Xperia ARC induction wireless charging mod

Just finished the Sony Ericsson Xperia ARC induction wireless charging mod
http://www.pbase.com/xperia_mods/xperia_arc_induction_charging_mod
Pls look at this reference video to get an idea what you are going to get and what it takes:
http://www.youtube.com/watch?v=0ga4N_Ih9GE
Parts you will need for this mod:
* Palm Pre back cover and Touchstone dock (8-15$ on eBay)
* Self-adhesive copper foil
* thin wire
* small star and maybe Phillips screwdriver
* thin soldering iron
* solder
* 2 ohm SMD (1/8 or 1/4w) resistor is needed to balance on peak. Will not work without it.
Guide to open the phone(you don't need to open it all the way as on that video! Just few first steps): http://www.youtube.com/watch?v=ae-WQkNh8mE
MIND two restrictions:
1) this induction wireless charging will not work from PC or Laptop USB plugs (at least for me) looks like cradle needs a bit higher voltage then 5v. As USB is usually below 5V (~4.8). It can be due to the presence of resistor.
2) it won't work through almost any case / jacket / cover if you put it on you ARC. As it becomes too thick to let induction and magnets alignment work. for this you need to put induction coil in your case as I did for RAY http://www.pbase.com/xperia_mods/xperia_ray_induction_charging_mod
Q: Will it interfere with any phone functions and radio modules (GSM, WCDMA, WiFi, BT, GPS ...)
A: NO all works as good as before.
Q:Is this really worth opening your phone, and probably damaging it?
A: It is up to you. For ARC I'd say it is worth opening as you need to open only one back cover, no modules disconnect, connect etc. If you feel experience in opening the small electronics and soldering go ahead!
Q: Also, what about the charging times? Is it as slow as USB charge, or almost as fast as wall outlets?
A: Charging time is almost as fast as wall outlets. Charging current is around 350 mAmps
Q: Can I use it in the car
A: Sure!
Q: where do we have to put the resistor?
A: just in line of + or - like in this sample
http://www.pbase.com/xperia_mods/image/141117444
Q: Will my Micro USB port work after mod?
A: Yes it will work as good as before and you can charge through it as before
Q: the cover is closed complete after install?
A: Yes, you will not notice a difference from the outside
I HOLD NO RESPOSIBILITY IF YOU DAMAGE YOUR PHONE OR YOURSELF DURING THE PROCEDURE!
This mod might void your warranty! Though I don’t think a SE repair man will be able to find traces of this mod on first sight if removed cleanly.

Very interesting, but where do we have to put the CMS resistor?

I love these kind of mods. It is it's time ahead. It probably won't take too long before stuff like this will be general.

I tried and damaged my xperia mini pro. I didn't followed this instrutions so I didn't used the Resistor. It charged for 2 seconds and it just stopped working. I heard a small noise and it stopped working. Now my phone is not charging very well and USB is not working.
Do you think it was a peak due to not use the resistor?
I already ordered another phone and palm circuit, just don't like loosing!

Interesting...... very interesting!! but doesnt look like many people have tried it....
Im sure more and more mobile devices will start to use this technology soon

n4s, you nuked either the USB connector, a voltage resister between the connector and the board, or an element on the board itself, send it in for repair or seek expert advice.
OP might want to make that disclaimer a little bolder as peaks get expensive.

This would be great for pimping my Arc S.
This inductive charging is getting the new standard, it's called "Qi".
The latest Nokia 920 has it, so does the HTC DNA (full hd display too!)
The next step would be to also transfer audio in this way. So all you need to do is placing your phone in your car kit, and it automatically charges ànd creates and line out signal for your car stereo.
Again the Nokia 920 already has this implemented (and the best smartphone camera ever, apart from Nokia Pureview) Too bad it's not running Android...

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.

