Nice work. Thanks for the pictures and the walk through. Would like to see some pictures in the car when you install it. Have you been able to find a 90 degree angle micro USB connector so you can possibly hide the USB cord? Looks nice though. The best one I have seen yet.
[Nexus 5 Accessories] primetimelive:
Great mod!

I was looking at the picture of the phone. Do you know how big the magnets/metal plates that are surrounding the charging coil? I want to do a similar mod, and I was thinking of getting magnets that are the same diameter as the ones on the phone itself.
[Nexus 5 Accessories] AndyCr15:
Great post. I'm really not the DIY type, so I might struggle sinking the magnets in, but I really want a magnetic car mount, so maybe I'll try...
[Nexus 5 Accessories] bradputt:

A couple of more pics from inside the car...

To answer questions:

I think the metal disks in the phone are 10 mm diameter. I believe that quarter Inch magnets would work fine.

I was planning to hardwire the USB cable but switched fuses are few and far between in my car. I used the last one for my radar detector. Maybe I'll vampire off of the cig lighter port that's already there.
[Nexus 5 Accessories] kidgenius:
BAsed on the FCC photos, the disks are 6mm in diameter.

They are between 36 and 37mm apart, at their centers.

Very nice job! I will build one of these attached to a RAM ball so I can use my existing mount. I much prefer the one handed operation. But I will build it sans charger.

But a word of caution... I built an in vehicle cradle out of a WCP700 last year about this time. Come Summer, it was unusable to charge the phone under heavy use (screen and GPS on). Battery temperatures just got too high. Unless you can mount it in a location where the A/C can directly blow on it for cooling, you will prematurely toast your battery. I think there is a very good reason why OEMs don't offer one of these fro their phones.
[Nexus 5 Accessories] themuskr:
How good do the magnets hold it? I don't want my phone flying off it if I hit a pothole
[Nexus 5 Accessories] Solutions Etcetera:
I am guessing 4 magnets will be plenty strong. Each of the half inchers are rated at 1.6 pounds. They might be too strong. I am going to go with 3/8" ones as that is the smallest forstner bit I have.

BTW, for those getting ready to do this... use a forstner bit in a drill (press). They will shave a perfectly clean, round indentation.

I think I am going to make my sans charger version out of a hockey puck.

[Nexus 5 Accessories] pedxing:
The magnets hold well but the key is using some sort of non slip coating. it won't hold without that. I used plastidip spray but there are a lot of things that would work.
[Nexus 5 Accessories] pedxing:
Totally. The owlpad I had for the n4 was horrible about this. So far the wcp300 is causing less heat (it's been 75 here recently) but full summer is a different story. One reason I wanted the connection to the mount to be reversible. Right now the ac isn't directly on the back but it does point up at it.
[Nexus 5 Accessories] primetimelive:
I wish I had a drill press.. :(
[Nexus 5 Accessories] pedxing:
Ha! Me too. I came this close to getting one just for this project but the wife was already giving me looks. :rolleyes:

Hahaha...

Hmm.. would something like this work if you just had a regular hand drill?

From this post in the other thread about a magnetic Nexus 5 Qi car charger:

http://xdaforums.com/showpost.php?p=47530130&postcount=220

It appears that you can disassemble the LG charger including the top plate.

Once dissembled, you can drill the top plate separately without having to worry about hitting the coil and electronics underneath.

You could drill through the entire top plate with a regular drill instead of using a drill press and the forstner bit.

Just glue in the magnets in the holes and reassemble the charger.

