A long time in the making but I'm finally pleased to announce that this arc has be superseded by a newer design which I'm calling the MkII. The MkII features laser cut parts from a metallic coloured acrylic and avoid copious hours of bending and cutting small pieces of wire. These are available as kits of full arcs from my website.

I've updated this arc reactor design based on the recently released sequel. This newer instructable features better tips on how to make the fiddly parts and an easier to build design.

The Mk1 arc reactor is now available in kit format. So if you ever wanted to make your own but couldn't make the parts yourself, now you can buy a kit containing all the parts, instructions and shaped polymorph.

Iron Man Arc Reactor
This instructable is one of two parts detailing how to build an arc reactor and an iron man mask. Both work together but are written as seperate instructables for clarity. This part is for the Arc Reactor the Iron Man Mask can be found here: http://www.instructables.com/id/How-to-make-an-Iron-Man-Mask/

My costume was built for a fancy dress party but it is so cool I'm thinking about wearing it else where.

First I needed something to copy, I work best when I'm copying someone elses ideas so I used the following screen shot of Tony Stark in Iron man as a basis for my arc reactor. As you can see it has 10 well defined sections and a glowing centre. I'm also going to use the sleeveless T-shirt and I attempted to grow my own facial hair in time for the party.

I'm rather pleased at my attempt to make the arc reactor and very happy with the segments of light that eminate from it. I'd also like to pay respects to the other arc light reactor on instructables, imagine my horror as the weekly round up arrives in my inbox only find out that I had been beaten to the write up for the same project.

Update - September 2010

Halloween is coming rounnd again and yes I'm still making them so order now in time for halloween.

"Will you make me one of these?"
I finally got round to making myself a webpage about these and all of my other projects, it's still a work in progress but I think it covers the basics for now.

"I live in X where can I buy Polymorph From?"
I get this question a lot, sadly I don't live in x so my insight is never very helpful. Google is your friend as always but if that fails or you don't feel you can create a mould to shape the polymorph contact me and I will happily sell you some polymorph and/or a shaped disk.

Step 1: The materials

I wanted to make something a bit more substantial for this project and I remembered I had some suitable plastic in my cupboard. This is the key compenent for the project. This stuff is called polymorph and can be bought from places such as Ebay. It's a thermal plastic that melts around 60 degrees C and it becomes something resembling plastacine. From there it is simple to mold it into the desired shapes.

The next thing we will need is a light source. I wanted the whole thing to be quite thin when it was finished and sat on my chest so I opted for some surface mount white LEDs. Surface mount LED's have a very wide viewing angle and being white they produce quite a lot of light so they are perfect for this application. I bought mine from Rapid Electronics, I would plug them with a link but they charged me more for P&P on the LED's than the LED's cost, so I'm not going to. These LED's are in a PLCC 2 package which means they are still large enough to be soldered by hand.

You may also want some surface mount resistors to go with those LEDs. I used the amazing program at http://LEDCalc.com/ to work out exactly which values I need. As I am running these LED's from a 9V battery and wanted 20mA of current to flow throw them. They suggested how exactly they should be wired and what values I needed (incidently I have stolen the circuit diagram from them too). For my LED's I required 5x 180 Ohm resistors and 1x 330Ohm resistor.

I mounted the LED's on a peice of plywood, anything will do as you are glueing the surface mount components down for ease of soldering. A 9V battery and battery clip are providing the power for the system. These can be bought from any electrical store as required.

Finally you'll need some wire for the detailed decoration. Wire coathangers could be used but I used tin copper wire of 22 AWG gauge. There is nothin special about the wire, it's just hard finding something chunky enough for the job.

Stark seems to use Palladium isotope from his missiles as the reactor's fuel. Once the reaction starts, the energy harnessed is enourmous at 3 GJ/s or equivalent to 3 GW. (That's more than twice energy required for time-travelling (which needed only 1.21 GW of power) in Back to the Future films).

This power can be used to power up his suit for a long time for his enhanced reactor, not the first one.

To make this extremely efficient power supply, I believe we can. And I believe it is possible. But I think that it can be done only in a few hundred years.

The movie is purely fictional and I believe that the writer are just fantasizing about the perfect energy source. (Dreams mostly become true eventually). If we are living in 19th century, people won't believe you if you can send sound wave and pictures accross the globe. Now, it's possible. So what makes an arc reactor impossible?

