Modding my i9023 to have induction charging. Need...... - Nexus S General

'Sup XDA. I've been dying to get induction charging on my Nexus S since I got a Touchpad. Even found someone who did it over at androidcentral. Have all the parts.
I know full well that I am completely responsible for any screw-up I happen to do.
Now that that's out of the way, I just need to figure out which pins to solder to. HERE is the teardown and just wanted pointed out which pins I should take the soldering iron to. Any help appreciated.

Nobody?

He didn't take pics the first time around and said he didn't want to open it up to take pics. I just need to figure out which points to solder to. I have everything already here.

Here is one someone did (with video) to their Galaxy S. Looks clean!! I would love to do this mod.

Can we get by with soldering only one wire in the Nexus S as well? Provide 0V using the sim card tray?

I'm totally thinking I'm gona do this

wish I would have kept the back from my palm pre, I do still have a couple touchstones though. Might be cool to put an NFC tag in the touchstone to launch the dock mode. Might do this if I am feeling adventurous one day.

Can you just program any passive tag for that? Should just be a step of sticking it on right?

Wow, this looks awesome.
But if I understood correctly the problem, the NFC antenna must always remain between the inductive antenna and the battery. I haven't tried, but it seems that the NFC antenna can be simply removed. Wouldn't the inductive antenna fit between the NFC antenna and the case? That way it would all fit inside, leaving the awesome exterior untouched.

There's a risk that the antenna would have 5V running through it and consequently through the NFC radio/parts, etc. if you keep the coil inside the case behind the NFC tag.

I think so. I havn't messed around with an NFC task launcher, but I remember reading a thread where people were using an NFC tag to launch car mode when placed into a car dock. Should just need to buy a tag and set it up with an NFC launcher.

Official Docks for Defy?

Anyone tried putting a magnet next to the back of their Defy?
I have this leather case for an old XDA I used to have, which has a magnet built in to clasp the strap closed.
When I put the defy in, it came up with a multimedia dock interface!
Also, putting the magnet at another point puts it into the car windscreen dock interface.
I looked on the Motorola website for the accessories, but they list the milestone multimedia/windscreen docks under the Defy accessories.
Correct me if I'm wrong, but I think the Milestone's usb port is in the wrong place to fit?
Yes, the milestone won't fit. I'm waiting for a desk-stand, too

Problem is, it'll switch into car mode every time you use that...
magnet polarity
Turn the polarity of magnet!
If you put the magnet same place like in the car mount (behind of the menu button), but with reversed polarity. The phone runs the media home instead of car home.
I understand that's how it works.
Thing is, how easy is to to get to the magnet?
Are you likely to end up ruining or breaking the dock whilst trying to remove and reinsert it?
If you don't want the magnet to work, can't you put the phone in upside down? Most of my apps work fine inverted. I realize that puts the usb on top...
I just bought a cheap mount from China on eBay now. No magnet

That actually looks quite nice and the price isn't too bad either.
Just a shame it's not in stock really - I'll keep an eye on it and if I see it's arrived, I might just go for it.

Looking at it again, my only concern is where the charging/USB port cover is supposed to go when it's docked.

[Q] Is a rear facing camera mod possible?

As many have noticed Asus left the mount for a rear facing camera inside the nexus 7 even though they later took the camera out. My question is, what would it take to install a camera into that mount and get it to run? My guess is all it would take is the right camera and a connector that could be installed into the board beside the camera mount where the old connector was. Of course a hole would need to be cut into the back cover which may interfere with the nfc antenna. Or would it? Would the firmware of the device need to be messed with, or would the camera work with any camera app like normal? If you have any ideas on how this could be done please reply. I would like to try this but it may be more difficult than I'm thinking.
I haven't taken much time to look at the inside but I plan to put some LEDs between the speakers so it will glow. So I'll look tomorrow but I don't think there is a place to connect the camera.
As far as the antenna, if your careful enough you could lift it up and move it. And just solder a wire on it to run to the connectors
But this is if you could find a camera and get it to work

I believe there is a spot on the right side of the mount where a connector was supposed to be soldered in but was left out. I wonder if Google or Asus would tell us where to get the connector they originally planned to put in that spot. I doubt it.

