[HMOD]Wireless Charging for home and on the go - Samsung Epic 4G Touch

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'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

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!

Galaxy S2 Inductive Charging IN PROGRESS

So I think it's finally time to get this going. I'm going to be taking apart and installing Touchstone wireless charging into my Hercules Galaxy S2. The parts are on order (I was going to do this with a PowerMat charger I had lying around but then I found out it's not compatible with the cheaper touchstone system so I ordered that instead). Should be getting pictures and guide (maybe video too) by the end of next weekend. Stay tuned.
This will be awesome!
Pretty cool thing.
Someone else did it with a touchstone dock. The microUSB port is kind of blocked, here but the kid who made it has another version of it, as well, with hidden cables and whatnot.

I saw that. The idea with this mod is to be similar to his Galaxy S mod that has the free USB port. I'm not a fan of wires sticking out. Should be getting the Touchstone gear tomorrow and then the foil on Friday (copper foil). I'll do a bigger write-up when it's complete including materials and directions. As far as I know, nobody has done this yet with the GSII, which is why I want to do this and kind of add on to what the other guy did but for this newest generation
This is gonna be awesome.
I nearly broke my Vibrant when I did that last year. I'm not going through that experience again.
On a bright note: I now know how to completely take it apart and piece it back together in 5 minutes.
very excited for this! looking forward to the results/write-up and maybe if i have the balls ill give it a go myself . Good luck.

Question, Could the TouchStone interfere with the NFC communications ?
had no idea there was no support for our phones on this, i'm definitely interested as i dont like plugging and unplugging my charger all the time It'd be even more awesome to intuitively convert this into a wireless car charger haha
What would be really awesome is if there was a way to not only have wireless charging but have like a 5 for radius for the charging as well that doesn't muck with the NFC

This was my first thought... would the induction field pump power into the NFC antennas and cause damage... but I'm not an engineer which is why I love the XDA community.
I dunno of it would mess with the NFC coil but I am thinking not unless it is "tunned" to the same frequency as the induction coil, them again on the other hand id that was true then we couldn't have our phones around ANY magnetic field. I would wager that the NFC coil may be grounded out already somehow, that is not to mention that it is "tunned" to a specific frequency as well...... justa thought

Induction Mod completed
I attempted the induction mod and was successful. I soldered a wire to the same pin as shown in the video for the Galaxy S. I need to clean it up with copper foil tape but it is functional. Putting the battery cover back is difficult because of the limited space between the battery and cover. I didn't take any pictures but if anyone has questions I would be happy to assist.
Can you take some pictures so that we can see and how snug was the battery cover? Does it interfere with the NFC?. Right now I an rocking the nexus extended battery and it's cramped to say the least

My only camera is my phone so I can't take any pictures. I have not tried the NFC function on my phone but I think the coil may interfere. As far as the battery cover is concerned, there is not enough space if you are using a larger battery.

What are you using for your pogo pin contacts?

Happened to come across this business card holder in the store and it holds the Galaxy Nexus perfectly. The mesh spacing is also almost the same width as the pogo connections, so I'm looking into modding this into a pogo dock.
http://www.officemax.com/office-furniture/desk-accessories-organizers/product-prod2980161
Just wondering what everyone has been using for their pogo pin contacts? I've seen mentions of guitar string, push pins, and screws from other threads here. I plan to solder the ends of the USB wires to the contact, then hot glue them in place on the holder (which also will insulate them from the mesh so I don't get any shorts).
I'm also thinking of making a slightly raised section on the right side that lines up with the power button so that I can push the phone down slightly to hit power, since I don't want the screen on constantly while in the dock.
you might want to check here for info on enabling the middle pin to get AC charge and Desk/Car mode.
As for docks, I'm using a case, so i'm going to start work this week on moding my case to make pins accessible from the outside.
Pogo pins from yokowo, lined up with the official stand/extra battery charger.
Is there anyway to get these in the US? I'm not near their 2 stores here and I don't see anything about ordering online. I'd prefer to use something like this that's actually made for it rather than have to ghetto rig something

I think ghetto rigging something is the only way to go with the pogo contacts. There arent many accessories that make use of the contacts and dont think Samsung or anyone else is going to be coming out with anything new as newer phones come out. I hope as it seems like it is an awesome way to charge the device but think you have to check out the DIY sticky thread at the top of this forum to get better ideas. GL

