HI all,
After being frustrated in finding the perfect car mount with fast wireless charging, I decided to make my own. I already own an Anker car mount (https://www.amazon.com/gp/product/B01HNSIHCO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 and decided to use that instead.
I purchased a fast wireless charger from Amazon https://www.amazon.com/gp/product/B01E1EIAQQ/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 for $6.99, and promptly took it apart.

All those screws...
A few more hiding here
But wait, there's more!
And finally, we get to the guts...
Even though the desciption says 1 coil, there are in fact 2, so you can rest the phone in landscape or stand it up
The IC board, secured by 4 screws
Status LED, covered by a piece of plastic that pops off, and secured by two more screws
And here it comes off
The other side of the IC board.
And the back of the QI coils. This adhesive is fairly strong, so I protected it with thick plastic sheeting, and reused it to attach it to my car mount. Note the dangling two wires - that's attached to the status LED, which you can route to wherever you like. I just removed it for simplicity's sake, since the phone indicates when it's charging. The light also turns off after a couple of minutes (to prevent distraction when trying to sleep, so not really useful as an indicator of charging).
This is it rough mounted
I don't have final pics yet, will put them up soon. I didn't like how the IC board was just hanging out, so I designed a 3d-printable box to enclose it. I removed the LED status light, because I didn't need it, and have it up and running!
Mounting it, you want the top-most coil to be right around the midpoint of your S8+, seems like this is the sweet spot. It consistently charges at around 870mA, though it does fluctuate. The most important thing is that it will charge 870mA under load (google maps, pandora, and 100% brightness during daytime driving). Is it as fast as the usb-c cable and a fast charger? No, but it will save wear and tear, and I can just put the phone in the dock and go, and not have to hunt around for the cable. Note, you will need a fast car charger in order for this to work. I use this one that I ordered from Amazon https://www.amazon.com/Samsung-Adaptive-Charging-Charger-Adapter/dp/B00TZ9PO6M/ref=sr_1_28?ie=UTF8&qid=1502600122&sr=8-28, though you could probably use any adaptive fast charger compatible with the Samsung S8.
I will probably cover the Qi coils with electrical tape to reduce the chance of damage from friction, and will put an NFC tag to automate routine things I do when I get in the car (currently I'm using an old NFC-embedded transit pass with the app Trigger - shuts off wifi and auto-launches Google Maps. Still trying to figure out how to auto-enable low power mode, since I don't need push notifications for many things while I'm driving).

Let me know if you have any questions. For 6.99 + tax + some electrical tape, you can build your own fast wireless charging mount with your existing car mount.
good start.
If you are using a case you could consider making it magnetic:

True, but I figured I already had a mount that I liked, and this makes it cheaper for me. For many others, they may already have a mount that they like, and this would add fast wireless charging to it.
If in the future I need to replace my mount, I may go the magnetic route. It's cool to just hold it up and have it pulled onto the mount and centered.

Beware of metal close to induction charge....
I made a induction charge test with magnetic holder forgotting induction heat metal....result: melted the cover.

This is my variation of a 3 pin pogo charging car dock.
I noticed the spacing of the SD sliding contact prongs from an old multicard reader were very close to the spacing of our 3 pins on the Gnex.
So I took it apart, pryed off the reader, and bent the prongs up slightly to make contact. I filed off as much extra plastic as possible. I snipped & striped a USB cable and soldered the red and black wires to the respective prongs.
Im in Norway, so I didn't have access to a VZW dumb dock to make this nice and clean. Instead I used a universal car mount to clamp down on the bottom half of a clamshell gnex case for repeatable contact. I put an NFC tag in the mount to trigger NFC Retag app to launch Torque app and enable bluetooth communication with the ELM 327 ODB2 bluetooth transmitter. These are cheap, and I highly recommend them to anyone interested in car tuning.
My next step is to flash the full amp pogo charging kernel, and actually mount this in the car when my wife gets back with it.

A shout out to elleshoo for the inspiration. Geaux Tigers!
ok, reuploaded pictures that fit on the screen now.
Nice, this looks simple enough. I'll have to try this out with my dock.
If you are rooted you can charge much faster than the default 500amp limit on the pogo pins if you use a kernel with chads fast charge mod(like Franco kernel)

Definitely on my to do list. Right after mounting in the car and educating myself on flashing kernels...

