Youtuber Spark IO has taken a toy Sting sword and combined it with a Spark Core to transform it into a tool that glows when there are unsecured wi-fi networks nearby.

To celebrate the launch of the new Hobbit flick, we made a version of Sting that turns blue near unsecured Wi-Fi networks. And when you slash the sword, Sting will jump on the network, and publish a message: “{YOUR WI-FI NETWORK} has been vanquished!”

If you want to create your own, here’s a simple tutorial to help you do just that.
