Introduction: Keep Your Tech Handy With Sugru + Magnets + the Queen!

Picture of Keep Your Tech Handy With Sugru + Magnets + the Queen!

Whether you're off on a long road trip or just popping down to the shops, it's always good to have your tech close at hand. This project shows you how to keep your phone and GPS device just where you need them, using Sugru + magnets + err the Queen! :)

OK let's explain. Recently we realised that certain coins here in UK are magnetic (1p's, 2p's, 5p's and 10p's). They are not as strong as a second magnet, but are perfect for some applications. In fact, all kinds of metal objects could be used...

This means you can make your Sugru + magnets kit go twice as far, just by substituting a magnet for the Queen's head! (For those of you outside the UK, a washer or something else magnetic can work too)

For the phone mount we used

- x1 minipack of Sugru - buy some Sugru

- x1 neodymium disc magnet - we used the magnets in the Sugru + magnets kit

- x1 UK copper coin (washers will work too)

For the GPS mount we used

- x2 minipacks of Sugru

- x2 neodymium disc magnets

- x2 UK copper coins

Check out our other 'ibles using our Sugru + magnets kit - including how to make awesome snap-on bike lights and this smart way to declutter your space.

Step 1: Attach a Coin to the Back of Your Phone

Top Tip: One minipack of sugru is enough to attach two coins or two magnets.

Cut open a mini pack of sugru and divide it into two equal parts.

Squidge one piece onto the back of the coin and press it into a pyramid shape.

Then carefully but firmly press the magnet onto your phone, so that sugru squeezes out around the edge of the magnet. (enjoy that moment, it's soooo satisfying!)

Top Tip: Make sure the surface you are applying the sugru to is clean.

Step 2: Attach a Magnet on Your Dashboard

Using the method from Step 1, build a sugru pyramid on the back of the magnet, and attach it to your car's dashboard.

We also added a little blob of sugru, to keep the phone stable.

Leave the sugru for 24 hours to fully cure.

Then enjoy your new snap-on phone mount!

Step 3: Attaching a GPS Device

Using the method from Step 1, attach two coins to the bottom of your GPS device.

Use the coins to measure and mark out where you want your GPS to sit on your dashboard.

Top Tip: make sure the coins on your GPS and the magnets on the dashboard match up to ensure a nice snap!

Attach two magnets on your dashboard.

Leave the sugru to fully cure for 24 hours before using.

Enjoy your new snap-on GPS mount.

Step 4: Keep Your Cables Tidy

We have also attached a coin to our GPS cable, to keep things nice and tidy.

If you've found any other clever little uses for sugru + magnets in the car or anywhere else, we'd love to hear them.

Thanks for being part of the sugru community.

be nice. kind words can go a long way, especially when you disagree with a statement.

ElizabethGreene (author)2016-01-04

The attached image may be helpful for US viewers. As of 2016, our coins are non-magnetic so you'll need to use a metal washer or somesuch instead.

tobywinks (author)2015-01-31

I've thought of this before but have stopped short of doing it because I was afraid the magnet would damage electronics.
I remember back in the day setting a magnet on a floppy disk would erase it.

rundmcarlson (author)tobywinks2016-01-03

Floppy disks actually work by storing magnetic fields in the disk, just like spinning hard drives do. Phones use solid state memory which is much more resistant to magnetic fields. I would not recommend this though, because some phones like the note series will have features ruined by magnets. Magnets will break the pen digitizer functionality.

Peterhl (author)rundmcarlson2016-01-03

Actually the floppy was inert the magnets in the drive motor were shielded. a magnet accidentally placed on or near a floppy would scramble bit not usually erase the whole thing. Much more annoying in my book. BTW has anyone seen a floppy recently?

venustus (author)tobywinks2015-02-03

In a phone you have lots of magnets allready ;) in speakers microphones and other electronic components. I don't think the magnetic field will harm your phone because all the sensitive components are shielded.
The magnet vs floppy disk story is funny. To erase a floppy disc with a magnet will take like 20-30 years or so. You have a motor in a floppy that drives the disc around and the motor is actually having magnets inside =D

lfoss (author)venustus2015-02-03

20-30 years? I could erase a floppy disk with a magnet in 2-3 seconds. It really depends on the strength of the magnet. Just sayin'..

NeightR (author)2016-01-03

I'm always looking for new uses for Sugru. Thanks!

knowlj (author)2015-02-20

I wonder how easy it will be to remove the sugru when the time comes.

joegatling (author)knowlj2015-02-25

Agreed. Do you happen to have a photo of the place on the dashboard after the blob of sugru has been removed?

scottfree1 (author)2015-02-03

Sugru $70 oz.

