Picture of Iron Man MkV Arc Reactor

This reactor, like my previous reactor, is available for purchase, visit my website and email me from there, the paypal links are now available for both styles of arc reactor

Feb 2012 Green Arcs Kit's and Assembled
Having just seen the trailer for the new avengers film out this year I'm now pleased to offer the MkV in green for kit versions and fully assembled versions

May 2010  DIY Kit available
This arc reactor is soon to be made 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.

Step 1: Tools and Materials

What Kind Of LEDs Did You Use??

can you tell me how you cutted it??? thanks
msraynsford (author)  Robine007hawk2 years ago
Scalpel, but now I laser cut them.
EdisonGuo2 years ago
Could u please tell me how u wired the LEDs?u stuck them on the wood and then used solder iron right?
How the heck did you cut that thing out. I have tried with the exact same dvd case and a brand new exacto knife blade. I have also tried a dremmel, but I couldn't get the same accuracy. If you have any tips of cut the template out of the plastic please respond
msraynsford (author)  cheesecurd18992 years ago
Cut slowly with multiple passes and a scalpel will get through it eventually. Also note the difference between a scalpel and an exacto knife. Scalpel blades are uber sharp, go careful or lose a finger. http://en.wikipedia.org/wiki/Scalpel

How do I determine the anode and cathode on the SMD LEDs?
msraynsford (author)  buick882 years ago
The cathode has a notch off one of the corners
Oof, thank you so much. You wouldn't believe what a hard piece of information that was to track down.
3 Questions:
1 Why do you need two types of resistors and 2: where did you get that twisted wire and finally 3: what do u do with the heat shrink?
msraynsford (author)  PaulioAwesome3 years ago
1. Because the middle LED is on it's own, all the others are in pairs.
2. Take red and black wire and twist it (you can use a drill to twist it really quickly)
3. The heatshrink covers the electrical joins in the wire join and stops your battery shorting out
This is probably going to seem like a derp question, but is polymorph plastic the same as friendly plastic? I've been looking it up and have seen people saying it's the same thing or it's completely different. Is InstaMorph the same thing?

Nice Reactor. But i kinda lack of the wood to hold the LEDs. Can anybody tell me other materials that can hold the Leds in place. I thought of foam but if solder, it will give out some Chemical thing........
msraynsford (author)  DemonKing973 years ago
Wood is handy because it doesnt melt and it's easy to get hold of.

The much better option is a PCB (like the ones I include in my kits)

This is an awesome tutorial! Any chance of finishing it?
msraynsford (author)  luseylottay3 years ago
This one has kinda had it's day now, I keep meaning to write one based solely upon the kit. Now that there is a PCB for the electronics and a laser cutter to make the details the standard has improved quite a lot and things are quite different
Aww, okay then.
sweet arc reactor. you know what I going to make it
Awesome arc reactor

where can i find the leds you used and how do i circuit them?

How do you suggest going about attaching this thing to your chest? I was thinking a necklace, sown onto a shirt, or possibly some sort of body glue. What do you think?
I found on other instructables they stick it on belts

Would glass work for the light to shine through on the front because i have a piece of glass that is the perfect size and shape.

interested in this thing give more details about it

Lots more details can be found here https://sites.google.com/site/msraynsford/ironmanarcreactors

ok, couple of questions. they look to be wired in series, do you need the resistors to keep them all the same brightness or can you wire them in series without any resistors and have them all the same brightness? would mounting them on balsa wood work? thats all, thanks
just kinda cool but mine is better
msraynsford (author)  Warmachine115 years ago
Sounds like a good challenge to me, I look forward to reading your instructable then.
Where's the rest of the instructable?
msraynsford (author)  MITisNOTHINGtoME5 years ago
Actually, you are right it does seem like a short instructable. It's currently more of a "How to improve the Mk1 process" instructable than a "How to build a MkV". Stay Tuned, will be improving shortly which will be of special interest to the people who've just bought MkV kits

Do you have to use surface mount leds or would regular ones work?
You can use standard LED's but as msraynsford said they have a lot more depth than the surface mount led's....I made a couple of arc reactors using some white water clear led's and just made sure to sand them down so that the light was properly diffused and they looked pretty decent....if you would like to see how a sanded led looks in comparison here is how mine turned out www.afreeland.com/node/29 ...hopefully this helps

I also must say that this is an amazing tutorial and must admit that your work is amazing!!!! Keep the great LED content coming =)
thanks, looks awesome.
msraynsford (author)  trauma-d5 years ago
Surface mount LED's generally have a wider field for the light it outputs and are only 2mm thick meaning the whole thing can be thinner
ok great, when will the pay pal link be up for the mkV kit? you did a really excellent job putting these together
msraynsford (author)  ITAstallion135 years ago
The MkV kits are now available, sorry for not getting them sorted faster but had some issue with getting the parts laser cut (yes, laser cut for much better accuracy than my Mk1's)
