Submission + - Geek wedding ring? 13

RoadNotTaken writes: Dear Slashdot,
I finally bit the bullet and decided to get married. My fiance and I are looking for wedding rings and I find myself disappointed that they have so-few features. Are there any geeky rings out there that can do something useful? I'm thinking USB or RFID but am open to suggestions. There has to be SOMETHING good you can do with a chunk of metal on your finger...

    Seems the easiest answer is a link: http://www.thinkgeek.com/blog/2008/10/my-big-ntfs-geek-wedding.html [thinkgeek.com] - they seem to have a pretty decent selection there, including a link to a previous Slashdot topic: http://ask.slashdot.org/article.pl?sid=08/08/30/022237 [slashdot.org]

    On a more personal level, I know people who've spent a few months learning to smelt their own and gone down that route. Or the old favorite, The One Ring!

    Hi, you can use RFID tags to open your front door by adding some extra kit to the door. It's not very expensive and her ring could do it as well. I'd guess the drawback could if someone figured it out and stole the ring.

    A tungsten carbide [titaniumkay.com] ring. With a hardness of over 9 mohs (diamond is 10), and a melting temperature of over 6000F, it is much more 'forever' than a diamond (which burns in air at 1600F, turning into carbon dioxide and blowing away). And while we can make diamonds in a lab, tungsten still has to be mined out of the earth.

      From the wikipedia article you quoted:

      The use of DU in munitions is controversial because of questions about potential long-term health effects.

      Depleted Uranium is not at all dangerous from a radioactive sense but the long term chemical toxicity is not really understood. Turning your wedding ring into a 2-subject study of the long term effects of Uranium exposure might not be the best choice. I'd stick with the tungsten carbide.

  • Thanks for the suggestions, but those all appear to be rings that LOOK geeky. Are there no rings that actually serve a purpose? If I'm going to wear a little gadget on my finger for 20+ years it would be nice if it actually did something. I'm thinking data storage, magnetism, lasers, etc. Anything?
    • Any ring worn on the left ring finger will tend to make it harder to date.

      Isn't that enough?

      The ring really shouldn't need to be multifunctional. It is symbolic adornment, meant to convey a message. If that isn't enough, don't get married.

      Any technological enhancements embedded within such a ring will likely be deprecated within ten years, anyway. Do you really want to run upgrades on the thing?

      Talk with a jeweler who does custom work, as they know their materials and methods. Have a more detailed description of your personal preferences, so they can suggest appropriate patterns such as leaves, mice, rats, dolphins, Chevy pickups, Mac I, Difference Engine, Cookie Monster, etc.

      You could have a jeweler mount an RFID tag (size of grain of rice), or a magnetic sphere on, or in, a ring. I don't know what metals are RF transparent so the RFID antenna would work. Go shopping for the kinds of RF tags y

    Just buy an expensive one and when - if - she/he dies - use the automatic coffee-cup holder in your PC to slice off the finger and recover your investment.
  • www.greenkarat.com has a ring set up to be engraved with your message in binary. I think I remember seeing some other geekish stuff there when I was browsing. And their stuff is eco-friendly!
