Powermat Mod for MyTouch 4g

Can someone give me a hand here.
i have a powermat received which has 2 wires on it a red and a black, and i am trying to find a way to connect theses wires to the 3 side pin connectors on my MyTouch 4G.
anyone have any ideas on how to do this,
Please all help is greatly appreciated

Lol that looks like my pic lol.. I wanted to do a powermate for my phone to, but jus a fyi, you wont get a AC quick charge from the pins, it will be a usb charge..
But all you gotta do is what you see in the pic, red pos on the left pin next to volume rocker and neg on the pin next to the usb port.. If you want you can put the neg on the middle pin also, that will activate desk mode when you charge ur phone..
Good luck, and show the final product when done..

yeah i got that i idea, but how would i be able to keep it hidden?
I just went and purchased the PowerMat Door for the Droid X and as you can see in the pics below it has a Micro usb connector on the battery door it self.
Maybe cuttign a custom sized door to fit the MT4G, what do you think?
you see what i amtalking about?
Oh and P.S. it is your pic LOL

Do you this it can work?

Sorry for the late reply havent been on here for awhile!!! Ummm the hardest thing would be to find away to hook it up to the pins.. I know there is already a power extender thing for the mytouch but looks ugly lol.. I would say try to get another batt cover for cheap and see if you can mod that with the power mate..

I prefer to use touchstone kits for modding from the palm pre, I find it charges my device the same speed as the A/C charger when I hook it up by soldering from its leads to the usb port on the device. It may require a nearly complete tear down of the device, but that gives you all the protection of the charging circuits and the fully charged message on android etc so your device will stop charging, if you hook it up using the 3pins on the battery connector then you are bypassing the charging circuits, possibly with disasterous effect, but certainly with no way to stop charging other than removing it from the charging mat.
Hope that makes sense...

I have many touchstones from the palm pre (my old phone). This is a great way to do the mod, wondering if you have any pics of internals after a mod (any phone)

Wireless charging mod.

I cannot wait for the official galaxy S3 wireless charging kit to come out.
I got inspired by the Galaxy mod that was done by using parts from a Palm Touchstone cover.
ww.qianqin.de/2011/09/28/high-waf-inductive-charging-mod/
I am pretty sure, that I don't need to do an intrusive operation as the one in the link - I believe that Samsung made pins ready for it under the cover.
Does anyone know what the two 'pins' that are exposed to the left of the battery are for?
Thanks!

There are countless threads regarding the "pins", wireless charging kits, and that mod.

I have a touchstone. And a back, and would like to see if anyone has applied this to the S3 and made it work

I have a feeling the wireless charging module will interact somehow with the two pins next to the battery. I was planning on attempting this mod using these pins but without a multimeter i am unable to tell whether these pins can be used and which way round to wire them up. If anyone can assist i would be grateful.

Yes. Countless threads about the mod for the Galaxy S, but I haven't been able to find anything about pins on the Galaxy SIII.
- Maybe I'm just bad at searching, believe me I have tried!

I also would love to know if and how someone gets their sgs3 working with the palm touchstone! Hope it is not too difficult!

I have finally managed to find a page that claimt that the two pins next to the battery indeed are for wireless charging.
ww.trustedreviews.com/samsung-galaxy-s3_Mobile-Phone_review
Only problem is, I don't know Trusted Reviews - so I don't know how 'Trusted' they are?
All I need now is to find out which pin is 0V and which is +5V. (I'm pretty sure that the current is the same as the Palm cover provides.

Every accessories are always made for on pin, hdmi,wireless kit etc. Always Samsung market tactics.
I wish you'll do it.

Upper pin is plus, lower minus - and it has also be done!

Yes it works, it will be a little slower, im only seeing 450mah going in as opposed to about 1000mah
But that doesnt matter in the slightest as i mostly charge overnight

that is great news! That does not look too difficult and it looks as NFC is not touched. Just the translation is difficult and not knowing what samsung wireless charging is about.
I also wonder how snug the fit is after adding the magnets from the touchstone back cover?

I will post details soon when i am back home

I'm still waiting for my touchstone and palm battery cover to arrive...

I found this! He looks like he did a great job. I am just curious if he had to solder anything to the phone?
http://www.youtube.com/watch?v=uAqP3T_Mbzg

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!

please post pictures and a possible video. This is so interesting!

