"Whoever holds this hammer, if he be worthy, shall possess the power of...THOR"  


Hi, welcome to my instructable.
For me, super hero movies were always an inspiration. I always wanted to build technical toys which could help me feel alike to those heros. When I saw the feature "THOR" for the first time, I very much liked his hammer. That's why I decided to build one for myself and of course share with you the full step by step instructable. 
I hope you will enjoy it!

Marvel Rules!

Step 1: The idea, PDF instructions and printouts

The real Thor hammer allows you to fly, throw lightnings and so and so on.
Ours will be a bit simpler compared to the original but it will meet at least a few points.
  • It must be strong to survive punching and hitting, but on the other hand should be light enough for easy handling
  • It must look like Thor's hammer
  • It must be done out of a dying star
  • It must come to life on after you touch it
  • It must throw or be thrown…
I decided to have the hammer made out of steel because it will make the project simpler. 
Steel is solid so the hammer will get stronger, Mjolnir was also made out of metal, so mine is going to look like the real one.
All the elements in the universe except hydrogen, helium, lithium and beryllium where made in stars, so my Mjolnir is going to be made out of a dead star!!
The last two points I'm going to solve with electronics.
Throwing my hammer wouldn't be very efficient, since it would (probably) not return to its master by itself.
That is why i found another solution:
Instead of throwing Mjolnir, I'm throwing pieces of metal that are connected to the hammer. How? By means of an electro magnet.
Switched on it will "grab" metal objects, and when switched off – release them again.
If one circles around oneself, you build up a lot of momentum (like in the Olympic hammer throw), but you won't let go of the hammer, but of the metal pieces temporarily connected.
Enough of theory, lets collect the parts and build it!

i think its a cool hammer. good job!

Just wanted to mention, there is no such thing as centrifugal force, its centripetal force. Otherwise, great instructible and project!
asavage2 says: Sep 16, 2012. 2:41 AM
Actually, both exist. Centrifugal force causes a motion from the centre of a revolving object, directly toward the extremes of the object. Centripetal force causes an abject to follow a predefined path, like those "loop the loop" toy cars.

Already stated by Berkenridge but whatever, its still really funny.

Thanks!
In Non Inertial reference frame it is called centrifugal force but in inertial reference frame it's called centripetal. And both are correct and existing!

define working....
xinistrom says: Sep 25, 2011. 1:07 PM
the real hammer is 1 handed, isnt it? :P
shadow wave rider says: Jul 11, 2011. 7:59 PM
how wide is the hole you drillled in the handle for the micro-switch for the electro-magnet? cool video too. i like the bit when you smash up the chair. lol, die chair, die!
jeremyzoo (author) says: Aug 4, 2011. 2:36 AM
Hi mr awesome
the hole for the micro-switch is 8 mm wide
Thanks for following
And the chair is actually an old barbeque grill :)
Circus Bear says: Jul 9, 2011. 12:02 PM
I think it would look cool if you made the grip out of a leather strip running all the way up the handle, with a loop-strap.
tacamaral says: Jul 8, 2011. 10:37 AM
Man, this is pretty nice! Congrats!

I want to make one myself, but on a different style - I'm going to use zamak and make a solid head. I'm going to make a more realistic hammer.

Anyway, comments on your project:

Nice, very nice, as I said. You could cover the handle with leather and put some sort of button at the end of the handle - like an antler or bone plug. It would look very nice.

A leather loop, as said, would also be closer to the original and avoid it slipping off your hands (or are you the real Thor? : ) and flying off into the sky.

The writing can also be done with electro-engraving. Pretty easy for you, obviously, and the results are very good.

The video is really funny!

Well, anyway, I think it's an awesome project! : )
jeremyzoo (author) says: Jul 9, 2011. 1:34 AM
Thanks!

I have never heard about electro-engraving. I must try it.
by the way please share some pics after you have finished working on your hammer
JuCo says: Jul 4, 2011. 9:43 PM
1) i love the enthusiasm in the video. you look like you were having a ton of fun.