Impressions

Been playing with the watch for about an hour.
First boot:
Needs Android Wear and Moto Connect apps.
Downloads an update.
Needs to be around 80% before it can be used because it needs that battery to install the update.
Android Wear is Android Wear so all the swipes needed to get to things are here.
Size : Not bad at all. I thought it would be bigger but its a nice size. It depends on wrist size of course.
Band : Didn't seem like it is easily replaced. But I don't know a ton about watches. It seems to connect into the watch somewhere, that might be something standard though. Didn't look in the manual to see if there were instructions. (Edit : Included manual doesn't say anything. Site - www.motorola.com/mymoto360 - doesn't seem to be up where there is supposed to be a full user manual)
Battery : Way too early to tell, some drain right up front but there is a lot going on with syncing and all. Need to look at some Android Wear info to see how to get notifications beyond email and Google Now.
Charger : Comes with cable connected to the adapter. (Not a USB cable + Adapter). Screen dims while on charger. Button brightens the screen. Would be nice to see notifications on the charge screen.

Can you flash a picture up of the charger and associated cable please. When looking at the image below it looks like a SB cable plugging into the charging cradle... if so then its a possible way to get fastboot connectivity, if not then I'm back to the drawing board (not that I can do much until late October anyways).

The connection on the base is MicroUSB. So a USB can connect to it. But the charger that comes with the Phone is all one piece (not a seperate AC Adapter and USB cable). It is outputting 5V at 550ma.

Gotcha, cheers. So looks like PC connectivity would go through the charging cradle. Curious to know if the inductive charging standard they adhere to allows data transfer as well... Motorola must have had some way to debug it when creating firmware etc.

I think I remember reading a while ago that it was planned in other, less well known inductive charging standards, but I'm not sure if the current standard of Qi changing has it.

That would mean it would transfer data via bluetooth from the PC. I'm not seeing it connect like that. There would have to be another method.

Thanks for providing pictures and giving some insight for what to expect!
Could someone who has the watch please snap a pic of where the strap connects to the body?

I believe Qi does have data. But it is limited to 2kbps and is used for basic communication.

Does anyone know how the band actually comes off yet?

It seems like you would pop the back off somehow.

Actually seeing how the strap connects to the watch, and seeing exactly what the deal is with the metal straps, is like trying to solve a National mystery. I swear, the Illuminati are laughing at me, wringing their hands, and saying to themselves, "...And you will never know, DUSTY.".

There was a picture of the metal band and it looked like the connecter was non-standard. Like the end was a bit longer. Seems like they could have put some kind of door so you could switch out the bands easier. There has to be a way if they are going to have both leather and metal band versions. And in the Verge interview it seemed like they were planning on having options.
So far my only complaint is just with Android Wear. Like swiping away a gmail from the clock but then wanting to bring it up later. Seems like once it is swiped, that card is gone.

Dead Pixel
Drove all over North Atlanta and got the VERY LAST ONE with the Grey strap...everything seemed cool except for a DEAD PIXEL but I have my receipt and am hoping for an exchange whenever restock hits the stores.
One more thing to note...the device had like 35% charge which allowed me to pair to my Nexus 5 but then started displaying a charge battery notice.
I like the Motorola app that gives me a quick update on the current charge levels...connected to my Energizer QI pad so I think that I will just ditch the cradle charger that it came with unless I travel.

UPDATE: Figured that this may have been a crappy unit...the dead pixel is still there but I did a factory reset and it is downloading an update. When I unboxed and I first turned it on it seemed like it was having issues from the get go...now it seems to be running smooth like a champ albeit 1 bad pixel.

They all do that if not fully charged before turning on. You should be GTG now.
They should really mention the need to charge it before trying to set it up.

Sorry man and not to turn this into any tech support forum but just want to confirm that even if the battery got charged to like 65% there was no way to get past the "Charge your battery" screen unless it is either fully charged or charged to a certain capacity?
I did a factory reset and was able to get to the part where it downloaded an update again, rebooted and then immediately came up to that screen which can't be dismissed. The unit is pretty warm so I have placed it on the dock and will check every hour to see how if fairs...just frustrating that it couldn't even start. I am contemplating getting a refund and seeing how others react to everyday usage. I say this based on the fact that you go to the Moto 360 support site and it doesnt have anything under Help Topics...even after you login with a G+ acct or a Motorola acct.
I understand that statistically 1 out of every 100,000 may be the defect and if that is the case then it is what it is...was really hoping to test out a physical watch finally for an app instead of an emulator.