UART Output

Back in the days when I was more adventurous with my Infuse 4g, I put together a little project board that allows me to specify resistances between pins 4 and 5 of a Micro-B USB cable. This allowed me to force my phone into Car Dock mode, or act as a USB JIG (for Triangle-Away purposes), or even connect to the phone using UART. I have a TTL 3.3v level conversion on the other end (a nice little FTDI breakout board that provides a USB serial port), and that makes it simple to capture the output of UART while the phone boots. I’ve used this board on my Infuse, my Galaxy S2, and now my new Galaxy S4.
To get it to work this time, I had to connect the RxD, TxD, VCC and GND wires up like usual to the FTDI breakout board, but I had to attach the 619k resistance at a specific timing. Here’s the order:
Unplug battery
Attach MicroB cable to phone
Attach the 4 wires above (easy for me, with dip switches for each)
Attach battery
Start Putty
Attach 619k resistance between 4th/5th pins.
Watch the magic
Attached is the UART output from this. Many thanks to AdamOutler and his help with the previous generations of Samsung devices. Hope this somehow helps in the efforts to obtain root. Let me know if there's anything special you'd like me to try.
Just tried my jig on the S4, and it works to put the phone in download mode.

I've been trying various resistances, and I can't seem to get to an SBL prompt. I'm wondering if this is because the bootloader is locked? If anyone has different results, please let us know how you did it. (thanks)
Any way I could get someone with some wiring experience to check out what we've got going on with the Samsung Infuse car dock on this thread? Trying to figure out why the Infuse car dock worked on the Skyrocket and SIII for me personally, but not the S4 - won't put it in car dock mode and won't charge the device.... if someone knew where the wires were supposed to be run, I have a spare base with a plug on it that's not attached to the mount that I can hack up, provided this isn't something too intense for me to get involved in! I can do a good bit of customizing when it comes to cars and car electronics, but I don't have all the cool tools it sounds like some of you have!
Thanks in advance for any insight you can bring to this discussion!

I set my jig-board to 619k exactly and provided it with vcc5v and a ground, and it does not charge and does not give car dock mode at all. For older Samsung devices, I always referenced:

However, it seems the hardware might have changed? The older handsets have the fsa9480 ... perhaps one of our hardware-oriented devs could tell us what the S4 has inside? Might point us in the right direction to get the same list of modes/resistances ...

Here's what one of the guys from iBolt has to say about the dock, collected from two threads regarding the Infuse dock:
MikaelPe said:
The Infuse Dock can't be used with the Galaxy S4 no matter what. This has to do with the fact that Samsung has changed the pin-out configuration when moving to the "new platform" so there's no technical way (to the best of our knowledge) to get it to charge or to start the car-mode. Not sure if this helps?

MikaelPe said:
Kryptos, as you probably saw in my reply on the other thread I unfortunately think the Infuse Dock is dead. Samsung have changed both the firmware and the pin-out so it neither charges nor is the traditional car-mode present anymore. As Samsung is not building their own OEM car dock it was probably not on the "checklist" so they simply skipped integrating the functionality. We've obviously figured out a solution and we are hard at work bringing a bunch of developers with us so they make their apps compatible with our Dock. We all can benefit from not only "DockMode" (as we simply call it henceforth) and the nice "aux-out" through microUSB, that is in my opinion a much bigger deal then anything they presented as "new feature" when introducing the S4. Hope this answers helps?

So I ended up ordered the iBolt xProDock from Amazon, don't worry about replying to the PM I send you Aou since we really don't have any testing to do on the iBolt or modifying to do on the Infuse dock - it is dead and I don't think I'm prepared to even try and revive it!
Sorry to "necro" but I need more info on this. If you connect the 619K resistor before power-on won't it work? What are the settings for baudrate, error checking etc.??

Who's Interested in a Auto Dock?

I'm designing a dock for the N7v2 for use in a car. It will have Qi wireless charging and Bluetooth audio receiver, with a standard 3.5mm audio output. It should be compatible with most cases.
I am also currently designing a mounting method that should be close to universal between different cars, and should not fall off like most other docks in the market.
I designed one for the N7v1 using the Pogo pins, and I can never go back to not having a dock for my tablet in my car. It's amazing the difference it made for me.
I want to know a couple things.Please reply with the following template:
1. Would you want a dock like this?
2. How much do you expect to pay for it?
Thank you everyone, in advance!

Sounds like a great idea. Do you have any links showing your work with N7v1? Heck, I may be interested in that version since the v1 tablet can be had for cheap these days and is more than capable for the limited functions needed in a car. At any rate:
1. yes, would be interested
2. no idea what a fair price would be, but $50-$100 seems like a fair ballpark
I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?
The wireless car mount/charger iterations for the Nexus 4 were a failure, I recall.

