Whilst the original Sting glowed blue as a defensive alert, Spark’s “WarSting” is all about aggression. The project hacks a toy Hobbit sword and teaches it to glow blue when vulnerable WiFi is detected. Once alerted, combat ensues. If its bearer slashes, the sword will battle the helpless network, swinging and clanging until it acquires an IP from the defeated DHCP server. Once conquered, the sword publishes a “Vanquished” message to Spark’s cloud, teaching the sword to ignore it from thenceforth.
While “wardriving” has not really been a thing since the first Lord of the Rings movie came out, the last time we saw someone do something similar the hardware was limited to detecting WiFi, not connecting.
Spark CEO [Zach] chose the particular sword because it could be disassembled without being cut apart and already came equipped with easily-hackable LEDs, motion control, and sound effects. Naturally he added one of his own products – the Spark Core – to the hilt to graft WiFi features onto the weapon (a cheaper alternative would be an MCU of your choice and the new ESP8266). The project then hijacks the LED lighting, sound, and hit detection sensor. Our readers can probably come up with some more imaginative actions to take once connected, though the project’s existing code for the Core is published on Github. As-is, in many jurisdictions even merely connecting to an unsecured WiFi these days is unlawful so beware your local restrictions.
Lots of companies could simply advertise the easy way and while obviously an ad, the WarSting is still a creative and fun hack.
See the video below for the sword in action and a Spark’s lore regarding the hack. Thanks [Chris] for the tip.

Was done before in early 2013: http://hackaday.com/2013/01/21/plastic-sword-detects-wifi-enabled-orcs/
But it looks nice nevertheless.
Indeed, good eye. Was aware “something similar” was done before, hence why in the article I linked it as “something similar.” :P
Similar, but this one does new things. The old hack only glows blue. As I understand it, the $5 keychain thing does not allow one to connect to any network, just detect it. This one joins the network, plays sounds as it battles, and publishes a little remark after “defeating” the network. Which in itself is kinda meh, bit of publicity for Spark, but it’s open ended enough our readers could be inspired to do lots more with it.
Also, the final Tolkien movie is out, so, it’s timely and topical. As opposed to, oh, a few years from now it probably would not have been on people’s minds enough to warrant a post.
I thoroughly enjoyed the skit at the end.
Nicely done. I’m planning a new version of my “something similar” version, but it shall remain hidden until such a time as it can be reforged..
Well, the blade is of Elfish make so give ’em another couple weeks. I hear they have some scheduled downtime until next year’s production list is finished.
For some reason I thought it was cracking WEP networks.
That would definitely be worth having.
Have you considered making a Ring version, the ‘One’ that calls them all, yet?
Yup. The skit in the end takes the cake.
And I thought all public Wi-Fi are unencrypted? Including those that requires user to sign-in, e.g. hotels’ wi-fi.
I would use it to detect people I want to avoid nearby, e.g. via their Wi-Fi or BT.
I can see a lot of “war driving” ” hobbits” getting tasered.