Wired charging not working - Help identifying a broken component

The charging port on my Nexus 7 2013 starting playing up and only charging when the cable was held in certain positions and then finally it stopped working altogether.
I took it apart to replace the port and the problem was that the legs on the connector had actually lifted the tracks off the board.
I replaced the connector and wired the legs to the nearby pads the tracks I believe they're supposed to go to and when plugged in both the charging symbol appeared and usb data communications worked.
However I then had a slight mishap while handling it and managed to knock off and break the component pointed to by the arrow in the photo.
The component has no markings on it and is about 2mm x 1mm. I can't measure the original with a meter as it's physically broken.
Can anyone tell me what the component is so that I can replace it?

I meant to also add that while looking for info I came across this site regarding the port repair which some people may find useful although personally I think you're better of removing the sub board and then using a proper desolder station if you have access to one.

This component has a sub-ohm resistance and is a fusible resistor or choke/inductor. Either way you can just short/bridge it - no worries

Thank you very much for the reply, that's just the kind of answer I was hoping for.
With the link bridged the device does show it as charging when plugged in however the charging rate is now really, really slow and at it's current rate of charge looks like it'll take about 50 hours to fully charge.
If I put an ammeter across the two pads then it looks like it pulls about 85ma whereas I'd expect it to be more like 10 times that.
I've tested it with several cables and chargers (0.5A, 1A and 2A) that used to work perfectly with it previously and still work with other devices..
I've ordered an inline usb ammeter that should arrive later today to double check the current usage but the charger or battery don't get warm so I'd guess it's correct.
The repaired tracks look to be correct and beep through fine, the data cable works and I can transfer data but presumably there is something else wrong with it.
Any suggestions of what else to look or is there anything that I need to do with software to reset the charging process?

The ammeter's internal resistance may trigger N7's lower charging current draw which normally happens to prevent overloading USB2 or weak chargers.
Anyway, do a recalibration:
fully discharge N7
recharge it completely while off
disconnect the charger and turn N7 on

Thanks for the reply.
I added the ammeter inline as it was charging so slowly and the 85ma it looks to pull roughly equates to the charging times I'm seeing.
The tablet is fully charged at the moment (via a wireless charger) but when it's not needed for a few days I'll flatten the battery and let it charge using the cable, I'd guess it'll take 2-3 days to do so.
Interestingly apps such as ampere show the sort of current I'd expect the device to be getting in the 800ma range however I'm guessing it's calculating this as the requested current but it's just not making it to the battery for some reason.

Car install Questions

Hello XDA members and fellow nexus 7 owners!
After reading these forums for months or even years i decided to get a Nexus 7 2013 myself. It took me a long time since they are not being sold that much in the Netherlands.
Upcoming Tuesday it will be shipped and i can not wait to be able and install it in the car.
Setup? ---- I am going to run the nexus 7 together with my 1 din car radio. Which means i wont be using a dac or anything else just spotify over bluetooth to the car stereo and that is it.
The only addition i would like to have is a backup cam since i am terrible at parking... go ask my rear bumper he will show it.
Now i know about rooting and all that but i would like to know which camera to buy. I have seen people using a easycap and i can get one on ebay. But which setup are you running or do you recommend me to get? Any ebay or aliexpress links will be appreciated. This way i can buy the stuff and know it will surely work.
And yeah i been searching through forum and reddit. But everyone is using a different setup of rom and hardware which just makes it confusing. I already have the usb otg cable and thats basically it.
Thanks in advance!