I've attached 4 pictures of the dock I made for the first Nexus 7. You'll notice that it inst exactly a dock you can put in just any car. I realized I made a little too rugged... and big!

I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?
The wireless car mount/charger iterations for the Nexus 4 were a failure, I recall.

Well, that's why I don't leave the tablet in the car, I keep it with me. While I'm in the car, if it's hot out I will have the A/C on anyways, so heat has not been an issue.
Most of my broken devices are dead because the USB port broke because of wear and tear. One of the points of this dock is to reduce that. Plugging in a device everytime I get in the car is partly to blame for such failures. I would have used Pogo Pins, like with the first Nexus 7, but they don't exist on the second.
Shared app developing ideas
Hey everyone,
my name is joseph and i am new to this website. I am also new to the whole rooting phones as well as i am learning the basics of computer science-- os, rom, ram, eprom, android, custom roms.....etc.
I honestly have no idea what i am looking to read and study up on so if you have any ideas than please let me know so i can educate myself. I end goal is to be a program developer.
Also i have an amazing ideas of a great new app. I have the layouts for the app but don't have the knowledge to build the app myself. If you are interested in learning more about my idea and possibly collaberate pleae let me know and we can possibly exchange numbers.
Another thing, i am an inventor and creator.

Look at active Brodit car mounts - say for a Nexus 4. There the device is supported and aligned as it glides onto or off the USB. There is no possibility of twisting or yawing.
I think your proposal maybe over-kill - simplest solutions are always best IMHO. A guy in the Nexus 4 forum came to no good end and had a lot of unhappy 'subscribers'. Just saying.

I would normally agree. I was hoping to make one that doesnt require a case to be removed to use. I designed my previous dock the way you describe (except it used the Pogo pins on the side), but I always had to remove the case and eventually the first case was showing signs of damage from being removed so often.
My hope is that the base platform of the dock I want to build will be compatible with multiple models of smartphones and tablets that are Qi capable. That'll require a lot more planning, but may be worth it.

Well if you're set on the route you've described; ... I see you've picked up on the Peltier pump in another thread. Credit me somewhere if you make it!
But I might consider an approach made by Philips in an Android Bluetooth Speaker and dock. The adjustment for USB and its placement on an edge, plus 180 degree rotation needed for some models, was catered for physically. A much cheaper approach which copes with tablets and phones!

I think I will use a Peltier pump. And yes, I'll make sure you get credit for that idea I'll mount the transmitting coil onto the cold side (probably with a layer of copper in between, we'll try several things) and have the hot side of the pump mounted to the aluminum/sheet metal of the back plate (probably with thermal paste as well). I'll have the pump on a simple thermostat. Good thing I have an EE helping me with this project
Hopefully the final product won't need a Peltier pump, but I will definitely have it in the prototype.

I haven't had very good experiences with using that type of dock The results of daily use tend to be USB ports that are stretched and loose. At least that's how it has been in my experience.

Don't forget to talk to your EE about eddy current loses in any conductors (copper, aluminium) you have nearby to your induction coil.
Interesting read, but with the cooler this is going to be a very expensive dock. Without it, look to Canada for your market.
I rigged up one for my Nexus 4 last Winter. Based on some testing, I used the most efficient charger I could find for that phone (the LG wcp-700). It worked very well... until late spring when the mercury broke 70. To make a long story short, I pulled it last month as the phone was getting too hot. This in a suv with a 4 liter v6 with plenty of air conditioning, front and rear.
Without the cooler, the tablet needs to be located directly in front of a vent, or even in moderate climates the unit will get hot enough to significantly reduce charging current.
One more thing to consider... the Nexus 7 is polarized vertically. This means that it is invisible in landscape orientation for anyone wearing polarized driving glasses, which I am willing to bet is a large percentage of your prospective market (tech savvy, auto enthusiasts). Most displays designed for vehicles are polarized at 45°, making this not such an issue.
While the tinkerer, software developer, and electronic geek in me wanted a fully integrated tablet in my truck, I soon came to the conclusion that it was simply not practical. What is really needed is a properly done appRadio, where a head unit can mirror the display of a mobile device (ideally wirelessly - miracast, etc.) with a control link set up to pass touches on the head unit back to the mobile device. We're about 30% there now, but a lack of standards, and major players wanting proprietary solutions is a problem.
I wish you much success with your endeavor, but just wanted to share my experience and feelings that this will not be all that marketable a product.
The problems you had with the nexus 4 does not necessarily effect the nexus 7. The nexus 4 was pretty terrible at wireless charging. I had a car setup with a qi charger with the lumia 920 and it worked great even in hot weather. I am not saying the nexus 7 will work, but it might.