Nice mod! And Geaux Tigers! I'm actually attending LSU as an undergrad right now!
Friction fit mounted to the swivel AC vents using an IKEA L bracket cover.
This allows easy reorientation at the cost of 1 blocked vent.
Running off a kensington usb plug with D+D- soldered.
Sorry for bad pics, my good camera was at home.
Gonna rode test on the drive home today, I know all the parts work seperate, so it should work together.
Just a little worried about the vibration pivoting the vent b/c phone is not perfectly balanced.

Got the force charge Franco Kernel going, and confirmed it in the pogo charger.
It takes few seconds to recognize its docked now, but it does go full AC.

Its a crappy rocketfish from bestbuy, I linked to it in first post. but I wouldn't recommend using it as a case, its nearly impossible to get off and leaves weird marks.
Here is the charge SS from my drive. I did get a batt lvl increase with blue tooth, gps, syncs and light browsing in use. So it works.
Did you ever get that fast charge working thru the pogo pins?
Yes, it worked beautifully on the fast charge kernel from faux and Franco. Im m the JB builds now , waiting for that feature again. It makes a big difference.
Hello Guys!
First of all, sorry for my English, it is not my native language.
After a lot of reading about modding the Galaxy Nexus in order to add inductive (i.e. wireless) charging capability, and seeing that most of the mods around required opening the device, I decided to make my own flavour of this mod. So here it is, with some photos and a small tutorial.
I have used the usual Palm Pre Touchstone combo, so there is nothing new here.
However, I decided to use the pogo pins for the dock station to connect the charging coil to the device, and have added the coil on a hard cover. Lastly, instead of copper wire, I used a thin self-adhesive copper tape.
Here is the cover:

