Never able to find an open Wi-Fi signal when you need one? Maybe you should carry around this sword. Modeled after Frodo’s weapon in The Lord of the Rings, it glows when it’s within range of open Wi-Fi.

The blade is called WarSting, and it’s named after Sting, the mythical Elvish blade from The Hobbit and Lord of the Rings that glows when orcs or goblins are near.

WarSting works similarly, but as created by Spark IO, it doesn’t need orcs to start emitting an otherworldly glow. Instead, it lights up when it senses unsecured Wi-Fi access points nearby.

WarSting isn’t just a novelty though. It can actually hack into an unsecured Wi-Fi access point, publishing a message that says, “[YOUR WI-FI NETWORK] has been vanquished!” when it gains access to an unprotected network.

Want to make your own WarSting? If you’ve got the know-how, you can do it with a Spark Core, a Wi-Fi dev kit, two AA batteries, some LEDs and little else.