2) depending on how strong you can make that magnet, you could get it to mimic the whole "only the worthy can pick up mjolnir" thing.

the magnet pins it to the ground, the "unworthy" can't move it (or, at least struggle picking it up). then the "worthy" (you and whoever you decide to tell about the hidden switch that turns off the magnet) walk up and pick it up with ease.

the only problem with this is having a heavy enough ferrous object to set the hammer on to begin with, but whatever... it'd be worth it.
jeremyzoo (author) says: Jul 5, 2011. 1:13 AM
Thanks for the ideas! I'm happy you enjoyed the clip.

I think i found a solution how to make this "worth it" work.
I thought about two contacts on the handle which i could easily connect with my hand and close the circuit. I could ad some transistors which would open by some voltage. Since the body has a big resistance the Mjolnir would never switch on so
I would use a glove with wires woven in, which then would have a smaller resistance than the hand, so i would be the only one worth it.

such a scene in which my friends are trying to lift the hammer off this metal peace is certainly missing!

I'm always glad for new ideas, if you have some more please do share them! :)
Madrigorne says: Jul 8, 2011. 2:32 AM
wear a ring that can connect the circuit, press the ring against the two contact points - voila
RedneckEngineer says: Jul 5, 2011. 4:33 AM
Instead of a glove why not finish it with a leather loop that wraps around your wrist. The switch could be a contact switch on the inside of the loop and your wrist completes the circut.
Just an idea.

Either way this does need a leather loop to help you hold the thing when swinging it in circles. And Thor did use it if my memory serves from my youth comic obsession.
iminthebathroom says: Jul 5, 2011. 3:04 AM
like the idea of the glove but... did Thor wear gloves? Haven't seen the movie yet and it has been a while since I've seen the comics, so I probably shouldn't bother commenting like this. Another way perhaps would be to figure out where your ring finger would be on the handle, then put 2 conductive thin conductive rings on the handle, somewhat close together. Slip a conductive ring on your finger, pick it up and complete the circuit. Was also thinking couldn't you make the handle out of ferrous metal, then when you do your copper wrapped handle, hook the 2 ends up to your battery pack and it would be your electromagnet. Either way, this is a an awesome instructable.
jeremyzoo (author) says: Jul 5, 2011. 4:43 AM
I'm happy you like my instructable.
You are right Thor did not wear a glove. The ring idea is great because nobody will suspect that this is the solution to switch on the Mjolnir.

My handle is made out of steel so it is ferrous and I have even tried to make an electromagnet out of my handle with the copper wire I used later for the deco, but the amount of it gave a week result and I had no more time to buy a new thiner and longer one. But you are right it would work right as well.

I wonder if this wrapped copper wire on the handle could work as the electromagnet and as the coil for the tesla coil. I have no idea about this generator.
MaXoR says: Jul 8, 2011. 12:58 PM
Umm as soon as you said "Tesla coil" you *sparked* my attention.... Pun intended lol, I cannot even begin to imagine the technical challenges associated with trying to ground yourself apart from the 10,000+ volts.

You're only hope is a gauntlet (Glove), with sleeve, that has wires woven into it to create a faraday cage out of your arm which is wielding the hammer of power!

....And to boot, you would then have these crazy arcs flowing up your arm, and towards any ferrous object near to you (If you could juice the coil enough that is)

Dangerous yes...but isn't anything truly spectacular going to be anyways?
JuCo says: Jul 5, 2011. 8:25 PM
i second (or third) the ring idea... and i second a strap on the end of the handle. if that thing gets away from you, it will definitely do some damage.
wobbler says: Jul 8, 2011. 1:39 AM
You could have at least added wings to your hat (although I noticed it did fly off at one point)! Or is that your next Instructible?

Or you could have just put a pigeon under your cap?

;o)
antoman11 says: Jul 7, 2011. 8:27 PM
That is actually... INCREDIBLY AWESOME!!!

Fantastic job, and your video made me crack up laughing
jeremyzoo (author) says: Jul 8, 2011. 1:21 AM
Thank you very much!
instructimaster says: Jul 7, 2011. 5:37 PM
So it doesn't summon lightning?? :-(
Oh, well... We'll get there eventually.

Nice thinking though! :-)
jeremyzoo (author) says: Jul 8, 2011. 12:55 AM
Thanx!

