[HMOD]Wireless Charging for home and on the go

This has already been done for the EVO 4g using Palm Touchstone capable scraps but I want to take it to another level. Since i'm not much of a programmer I can add to the community in this way.
Please let me know how many of you are interested in this. I'm going to put up full walk throughs as I move along but I will also sell some off (in the marketplace) for those that don't want to go through the hassle. I'm going to start ordering parts and building mock-ups and doing some design work during slow downs at work. I'll have a donation link up eventually if any one wants to help cover the initial costs.
-----------------------------------------------------------------------------
CURRENT DEVELOPMENT STAGE: 1- INDUCTIVE CASE RESEARCH, see #1​
PLEASE KEEP AN EYE ON THIS POST (general updates) AND POST#3 (useful links and eventually tutorial)
:good:KEEP DISCUSSION AROUND THE FOLLOWING DESIGN INTENTIONS/ ABOVE DEVELOPMENT STAGE:good:
Design Intents are as follows:
1) A case for housing the inductive coil/wiring
This just requires compatible cases with necessary clearance for the inductive coil and wiring to the male micro usb. Cases with oversized bumpers would be best since they will keep drops from damaging the micro usb plug that will be sticking out of the bottom of the phone. This may not be ideal so if anyone is decent and making plastic molds maybe we could come up with an attachment to a case.
2)NO Hard wiring inside/to the phone
This involves using low profile male mirco USB type B connectors, like this, and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The main design issue here is protecting the male connector to the phone. Suggest usb connectors, wiring, how to boost the amperage, does the palm pre coil protect from over voltage, etc.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. Others are encouraged to come up/share your solutions as well! This should be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders out there keep that possible issue in mind.
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Current Progress: CASE​Alright I have the cases in hand! I got three of them in the mail and will be tearing these apart this weekend. The pucks (touchstone bases) should be here sometime next week.
I'm also looking at the following cases
Ballistic
Ballistic 2
Clear S Case
The ballistic I am hoping will give clearance for the micro usb. They will be a bit heavier though... we'll see.
I going to order 2 cases for starters, what should they be?

Regarding the thread, this would be hardware development which i believe belongs in the general section. As for the idea, it seems like as long as its not too bulky most users wouldn't mind if it extended battery life substantially like 24 hours or more. Could make you rich with over 9.million sgsIII owners. But Im pretty sure there are already many types of chargers on the market so unless i missed something perhaps you should submit this to a patent office so no one steals the idea or design. Just my two cents dinner no one else has posted. But ya not software development so I would move three thread before you get flamed too bad.

No flaming allowed.

Design Intents are as follows:
1) A case based solution, the ET4G is too damn thin!
This is just require compatible cases with necessary clearance and materials
that are least obstructive to the magnetic field.
2)NO Hard wiring inside/to the phone
This involves ordering male mirco USB type B connectors and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The only issue here is protecting the male connector to the phone. I've some ideas for this but will be very dependent on the case we use.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. This will be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders I'll keep that possible issue in mind.

Either way let me know because I'm going to start order parts and doing some design work during slow downs at work.

I'm game! I tried doing it myself but I could only find the one spot on the USB plug to hook up to. I opted but to do it because there was some massive dismantling and soldering I would've had to do. I've still got the parts ready for when someone smarter than me figures out an easier way to do it though!

Just a thought.
What would be the charging time using touchstone/conductive charging; or in other words, what would be the output voltage/current provided to the phone. It takes a while on regular chargers to charge the phone compared to HTC phones.

haha I actually did this too my I500. Literally car kit and everything. Even had it play music through Bluetooth. except I hated cases on that phone so I hardwired it. looked so much sexier. But the case is easier. Built like that too just didn't have the car cradle

How much would this be for a car charger and home charger wireless
Sent from my SPH-D710 using xda premium

I have 2 palm touchstones, 2 old fried pre & pre2, and 2 phone backs for the touchstone charger to integrate with the phone..
I would absolutely love to know how to integrate the "guts" of the battery cover with the needed parts into the e4gt innards to make the wireless charger .. but I'm not sure how yet.. :/ I will keep reading and post here if I get it working..
I assume that the physical connection is totally possible but the OS will most likely need to be able to control voltage and jazz so I'm not sure what would be needed for that part..