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?

I wonder what happens when you plug in the phone with usb while it's inductively charging.

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.

Sprint's backplate covers the inductive charging leads - Successful Mod!

Which is one feature i really would have liked.. but popping the back open, I see the two leads for NFC, but the two leads near the right side of the battery for inductive charging on the international version is not on the Sprint version.. sad panda face
-- UPDATE -- Successful mod
I had to order a Sprint specific backplate from ebay
So I got the Nexus Wireless Qi Charging Orb.. and I drilled two small holes in the spare Sprint backplate I had.. I then proceeded to use some copper foil, folded it up a few times, and placed them in the hole with the sticky part on the housing. I then made sure the bottom of the folded copper was down enough to make contact with the contacts on the motherboard. Closed it up and then placed the receiver in the holes with the copper foil. Placed on the Qi charger and boom.. Wireless charging..
I did it this way so I can replace the middle housing and it won't look like I modded the phone if I need to take it in for repair.. Also, I can charge it with the Seidio Surface case on.

similar to wireless charging, but you lay the phone on a Charing Mat, and without the cords, the phone starts to charge .
Though OP, you're saying that it can't be easily fixed, with a Replacement of the cover? is that it isn't literaly on the phone itself?

I have the T-mobile and am about to modify mine for wireless charging just like my Verizon S3 is... It has already been confirmed working so I know that the T-mobile version has the same pins as the International does (which is GREAT) but I think it may require some stronger magnets this time around. LOL

I think this can still be done I have to ask some folks I think you can run a connecting line to the battery connections through using copper tape, if this is so we just need someone with electronic know how but google copper tape you will see its thin conductive tape that can lead anywhere Im wondering if this mod can be done that way..
Ps can someone take detailed pics of the back of the phone with cover off, with the battery in and out thanks Im trying to think of a solution

Here are pics

They are there they moved them up see the connection pos and neg are there just in different places top right next to speaker or is that nfc only someone let me know I don't have the device yet if so maybe you can run two leads from the battery connection pins on the phone but that's just a theory I don't know if the connection will charge your the battery once I get my phone I will attempt to mod with battery connection pin hijack to copper tape to induction coil.

That is NFC. .. on the International and Tmobile ones, they have those and two more to the right of the battery.. if you look on the back cover inside there are two pins for the NFC that connects to the back of the phone in that location.

I dont know but sprint really *ucked this model up if they would have left it alone like tmobile we would have been fine Im looking for a solution to the wireless charging but i dont know if its going to be possible all because sprint wants to be different and difficult. Ive been with sprint for 15 years but my patience is wearing thin.
Im still going to attempt a wireless fix though

whats this need yall help
Can someone help me, I dont have the phone yet so im trying everything in theory, to get wireless charging going. so I have questions!
What is this box
Whats the box for it doesnt look like nfc or a speaker or a microphone so Im hoping its tied to some sort of wireless charging, maybe a cover with the charging pins underneath (wishful thinking)

Personally I think wireless charging is overrated. There's a cable plugged in somewhere to get the pad going. And you can't use the phone while it's charging. Well, inconveniently you can. And it charges quicker via a cable.

[Q] Adding Inductive Charging?

In your opinion, how hard would it be to modify a case/back panel for the Glide, so that it has inductive charging support? I just saw a video online of someone internalizing an iPhone 4/4S charger, with only slight structural modifications (it had the appearance of no case on the outside), and was thinking that I might be able to do it to my Glide. At the moment, I am using a Body Glove case, made of rubber-coated plastic (the only one AT&T sells/sold for the Glide), and my best guess is that the case is about 3mm in thickness. I am looking for no actual phone modifications here (except for wiring the case to the battery, and maybe a modified back cover), so does anyone have any thoughts/ideas/suggestions?

Interesting. There is a company selling those inductive charging mats. I believe there is a connector that plugs to our phone (micro USB) to work with it. You could buy that and try to modify the phone back panel and a case to add the necessary hardware.

I saw this, and figured that's what I was going to use. However, It looks as if the case for most phones adds quite a bit of thickness. I looked at another guide, which involved ripping up a Palm Pre back, soldering some things together, and using the Touchstone mat. As for whether or not that would work with a Powermat, I am not sure.