Lightnings are certainly missing!
I will have to work on it!
smckdwnfan316 says: Jul 7, 2011. 2:06 PM
Looks pretty cool man, nice work! Keep up the wicked Marvel props :D
Only things that would be good to change is..
1. The straps on the handle being made from leather and having them go all the way to the top and a small loop on the bottom
2. The inscription on just one side saying "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor"

About the gloves, only seen him wear them in the Ulimates series and was with the other version of Mjolnir

I think the power possessed at the moment is more like Magneto than Thors good luck with creating a mini tesla coil that you can control the direction with.. That would be freakin awesome
jeremyzoo (author) says: Jul 8, 2011. 12:26 AM
Thanks man!

1.I have bought a leather strap to wrap around the handle, but I decided to use the copper wire because of its cool steam punk look. The loop in the end of the handle I'm still going to make.

2.There is a inscription on both sides in the bottom. You can see it in the beggining of the clip. It says "Whosoever holds this hammer,wields the power of Thor" I changed the inscription because of lack of space.

antoman11 says: Jul 7, 2011. 8:31 PM
Personally I would not have put the electromagnet in, and instead put a block of redgum wood in the centre core of the hammer. The metal covers would hard drill in, and have a much more stable hammer, but that's just my opinion

Although the electromagnet is pretty cool, especially with the metal throwing ability!
gary.918 says: Jul 7, 2011. 9:19 AM
jery good, keep on buliding
jeremyzoo (author) says: Jul 7, 2011. 9:25 AM
Thanks! I certainly will!
tinker234 says: Jul 4, 2011. 8:06 PM
to shoot lighting bolts add tesla coil also did yopu know you are 95 percent stardust fun fact
jeremyzoo (author) says: Jul 5, 2011. 2:01 AM
Thanks for your comment!
I think your idea might work. If not tesla coil then maybe a van de graaff generator like in this instructable:
http://www.instructables.com/id/DIY-Lightning-Wand-a-Handheld-Van-de-Graaff-Genera/
I'm going soon on vacation so I will have a lot of time to think on my project and new ideas.

tinker234 says: Jul 5, 2011. 10:00 AM
ok so what about a something to fly maybe
jeremyzoo (author) says: Jul 5, 2011. 10:47 AM
I don't know what do you mean. Check 0:46 in the video, I'm puling big metal washers which I'm later throwing. The flying washer you can see in 0:49 in the clip.
It is one of the main functions of my hammer.
tinker234 says: Jul 5, 2011. 2:20 PM
i know im asking how to make it fly humans
jeremyzoo (author) says: Jul 6, 2011. 12:10 PM
This sounds difficult!
tinker234 says: Jul 6, 2011. 2:29 PM
beyond my skill level
Arano says: Jul 5, 2011. 11:06 AM
really nice work, but in my opinion the handle is to long.... according to the legend (as written in the Edda) loki caused the steel to cool down a little while the smith was working on the handle and the handle turned out shorter than it should
jeremyzoo (author) says: Jul 5, 2011. 1:03 PM
Thanx!
Behind my long handle is also a story. I took a longer one because i thought: when the handle will be to short it will stay like this for ever, so i took a longer pipe for future changes. I wanted to have the handle short (as you can see: 2 step/ 1st Pict), but the first time I held the finished hammer the long handle felt so good in my hands that I decidet to stay with it.
Infinite_minus_zero says: Jul 5, 2011. 7:45 AM
Awesome!! uve seen some instructables wondering how to do them, but this is very clear! plenty of pictures and very discriptive. i could actually make this if i had the time and money! plus i love the idea! i would never have thought of makingthis, though if i had i wouldnt never of toughtr of the magnet!
jeremyzoo (author) says: Jul 5, 2011. 11:00 AM
Thx! If you have no money you could do part of the hammer out of wood. Just the top wall of the hammer box must be done out of steel to "conduct" the magnetic field. It wont be as solid as steel but other functions will be working.
Infinite_minus_zero says: Jul 5, 2011. 11:19 AM
good idea! I could spray paint it metalic so it looks like metal, and im sure i could find a random steel bar somewhere... :D