}
I got it from eBay for a few dollars.
First,from the Palm Pre cover I took out the coil with the charging circuit and the magnets, they are just glued below an adhesive. Use a heat gun or a hair dryer to soften the glue and a knife or something to pry it off. Then I have aligned the magnets on the cover with the help of the Touchstone dock, and superglued them.
Next step: I aligned the coil with the magnets the same way it was on the original Palm cover, glued it with double sided adhesive tape and added a few straps of of insulating tape (it's a high temperature insulating tape, which is perfect IMO because it's very thin and it can handle temperaturse up to 280C - so I could solder very close to it without melting it). :good:
To close the hole on the cover that let the pogo pins accessible I have put a piece of tape on the inside, then inserted the phone in the cover, and lastly added a good amount of epoxy. Sorry, I don't have a photo of this step.
Then, when the epoxy had settled, I took out the soldering iron.
I put two pieces of copper tape, as in the photo below, then I tinned the contacts on the coil and the copper tape, and lastly used two other small pieces of copper tape to bridge the contact and the copper. [See below] You could probably bend the tape at 90° flipping the adhesive side up, that's up to your taste. This way it's possible keep the solder joint very thin and neat.
Please notice, this image represent the first alpha version of the mod, I had to change a few details on the go and after some trial and error.
At first my plan was not to do any mod on the phone at all, but after one hour of failures, I decided that the only feasible way to make a good contact was to rise the pogo pins with some small solder blobs, such as here:
You have to take your time, don't hurry. I put the phone on a side to expose the pins, then heated the iron to the max temp and let a small solder blob fall from the point of the tip to the pin.
This is how the cover looked like at the end of the process.
Some black spray paint to make it look more professional:
And now, how it looks:
The cover still fits well, because the thickness of the circuit is a couple of millimeters at most.
Thanks to my sister for helping me with the photos.
Yep! It's charging!
Please notice: the charging rate is NOT AC, but USB (thus, a lot slower). This only happens because the circuit does not communicate with the phone through the central pin (it would require a PIC or something else to transmit two timed pulses, which is in short not doable). You can override this with a kernel capable of fast USB charging (such as franco.kernel).
To the mods: if I have done something wrong, please tell me and I'll try to fix it.
I have not posted any link to the products I have used, because I'm not sure if I'm allowed to, however you can get most of that stuff from eBay (not sure about the high temperature adhesive tape).
What do you think about this mod?
Can you upload your pic to another pic uploader like photo bucket?
Done. I had used ImageShack just because it was the only photo uploader I was registered to.
After a week of testing I found out that the touchstone dock (at least mine) seems a bit picky about the charger it is connected to. I found out that the original Samsung 5V 1A charger works fine for charging at AC rate, but the USB data cable has a fatty microusb connector that doesn't fit in the touchstone dock unless you open it up and remove some plastic (not a big deal, just three screws). I also tested a 5v 0.7A travel charger (not original) and it does work only at USB rate; if you enable fast charging in the kernel the phone refuses to charge at all).
Sent from my Galaxy Nexus using xda premium
Touchstone only transmit around 400+mA iirc.
Btw this belongs in the Accessory sub forum
I've planned to do a charging time test between wired charging and wireless charging.
And I have also reported my thread to see if a mod can move it.
This is cool. Now with the Daydream settings its like having webOS 2.1.0 on the GNex! Nice work!
This is a review of Monoprice Car Mount Cradle with car charger for Note 2: http://www.monoprice.com/Product/Index?p_id=10259
Let me start first by mentioning this is Monoprice branded accessory. As soon as you take a closer look you will realize this is actually KiDiGi Car Mount Cradle with a much better car charger in a more attractive packaging and only for HALF of the price of the original KiDiGi. Yep, its only $23 for the whole package including 1A Monoprice coiled car charger with LED light. It looks like Monoprice is branching out in their product catalog and now you can take advantage of a deep discount offered to us as part of their volume purchases.
For those not familiar with original KiDiGi cradle, it offers a unique mount where you slide your phone in landscape position and hold it in place with a secure spring loaded flip latch at the top. The cutout on the back of the mount opens a view to your camera and a flash for those who like to use it as dashboard cam. Also, it has 90degree micro-usb connector built into the mount for easier charging of the phone. The main charging cable from your car outlet goes into the back of the mount where there is micro-usb port which then internally connects to that external charging cable with that angled connector. Although not rated at full 2A, a provided 1A charger/cable should be adequate to power up and to charge your phone during long trips. The mount cradle is connected to an adjustable mounting arm with a suction cup. With a universal ball joint connection you can rotate it 360 degrees, which also makes it compatible with other types of mounting arms that have receptacle for ball joint. Also, the mounting arm has a joint nut to adjust the angle of the arm for a further fine-tuning of cradle position. Unfortunately, the suction cup is a regular non-sticky material which means you can use it on a glass or a smooth flat surface. Most of the other car mount manufacturers switched to sticky suction cup to allow better attachment to textured surface. To compensate for that, you get a disk with a sticky 3M side to position on your dashboard surface, or as an alternative you can use any other mounting arm with a sticky suction cup but you need to find one that has a receptacle rather then ball part.
Now here is a few very important points. Even so the box says support of Car Mode, Note 2 doesn't support that. Also, its a bit misleading that product description says it support Note 2 with and without a case. There is a spacer insert which could be removed. In theory once you remove it you should be able to insert Note 2 with a case. Unfortunate it will not work with anything as thick as Defender or Extended battery case, it will not even work with something like UAG or thin Case-Mate Tough cases, and it did not work for me even with thin TPU case. Maybe it could work with something like ultra thin air case from Spigen, but I don't have one to test it out. But it works well with a naked Note 2 and supplied insert.
Overall, its a good value considering what you are getting, but you have to be aware that you will not be able to use Note 2 in the case and also with included suction cup have to mount it only to a flat/smooth surface. Other then these limitations which might be a deal breaker for some, this is a solid car mount with a quality built and unique design.
Here are the pictures.

After receiving my Nokia DT-910 charger and realising it would charge fine without a case, but wouldn't with a case, I was very annoyed. I always use a case, so want to charge it with one on. Well, this is XDA, and we make things work here, so this is a mod to get the charger to work with a case.
Heres how to get your phone to charge with a case on it.

The problem is that the charging coil in the stand itself is too low, and when a case is on, the phone is not aligned to the coil inside.
You will need to open the base and front of the charger using a screwdriver/case opener etc. to pry the sides open. You will now need to undo two screws that hole the front cover on that the phone stands against.
[/URL][/IMG]
Once undone, pull the cover off, it will take a fair bit of force to do.
[/URL][/IMG]
Once inside, CAREFULLY pry the coil off the back of the charger (its stuck on with adhesive film) .. I accidentally cracked the ceramic backing of the coil, but it didn't break the charging circuit luckily and still works.
[/URL][/IMG]
Once the coil is off, chop some of the plastic that sits above the coil off.
[/URL][/IMG]
With the extra unnecessary plastic gone, you can move the coil up higher. There will be enough length on the cables, obviously don't stretch them too far or they will break.
I super glued the coil in place as the adhesive was a one use only type, let it dry, then put the whole thing back together.