It can be done. But not in recent time.

but is it possible if the reactor power source being replaced by a car battery?
Alex Jalland says: Feb 11, 2012. 8:45 AM
what does a nine volt battery look like or what is its symbol?

pipsqueakboy in reply to Alex JallandAug 7, 2012. 4:45 PM
Its the rectangular one.

you sure look cute
Warmachine11 in reply to piratekittenJun 10, 2010. 9:27 AM
cool im making 1
maccro in reply to piratekittenJun 18, 2008. 8:29 AM
Nice...so now everyone has an excuse to stare at your chest. "Wow, nice arc reactor!".
computer_guy in reply to maccroAug 19, 2009. 11:16 AM
AHA HA HA AH. Nice.
TheSniper says: Oct 31, 2011. 3:39 PM
How many would you say you've made thus far, msraynsford?
msraynsford (author) in reply to TheSniperNov 1, 2011. 1:43 AM
A better question would be "how many people have managed to follow these instructions to make their own?"
I've made a fair few now but I did post this several years ago so it's a slow and steady trickle.
Caleb Nehrbass says: Oct 14, 2011. 6:01 PM
What I never understood about iron man was why did he not get the shrapnel removed when he got back? He walked around with a power source in his chest...
Caleb Nehrbass says: Oct 14, 2011. 1:45 PM
Is there a type of clear polymorph?

go on google and look up"circuitry basics" or something.
i had half a course in high school on it and i was probably not there often before i dropped out.
easy stuff
Colonel88 says: Feb 19, 2011. 6:23 PM
Quick question, how deep is the wood cutout thing? Im guessing around 10 mm deep, then some 5 mm for the other portions to stick out.
althor015 says: Feb 19, 2011. 2:55 PM
Hope some one is still reading these and commenting on them. I am trying to build one of these and am unsure of the wiring schematic.

Which symbols are the resistors and which the lights and how do the outer wires follow the ring?

Bah! Wish I had taken electronics classes!
msraynsford (author) in reply to althor015Feb 19, 2011. 3:09 PM
Still reading and commenting, sadly it sounds like you'd be better off googling for some beginner electronics tutorials.
ironman22 says: Feb 8, 2011. 7:41 AM
nice job man i would like to try to make one like these
itjmiller says: Jan 5, 2011. 2:07 PM
I'm very new to this, but I have to ask. Are the resistors supposed to be on the negative side of the circuit? Do resistors really work that way? In the wiring diagram, it shows that the positive current goes through the LED, then through the resistor, then to ground. Is this a mistake, or does it not matter which side of the LED they are placed. The first diagram (from ledcalc.com) shows the resistors on the positive side....

How many grams/ounces of polymorph did you use?
msraynsford (author) in reply to MrEvolution47Nov 15, 2010. 12:12 AM
I use 35g of polymorph but this will obviously depend on your mould and I'm managed to eek mine down to the smallest amount possible now.
dalangalma says: May 31, 2008. 11:52 PM
I have a question - where are the resistors in this photo? Are they the little bumps next to each LED? If so, are they soldered together or did you just glue them in contact? Fantastic instructable, by the way. I'm really excited to try it myself.
msraynsford (author) in reply to dalangalmaJun 1, 2008. 1:27 AM
They are the little bumps next to each LED. I pressed the led and the bump into blue tac to hold them roughly in the right place before I soldered them together. It makes it a darn sight easier with these small components.
c_nic in reply to msraynsfordOct 26, 2010. 10:08 AM
so yeahhh...my iron decided to not work right plus i couldnt find a tip sharp enough for this small of work. couldnt keep a tin for anything. ended up killing 2 leds.

shouldve just bought the complete thing. there went 30 bucks. haha my suggestion? buy the complete and leave it to the professional. :S
ramboboy says: Jun 13, 2010. 7:29 PM
awesome what about the batteries
Darthscout in reply to ramboboyOct 22, 2010. 2:28 PM
those you put in an Altoids container or anything else that can house 1 or 2 9 volt batteres

Neogarex says: Oct 11, 2010. 7:29 PM
thanks
Jason Amigo says: Aug 2, 2010. 6:59 AM
Since you used one resistor for every two LEDs, did you double the ohms of the resistors?
HobbitComedian says: Jun 22, 2010. 5:36 PM
Here is an image of an arc reactor that I made using this Instructable as a guide. My more complete build out instructions can be found here: http://www.instamorph.com/?p=14 Used a new brand of polymorph called InstaMorph, which you can buy on Amazon or their website. http://www.instamorph.com They are Prime eligible too which was nice since I got free two day shipping as a Prime member The LEDs I got a Fry's electronics. They have the perfect stick on surfacemount LEDs for this project.

spaceboy22 in reply to HobbitComedianJun 22, 2010. 6:33 PM
cool where did u buy everything
HobbitComedian in reply to spaceboy22Jun 22, 2010. 10:03 PM
I got the outer ring (plumbing fixture), plastic washer and copper wire at the hardware store.The batteries, clip, and LEDs I got at Frys Electronics. The plastic I got from http://www.InstaMorph.com. The harness I made from velcro and elastic fabric from Jo Ann's Crafts. Hope that helps.
oud25 says: Jun 17, 2010. 5:17 PM
where did u buy the individual smd leds
shilicious says: Jun 12, 2010. 10:10 PM
Is there a way to make the LEDs pulse? I've seen some other versions of the arc reactor that fluctuated gently similar to the way Tony's does, and I'm not handy enough to know how to do so. Any input would be great! Thanks. :]
