Homemade Iron Man Arc Reactor Mark 1

It is not a secret that I am a huge Iron Man fan. 
I fulfilled myself a dream building my own Arc Reactor!

Click here to see the rest!
At the beginning I designed all the parts in Adobe Illustrator. I cut them out of 2mm thick acrylic with the help of a lasercutter. 

I am currently giving away the plans in exchange for donations for my website! I am also giving away a complete set of the lasercut parts in exchange for a donation to my website! Drop me an e-mail under the contact section!
If you’re looking for a demonstration video scroll down to the bottom of the page!

These are the basic components. I etched a dot matrix onto some parts in order to disperse the led light better. Most background lights have these dots on them. Add some black, silver and copper paint:

Clip together two of the outer rings with the spacers seen above in the left top corner:

Starts looking a bit more like an Arc Reactor from Iron Man, doesn’t it? 
Now I added the background plates for the reactor’s coils.

 The Arc Reactor’s core consits of three rings and the silver mesh:

 With the help of some paint and aluminum a fourth ring is held right above the core.

 Here you can see the Arc Reactor’s inner parts fully assembled:

The next step was winding the coils! The wire I used for this task is coated 0,8 mm thick copper wire.

Additionally I added a layer of paper for better reflection of the blue Leds. There are 10 coils on the Arc Reactor. 5 have blue Leds beneath them. I inserted them through a little slot from bottom into the acrylic and then wound the wire around it.

All Leds need some resistors! I allways wired up two leds in parallel and added the right resistor. For finishing the baseplate watch the video below. 5 Leds go into the ring and 3 Leds go into the baseplate’s spaces. Wire everything up, glue it together and your homemade Iron Man Arc Reactor is ready for the next costume party! 

Here is the video for some more details:

I am currently giving away plans and parts in exchange for some donations! Feel free to contact me!



  1. how much would you sell it for cuz tht looks amazing guys. you realy are the best. tell you what i think i would buy almost anything of here. 🙂

  2. your site Awesome… So many Interesting things are their.. i'm start to make that Iron Man Reactor… Now am sick 2 days after i will start to make it. But this site very very very Good… i love it..

  3. It seems you have a great mind for creative invention – could be a Real live Tony Stark…
    been watching you since the coilgun post in 2011, quite sure you now have enough models and prototypes to build an impressive resume for the right *company, also pretty sure *others have taken notice – so take care to make cautious decisions when speaking to individuals that may be over enthusiastic towards using tech for *covert-stealth *projects… there are many who see talent and intelligence of certain levels as a threat, might behoove one to cultivate a healthy degree of suspicious awareness. -' ' >>_ _<< ; * ~ ~_
    But keep having fun, looking forward to seeing more cool stuff from you!

  4. Iron Man rules!!!! I was researching how to build an arc reactor for my 8yr old she has asked to be iron man this year so I'm trying to make her the suit and I thought I would try to build an arc reactor. As I was watching you tube I ran across your website and I was wondering if you sell these and how much it would be?

  5. I know how to build a real, working arc reactor, but it will be expensive. about $500,000. But the power it gives off could power an entire city for 200 years, and by then it will be cheaper to build. donations will help. Contact me to donate.

  6. Palladium could work as the power source (Along with other stuff). It might take a team 2 or 3 years to finish this project. An individual would take over 10 years!

  7. @John Curtin, I know how to build a real, working arc reactor, but it will be expensive. about $500,000. But the power it gives off could power an entire city for 200 years, and by then it will be cheaper to build. donations will help. (I could give you the prototype. But this might not be what you meant. 🙂 )

  8. I'm titillated by the notion of working with you. I'm going to ditch these clowns; I'll see you up on the roof in five minutes.
