Converting your Nokia wireless charger into a car charger

If you've been wondering if the Nokia wireless charging pad would make for a good car charger, take a gander at the above video. MakeIt Diy is offering a "do it yourself" guide to converting a charging pad into a car charger/cradle.

The charging pad is held into place with a Garmin Nuvi vent mount and hard wired into the car's fuse box using a "add-a-fuse" attachment that can be picked up at most automotive stores.  You'll need to glue a mounting plate to the back of the charging pad to mount it to he vent mount.

To better hold the Windows Phone in place, neodymium magnets are taped to the charging pad and inside the skin case on the Nokia Lumia 920. It's not a bad solution to hold you over until Nokia releases a wireless charging cradle for the car.

Awesome, but I want to see this with the charging stand.

How many 920s does this guy own? And both in yellow???

Vheissu says:

Most people that can afford a Lamborghini can afford a couple smartphones

DaSchnee says:

I highly doubt that this is a Lamborghini. He just bought himself some Lambo-style door hinges.

andrewq911 says:

Yea that's not a lambo lol.

j_the_geek says:

Must like yellow, the car looks yellow too.

Don't know how many, but I'll appreciate he offers me one... :P

bono5112 says:

There's no way that phone stays attached on a rough road, maybe I'm wrong but I just don't see it

hopmedic says:

Those rare earth magnets are pretty strong. It wouldn't surprise me.

LogioTek says:

Then you've never tried to pull apart 2 Neodymium magnets before

Yeah he has more then enough magnets to keep it on there!

Iskassasya says:

The magnets won't affect the phone? I put my Lumia 820 in phone with a magnet thing came out all spasticated.

Cellus13 says:

Best part of the video: A Lumia recording a Lumia!

ggonzalez777 says:

Inception Lumia!!!

Looked like he had scissor doors

cdbstl76 says:

Yeah, I wanted to see the car too

erzhik says:

I would never use magnets on my phone. Just too risky.

Magnets wouldn't hurt a cell phone! Maybe your thinking of volatile memory storage getting wiped from days of old?

Beezie84 says:

I was thinking the same thing.. Magnets can't be good for the phone..

LawnPaul says:

Wouldn't magnets on the phone mess it up? Like a computer. I have friends that fried computes from things like speakers sitting on the tower.

Fiann says:

You do realize that there are fairly large and VERY powerful magnets inside the hard drive of your PC? The only way magnets would be an issue is if they are moving so as to generate an electric current.

takisrock says:

This is just stupid!!!!!!
He put magnets???? how the magnets cannot affect the device?
and why he didn't buy a normal holder and a lighter charger?

bdlou says:

Maybe it's not this hack that is stupid...

Alex Kj says:

You guys are just LULz... There's absolutely no negative effect on your smartphone by magnetic field from such magnets, they are perfectly safe. Your phone doesn't store your information on moving magnetic tape or disks ;-)

Have you ever taken a magnet to a display screen before? Phone, TV, Monitor, or otherwise? 

Ordeith says:

LCD? It wouldn't do anything.
CRT? those use magnetic fields to focus the beam on the tube, disrupting that field will disrupt focus.

Speakers and mix might be affected, small magnets are usually used to produce vibration there.

DaSchnee says:

The e-compass gets messed up and sat-nav apps like navigon take advantage of it.

PeterFnet says:

Cars output around 13.7 volts when the engine is running. My wireless charger is at work, so I'm not aware if it lists supported voltages: example 10-15 Volts. Without knowing the internal circuitry, I'd be concerned about damaging the charger and/or phone.
Edit: Perhaps a voltage regulator would help.

deloa84 says:

That's why the instructions call for an added fuse to protect both the device and the phone. Therefore it blows a 5cent fuse and not your device/phone. I am sure it will suffice since most in home outlets are ac currents and output 120volts. Car electricity is very static and it is dc instead of ac. A fuse can go a long ways.. It just has to be the right rating which is 15 from my understanding...

PeterFnet says:

Vehicle fuses are rated for current with an assumed voltage range. A car's alternator will always push well over 12V when the engine is on. AC varies in houses which is why those AC to DC power blocks regulate the outgoing DC voltage. Vehicle power will spike and vary, especially while starting the engine.
The wireless charger is getting raw voltage from the car. Fuses won't help here.
Pardon my word vomit. Typing on mobile app and don't feel like reorganizing my thoughts.

deloa84 says:

You're right about the alternator pushing over 12v but all they do is replenish the battery while the vehicle is running, not sure if that changed for the newer cars more than likely it did... I do not see why a fuse wouldn't help. Fuses in cars are there to protect pricey electronic parts. Don't want to sound mean (or noobish lol) or anything but can you clarify why a fuse wouldn't work?

PeterFnet says:

Yeah, the vehicle uses the higher voltage to charge the battery. But that voltage is seen by all vehicle electronics. These vehicle electronics are designed to handle that greater voltage.
It is likely that the wireless charger will not handle more than 12 volts over time. The fuse will allow the expected 13.7 volts.

BoBallistic says:

I wouldn't do this until Nokia released an official wireless car charger.. Seems sketchy

NIST says:

Hopefully it doesn't degauss the phone memory.

cowboy620 says:

I could easily make it into a wireless car charger. most newer vars like my "2005 ford escape hybrid" has a 110 v outlet so power would not be an issue. I'm just looking for a good car mount for my red 920 to attach the wireless charging pad too. Iwill upload a vid when I do it.

Sulslim says:

Would be nice if charger would be with NFC - to play music in car !!!!

FishOfPrey says:

The hard iron (permanent magnet) distortion to the magnetic field detected by the magnetometer should be handled when you calibrate the compass. I'd guess this will need to calibrated every time you move the phone relative to the dock. I.e. The compass will be off when you put the phone in the dock or remove it.

MacDaMachine says:

Pretty slick...

freel123 says:

(I'm the guy who made the video).
The magnets don't mess with the mapping apps at all. I've been using Nokia drive and maps without issues. I don't really use the compass for anything so that's not really a concern. The camera seems to work fine too. I was concerned about the effects the magnetic field might have on the phone's hardware, but flash memory is unaffected by magnetic fields and besides, wireless charging subjects the phone to a varying magnetic field anyway, and the phone seems to be built to handle that. So far, I've been using the case with magnets for about a week with no problems.
For people who are still concerned about using magnets, you can try a different method for attaching the phone to the charger. Maybe velcro might do the trick. For me personally, magnets work just fine.

nizzon says:

What kind of car is it? Pics! :)

strikexx says:

Looks like the dashboard of a Hyundai Coupé 2.7i with a modded door to me...

Compare for yourself:

sorry for CAPs, but ...  HOW COULD YOU RECORD IN 240p WITH 920 !!!!!????
