When the Green Lantern movie came out earlier this year Toys R Us started selling a decent looking replica ring for only $10- here's how to make the ring look a bit more heroic by installing a LED and making it more accurate to the movie ring. It's a fair bit of work but for GL fans it's worth the effort!

Step 1: Tools and Materials

This instructable is a further development of my previous Green Lantern ring tutorial seen here-

The wax carving and resin casting are the same process so I won't repeat them here. There is some very basic soldering involved and some Dremel work but it's pretty straight forward. Be sure to click on the "i" symbol to see the high res images.

So here's what you need to modify your ring:

Dremel tool with various burrs
Soldering iron
Jewler's wax- http://www.ottofrei.com/store/product.php?productid=1077&cat=1868&page=1
Silicone RTV molding compound- http://www.alumilite.com/ProdDetail.cfm?Category=Silicone%20Rubber&Name=High%20Strength%203
Casting resin- http://www.alumilite.com/ProdDetail.cfm?Category=Casting%20Resins&Name=Alumilite%20Regular
Sharpie pen
Kapton tape (but just about any thin insulating tape will work)- http://www.sparkfun.com/products/10687
Red Scotchbrite pad
Lily Pad green LED- http://www.sparkfun.com/products/10046
CR1220 watch battery- available at jewelry stores or online
K&S 3/8" OD x .016" wall aluminum tube- http://www.hobbylinc.com/htm/k+s/k+s9409.htm
Transparent green #2092 Acrylic sheet 1/8" thick- http://www.delviesplastics.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=DPI&Category_Code=Transparent_Cast_Acrylic_Sheet
5 minute epoxy
Hot glue gun
Needle nose pliers
Small flat bladed screwdriver
Small piece of solid wire (can be copper or lead clipped off a resistor or other similar electrical component)

So Honus I have one of the Toys R US ring in this tutorial (which is fantastic by the way!). However I am in the middle of a GL Cosplay build. If I mailed you the ring could you get it done and back to me by March 20?
<p>Could you actually make a tutorial on how to carve from plastic sheet or rod? Wax and resin definitely isn't very practical for most people and the tutorial doesn't really elaborate on sheet/rod crafting.</p>
Hello I am a huge Dc fan as I've read below from about a year ago you where not moding rings due to heavy workload. I completely understand but hope you might have the opportunity to do one. I can by the ring separate. And send it to you. However I do understand the amount of tasks and difficulty you must take on with your own projects if you are not able to. thank you
Unfortunately I just can't take on any more work right now- hope you understand!
<p>nice .though I prefer to make one out of cardboard</p>
<p>... Well, at least you can make design by yourself and make a ring prompt by you.</p>
Tel me how you made that
Have you read the instructable?
This looks remarking similar to the following ring. <br>http://www.amazon.com/Green-Lantern-Movie-Exclusive-Keychain/dp/B0052WWSJM/ref=pd_sbs_a_3 <br> <br>Ring looks truly awesome, well done.
That ring looks the same because it is the same ring. :) The instructable is about how to modify that ring and make it light up.
Honus, this is awesome!!! I have a ring!!! Can you please mod it for me? How much will it be?
Sorry but I'm not modding rings for anyone- the mold I made for the inserts finally self destructed and I'm already backlogged with too many other projects!<br>
can I buy one plz!!!!!!!!!!!!!!!! I can afford anywhere from $20.00-$30.00 <br>You can message me for where to send it if u have time. Plz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks so much! I am a huge green lanern fan. I really dont have the resources to complete the tutorial. Is it posibile that I can send you my ring.
Sorry but I'm not taking on any additional work right now- I have a huge backlog of work to catch up on!
Thank you anyway. I will try to complete it on my own. Again I want to thank you for make this tutorial.
Brilliant! Great 'ible!!!
And how much are you selling them for...Just say'n..
I'm not selling the rings. The LED inserts are available from Batjeepster- there's a link on the insert page (Step 3.)
Oh, I figured as such. It was really just a way of complementing the ring. They are very cool and just a bit beyond my capabilities. You could sell them, I bet. (And I'd buy one for my son....and one for me.)
I'm glad you like it! The reason I said I'm not selling them is that I don't have the rings on hand- they are getting hard to find too. If you can get a ring I'll be happy to mod it for you- just message me. <br> <br>My oldest son wants one too. :)
That's an incredibly sweet offer. Thank you. I might just have to take you up on it! I'll let you know.<br><br>Best.<br>Gary
After you cut and sanded the center gem how did you polish it?
I used a tripoli polishing compound and a small polishing wheel. Most any plastic polishing compound should work.
Ok. Thanks.
Love the ring!
That looks so awesome, Honus! BTW, you're my soul subscribee! :D Nice to see another great 'ible!
Thanks so much! I've got some really good stuff in the works too... :)
I'm looking forward to it! :D