Prepare for a world of hurt. You'd need to find a real UVC adapter then start the app each time you want to back up.
UVC and EasyCap are terrible for start up times, 4 seconds to show on mine. Oh, EasyCap drivers aren't in the system by default, the need to be installed and loaded on boot with a script.
The latest thing on the Timur's forum was to use a USB camera. Problem with that for me was they're housing are terrible. not suited for cars at all.

thanks alot for your reply! i decided not to do the cam install as i been reading alot of issues indeed! My nexus 7 was delivered today. Now im just having issues with charging in car and how to do that. I think the 2.1a car charger i have should be able to keep it at 100. Since it keeps my phone galaxy s8+ at 100 using navigation spotify and such

Are you using this in car only? The problem is the tablet can use power faster than it can charge, especially when using navigation.
Mine was fine for about a year then it started not keeping a charge. I did the battery removal mod and couldn't be happier.

I just dont understand how that battery removal mod works. Or what i should do to achieve the same thing. Not really a genius with eletrical work unless i see pictures of everything then it is easy ofcourse.
Seems like no one in holland has this lmao. O yeah and here its only 1 week hot outside like 30C max so i dont know if its needed.

It's not so much a heat thing as the battery will drain in use. It simply can't charge fast enough. I had the problem even through winter.
I guess I left out the part where I should've mentioned to use it with the battery and see if there's an issue.
There's info but not great info on the removal mod. It's straight forward but it need "large" wiring and a power supply over 1.8amps.
Hook everything up, without installing right away, and get a feel for it. All the little details will show itself.

Again you are so right! I have had the car install now some days and it drains more than it charges xD the gps is also bad which sucks. But using waze it goes into -200 mA and with only spotify on and no navigation to +150 mA. I will really need to check that battery removal mod. How did you do that? do you have some old pics laying around or a scheme? I even tested 2 new car chargers i bought 24w 4.8a and neither that keeps it charging pfft.

Again you are so right! I have had the car install now some days and it drains more than it charges xD the gps is also bad which sucks. But using waze it goes into -200 mA and with only spotify on and no navigation to +150 mA. I will really need to check that battery removal mod. How did you do that? do you have some old pics laying around or a scheme? I even tested 2 new car chargers i bought 24w 4.8a and neither that keeps it charging pfft.

What do you mean "GPS sucks?" As it doesn't lock on satellites, or it just drains the battery more?
The battery removal mod is pretty straight forward.
You'll need an adjustable 12v power supply that puts out over 2 amps adjusted to 4.4v. This is the one I have: https://www.amazon.com/gp/product/B00C0KL1OM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Find an old power supply you have lying around, like for a router, and use those wires. If they're too thin the tablet will be unstable.
I'd probably look for an extra battery online in case you want to revert. And this is the part photos are needed.
I'm having problems finding the ones I saw when I did it. I'll look some more and if I can't find them I'mm take some myself the weekend.
It just involves separating the battery from it's controller and soldering the voltage regulator in place of the battery. The ground has to connected to one of the tiny black wires at the controllers connector and it's done.
I wired the voltage regulator into my radio's constant power supply and I still use a charger to the micro USB to turn it on and off.
-edit: oh yeah. here's the video from the guy that discovered the mod: https://www.youtube.com/watch?v=9N2Bh4fI8Bo

Thanks again for your reply. I just checked that video it seems doable.
With gps i ment the lock on satellites. I found someone who was using a kind of re radiator if that is what it is called and im thinking of buying one.
I think i will just start soldering and doing that battery removal trick. Do you think i could do it and just plug it into a anker car charger? It is 5v 2.4a each slot. This is the one https://www.anker.com/products/variant/powerdrive-2-ports/A2310012
Or should i go for a dc to dc regulator as you have? I have currently 3 of those car chargers laying around all different brands but same watts.

Here's a photo someone else posted just the other day. The second wire is ran better than I did: https://forum.xda-developers.com/showpost.php?p=76554736&postcount=464
I use a 5v supply when I work on my tablet in the house, but I've heard 5v could cause problems with the tablet not recognizing when power is connected to the micro usb.
My GPS was terrible at first. Long lock times, if it locked, would drop satellites spontaneously then come right back. I even bought an external USB receiver. Then it just started working.

I guess there is just 1 way to find out if the car charger works hehehe i will give it a shot see what i manage to do. Still looking for a housing or anything to mount the tablet in for my car a renault megane II from 2003. Seems like i will have to mold and fiberglass it.