Replacement camera modules are surprisingly cheap. From $10- $40ish. You would just need to find one with the same connector and many seem to have one or an other connector. So if you could find the connector and attach it to the board finding a camera to connect to it may not be too difficult.

Soldering Micro USB Port

Is there anyway I can just solder a generic micro usb port onto the board (This one: http://www.ebay.co.uk/itm/New-ASUS-Google-Nexus-7-First-Gen-Charging-Port-REV-1-2-/141138826759?pt=UK_iPad_Tablet_Chargers_Sync_Cables&hash=item20dc879607), reason being is that everything works fine except for the micro usb board (a pin broke when I was trying to fix it) how easy would it be to do it and can it be done?

You're just wanting to pull the port off the new board and soldier it on the old board? I don't see why it won't work so long as the joints match up and the legs are not to long. The pin out should be the same. I think you should be fine.
Edit: I guess I should have looked better. I don't know if the first gen has the same layout as the 2nd gen. I can't say if that whole piece will fit right.

The only thing which is standardized about the connector shell is the mechanical details of the mating portion of the connector. How the rest of it mates mechanically and electrically to a supporting PCB/PWB does not need to be standardized at all. So, if you happen to end up with the exact same connector, then great. Just any connector? Not so much.
You might be fine attempting it, but there are risk of damaging the PCB (cracking vias barrels from their land pads (too much heat), accidentally tearing surface copper pads off during component removal, etc.
A good electronics technician will have a number of tricks & techniques for rework/repair operations (e.g. using an excess solder flood during component removal), but chief among these is being able to carefully control the amount of heat being applied (tip choice and a variable temperature controller for the iron).
I bring this up because the cost of everything you need to perform the job well exceeds the part cost for that whole headphone jack/USB port flex cable assembly (US $50) unless you have those good tools already. (I have to suppose you don't; otherwise you could have answered your own question)
If you can find the right connector shell and are determined to do the job with a cheap soldering iron, do yourself a favor and at least buy some paste flux (Kester?) and some fine copper "solder wick" braid along with the solder you buy. And it is probably also a good idea to disassemble the N7 so you are not trying to perform the repair "in place").
good luck

Wholly crap hib i didnt see it was you, ya im on a guys gs5 selling him a wireless charger and noticed gs4 reciever works fine. Nice to see ya!!
The cover is really, really annoying. Especially for me, who uses bluetooth through my car speakers for my main music stuff. So each time I get in the car I plug the phone into the 12 volt. And each time, I have to pry open that cover. The worst part is, it doesn't even stay open! I also just got my Incipio dual layer protection case in the mail and now its even harder to get the charging cover off. It's really aggravating. I don't even think it closes correctly either. It always looks like its not snapped down all the way. Just, bleh. Most annoying quirk on the 4 Samsung phones I've owned.
just get the spare battery charge kit so you never have to mess with it. Its also a better means of going from zero to 100 than wireless charger

Yeah I'm not really sure what to do here. I have a bunch of 3D models for phone docks / car docks / etc for the gs3 and gs4, the battery cover is a total nuisance on the gs5, especially because it doesn't really stay open after you open it (I'm trying to imagine how to go about designing a dock for this thing).
I do 3D modeling and have a 3D printer, if anyone has an idea for an improvement... holler. I doubt we'll see any kind of other 3rd party replacement otherwise as it's attached to the phone and clearly involved with waterproofing. not sure if it's worth the trade-off!
anywho guess I'll be giving wireless charging a try again...
If you take off the battery cover there is a screw where it holds the USB cover just take it off your not prone to accidents

Yeah definitely good that it's easy to do that - personally I'm not really upset or frustrated; it's awesome to add waterproofing - I'm just trying to puzzle out the best way to keep the feature while also making the phone easy to slide into a dock (preferably with one hand), you know?

Where exactly is the NFC chip in the device?

I have been using NFC with success. But I'm not certain exactly where the NFC chip is. I've just been sliding the device on NFC readers till it works . Has anyone found a graphic, that shows where the NFC chip is at?
Email the people at ifixit. They're probably in the process of tearing one of these apart.

It's actually not a "chip" but an antennae.
It's probably located somewhere central in the back.
