Oh, sorry, forgot to mention the mount will be for indoor use only. Starting my second college in october and I won't be driving much. Sorry for kinda posting in the wrong thread. :)

However, the magnets hold the phone steady at a 90 degree vertical angle. I plan on using it at around 60 - 90 degrees.
[Nexus 5 Accessories] RokRovan:
As promised, the update:

The mount arrived, to which I screwed the qi charger. I'm quite happy with the outcome, as it is also usable in the car, not just indoor like I planed. The phone sits neatly on the charger and doesn't move about and I think it could hold through road bumps. I might add a magnet or two in the future, just to be sure.

Updated picture gallery: Here.

Cheers!

I noticed the same thing. I bought 1/2" x 1/8" circular magnets from amazon and noticed they don't stick directly to the metal discs on the N5 but rather they tend to stick to one side of the metal disc or the edge of the disc. I wondered why so I tried sticking the magnets to a round metal washer I had lying around and it did the same thing! The metal washer will stick to half the magnet, towards one edge. If you try and push it onto the center of the magnet it repels away to the side again. If you turn the circular magnet on its side it will stick perfectly to the center of the metal disc. The metal discs in the N5 are smaller in diameter than the circular magnets I'm using. I did some digging around and this may be due to so called "edge effects" as described here (scroll down to the second youtube video).

I am wondering if a cube magnet or a smaller diameter but thicker cylinder may work better. Maybe that's why Google used the specific arrangement of cube magnets in their official wireless charger as detailed here.
[Nexus 5 Accessories] bossman137:
Excellent observation! Have you tried sticking 4 magnets on the back of your n5, spacing them out equally, and measuring the actual center to center distance of the magets? I would thing this could actually be a contributing factor to people having so much varying results.
[Nexus 5 Accessories] vesu:
Anyone used N35 magnets? (Circular 1/2*1/8). I wonder if they're enough?

So I have the "powerbot" chargers, cant beat 14$.

and here are the magnets i've chosen for my undertaking

http://www.amazon.com/gp/product/B00CXXJGZC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

They measure 1/16 thick by 1/4 in diameter. I chose these because I correctly believed there to be enough room to stack some magnets inside the qi charger so i wouldn't have any external proof that i've modified the charger.

I tested my post above about the magnets actually attaching to the phones metal circles on the outer edge, and its absolutely true. If you take a magnet and move it around it WILL NOT sit dead center to any of the 4 phone steel circles. THEREFORE, i took my calipers and found that the outer most that the magnets sit on the phone back is actually closer to 40 mm. Which for my plans is PERFECT

So i created a CAD model above of my plans. The image shown is the inside of the top housing for the powermate (ie the part the the phone will sit on). You can see that my plan is to mill/drill .075 deep holes on the outer edges (40mm apart) on the INNER side. That will allow me to stack 3 of my little magnets (creating a 3/16 magnet by 1/4") and in my opinion more than beefy enough.

Also for guys modifying phone cases, you might want to consider cutting a little shim stock. Shim stock is a very thin piece of steel used in machining. ranging from as little as .003 to .050" It works VERY well and you can put it on the inside of the phone again without cutting all the way through.

I am not invalidating anything what you did here. I am an electrical engineer so whenever I see the do it yourself-ers out there, it makes me proud of the level of intelligence people have.

Why didn't you buy the Nexus 5 wireless charger with the magnets built it and attach it to your suction cup mount holder? You would have been done in the time it takes to double side tape the n5 charger to the mount surface. The charger has an unbelievable hold.

I'm going to post my thread link on how I did this in a much simpler way. Again, no disrespect.

Please tell me what you think.

