tower when handshaking with the tower. That IMEI includes both the information required to identify the make/model of the phone (TAC), and a serial number of the phone.

This is used to ensure compatibility, to block stolen devices, etc.

http://en.wikipedia.org/wiki/International_Mobile_Equipment_Identity
[Galaxy Note II Android Development] FloatingFatMan:
Well yes, that's true, but what they do not do is use it to block devices bought from other networks; not in the UK at least.

That list is only used to block phones registered as stolen.
[Galaxy Note II Android Development] flez1966:
I still have ''the'' sim, and I still have 'the' phone in a draw upstairs where its sat since I could not get the replacement case on (chubby finger syndrome), I'm more than willing to stick it in a jiffy bag and send it over, as I have always kept it for nay sayers and because I had planned to try to change its imea from a dead phone and use it again, but instead I ended up just replacing it with a more modern phone

While I have to agree I have never seen it before, and never since, it struck me at the time as a 'big step' for them.

You will find what I say to be 100% truthful, nothing wrong with either phone or sim, but they stopped working together after I got a OTA sim update from '3' and have never worked together as a pair since. phone still works on '3' network, but not on the original sim

On a more on topic note, as I am not debating this further as its diluting the thread, how can i check if my n7100 will work with this, did i see a mention of a 5v being injected from a usb cable? as soon as i connect my coil to my phone it stops giving any voltage like its shorted out, I have checked the polarity and it matches the photos of the flexi pcb one just a page or so back.

It may be just the problems caused by lack of enough original silver foil, but my new palm back should arrive tomorrow.
[Galaxy Note II Android Development] WhyKlwd:
Wow! Awesome mod thank you very much! I have a Canadian i317m Note II.

The materials was ordered last Friday so I hope to get them during the week or next week. I'll post my results as a working mod should prove functionality for ATT/Rogers/Bell/Telus's Note IIs.

Thanks!
[Galaxy Note II Android Development] manudas:
Does somebody know if this mod would work with CyanogenMod 10 ?
[Galaxy Note II Android Development] stu5797:
I believe it works better because you don't get that horribly annoying iphonish popup everytime you put it on the charger.
[Galaxy Note II Android Development] manudas:
Thanks!! But I would like to know about some experience with this... Has someboy tried this for confirmation?
[Galaxy Note II Android Development] vinas1:
I'll check the voltage tonight to see if it's there (on the pins near the battery) when plugged in.
[Galaxy Note II Android Development] vinas1:
Okay, I just double checked for voltage on the T-Mobile pins near the battery door. Here's what I found:

With the charger unplugged, my FLUKE 87 is reading 0.000vdc

With the charger plugged in my FLUKE 87 reads 0.000vdc

My conclusion is that this is a dead/disconnected circuit. Upon further analysis I found that the GROUND is connected, but the positive terminal seems to be isolated. Bummer. No wonder why my wireless mod didn't work out. :mad:
[Galaxy Note II Android Development] nm8:
can you try connecting the negative terminal somewhere else?
[Galaxy Note II Android Development] flez1966:
I would not expect to see a voltage output from input pins...

I get nothing on mine. its a generic non branded unlocked handset

negative terminal reads zero ohms to the sim card slot metal
[Galaxy Note II Android Development] rickhuizinga:
I agree. Further, connecting power to the USB port should not affect the voltage on these pins. We already know that the phone can differentiate between wireless charging and USB charging due to the popup dialog that appears when you charge wirelessly. The USB +5V pin therefore is not directly connected to the wireless +5V input pin.
[Galaxy Note II Android Development] vinas1:
I hope you're right, because in that case perhaps there is a chance of these induction pins working... :confused: :good:
[Galaxy Note II Android Development] Ryan_G:
I got a voltage plugging the charger in and measuring the wireless charger pins, it was low but this is how I worked out the polarity before doing this mod. I got around 0.34V.
[Galaxy Note II Android Development] Ryan_G:
Sprint confirmed to have wireless charging contacts

Sprint Note II confirmed to have wireless charging contacts
[Galaxy Note II Android Development] vinas1:
I wonder if that has anything to do with the T-Mobile version... As in, I wonder if the paths to the wireless charging pins are actually in place or not. I might have to sacrifice my Note 2 in the name of science and find this out! :good: (I need to get my bravery up first though haha) :fingers-crossed:
[Galaxy Note II Android Development] nm8:
GO GO GO !!! You can do it!

