Instructables

Applying for a job with the secret services or just protective of your iPhone?

Either way this is an instructable for you.This holder can not only withstand  bullets and pellets from  low caliber guns and air rifles but is stab proof, protects your smart phone from falls, from hits by a  hammer and even will survive someone jumping on it , I have tried and tested these ( yes, I have even shot at it) as you can see from the second picture .
In fact you can make a holder for just about any phone (you could even make one for an ipad) its just that the dimensions which I will give in this instructable will be for an iPhone 4/4s. If you would like me to post an instructable to bulletproof  a different device please leave a comment.

In this instructable I will teach you how to build a bullet proof iPhone case from materials which are more readily available and cheaper than pre-prepared bulletproof materials such as Kevlar.
This case will cost you approximately $25 / £15 compared with about $90 / £60 for a pre-made bullet proof plate.



Materials:
-55 x 20 cm sheet of mild steel , 3 mm thick ( this is in total but you can easily get several smaller bits of steel as long as they are no shorter than 14 Cm and no less wide than 10 Cm )
-firm foam sheet A4 sized and at least 1 cm thick
-epoxy resin (I used Araldite)
-fairly tough cloth ( can use thick clothing etc)
- small neodymium magnet


Tools:
- metal file
-hacksaw
-glue gun
-black spray paint (optional)
-gun to test !

Thanks, the bulletproof iPhone case makes my life so much easier.

The metal with the red circle does not show signs of any bullet impacts. A .22lr would tear straight through that sheet steel, padding, and your phone. sorry. good luck

What about the front and have you tested with rifles ?

So, it will save your ear if you get shot mid-call?

And it would probably hurt your hand.
and your skull. kinetic energy is a jerk :p
Not to be rude or anything, but if you claim something to be bullet proof , it actually should be. 7.62 round would turn that into scrap. Just consider the fact that if you can cut the metal you used to make it with scissors it's probably not bullet proof, ( or even stomp proof)
22 rifle vs road sign. which is made of thicker metal than your case. hmm, lest we throw kinetic energy out the window...

also, if your being shot at, chances are you made allot of bad decisions consecutively, if your not government personnel, in that case if they happen to get your phone, your employer will more than likely compensate you for damages anyways.
I agree. This may be able to stop a .22, or maybe even a 9mm, but anything bigger will tear right through. Also, you've made it to be hammer proof etc. There are already cases made out there that are half as slim and can protect even more.
Half as slim?That would be twice as thick.
lol oops...
I'm sure there are cases out there that do the same, but wouldn't that defeat 90% of this page? I mean, it is all about home projects. Mainly stuff you can find in stores.

Good work man. Just one thing. If you haven't shot at it, don't say it's bulletproof. False advertising and all.

I do appreciate the time and thought that has been put into this, but I agree with the criticism over false advertising. I don't have the silly thought that bullet proof requires one to fire the largest common calibre found in war, but some evidence is required, but we have not seen the .22 test yet. The deformation, and lead splatter would be visually (and probably functionally) significant. A solid metal box would also act as a Faraday cage and significantly reduce the signal.
yeah you can buy something similar or better - but doesn't that cover about 90% of the instructables out there?
Chuckle , there's always a bigger/stronger gun , where do you stop ? After all it is just a phone . The nice thing about the case is it's a little big and heavy making you spend less time talking and giving you more time to pay attention whats going on around you . Called situational awareness .
Guys, I really cannot believe how pedantic you are all being. If it stops a low calibre bullet, it is bullet-proof. How many readers here are going to be facing high calibre rounds anyway? When we say something is bullet-proof it is a euphemism, usually, for "very tough"....and clearly this design is very tough.

And so what if there are other things out there that do it better? The whole point of Instructables is to do it yourself. Give credit where it is due.
1) You can cut kevlar with scissors. It's all about composition. Just as a glass block can support hundreds of pounds/kilos under compression but be shattered by a few pounds concentrated by a punch, Certain types and weaves of kevlar stop different types of penetrations e.g. vest that stop bullets won't stop knives. Prison guards wear different vest than do police or soldiers because the former faces knives and the latter guns.

2) Technically, no one claims to be "bullet proof." If you look at the trade materials, the legally approved speak for all types of armoring is "resistant." The reason is that if you want to, you can shoot through anything. "Proof" implies impervious and there is no such thing. In common speech, however, "bullet proof" is used.

3) A standard civilian deer rifle with a hollow point hunting round will punch through almost every body armor out there. If you use a hardened bullet, easily made, it will punch through most of a steel engine block. Yet in common speech we don't say, "whoa, you can't call that police vest 'bullet proof' because there are 3 million civilian weapons in the US alone that can shoot through it front to back."

3) Even if you restrict the issue to just a single bullet, at a single caliber fired from a single model of weapon, there will be in the real world a vast spread in the energy and thus lethality of all the bullets flying around a battle field. The penetrating power of rounds is a laboratory abstraction set under fixed ranges, temperatures, pressures, winds, DISTANCES, age of munitions and maintenance of the weapon. In the real world, you deal with spent shots over distance, ricochets, crappy ammo and guns that haven't been cleaned since Eisenhower is president.