Your project looks good. I didn't consider the nexus 5 charger because it wasn't out yet. I think they announced it the week after I completed my project. [emoji15]

Also there's the price -- the official charger is 50 bucks and you can do the above for less than 20 plus an hour of your time which for me was time well spent. It actually took longer to write it up and post it. [emoji3]
[Nexus 5 Accessories] VOLTAGEROCK:
I got ya now. I did something similar to what you did but with my Nexus 4. I used the rare earth magnets on the lg puck and modified the back of the Nexus 4 with little metal disks that I got from my palm pre touchstone cover. I'm sure if you do a search here on XDA you can see the do it yourself project I did with mine. But I like the way yours looks especially with the plasti dip. Great idea.

[Nexus 5 Accessories] fredoman:
Inspired by the different realisations seen in this thread I try something for myself. My previous solutionwas to fix the official Nexus QI charger on a cheap phone dock and the results were very disappointing : a lot of vibrations and on hot days the phone would swivel down all by itself. Finally the dock arm broke completely.

So I decided to make something simple that fits my needs. Not adjustable, no sophisticated design, KISS.

Materials :

one flat aluminum bar (scrap from a previous project)

Black paint (fast drying)

double-sided bonding tape

Official nexus 5 charger + original cable

~3 hours of time

I am quite happy with the result :

Magnetic Qi Dock for larger phones?

Anyone managed a nice sturdy car dock for a nexus 6 or Note 4?

The bad news is that I suspect the optimal placement for magnets will be different than the nexus 5. Or is the 4 discs 37mm apart some kind of standard? When I look at the back of my note 4 with the back plate removed I see no sign of metal.

The good news is that larger phones allow for more space to place magnets outside the Qi coil. So you could easily put a substantially larger magnet without crowding or creating extra distance between the charging coil and the phone.

Maybe a pair of K&J Magnetics B662-N52 (3/8" x 3/8" x 1/8") at each corner? Or even the B666-N52 (3/8" cube N52). Ideally it would solidly hold the note 4 even if it has a thin case on.

For a sturdier mount I was looking at the QI charging pads that were closer to the phone size. Something like the nokia DT-900 qi charger Ideally moving the magnets further from the coils will result in less heat, less interference with NFC, and more resistance to rotation.

Anyone done this?
[Nexus 5 Accessories] NWKENT:
Have you taken a look at the "Air Dock".. I have the v1.0 and adore it, does well with my Droid Maxx's and Moto G's..there is also a new model being developed, v2.0..the Dev. has a video out, with using specifically the N6, which is exciting for me also because when all the smoke clears, availability, I plan to order a Midnight blue 64gb..see the video and info..

"Praise Jah" YOU people.!
[Nexus 5 Accessories] svetlik:
I contributed to the air dock and was quite pleased that it got funded. However they seem to have made numerous mistakes with it:

* USB port is on top, so the cable makes a 180 degree kink

* suction cup plastic is too thin and stretches or tears on removal

* the suction foam attracts dirt and is rather slippery if not perfectly clean

* magnets are way under powered, it's okay with a perfectly clean phone and suction foam, but add a case and some normal dust and it slips right off.

* the mount isn't reversible, so you can't fix the 180 degree kink in the usb cable.

Just tonight I tested the airdock again. Bare n5 = pretty good, note great, if perfectly placed it only occasionally needs repositioning. N5 with thin case = terrible. Note 4 with no case worse than bare N5, but better than N5 with case, not good enough to drive with though.

There's some interesting posts on magnets, the unique magnet setup of the nexus charger, and how counter intuitively magnets can interact. I can't post URLs yet, but it's on the nexus-5-universal-magnetic-qi-car-mount-t2593798 thread. The basic recommendation is a pair of magnets oppositely aligned under each corner. The maximizes attraction and minimizes impact on charging speed, heat and nfc.

Anyone know if the note 4 has the same 4 metal plates 37mm apart? At least if the airdock is a measure I fear not, it attracts my note 4 dramatically less than my nexus 5.