I've seen that guide, it was for the galaxy s3.
It looks like that phone has the two charging pins below the back cover; looking at the glide, I can't see them.
I fear we would need circuitry or at least more complicated wiring to make it work.

The one I saw was for the original Galaxy S. You may have seen a different one. The video I saw showed him wiring some things directly to the battery, if I remember correctly.

any progress
Hey there!
I found this thread as THE only one where someone imagining about the glide having the possibility to charge inductively.
any new info about it?
@a_p3rson: did you find a way to do it?
I would love to see it becoming true..
best regards

So far, the best chance I've seen was using the induction sticker on the back for the Palm (pre I believe), and wiring it to the USB port. I think that would work pretty well, though I am worried with how it would affect the normal function of the USB port. If anyone wants to try it (and share the results), by all means, please do so!
EDIT: It wouldn't be possible to wire the sticker directly to the battery, right? Of course, without causing overcharging/overheating/general harm/etc. to the battery or any part of it?

just throw it out there i have a extended battery from amazon it is about twice as thick as stock batter new back cover has large empty space between camera and batter pack i mean could put flash drive with room to spare in there would be easy to add some new hardware in there if need be for you power matt bought mine of amaxon for 11.00

I seem to remember the sticker on the Pre being really thin - like paper thin. Plus, I really am against cosmetic things like that (e.g. large back, extended battery), so an extended back shouldn't be needed.
However, I do know that the guide that I found (for the Galaxy S) said that it was possible by just wiring the sticker to the charging ports in the USB connector. The only worry I have is if the phone's USB communication would be affected at all.

If it is possible to just directly wire into the charging ports, there appears to be an easily removable panel directly above the microusb port that would presumably give access to it. I'm at work right now, so I can't exactly check, just puttin it out there.

Did you ever see if it was possible to hook the induction sticker to the USB port from here? I just looked at the panel, and it actually looks like there is a sticker that contains some wires going to the main board on that plate, makes me think that it could be an antenna of some sort, and that it might be kind of hard to deal with.

[Q] Wireless Charging Mod Question

I have been reading some very interesting posts about adding wireless charging capabilities to a Samsung Galaxy Nexus. Although it seems like every mod requires a touchstone coil, which also requires a larger back cover. Browsing ebay I ran across a "patch" of sorts that goes between the case and the battery to add the inductive charging. I was wondering before I buy it and rip apart my beloved phone. Could I just solder the "patch" to the pogo pins on the side of the phone and would it charge? Or am I missing a component? Thanks in advance for any help!
On Ebay it is called "Qi Wireless Charger Charging Pad + Receiver Kit for Samsung Galaxy S4 S IV i9500"
Also this is my first post, so any comments would be helpful too!

Isn't it for the s4? So I assume it doesn't work on the Galaxy Nexus..

That's what mods are all about, people have successfully mod the palm touchstone coil into their phone and it works flawlessly.
In theory this would work, but how OP are going to connect it to the pogo pins, that's another problem.

Oho Thank you. it very good

Well I was thinking that if you take the phone apart there is a spot where the pogo plugs connect to the circuit board. I thought I could just solder a thin gage wire to the leads, but does that patch have the correct circuits to supply 5v with the right amount of amps?

Check the specs of the induction charger.
Anyway for the touchstone mod, others used a copper tape instead of a wire.
Beamed from my Maguro.

I have a s3 a couple of the s3 qi cards. I have my gnex as a backup and did the mod myself. If you peal the top label off the card around the pins you'll be able to desolder the s3 connector and solder a couple wires. I used a couple fine wires I removed from a old ide cable. I then used a dremel tool to cut a small rectangle under the battery door and behind the pogo pins to connect the wires. I used a very small cut off wheel, took my time, and cut shallow and never took the phone apart. The pins are easy to solder to and much safer. This did disable my pogo pins, but I have no dock so I don't care. I have the Samsung OEM 2000mah extended battery and back cover. This leaves me a small gap to lay my wires without any battery door bulge. My ditztronic case still fits perfect and the wireless charging works great. Its worth noting that the qi pad will provide around 600ma, which is fine since the dock pins charge in USB mode anyway.
BTW, while I think the safest and easiest way to get to the phone's circuitry is to cut that small hole, you are putting a dremel to your phone so I am in no way responsible if you somehow kill your phone.