Thanks for all the interest and offers for assistance. Being that its my friend's birthday as well as my own on top of fathers day weekend I won't start any design research until Monday.
I have ordered some parts which should be here late next week. I am still trying to find a source for some type B micro USB plugs. Guess I'll shoud stop throwing away those electronic component magazines. I did a quick search and found some but they were $6.50 each with $10 shipping. If any of you have a source for these let me know. Hell you can send me spare cables and I'll deconstruct them if I have to, but that's not very fun.
When I get on my PC I'll add a poll to see where you all would like this topic to be. Then I'll ask you how do I move it

Lets do it!
I actually got the touchstone and pre back and ripped out the inductive charging circuit just for this (I actually got it for my evo, but I upgraded before I had the chance to follow the evo guide). I'm excited for this!
Anyway - some heads up - the E4GT is MUCH heavier and bigger than the pre. Don't expect it to stay firmly attached. It will stay okay, but you need a really thin back face of the case. You may also try replacing the thin magnets with thicker rare earths. I actually got it under the stock cover okay, and that worked decently, but no good way to attach it. That's where I quit (after thinking about soldering to the board, but not having a good place on the USB connector without taking the phone all of the way apart. I also didn't fins another point on the board to solder to (like the charging circuit), although I'm sure it's there somewhere.
Also, you need to mount the inductive charging circuit a little low because the phone is so long that it will hit the table and not mount properly if you put it in the middle. Furthermore, be ware that if you add a connector to the USB port, this will exacerbate this problem, perhaps to the point of requiring landscape or stronger magnets.
The USB connector you want are available at a number of places. Ebay has some cheap micro usb adapters (including right angle) that you might play with. If you just want the connector itself, it will likely be more expensive, but I suggest checking mouser or digikey.
Good luck! This will be AWESOME!

Disassemble and reassemble of galaxy nexus :)

I have a few pictures of my galaxy nexus broken down if anyone would like to ask me questions on how and where things go they can. I actually find this phone to be very easy to get apart and if careful can be reassembled in 15 minutes. I was actually replacing my speaker with some old parts I bought off a guy. No more crackling! Anyways in the process grabbed some pics
U can see the first three are the screen bottom speaker, main board, vibe, etc. The last pic she's all back together

Somehow I imagined a picture of me tearing down a smartphone where I was photoshopped out and replaced with a picture of a dog in a labcoat saying: "I have no idea what I'm doing"

Yep this phone is one of the easiest ive worked with. had to open mine to replace the earpiece. the only thing to take care of is the volume ribbon and vibrator wires, they can snap off really easily.

Yes sir....I just stuck a razor blade between them and the housing and they come right off connected to a gel like glue. This was good because sticking them back in place they actually stayed. U also have to remove the vibrator motor and the long black wire running down alongside the battery compartment (it has connectors on each end) then of course your two ribbon connectors for main board then one ribbon connector for bottom speaker. Didn't touch cams no need to.....very very easy job in fact it was to easy.

I have to replace my USB board (my USB port was damaged) and I am a newbie doing this kind of service myself. I bought it on ebay:

Yes for sure...but if u do not feel safe doing it then take it in. I know to get to the usb the whole speaker and housing comes off of the top of that. Which is one screw then a ribbon fairly easy....then u just work something thin in between that and housing like a guitar pic or Mac card. I would go with guitar pic tho so u don't mess the corners of your card up. I know that once the speaker portion is off u see in my first pic the USB I think has its on board. I truthfully did not take that portion of it out thought it was kind of pointless. If u need help I will assist u if u decide to do it yourself

Thats pretty neat man, do you know where the GPS chip is?
I replaced my back cover and apparently I damaged the GPS chip cause I have NO gps lock, software side its ruled out (I flashed many diff ROMS, kernels and Radios and it used to work well before I opened up my Gnex)
Thank you.

where is the VZ LTE radio? maybe i can swap mine out for one that doesnt cause signal drops.

The battery cover? Hmmmm. I am pretty sure the GPS chip is on the opposite side of motherboard. Looking at ifixit photos it says right by rear camera on the opposite side of motherboard.
Edit...also if u look at first pic in my pictures look on right side of battery compartment . See the black wire with the connectors on each end? I wonder if the connector closest to bottom came loose or has something to do with it

Thanks, appreciate your time.
I checked out ifixit, thinking that in the process of removing the cover I could of hit the GPS chip or something, but since you pointed out that its on the opposite side of the motherboard that's not a possibility. Since I have not removed the mother board.
I have not opened it again, afraid of ruining something else.
But I guess I will have to in order to check the wire you speak about.
Salutations

I sent my phone in for repair to Samsung via Expansys for a bad external speaker. Back when it went bad, phone was too new to have all parts available as spares on the net plus the phone was still under warranty so I send it back to Samsung via Expansys-usa. But what I think happened is that Expansys didn't send it to Samsung and repaired it inhouse. I can say that because all screws inside the phone had chewed up heads and the repair didn't look good however the external speaker was working. First thing I found out that external volume rocker was not working anymore. So I send it back again to Expansys and I just received it back today with a note saying that the volume rocker ribbon pins have come away from the main board and taken the pin with them.
Bottom line is that they didn't repair the phone. Any ideas on how I can get this fixed? Do I have to change the ribbon? if I want to do it myself or this sort of damage requires a new board?
Any ideas comments are appreciated.
Edit: Link to photo showing the pins that are separated from the board