BTW, I'd love nexus/android dev phones, I've had them all except the nexus s. But the nexus 6 disappointed me. Dim screen, too large, poor battery life, etc. The note 4 fixes all my complaints (bright screen, better battery life, and smaller).. Additionally the note 4 adds replacable battery, same cpu, same ram, and sd slot. I just added a 64 GB Samsung Evo for $25 and the qi charging back for $30. Not sure about the other versions, but the t-mobile version gets you an open bootloader so you can run an AOSP derived android to avoid crapware and get quick updates.

I use this mount without wireless on my bike and I think if I got the N6 or the G3 international version I'd do what that guy did and bend the arms. It's very quick to mount aside from plugging a cable in. It's the closest thing to magnets or an air dock I know of for easy mounting. Maybe those brodit/proclip mounts are faster with the permanent cable built in. I mount my N5 upside down on my bike due to the vol and power buttons so centering the Qi puck would have to be considered. N6 seems to have all those buttons in the center though so centering is probably not an issue. The arm nubs on the side might affect car sight and handling slightly. It's not an issue at all on a bike. Magnets are obviously the ultimate in laziness and rotation quickness but this ram mount is pretty quick too and as sturdy as you can get. You need to use two hands briefly mounting and dismounting. I actually got used to using the N5 in portrait for the car mostly due to the polarization in landscape. Hopefully I can make it look nicer than this guy combining it with a proclip short type base withoiut that long arm.

I didn't get N6 due to lack of metal mounting points and AMOLED thats burn in prone. Phones with built in Qi are rare enough and I don't expect to see another like N5 with Qi and mounts even though I wish they all had them like that.

I think the air dock maker might be updating it to with with N6 so it can stick well just with the weird foam it uses. I never tried it myself. I broke my N5 last week and just got another N5 because its the perfect phone and nothing else has the easy mounting. The N9 has like 8 spots that magnets can stick to but no Qi unfortunately.

EXELIUM UP magnetic mount

Hi Guys,

If you're already interested about a magnetic & Qi car charger, a french company has designed this and their products are very interesting! :);)

The name of this company is EXELIUM and you can visit the exeliumstore.
[Nexus 5 Accessories] OneDon:
I might as well try this method, since I got two of those wireless chargers around! Thanks
[Nexus 5 Accessories] undercover:
That's my plan. Waiting for charger then I will disassemble it and see what max depth magnets I can get.
[Nexus 5 Accessories] Camel04:
Has anyone tried this type of dock with a case? I gathered the parts I need to make a similar dock, and just playing with the magnets so far, they don't seem work at all with the Supcase beetle case I've been using. Is there a case out there that's thin enough to work with magnetic docking?
[Nexus 5 Accessories] pedxing:
I think that's a good idea. I didn't do it because the coil was held in with some sort of adhesive and I didn't want to screw it up getting it out. But if you're careful you should be able to get it out... Maybe a heat gun would help.
[Nexus 5 Accessories] green_comet:
You guys could try the Metrans MWT03, it had the same specs as the LG charger along with the 1000mA output. It's very well made, charges fine and is pretty cheap.

I pulled mine apart earlier today, it's easy to get apart and the circuit board is easily removed with just 4 screws. Should be very simple to mod.
[Nexus 5 Accessories] Dani897:
they should all have about the same specs. it's all part of the qi standard. i did some reading and qi specifies 5w charging so all but the knock off chinese ones will be 1000ma since 1amp at 5v is 5w. there is a comunication protocol that goes with Qi and the phone controls the transmitter requesting more or less current. so one charger shouldn't be much better than another. there is also a standard for magnetinc docking, just seems the after market hasn't caught up.. you can buy the coils and microcontrollers from mouser but the cost of the parts is more than the whole.
[Nexus 5 Accessories] JKingDev:
Great guide! Just what I was looking for. So how is the strength of the half inch magnets? Are they too strong? Does it pull too hard at the suction cup when you try to remove your phone?