Oh YES YOU CAN (former pres. Obama)!!!

PS.

Don't forget to take pictures
[Galaxy Note II Android Development] stu5797:
Please make a video!
[Galaxy Note II Android Development] Ryan_G:
Only one way to find out :good: if it helps from reading the discussion on some of the threads, taking the housing apart is a matter of some screws and it doesn't have any warranty stickers.

Good Luck
[Galaxy Note II Android Development] randy2:
Ok I have a theory based on why it's so slow other than the kernel although I hope someone else does the mod as I don't have the parts for this I think the charging slowness might be do to using the qi standard and not palm every mod to date uses palm and not qi if in theory both will charge a phone as long as u have the right male female components but qi standard might allow a faster charge someone. buy a old htc wc thunderbolt case Take it apart and adapt it to a qi charging station
[Galaxy Note II Android Development] nm8:
Actually, I like the slow charging on this mod. Slow charging is Healthy charging. If I want to charge quicker, I just plug in the usb charger.
[Galaxy Note II Android Development] flez1966:
No my touchstone base came without a supply, I just thought a micro usb from the pc would do, now I am not so sure as today I received my new pre back, sitting it on the stone I get no voltage unless I force the stone into charge by injecting 1v into tp6, so its no different than my receiver coil with damaged silver foil/tape, either I have a faulty stone, or I need genuine touchstone psu.

Can anyone confirm if a genuine touchstone psu is a requirement for error free operation?

I have ordered another stone, but it wont have a psu I guess.
[Galaxy Note II Android Development] nm8:
Nope, I use a HTC 5v 1amp charger with Nokia Micro USB cable witht the touchstone. See my pic in page 10 of this thread.
[Galaxy Note II Android Development] flez1966:
Thanks, in a few days the new stone may reveal what's wrong, it's so simple It can't fail... /famous words
[Galaxy Note II Android Development] Ryan_G:
My touchstone never came with the original charger, I use my samsung charger and that works perfectly and ive tried my htc charger and that work. Only one of my chargers didnt work with it and that was a dealextreme charger.
[Galaxy Note II Android Development] flez1966:
Thanks also, I know on my n700/fm6 that the original charger uses 2 grounds to signify 1amp and without it only 500ma on a data cable, got me wandering if it's similar, I'll dig out a few chargers and see if anything changes.
[Galaxy Note II Android Development] rickhuizinga:
0.34V indicates it is not directly connected to USB +5V. It does show that the pins are not disconnected from internal circuitry, and it is quite likely the T-Mobile firmware has disabled its ability to enable charging from these pins.
[Galaxy Note II Android Development] Ryan_G:
It must be leakage from the charging circuit, when I was measuring I wasnt expecting a voltage. Back feed from the charger, gave me an indication of the polarity.

I was hoping that if someone got a voltage from the pins with the tmobile note then its shows that it is connected to the main board.

http://xdaforums.com/showpost.php?p=33234960&postcount=49

The last part of the post shows that switt got 0.4v reading from the wireless charging pin on his Tmobile Note II
[Galaxy Note II Android Development] harpocrates:
Hi Guys, in order to test this without ordering anything, if you have access to a power supply you can set it to 5volts and connect the terminals using cabling or something. I tried this on my tmobile note and confirmed that the us tmobile does not see anything coming in. I suspect that this was not enabled in the software so I have a favor to ask from the international users who have succeeded with this mod.

Can you set logcat to be running prior to placing your phone on the palm charger, place it on charge..leave for a few seconds..just enough to see the wireless charging notification popup then remove phone and stop logcat. Please send me this logcat. I am going to ask a dev here ptmr3 who makes the jedi master tmobile galaxy note 2 rom to look into this to see if he can decipher if the software is enabling a feature which is disabled by default. I am not a dev so I doubt I can decipher this myself, but its the best i can think of since the pins are there but it wont see any incoming voltage. I am hoping there is something in the software which has disabled the hardware and its as simple as enabling this...

So please..anyone who has it working please send me a log following the above procedure. If you can tell me the exact time indicated on your phone when the wireless popup message ocured it may help.