Hope this helps... plee3
[Nexus 5 Accessories] manxam:
I've used that exact "press" before and it's really sloppy laterally. You'd probably be no worse off drilling by hand while drinking a beer...YMMV :)
[Nexus 5 Accessories] stupidpig07:
Thanks for the thread, I got mine done too. The magnet I used is N52 5/16" x 1/16", which is not strong enough to hold the phone with just 4 in the charger, so I added another 4 to the slim case, which secure the phone even when the car over a big bump. I was added a much bigger (N52 5/8" x 1/8") magnet to the center of the charger, but somehow it cause the charger error and refuse to charge, so I remove it.
[Nexus 5 Accessories] chris220954:
How well does the phone hold when driving? I can imagine its fine if the suspension in the car are good.
[Nexus 5 Accessories] bluegizmo83:
Has anyone tried this setup on a N5 with a Spigen Slim Armor case? I really like the idea of making my own magnetic car dock/charger but I'm just not sure those 1/2" x 1/8" N42 magnets would be strong enough with the thickness of this case...
[Nexus 5 Accessories] XorZone:
1/2x1/8 works for me with similar case, but mine are n52.
[Nexus 5 Accessories] undercover:
It's fine. I did attach the lip at the bottom though, as it doesn't look bad and gives that extra stopping power.
[Nexus 5 Accessories] jkenny23:
Here's my car dock for my Nexus 4 (should fit Nexus 5 or other phones as well, as long as they're around 70mm or wider):

It uses these two:

Aduro U-GRIP+ http://www.amazon.com/gp/product/B008ALV0V4

Powerbot PB1020 http://www.amazon.com/gp/product/B00F6SQ1D6

I cut out the red grippy part that would have touched the back of the phone, cut out some of the blue grippy part from the back of the Qi charger, and cut out a small square out of the U-GRIP and roughed up the surface so I could glue the two together with JB-Weld.
[Nexus 5 Accessories] Mashr:
Appreciate all the info everyone's put into this thread with the designs of their chargers. My buddy and I just finished building our mounts.

We used a forstner bit to drill 4 holes in the top of the charger to glue in the magnets. Then attached 4 more magnets to the underside of the top plate of the charger. They magnetically stay attached to the top glued magnets while providing double the holding strength for the phone. Even though I could still screw the circuit board back on, when I snapped the charger back together it forced the magnets to push off axis a bit, enough to not be flush any more and cause less attraction with the phone. So I unsnapped it and just used electrical tape to keep the two charger pieces together.

But I do have a heating issue even though I placed the 4 magnets around the outer ring of the charge coil closest to the edge of the charger. I've only tested while docked on a 25 min car drive. Not sure what the phone or battery temp got to but it felt pretty hot. Though I was playing music over bluetooth, had maps (Waze) on and screen at 100% brightness. So not sure if it was that or a combination of all.

Also, if anyone's interested, I use e-Robot to automatically open Google Maps and keep screen on when connected to the wireless charger. It's a bit easier to configure than tasker. What are some good apps you guys are using to monitor battery temperature and current charging voltage? I'm currently using a DashClock.battery extension.
[Nexus 5 Accessories] premo15:
It's normal for the phone to get hot with maps, max brightness and bluetooth on while charging...that's been my experience with every phone, even when plugged in. And wireless charging runs a bit hotter than wired in general. If it gets to be a problem you might consider getting a mount that attaches to your ac vent so you can keep it cool.

What size and strength are your magnets? If they're at least 1/2" n45 then you may not need to double up on them. It's possible that they're conducting more heat if they are actually contacting the coil.

Battery monitor widget is good for monitoring temperature and charge/drain rate.

[Nexus 5 Accessories] Mashr:
Yes the vent mount idea is a good one except living in Canada, you tend to be blasting the heat 6 months of the year instead of the a/c outta those vents. So that would just make it worse. I'm also skeptical of those vent mounts- wonder if they do any damage to the fins of the vent eventually breaking them. That's alot of weight pulling on those fins.

I used N52 cylinder 8x2mm magnets so they're pretty small. Placed them as far to the outer edges of the charger as possible. I tested with just the top 4 magnets but it didn't feel strong enough to keep the phone attached if going over bumps in the car. So had to double up adding the extra 4 magnets behind. That did the trick but I still think I should have added more magnets around the ring. Maybe 8 instead of 4 because when you place the phone on it, you have to hit the "sweet spot" for ultimate magnetic attraction and stickyness. Either that or I just didn't glue them in the right spots to match the Nexus 5's magnet placement. And I'm not using a case.

