Magnetic Car Mount for IPhone, Droid and Other Smartphones





Introduction: Magnetic Car Mount for IPhone, Droid and Other Smartphones

Here's an elegant solution to to all of those out their who fiddle with their phones while they drive. Whether it be following Waze, looking up a restaurant on Google Maps, or dare I say texting, using you phone while you drive is dangerous - and I wanted a solution.

"Design is not just what it looks like and feels like. Design is how it works." - Steve Jobs

My requirements:
- no clips
- no stickers
- on and off in 2 seconds
- sturdy
- car/phone looks good when not in use
- 100% built by me

So I got to work and this is what I came up with. Enjoy my first Instructable!

Step 1: Ingredients

I don't have exact measurements for the parts that I used, I'm sorry! Good news is, I got everything at Home Depot in one isle. Even the magnets.

"Grocery List"
- 1 Corner Bracket
- 2 bolt (with nuts) that fit through the corner bracket
- 1 magnet with hole that allows the bolt to pass through
- 1 washer that does NOT let the head of the bolt pass through
- 1 washer that DOES let the head of the bolt pass through
- 1 tube of quick setting epoxy (I got 3200 psi)
- 1 smartphone of your choice
- 1 cheap plastic case for your phone

- look at the pic lazy

Step 2: The Case

The project consists of two parts
1) the case
2) the dongle

Since the case requires the use of epoxy, we'll get it out of the way so it can dry while we're making the dongle. 

Mini Steps:
1) center and outline the bigger washer (the one that the bolt can pass through) on the case
2) scratch up the surface so that the epoxy bonds better (scratching the surface increases the surface area the epoxy has to bond with)
3) mix and carefully spread the epoxy on the case
4) stick on the washer and let it dry!

Step 3: The Dongle

The project consists of two parts
1) the case
2) the dongle

Mini Steps:
1) stick the magnet to the bracket
2) stick on the smaller washer
3) insert the bolt
4) bolt on the nut to the back and tighten
5) attach the other nut and bolt to the other side for safe keeping till mounting

Step 4: Replicate, Mount & Enjoy!

Make a couple more for everyone in your family - they all work! After all, they do have to deal with a stupid metal dongle sticking out of the dash lol.

I didn't include the mounting process because we all have different cars! For those interested: I peeled off a couple parts from the console, just drilled a hole and bolted the thing on. I had to shave away some plastic on the inside that was getting in the way, but it all turned out great.

    Won't the magnet damage your phone?

    no phone circuitry is very solid compared to a computer or other things that get damaged by magnets. so far magnets havent hurt my phone and i have high power neodymium magnets

    Indeed. I work in labs with electromagnets many thousands of times stronger then these and my phone hasn't had any issues when I forget about it in my pocket. For reference, these magnets will draw keys from 10 feet away.

    Seems like you could use a single solid rare earth magnet button epoxied to the dash or mirror and epoxy a washer to the case like you did that just slides over the magnetic button, that way you'd have both magnetic and physical forces holding the phone, but still be able to twist or remove easily. Thanks for the ideas!

    alot of good it does to post a video, then make it private so no one can see it.

    I would think several smaller magnets rather than one big would be more secure and less likely to cause damage to phone. Would prevent ability to turn the phone, but I'm wiling to sacrifice that for the knowledge that I'm not damaging my phone....

    Nice. I bought a Breffo Spiderpodium for about $20 on Amazon (I presume they are still available), and have it attached into the vents on my 3 series. No damage to car. Adjustable to anyone else's phone and/or if I change cases. Regular length cable will reach from the USB aux port in the arm rest up to mount (although then I have the 'unsightly cable' draped across my car.

    Hi, great instructable!! Only one cuestion, the magnet isn´t dangerous for the display or memory card? Saludos from Chihuahua, Mexico.

    Some phones have a Magnetometer (compass) chip that will be useless while in the presence of any magnetic field. As long as the phone contained NO ferrous material (metal attracted to a magnet) the compass interference would most likely go away as soon as the phone was pulled away from the magnet. If however, there was ferrous metal, it could leave the compass pretty much permanently affected.

    I wouldn't expect it to mess with the GPS very much but it will leave the Magnetometer (Compass) useless.