Thank you and apologies if this has been mentioned but the thread is very long and despite trying to go through every post i might have missed this.
[Galaxy Note II Android Development] harpocrates:
its assumed its software because the pins are there and it could be similar to the original nook that was released that had the hardware for bluetooth but no bluetooth software...with a custom rom, bluetooth worked...

we cant say its not a software thing until we are sure....the sure way to do that is to take apart an international note 2 and a tmobile note 2 and compare the circuit to see why the charging pins are there and if they are disconnected..
[Galaxy Note II Android Development] dixonwa:
I think Note 2 US T-Mobile version might be missing some hardware. I checked the resistance between the two contacts and the circuit appears to be open. Someone may want to try this on a confirmed working version of the phone to see if it reads the same.
[Galaxy Note II Android Development] Ryan_G:
I got the same reading, for the international note.
[Galaxy Note II Android Development] flez1966:
Have you tried using diode test function between pins, one way I get nothing other way I see a reading that does away like there's some capacitance.
[Galaxy Note II Android Development] Ryan_G:
I did that while ago, i think with comm on positive terminal I got 0.564

This was on the international version
[Galaxy Note II Android Development] flez1966:
I have a UK version and on resistance I see nothing. Some meters use a very small voltage to test resistance so as not to see leakage on diodes etc, use diode test feature to double check.

What is an old usb cable worth?

Cut it open and use the red and black on the pins?

Take note i do not have a working touchstone so cant confirm charging, but i see no reason for it not to work, i may just go find an old usb cable and test it for you etc
[Galaxy Note II Android Development] flez1966:
ok heres a video, watch and enjoy....

voltage readings etc

I could have screamed ''bas***d'' at it when it worked....

Great video :good:
[Galaxy Note II Android Development] dixonwa:
Thanks for the video.

I just did the same checks with the meter as you showed in the video on the US T-Mobile version and did not get any readings, even using diode testing setting. The negative was still shorted to the metal on the sim card slot though.

Hopefully someone will be able to figure this out because I would love to have wireless charging in the car.
[Galaxy Note II Android Development] vinas1:
The test on the T-Mobile version was done days ago on this thread. The negative terminal is grounded to all the screws, negative on the USB jack, SIM card slot, etc. I jumped the positive pin from the USB dongle to the positive wireless charge pin and the wireless mod began to work, so that tells me that the ground is good but the positive pin on the wireless charger is not active... I'm going to disassemble my Note 2 sometime in the next few days and see if I can bypass any blocking diodes, etc. At any rate I'll take some pics this time and share what I find. :good:

---------- Post added at 08:23 AM ---------- Previous post was at 08:20 AM ----------

Sorry I just saw this reply - no I did not do a diode test, but I can by this weekend. We need a new thread for the T-Mobile Note 2 so that we can more easily track our progress with this problem.

[Galaxy Note II Android Development] harpocrates:
That isn't conclusive as software could control this to have the circuit open.. that's why I'm asking for a log from international users that have it working... i just need one log.. to see if it can be enabled through software..
[Galaxy Note II Android Development] harpocrates:
Well in the origibnal post it shows that the screen shows a message that wireless charging is enabled...im trying to see what the software does when that happens..trying to find if the software is enabling something which is disabled by default in the tmobile version.

Thanks for log.

I use logcat and would start it before placing it on wireless charge, place it on, see message op has in screenshot..take it off charge..stop log...im hoping you did something similar..im super [panicked at work right now cause i forgot i have a business truip to florida next week and have oh..maybe..a million things i wanted to get done before that..including some tests in lab for the client iam meant to go out to....ahhhh

so might look at this next week..or sunday while im flying :) If you can get a second one too.or if anyone who does get the popup on their screen can send one so i can compare...thanks very much..

Are you using wireless charge method or did you use usb hack to solder the wires from coil to usb? And did you pull off the device from charge before disabling log? Can you repeat that and do it that way if you didnt?

I used the internal charge pins only, not the micro usb, i went charge/stopcharge/stop/charge/stop, each charge was about 5 seconds with a 5 seconds off.

and yes i was 'off charge'' to save the log, as i didnt have enough hands lol. and no i did not solder to my phone, i just held the wires on by hand.

the two pastbin dumps are of the same thing, one called charging [ http://pastebin.com/eHGUiuAk ] which is the touchstone method with two wires inside the phone on the wireless charging port, and the other is with the official samsung charger in the micro usb at the bottom of the phone.