I'll be going on a 2 hour drive tomorrow so I'm going to unplug the charger cable and run maps with screen on and bluetooth streaming music the whole time. Then on the 2 hour drive back home I'll do the opposite- keep screen off, no bluetooth music and no maps but will just keep the charger plugged in and charging. I'll compare temps in each scenario.
[Nexus 5 Accessories] lifeisfun:
Great, looking forward to those results :fingers-crossed:
[Nexus 5 Accessories] Mashr:
Here are the results: the charger is definitely the cause of the heat. Before the trip the battery temp was 23 degrees.

Test 1: Streaming youtube over bluetooth for 1 hour, screen on the entire time with wireless charger plugged in and charging- battery got to 46 degrees!

Test 2: Kept wireless charger plugged in and charging but turned off youtube streaming and screen off (so just let the phone charge) for 1 more hour- battery dropped to 38 degrees after that hour. Still bad.

Test 3: Streamed youtube again for full 2 hours over bluetooth, screen was on, but unplugged the charger so phone was not charging- battery was at 26.5 degrees at the end of 2 hours.

All scenarios the screen was on autobrightness. First 2 hours was during day time and last 2 hours was during night time (so screen probably not as bright). I was highly impressed with the temperature at the end of the 2 hour drive of pure youtube streaming via bluetooth with screen on the entire time, especially compared to my old Galaxy Note1. But very bad in the sense that now I know the charger is causing major heat to the phone. I'm sure 46 degrees isn't too bad for the electronic components of the phone but I'm sure it'll really degrade the life of the battery.

I wonder if it's the magnets we've added to the charger or just the wireless charging technology itself that generates that kind of heat. Again, I've placed the magnets as far to the outer edges of the charger as possible, away from the coil.

Anyone have any insight or suggestions to minimize the heat? I'm thinking to just keep the charger cable unplugged. The Nexus5 seems to be a champ on battery life so I'll only use the charger whenever I'm in dire need of it. Side note- I charged the battery to 100% after the first 2 hour drive, then streamed bluetooth music and had my aplinereplay app on constantly for 4 hours while skiing (uses gps and other phone sensors to log your ski day). Then ran that 2 hour test streaming youtube via bluetooth and screen on without charging, and I was at 27% battery remaining by the end of it all. I'd say that's pretty damn good battery life I'm getting from this phone. I don't wanna screw that up with this charger.
[Nexus 5 Accessories] XorZone:
Well, what kind of charger is it?

I only had heated phone after driving with heater on (my charger is on air vent). Otherwise it was barely warm, less then after 30min of gaming.
[Nexus 5 Accessories] JCreazy:
It looks like the Powerbot chargers on Amazon went up in price.
[Nexus 5 Accessories] Mashr:
I think it's the powerbot chargers we used, but the link doesn't have a name for them.

Sorry for not hyperlinking. Can't hyperlink if less than 10 posts.

I think my vents are adding to some of the heat. The mount is sitting above the vent but still maybe close enough that it's still catching some of the heat blowing. Tried it again with screen off and no vents- it got to only about 35 degrees.

[Nexus 5 Accessories] JohnLocke44:
I'm using 12x2mm N35 to hold the phone, but is not enought to hold it well.

Currently, I'm using 2x 12x2mm N35 magnets + 8x1mm N45 on each corner to hold the phone. With this configuration I can hold the phone without the case, and with the case I need to use a little plastic support with the magnets.

Now, I'm just testing without the wireless charger to ser how it goes.

Does any one had measure the magnetic field when the phone is on the magnets? I got around 750~820uT. Is this a problem?

You can test with an apk using the magnetic field sensor of the phone.
[Nexus 5 Accessories] I[E:
What size magnets did you use? I'm having a hard time finding ones that will hold the phone with a case and fit without modifying the charger.

Hi, i don't use any case.... but i'm using a lot of 3x1.5mm and 6.2mm N52 Grade Magnets...
[Nexus 5 Accessories] xkravenx:
If you are using a case with your Nexus 5. You need to put magnets on the case for the magnets to stick.

If you use the phone naked then the 4 magnets in each corner will work.