InstaMorph - Moldable Plastic $1.40 oz.

dsantil71 (author)scottfree12015-02-21

At an 8 pack of Sugru costs $21.25. 8 pack of 5 grams each = 40 grams The link is below. Also at a pack of 10 neodymium magnets 1/2 in x 1/4 in costs $5.86. The link is also below They used for the phone mount alone 1 Sugru mini pack 5grams= $2.65 1 neodymium magnet = $0.59 1 washer (had on hand) $0.00 (substitution for UK coin) Total $3.24 For GPS mount 2 mini packs 10grams = $5.30 2 magnets = $1.18 2 washers (had on hand) $0.00 (substitution for UK coin). Total $6.48 For both projects 3 mini packs = $2.65 per pack Total $7.95 3 magnets = $0.59 per magnet Total $1.77 Total $9.72 By my calculations these are some of the cheapest mounts a person could make. If they have more than one vehicle they could make additional mounts for that vehicle, for their bike, for friends if they purchased an 8 pack of Sugru & 10 pack magnets or any number of other projects too. One of the things about Sugru is a little goes long way. Plan to do a lot of projects when you open one pack so make good use of it! Sugru 8 pack $21.25 Neodymium Magnets 10 pack $5.86 =$27.11 $7.89 needed to = $35 to get free shipping. Wouldn't be hard to find $7.89 to spend. Free shipping with purchase of $35 & over Link is below

scottfree1 (author)dsantil712015-02-22

Well they need to fix their product description, it seems like you are correct on the weight but the only way to know that is to zoom in on the picture and read the label, the actual product listing states you will receive about 8.5 grams, if they don't want people thinking the stuff is $68 an ounce then they should stop saying it..

And the cheapskate prize goes to...just kiding bro, that fairly give the same result, much cheaper. You know... outside U.S or Europe is very hard to find Sugru products to buy, but this one you showed, I got on my shelf. ;D --- by the way, to the author, great project... I'm ready to stick stuff on my gads

scottfree1 (author)raguiar12015-02-03

I'd never heard of the stuff before now, I'm not sure if pointing it out is allowed, this seems to be a thinly veiled ad for sugru, well more an outright advert for sugru, but amz sells 1/3 oz for $21 vs. $17 for 12 oz. of InstaMorph, and the only way to deny that is not to charge a 50x markup or 5000% if my calculator skiilz are correct..

dsantil71 (author)scottfree12015-02-21

Then by ur standards every instructable that uses sugru must be an ad for sugru, please. There are a ton of instructables using sugru. It's just a very versatile product for the DIYourselfer that's all. Some people may use more than what's needed for a given application but that's where everyone can try something different for themselves. Use less or use more it's up to you.

scottfree1 (author)dsantil712015-02-21

instructable brought to you by "The team behind Sugru, the mouldable glue that makes fixing and making easy and fun. Do-ers of the world it's time to get excited."

No posts by SUGRU about SUGRU suggesting you use a bunch of SUGRU are not by MY definition an advertisement, maybe you should talk to Webster, get them to change their definition then I'll consider changing my definition of what this is..


noun advertisement \ˌad-vər-ˈtīz-mənt; əd-ˈvər-təz-mənt, -tə-smənt\

something (such as a short film or a written notice) that is shown or presented to the public to help sell a product or to make an announcement

a person or thing that shows how good or effective something is

the act or process of advertising

mfluharty2 (author)raguiar12015-02-03

There is an instructable on how to make your own suguru substance by using calk and corn starch.

millmore (author)raguiar12015-02-03

InstaMorph becomes soft at 140F - easily achievable in a car on a hot day. Sugru goes up to almost 400F. I know which one I would use in a car!

scottfree1 (author)millmore2015-02-03

True, but at $70 an oz. to protect say an iphone 6 plus 64gb which in comparison costs $66 an oz. I think I'll park in the shade..

Years ago I made a magnetic holder for my HP Ipaq PDA. It worked fine with that but erased the hard drive of my Swiss travelmates ipod. She was not happy! Then couple years ago I bought a case for my Samsung Note pad. I wondered why compass and some other apps stopped working? Sure enough there was a strong magnet on the case. I operated with sharp knife and removed the magnet. After calibrating the compass everything worked fine again.

taylor_s2 (author)2015-02-06

Okay, I can see this Sugru mount system for a GPS. But for a phone? That big bump will catch on my jeans pocket or jacket pocket every single time.

dewragdave (author)2015-02-03

First of all Sugru and InstaMorph are completely different substances. Sugru is a mouldable glue that bonds to various items and turns to rubber. Once cured it will withstand -58f to +356f temp range. InstaMorph is a mouldable hard plastic that only bonds to some items if it is overheated. If heated again to 140f-150f it will sag but can be reused over and over. Also all coins in the USA are non magnetic so you would have to use another magnet or a metal washer or slug etc...None the less both are useful products and this is a "good product use" instructable. Sugru can be bought at Lowes and Radio Shack. InstaMorph on Amazon and eBay.

scottfree1 (author)dewragdave2015-02-03

No argument, I'm not an expert just got the id email and this caught my eye. But looking at this with corner bumpers, 6 mount points, "blob" to stabilize, coin attached to cord, this what a $40? $50? Maybe more, this for "solution" to a problem you did't know you had, or is "how do I glue coins to my dashboard?" one of life's great unanswered questions??

dewragdave (author)scottfree12015-02-03

You got that right, there are much cheaper solutions, especially for a GPS which comes with it's own car mounting hardware for free. LOL

Spokehedz (author)scottfree12015-02-03

I got a three, 3g packs for $10 at a local store of mine. With your kind of math, you should work for the MPAA...

scottfree1 (author)Spokehedz2015-02-03

Mkkay here's my "trick math", I take exact same numbers as the they use in their listings, and here's the "trick" I multiply those numbers so I can get the price per ounce, pretty tricky. But shh.. I don't want people figuring out how I "tricked" them..