Now i can charge my nexus 5 with a case on this charger
The really interesting part is that I have an energizer charging mat as well, and the nokia charger is far stronger than this. The Nokia will charge with thicker cases now. I can charge my nexus with this tough case, which is pretty thick.
[/URL][/IMG]
[/URL][/IMG]
I am also able to charge my nexus 4 with the thickest case i have, the Ballistic Sg, which i think is absolutely amazing, as none of my thicker cases charge on the energizer.
[/URL][/IMG]
In case you don't know just how thick this case really is, here it is against my spigen ultra hybrid for the nexus 5.
[/URL][/IMG]
So for anyone that wants a thick case and wireless charging, this mod and charger are very much your friend
Hope i helped someone with this mod
Enjoy!
LOL, did exactly the same myself yesterday, including cracking the ceramic, saved me posting it
Only amend I would make to your how to is undo all for screws in the base so the whole backrest detachs from the base and it is then quite easy to split the two halves to get to the coil.

Thats a good idea great minds think alike i guess
I'm fairly sure mines not getting as hot now
mod failed
hi there
thanks for the detailed instructions, just what I needed to use my lumia 1520 with the same black/blue type cover you use.
used great caution not to tear the wires and even managed to get the ceramic charging plate off without breaking it. relocated the plate as far up as wires would allow, however now it wouldn't charge at all although a computer guy I'm not an electronics engineer so I'm at a loss
as to what to check before tossing the thing. any ideas welcome!
cheers,

Hello. I have put together a simple way of making a car dock that is both magnetic and wireless charging. I made these docks using parts from Amazon, and the design is strong enough to hold and charge my phone through a pretty thick case. I'm posting this thread to show off what I have made, and to gauge people's interest in these car docks.
Since these don't seem to really exist on the market yet, I'm also considering refining the design and possibly collaborating with someone to mass produce and sell these docks. I refined the design so they are simple as possible to make, and can post a tutorial if people are interested.
Here are the products I used. Total cost under $50:
DigiYes® USB POWERQI Qi Wireless Charger
10 Neodymium Magnets 1/2 x 1/8 inch Disc N48
Aduro U-GRIP PLUS Universal Car Mount
So far I have made three mounts while experimenting with the fabrication process. The first one actually used a peanut butter jar lid and 10 magnets to hold my phone without any support (no pictures of this one). It was functional, but ugly as sin. Subsequent mounts I used the original casing from the charging coil, and simplified the process and cost/strength of magnets by adding a base support. Here are the results:

Not bad for a little bit of drilling and super glue (which I always make a mess of). Because of the way I came across parts, I only used a single "grip" as the base for resting the phone, however using both grips for a wider base might feel better when docking the phone. It's also possible to use even stronger N52 magnets and skip the base altogether, to give your phone the effect of "floating" on the dock.
The drilled holes are 1/2" and have to be close together as possible (without overlapping) in order to fit 4 magnets between the interior screws that hold the charging coil in place (inside the case, not visible). I used a rusty spade bit which was terrible and had a bad habit of tearing off more than it should. To make the mount look as clean as possible, I'd recommend using a more clean cutting bit, maybe something like this which will grind through the plastic without catching or tearing.
Well anyway I hope you guys like it and show some interest. If you have any further questions, please let me know. Thank you for reading!
I made something like this and it worked well. I should however be getting this in next week http://www.indiegogo.com/projects/the-air-dock
I'm excited for it. It's magnetic and also membrane grip and looks pretty nice.

Interesting position of magnets and size of them. How many mA you get charging? Also what case you using?

The charger is rated for 1A wireless charging, and that seems to be accurate. Is there a more accurate measurement I can pull from the phone? The case is Caseology Premium Shock Absorbent TPU Bumper Case and it's pretty thick in the back. It picks up the wireless coil okay, but I would need stronger N52 magnets to hold it up without a base (which I thought I ordered, but accidentally got n48 instead).