Any 1mm in thickness behind the case will work. I have 4 x 6mm-1mm behind my case and it works "well". Without those magnet, there is NO WAY the phone+case would stick to the charging pad. Unless you go crazy with the magnets.

taking apart the t200

hi there,

how did you take the t200 apart? I just received mine and having removed the rubber rings both top and bottom ones, I don't see any screws, etc... Please help.
[Nexus 5 Accessories] modigangster:
hej, i have the t200, too.

It is not a big deal: there is a small plastic "hook" system.

With a (mid to small) screwdriver (the flat one of course) you slowly have to push between the upper part and the (inner) outter part, on the side of your t200.

the positions of the 6 "hooks" are (centerlined):

~1.8cm from the usbplug (each. right and left of the usbplug)

~2cm from the led (again: to each side)

and exactly in the middle between the led and the usbplug

So I start e.g. with the left of the usb, by pushing the driver between the upper and lower deck (be gentle! ~0.66mm are enough and then pull/lever a bit..be gentle again! then go to the one right of the usb.. do the same... wander around.. you got it open.

Hi guys just a question I got it from eBay http://pages.ebay.com/link/?nav=item.view&id=121224255973 and I followed the procedures on the first page of his thread to find the magnetic point on may N5 but when I try to put the N52 magnetic from eBay on the exactly point of the magnect on my N5 this looks like the polarity of the magnet are inverted both sides of the n52... Is any especial magnetic? I know that I can still doing the mods with my N52 from eBay however they not will be on the 4 point magnetic on the Nexus 5. Have you guys noted that?
[Nexus 5 Accessories] jmel:
I really like this specific idea. I've bought 2 of these (black pad with red ring) for my red car, and plan to do the same with the magnets. I will also add an nfc sticker and will try both inside and outside application of the sticker (inside the puck and outside on the face of it, just to see which will work best.

These are readily available on ebay for 8 bucks shipped or so, and that is the 1 amp output model. I hope it works out. I plan to mount this to an arkon plate that slides on to a double pole bracket... similar to this:

http://www.amazon.com/APGN-VSM-Vehicle-Specific-Adapter-Connects/dp/B002ACP2FY

In fact, you could easily cut the ball off of that plate (the slide together on the backside) and use some epoxy or even screws to mount the puck to the plate.

EDIT: got some of these N52 magnets: http://www.ebay.com/itm/50pcs-N52-b...819?pt=LH_DefaultDomain_0&hash=item1e83c85b93

Finished mine

I just finished mine.

It's more or less the same as anyone else here :)

But what i did is that a used trigger and tasker to automate many thing :)

When my phone is connected to my BT AND wireless charging :

- Screen Lock OFF

- Screen On

- Ulysse speedmeter On

- car mod ON

- GPS On

- Wifi Off

- Sound MAX

When my phone is disconnected from the BT ( when i shutdown my car)

- Screen lock : ON

- GPS OFF

- Ulysse OFF

- Car mod OFF

- Wifi ON

- Sound Mute

So basically when i put down my smartphone on the charger, everything is executed without any action from my part.

It's awesome :D
[Nexus 5 Accessories] Larzzzz82:
Try using some sheet metal slices to fill the gap. As I see it, this is an air core transformer, saturating the sheet metal with the magnetic field of the charger should improve the magnetic coupling to the receiver coil.
[Nexus 5 Accessories] premo15:
Good call on the bt trigger, was trying to think of a way to differentiate my car charger from the one in my house. Tried an NFC tag behind the top plate of the charger but it's too far from where the back of where the phone rests to be reliable. I'll have to give the bt thing a go...

then i ran across a universal magnetic car mount in ebay... was like $5 shipped... no charging, but actual magnetic mount

works great for holding the N5.... i would say maybe 70% as secured as my airdock... so i have it on my spare car

but hands down, my airdock is a great investment.. love it

This is my take at the car charger:

By the way, how do your magnets hold? I'm using Neodymium magnets, 10mm in diameter, but they don't seem to hold that well. Even more, they seem not to stick exactly on the metal plates from the phone, but rather on an area around them, like the metal plates were magnets. Even more, they seem to be interconnected, 2 by 2.

Did anyone else notice these things?

PS: I've made sure that I've glued the magnets with the same N-S orientation.