I am shopping to do this DIY now :). Heres my list so far:

Charger (The same one you used)

Magnets (Looks like what you used; 1/2"x1/16", 3.2 lbs pulling force each)

Plastidip (White so it doesnt start marking the back of my N5)

Mount (Hopefully I can easily remove the existing magnet)

1/2" Forstner bit (or 3/8" forstner bit)

Alternatively I could go with some 3/8 inch magnets (2.3 lbs pulling force each) if the 1/2 inch are too strong. I want it firm enough to survive my spirited driving but not so firm that it is difficult to remove with one hand without pulling the suction cup off. Please give comments on your magnet strength.
[Nexus 5 Accessories] daLareid:

It's never been an issue with my Nexus 4, Galaxy S4 (I added some ferromagnetic bits inside the back cover), or Nexus 5. I don't think I even noticed any compass issues, and I'm using a setup with ~16 neodymium magnets arranged in a pad.
[Nexus 5 Accessories] Mr.Blub:
Do you know if these magnets are strong enought to hold my Nexus 5 with a case (Reath Ringke Slim)? www . amazon . de/10x-Neodym-Magnet-Whiteboard-Magnete-Haftmagnete-Pinnwandmagnete/dp/B005C8SXRW/ref=sr_1_1?ie=UTF8&qid=1384885170&sr=8-1&keywords=neodymium+magnets (Sorry for German side ;) )

This is only a temporary solution but I've been using it for a week and it work very well but I prefer not to have magnet on my case.
[Nexus 5 Accessories] JKingDev:

[Nexus 5 Accessories] cntrdctn:

omg.. someone should make this and sell... so good
[Nexus 5 Accessories] pedxing:
Actually some people have said the magnetic compass doesn't work but I haven't had any problems... Several apps that claim to give a compass heading ( it may use GPS I don't know for sure) work for me with this setup.
[Nexus 5 Accessories] loki980:
Does this solution allow you to rotate into landscape mode without issues, or does the charging stop?
[Nexus 5 Accessories] pedxing:
The half inches seem perfect to me. Mag strength is a function of inverse distance (cubed?) so it fades REALLY quick. The mm or so of the back of the phone causes the pull strength to drop to a reasonable level. maybe a pound or two? Metal to magnet is almost unusable with these so that small amount of plastic is perfect. No problems with road vibration or bumps.
[Nexus 5 Accessories] Johmama:
Thanks, OP. With this info I might actually make my own Qi charger mod. It's nice to know that it's so easy. I never would have thought about the separate magnets or the plastidip.
[Nexus 5 Accessories] JKingDev:
Awesome thanks for the tip. Orded my parts! All shipped by amazon with free 2-day shipping from prime. Cant wait to assemble it!
[Nexus 5 Accessories] pedxing:
Thanks for all the great comments, I really appreciate it!

As a side note, props to the wcp 300 charger. I've tested for a few days now and with screen on all the time, nav running (waze) and music streaming over Bluetooth it (Google music all access service) it will still consistently charge 8% per 45 minutes.
[Nexus 5 Accessories] bleuxeon:
First of all : thanks for this very informative post :good:

It would be very interesting to see your battery temp graph while off charger and while on.

I m thinking to do something like you but with an additional small fan, but this would be pointless if temps are similare to standard car usb charging.
[Nexus 5 Accessories] oneonezerosix:
Great work.

I was looking to do something similar with this:

http://www.amazon.com/Cradle-less-Q...Windshield/dp/B008IOQ3K6/ref=cm_cd_ql_qh_dp_t

and some wireless charger.

I read in a review that the dock works with the Nexus 5 out of the box, so the DIY mod seems pretty straightforward.

However, I was wondering if you have seen any issues with the NFC functions, battery and or performance after continuous magnet exposure?