Amazon Weight 0.3 ounces x 3.3 = 1oz

Price:$21.07 x 3.3 = $69.53 oz.

Microcenter Weight 0.17 oz. x 5.8 = 1 oz.

Price $11.99 x 5.8 = $70.52 oz.

Spokehedz (author)scottfree12015-02-03

(I do not work for Sugru. I want to make that clear from the start.)

Ah, so it is more along the lines of Straw Man math. I see now. Thanks for clearing that up. Would have been good to point that out in the beginning.

Because I thought, and I can only guess a few others did too, that you were saying that the 1 minipack (3g = 11.99 / 3 = ~3.99 per gram) as outlined in the Instructable was $70. Or that you needed $70 worth to actually do this project. Both of which are wrong, by the way. But you were using the weight of a product that was for something entirely different, and would not actually work for this project, and simply making a comparison of the weights between the two. My mistake!

And yes, I can say that you absolutely can use 1.5g on each part of the magnet/metal and it will work FANTASTICALLY. They really use way too much in these instructables. You don't need it to smoosh out and surround the sides like they have there. A little between the surfaces to be mated, and maybe a tiny bit of it squishing out around the sides is PLENTY.

And as for the price, if a product works and works well--then it is worth the price. I do not know of another adhesive/putty that has all the qualities of Sugru for the price they charge. Yes, there are similar products, even cheaper ones, but I have tried a few of them and they always seem to fail much more often than Sugru does.

lumpkin75 (author)2015-02-03

I'm concerned about damaging my dash or console. I'll probably sell the car later and don't want to reduce its value. I would think in order to trust sugru or a substitute, that it would have to be difficult to remove.

scottfree1 (author)lumpkin752015-02-03

"I do not work for Sugru" and I sure as he|| don't, but I suspect we might be the only 2 in the mix who don't. As far as the product if they treated it like most people would treat an expensive specialty adhesive, and didn't slather it everywhere like it was elmers glue then I would be less inclined to complain about this little piece of theater sugur has put on here. But when you start gluing coins to wires with stuff sold @ xxx $$ per gram then my bs detector starts laughing at you..

scottfree1 (author)scottfree12015-02-03

Same idea for $0.30c worth of high strength "acrylic" hot glue (jewelers glue for mounting gems)

jmengel (author)2015-02-03

Instamorph is a polycapralactone polymer like shapelock which melts at a low temperature and is hand formable into any shape before it cools into a hard polymer. It will not stick to your coin, your magnet, your dash, or your phone. So while much cheaper than Sugru it is in no way comparable.

scottfree1 (author)jmengel2015-02-03

I'll have to take your word on that, but when you shop for "sugru" on amazon InstaMorph is one of the alternate products offered (see the link I posted it was sugru I searched for) As far as being "in no way comparable" well here's a pretty comprehensive run down of the products available in this area, and I guess you need to request a redaction of the section where he specifically compares sugru and InstaMorph..

useraaaaa (author)2015-02-03

why not to use Two Magnets?

why One Magnet and One Coin? Do you really hate Queen Elisabet 2.0 ?

scottfree1 (author)useraaaaa2015-02-03

I've found with to good magnets (I love neodymium's for mounts they pull like a black hole) but use anything short of 2 part epoxy or acrylic hot glue and they will suck right out of whatever you're using to attach them including "sugru"..

LittleMonkeyMojo (author)2015-02-03

Will this affect the usability of the Compass App on my phone?

useraaaaa (author)2015-02-03

btw 1pound coin does not have weight of 1pound (cheaters!!)

mastermind26 (author)2015-02-03

Would the stuff be permanent?
If so, having a phone case for your phone should be one of the steps (or clarification for step 1).

If not, how do you clean off the suguru from your phone without damaging it?

Arghus (author)2015-02-03

the world thanks you

Codswallop (author)2015-02-03

A very clever project that I absolutely must try. However, I am constitutionally incapable of refraining from mentioning that if a coin will adhere to a magnet, it is not copper. Only ferrous metals adhere to magnets. Thus, the "copper" coin undoubtedly contains a good measure of some steel alloy, thinly coated or mixed with copper.

3366carlos (author)2015-01-31

nice. what would happen if the queen finds out you are using coins for that? Your watchband looks cool, what is it?

smeyer7 (author)2015-01-30

love it!

smeyer7 (author)smeyer72015-01-30

eventhough i would'nt suguru my phone... maybe if i'll get an extra case for it xD

craftclarity (author)2014-05-06

That Sugru stuff is pretty dang handy, yeah?

hunter999 (author)2014-04-27

Very nice idea!