I really wish this Synergy Wireless Charger would have taken off. I discovered it and got excited, only to learn that it failed multiple crowdfunding campaigns last year. :(

Although, back in late April, the company said on Facebook that they were back. Who knows?
[Nexus 5 Accessories] alfavictor:
First off, thanks for the detailed tutorial.

I tried the same with a cheaper wireless charger (this one)

But now, my phone doesn't get charged when it's on the charger.

Does the polarization of the magnets have anything to do with it, i.e. have I placed the magnets facing the wrong side? My charger has a thin magnetic disc stuck to the underside of the induction coil (my guess: to direct the field upwards).

Or is it just that the magnets increased the gap between the coil & the phone? And my cheap charger isn't strong enough to push the field that much farther?

Any help from anyone would be welcome! I'd like to figure out what to do next, before fiddling around with the coil anymore. It looks pretty fragile. The charging coil itself still works perfectly fine. I popped it back out of the case, and hooked it up. It charges my Nexus 5 perfectly.
[Nexus 5 Accessories] daniel_loft:
I don't think it has anything to do with the polarization. Although I made sure that they are facing the same pole towards the phone.

Te metal plate might have something to do with directing the field or protecting the circuit. All I know is that all wireless chargers seem to have it.

Are you sure you are aligning the charger correctly with the coil? The magnets should be forming a square with the side of 37 mm (and a diagonal of 52 mm), or at least that's what I have found.

Other people have noticed that the presence of the magnets heats up the phone a little bit more. And of course that every extra mm counts. I only added about 1 mm extra with mine.

Have a nice day!
[Nexus 5 Accessories] rpr69:
A picture might help, to show us what you've done. I took one of those cheap round Qi chargers apart and put magnets around it, and it works great, so it depends on how you've set it up. The disc under the coil isn't a magnet, at least I don't think it is, mine is not, so I don't think that is an issue.
[Nexus 5 Accessories] alfavictor:
Thanks for the replies, guys!

[MENTION=3541078]daniel_loft[/MENTION], I made sure I followed the 25mm down, 36 mm square measurements posted by OP. So the coils gotta be aligned right.

I also made sure the magnets are all aligned in the same direction. I've also ordered a bunch of thinner magnets off ebay, just in case it's the magnet thickness that's causing the issue. My magnets have increased the height of the charger by 1.5 or 2 mm.

Once again, thank! :)
[Nexus 5 Accessories] alfavictor:
OK, time for an update. My wife has a Nexus 4 and she started nagging me about how I was being selfish about making a magnetic charger that would be no use to her. So, I decided to make a change in the plans so that the charger could be used by both of us, since we share a single car.

I took an old windshield phone mount I had, whose suction cup had broken off. Then I took out the charging circuit and the coil from the qi charger. I then used hot glue to fix them both to the mount. Then I stuck a Bracketron Universal Hold-iT Mini I had left over, and stuck it just below the AC vent. Now, even if the phone does get heated while charging, the AC will cool it! :)

Now the final product can be used to charge my Nexus 5 as well as her Nexus 4. A happy wife makes a happy man! :D

I know it's not pretty to look at, but I guess a couple coats of plastidip can help a bit.
[Nexus 5 Accessories] RokRovan:
Hello everyone!

After gaining some inspiration from this thread, I decided to take a try at crafting a magnetic wireless charger for my N5.

I ordered some magnets, and a qi wireless charger from ebay.

I also ordered a universal car mount, from which I plan to remove the rotating top and screw on the qi charger. The mount hasn't arrived yet. I will update when it does.

First I dismantled the charger and positioned the magnets. I glued them with stringed double-sided tape so they don't move about. I went wild with it just to be sure. :D

As you can see from the gallery, the magnets hold the phone at a decent angle.

Now I just need to wait for the mount to arrive.

PICTURE GALLERY

Cheers!
[Nexus 5 Accessories] Mashr:
Stringed double-sided tape sounds way easier than the hot glue I used! Smart thinking.

How well does the phone stay attached to the mount? Can you shake it about, hang it upside down, etc? Will it survive bumps while driving? I wish I would have used more magnets because mine slowly slides off after hitting a few potholes and speed bumps.