Hi Sarni,
I accidentally snapped the ribbon (refer to attached pic, circled in red), and now my speaker is not working anymore. I guess that ribbon was for connecting the speaker and headphone jack? . What do you think i should do now, replace the whole piece?
I also intend to replace my damaged charge port, but not sure how to proceed for that.
Thanks,

Please help to Which antenna belong these pins

Hello guys,
I disassembled my One X today to fix the wifi fault, I fixed it and now the signal strengh is excellent, but when opening it I damaged 2 pins which I don't know to what antenna they belong.. Though I tested my phone after assembling, everything works good (wifi, gps, bluetooth, signal, 3g), so I don't know what are those pins/connectors, here are the said pins circled with red, please help me I need to know
Thanks in advance,

Could be NFC... Take a bus card, gym card or similar and try to read it.
I saw a pic describing the pins earlier today, lemme find it for you.

Thank you for the fast reply, I don't care about NFC I stored the pins and I'll solder them when I'll have time, for now I don't want to reopen it another time

anyone confirms that those pins are for NFC? because NFC is working like it should, but GPS is taking time to lock, and it locks to 6 satellites Max, no way to get more :/ are they GPS pins?

According to my photo, they are not mobile signal ,WiFi or GPS.
What's left then??
And how did you damage them? Totally snapped off or bent a little?

When I inserted a bit of plastic on the left side, I damaged the pins, they was completely removed! I have them and I can solder them but I don't want to solder anything because I'm willing to sell it to get the One, and scared to damage another thing when soldering..

Might be something to do with the pogo(docking) pins, pictured here

Might be; but there's also a traditional flex cable for the pogo pins.

[Q] Issues with replacement screen

Hello, I recently purchased (from Asus) and installed a replacement LCD + digitizer on my N7. It went together easier than expected and I was happy with the results until I noticed that while multi-touching the screen it wigs out a bit. I cannot play Minecraft PE and move and look around at the same time for example. I cannot zoom in or out on pics without the picture jumping around like in a seizure like state for another example. Any ideas? I don't want to have to open it again but I will do what is necessary to fix this issue.
Thank you.

Asus don't sell parts to consumers so I don't know where you got it. Sounds like the part is faulty but check everything's connected properly and no damage to any of the flex ribbons.

Im not exactly saying your mistaken. I just question why asus would need to use amazon to sell parts? I have bought plenty of screens from amazon. One thing that is relatively certain, aftermarket parts. That doesn't mean bad in most cases just not oem. There is a touchscreen fix in either general or this Q&a. You may want to give that a try.

Maybe it only looked like easy and something went wrong when assembling it by yourself.

I am willing to admit that I did something wrong I've got a friend who is more experienced at these things who is going to take a look. As far as the screen goes the seller was marked as Asus. Thanks for all the insight so far I looked up more dead spot issues with the N7 and it seems like I'm not the only one.

How does thermal paste make an adhesive? And why do you need that for a cable connection? A thermal paste transfers heat from one surface to another. A cable connection generates no heat. Also, some thermal pastes conduct current. If you smear an amount of such stuff on the connector, you might cause the pins to short. 'm confused.

What I'm Looking for is an adhesive for the ribbon cable connevtion . one of the articles above explains the dead spot issue I am having. Sorry for the dumb question I don't have a lot of experience working inside of things like this but I figured the tablet was trash if I couldn't fix it anyways so I might as well give it shot for the experience.

Modifying Parts

Deleted, lack of help, already achieved.

General though I forgot to add if that project could be real, it would teach Samsung and att a great lesson and someone would sell these parts and make money out of them.

Sounds like it's more trouble than it's worth.

It's not like a car where you can unscrew a few screws and exchange the part for a new one. This device has thousands of microscopic soldered components, so unless you have very advanced technology, you are not going to replace core components.

I see something like this happening for laptops first.. and the reason they don't do it for them now (with very few exceptions) is because most everything is integrated into the mainboard.
Have you ever tried to solder an smd resistor onto a pcb with just your basic general use soldering iron? It's damn near impossible without putting too much heat on the resistor or soldering the pad next to it also.
Everything is so tiny and cramped in laptops, imagine how much more tight things get in a cell phone. There was one (or maybe a couple) mfgrs that are doing plug and play build a phone. Think hi tec Legos but in general. I gonna guess that the phone would have to be designed for this from the ground up.
Good thought.. but probably a few years ahead of its time.

Thanks for your insight. I was asking because I have done a lot of reverse engineering and a little 3D printing. I have seen couple of project Ara videos and it doesn't seem impossible.
I have a note 3 that I use for testing. I will play around with it and some other components. If I had any luck to start with, it would be a mini step forward

At best what you might find is some internal only interface like jtag or something that you can modify what's loaded on the eeprom and spi flash. Really big if on that.