What makes you say that? I ask as I have seen relatively similar performance with both the N7 and N4. The tricky thing about the N4 is that the coil is not centered in the vertical dimension, so for folks making the assumption that it is, there will be quite a bit of offset.

I say that because of all the issues people had with car docks. It also had issues with the dt-900 qi chargers when it shouldn't have. It heated up excessively with most chargers.
I wonder if there will be an Official dock that lets you:
1. Charge
2. Expand TV HDMI out
3. USB port for Hard drive access
I really want the Nexus & FHD to be a Home entertainment player...may be a remote/ Or Kinect like gesture control app built in with the dock
Hope this comes true...it will be the best Combo for a home unit!

Docking Station

Hi,
so soon my nexus will be here and after over 6 years with iPhone I'm moving to try android.
one think i always loved about my iphone is the docking station, makes life better and easier.
now with the iphone its very easy to find docking station that fit 100% right, and then i dont have to worry about damage to the charging port, the phone is held up very tight and i never had any problem.
on the android camp its harder to find phone specific accessories so heres what i manage to find:
im looking for a cheap solution but can pay a little more if its really worth it
cheap:
http://www.ebay.com/itm/Micro-USB-D...AU_MobilePhoneAccessories&hash=item2ecab22c6d
expensive:
http://www.ebay.com/itm/Universal-M...Phone_PDA_Cables_Adapters&hash=item43c158ab0c
the expensive one at least comes with a cable, and heres a video i found that shows that this product might be a better choice:
http://www.youtube.com/watch?v=wTyGmNTh6iA
i just dont want the device to wobble freely hanging only by the usb connector.
i also hear that micro usb is much weaker then apple connectors so im a bit worried.
any1 have any experince with such products? what do u think? am i risking damage to my usb port? thanks.

IMHO ... yes, you are risking damaging the port. I personally wouldn't even consider using one as I've gone through a bunch of phones that the Micro-USB eventually stopped working properly. The Nexus one was notorious for that problem as have been quite a few other devices. Micro-USB just doesn't hold up over time.
Now, back to your problem. One thing the Nexus 5 has over the iPhone is Qi Wireless charging. So, might I suggest stop thinking in terms of how you would plugin in your iPhone to charge it, and to sync it with iTunes. All of this can be done using apps that sync wirelessly (iSyncr etc) and a good Qi charger.
Here's a good starting point for a "dock" like standing position while your N5 charges:

It's important for you to note the orientation of the Micro USB port on the phone. On nexus devices reversed compared to the samsung phones those docks are for. I own the dock on the first link. It will not work with the Nexus.
You need one that's pin-side facing you. Unless you want the phone facing away from you
It's an annoying aspect of the Micro USB standard -- when it comes to direction, there is no standard.
DIY: Not ideal because it doesn't LOOK great but does WORK great. I bought the dock from that first link for my S3 and because of its 'universal'ness it was extremely wobbly, putting much undue strain on the port. I stuck a couple wads of Sugru down on the dock and behind the connector (where the phones back would rest) and stuck my phone in. When it dried after 30 minutes I had a perfect custom fit. Looked like **** though. Function over form in this case.

this...
but this is also a relatively new thing as the Nexus 4 was the "standard" way that everyone is used to (small side up where the Nexus 5 flipped it to small side down)
For charging, I would recomend the Google's wireless charger: https://play.google.com/store/devices/details/Nexus_Wireless_Charger?id=nexus_wireless_charger. As for syncing, what kind of things are you going to sync from your computer to your phone? On the android side the majority of things can/are synced over wifi or cloud services.

Thanks for all the answers...
I didn't think about orientation lol, i forgot about this issue.. so docking stations seems meh ATM
about wireless chargers... quite expensive IMO and i always fear that since the phone is not being held tightly it might fall and break.
i put my phone on a nightstand near my bed so accidents in the dark could happen, and i also like it when the phone is standing so i can see the screen without picking it up.
so that limits the range of wireless chargers i can use.
syncing is not a problem btw.
good thing i asked here.. i almost bought one of those. i guess ill try to find wireless one that suites me.
thanks again!

Google is your friend as usual, Kidigi are about to launch a Nexus 5 specific dock which is more substantial than the one you were looking at.