That's why there are so many documented instances of people being saved by bibles, badges, dog tags etc. The round the caught didn't have the energy to penetrate such an object under those conditions even though in the lab, it probably would have.

4) The utility of armor is all about what it protects. Not even tanks are equally armored all around. You might reflect that armor disappeared almost entirely from 19th century battle fields because of all the high energy line of sight shots would punch through any armor a man could carry. Armor only returned in mid-WWI in the form of a helmet whose sole intent was to protect against low-mass, low-velocity shrapnel. Any military bullet of the age would go right through any helmet, yet soldiers still found the minimal, single purpose protection it provided worth the humping weight and they have ever since.

Likewise, even a small increase in protection for a vital tool like a smart phone is worth the effort. Just because it won't stop laboratory ideal common rounds make it useless.

This is a very useful field expedient.
So a class II bulletproof vest isn't? Really? (the joys of youth and 'internet experts')
(most BP vest are NOT knife proof)
If it can stop a low caliber bullet only then I would say it is more of a Flak Case. Also to those saying how many people need to worry about rifle rounds... How many people need a "bullet proof" iphone case... People being shot at that's who.
Very cool but I wonder how a phone would withstand the G-force impact of a bullet strike. I think it would crack the phone from the impact alone. I saw that there is foam within the case, but I still am concerned that the foam would lack the dampening effect needed to save the phone. Still very cool though.

To all those saying this isn't bullet proof, you don't know what you are saying. The term bullet proof doesn't mean "stop everything". It means the item is rated to stop whatever the maker claims it will stop. The term originates from testing medieval armor vs. bullets of the time. The maker would prove that his armor would stop a bullet by shooting it. The dent from the bullet would be left as the proofing mark. Even if this thing will only stop a .22 pistol, it is still bullet proof.
bullet proof does in fact mean it will stop any bullet .i think bullet resistant would be a more accurate description .as that is the term used by the armor manufacturers
awesome now this should be put in stores

your very very welcome and god bless america
I haven't read all of the comments. Have you considered ceramic plates. It only has to work once anyway. The newer materials used for vests use ceramic plates under the kevlar body armor. As to the composition of the plates I have no idea. The idea is to absorb the impact and spread out the effect and not stopping the round completely.

Apparently the D3o stuff isn't sold but they might consider a collaboration I suppose. Create a ceramic plate box to cover the device and maybe they would be interested in determining if the D3o will protect the plates. Be interesting to see if the D3o stuff has any ballistic properties. Seems like a lot of motorcross gear is made from the stuff.
I checked Wikipedia and got this: A ceramic is a non-metallic, inorganic material, used to mould items or articles. Ceramics consist of clay soil, to help with the remoulding, and other non-metallic inorganic substances.Ceramic plates, typically composed of boron carbide or near variants, are very popular in military application. These materials offer very high ballistic value. However, they do not do very well at dispersing blunt trauma. As a result they are often backed with materials like aramid fabrics, high density plastics, and/or metals.Ceramic plates are made of clay, and some other non-metallic inorganic materials.

Ceramics can be molded and fired. They aren't very durable so I'm not sure how well it would work. Maybe a covering of the new D3o plastic to protect the ceramic plate. 
Aparrently at least some armour aplications use alumina (aluminium oxide) ceramic, the other aplications I know of for this is for TIG torch nozzles and I believe that some sparkplugs use it as insultaion between the threaded outside and the electrode inside.
If you increased the padding inside this would work great for portable hard drives as well.

Well, nice with getting the "bulletproof" to be literal, but what about your phone's reception?
I mean, it makes no sense to bother doing this, if the phone stops being a phone and becomes ballast.
antioch1 year ago
Simple, cheap, more or less everyday objects or easily obtainable materials. Fun idea and well done instructable.
It is beyond me how it attracted so many dimwitted criticisms. Does maybe a faible for firearms go with a lack of wits?
Anyway, keep on bulletproofing!

veeguy, perhaps you should read it again. There are FIVE layers of 3mm plate ....

Here, I'll help ..

4) when you have your sides all folded up you must then glue (using Araldite ) in place a rectangle of thick cloth 13 x 6 Cm onto the base of the shape with folded sides.
5) now on top of this cloth glue in place one of your rectangular metal plates
6) again on top of this plate glue a rectangle of thick cloth and continue this pattern until all 5 of your plates and all 6 of your cloth pieces are sandwiched together. This constant layering of metal will slow down the bullet while the cloth will be reducing the force of the impact on your phone.
Why would you want to protect an iPhone in the first place?
;P

This is a nice instructable for a heavy duty iphone case. The 3mm mild steel would work out to 10 gauge metal, quite a sturdy material. My problem comes in where the author implies this would withstand a "low caliber bullet". It will not. My Daisy 880 pellet rifle will shoot a .177 caliber hunting pellet through both sides of this case and the phone inside it. If you want to build this great ultra heavy duty phone case, go for it, but don't assume it will stop a projectile, especially one fired by a real gun. This is how people get hurt or killed.