Thank you.
[Nexus 5 Accessories] JKingDev:
I am also using that dock that you linked (see my shopping list above). The fact that it already works with the N5 is irrelevant though since the existing magnet from the dock should be removed. It will be way too far away to be effective with the charger in front of it. All you need is something that the qi charger will easily mount to. The iMagnet looks like a good candidate and I like the low profile and range of motion. I plan to put it on the dash. I will be receiving it in the mail tomorrow (gotta love amazon prime) so I will take some pictures and report back how easy it is to mod that mount.
[Nexus 5 Accessories] pedxing:
No issues do far. NFC seems OK for normal usage... I haven't tried using an NFC tag on the charger itself. I think some other people have done that with no problem.
[Nexus 5 Accessories] pedxing:
As requested I took a log of the usage and temp today on the way home.

The drive was from 4:35 to 5:10. I should have changed the record frequency to 5 minutes or less but I forgot. :confused:

Anyway, it seemed to top out at 50C which is pretty hot for normal non game playing usage but not crazy hot. It got to this temp towards the latter part of the drive.
[Nexus 5 Accessories] JKingDev:
Heres an option. Already has magnets built in:

http://www.androidcentral.com/nexus-wireless-charger-2013

Not sure if they are strong enough for car use though. At the least it would be a good idea to plastidip the surface to get the grippy texture. I'd still rather do it this way though. More fun :).
[Nexus 5 Accessories] bleuxeon:
50°C :eek:

It is a WBK : Wireless Battery Killer :cyclops:

It realy needs some kind cooling.
[Nexus 5 Accessories] JKingDev:
Was this under the condition of running gps + streaming music over bluetooth + charging? If so, I am not surprised. If it was just sitting there charging I would be a little concerned.
[Nexus 5 Accessories] Powerpuffman:
For those wanting to do this DYI with the iMagnet car dock, I went ahead and disassembled mine for you.

I'm planning on attaching the official Nexus 5 wireless charger to the iMagnet, shouldn't be too complicated from the looks of it. I only worry that the magnets in the official charger aren't strong enough to hold the Nexus 5 in place while driving. They do seem a little weak from the videos I've watched. The magnets in the iMagnet mount on the other hand are really strong!

Now I just need to find somewhere I can buy the charger in Europe...
[Nexus 5 Accessories] pedxing:
Yes full heavy use... Actually the last few minutes included a voice call in addition to everything else. Nav was still going but I guess the music paused.

Also keep in mind that 50c or 122f is not a huge amount for electronics or a battery (which is admittedly lower than the CPU). Its still upwards of 135f...many are rated for higher. Obviously life could be affected... But probably not for a while. Extreme heat causes the phone to first throttle and then turn off to protect itself.

That said I did find a little bracket on amazon that's compatible with my mount with the long neck that I was using before. Its only $6 so I guess I'll go ahead and do it out of paranoia sake.
[Nexus 5 Accessories] JKingDev:
Ah, beat me to it :). My iMagnet and LG charger gets here today. It looks perfect for the job from those pics.
[Nexus 5 Accessories] bleuxeon:
50°C is for sure safe for electronics but for battery it would drastically reduce its life span but also its charge quality.

I m thinking to do something maybe with a small TEC Peltier plate in order to draw the heat from the charger or even better the phone itself directly outside the mount.

This would ofcourse suck more power for the same charging, but keeping everything cooled, phone and charger, would definitely be a plus.
[Nexus 5 Accessories] JKingDev:
Interesting idea. One thing to keep in mind is if you put the peltier between the phone and charger, you are cooling the phone but heating the charger up. Of course the battery is more important to keep cool than the charger but now you are dumping lots of heat onto the charger's electronics.
[Nexus 5 Accessories] bleuxeon:
I am thinking to an other way to inteface the TEC, and the simplest way I can imagine for now is to cool both charger and phone and so TEC would be placed at charger back.

Obviously, with this config, cooling would be very poor but on this other hand it should be much easier to do.

For now I have nill experience with wireless charging, so I need first to buy one, then I would buy some TEC module and test...

let's my bank account to raize a litle ;)
