Dragon Doors Round Off Hobbit Themed Restaurant

October 22, 2015 by 20 Comments

[Abhimanyu Kumar] is renovating a hotel in Nainital, near the India-Nepal border, and like any self-respecting Lord of the Rings fan, he wanted to give the restaurant a Hobbit theme. He built circular windows and to top it off a gorgeous round door complete with dragon hinges.

I asked him how well the doors work, as the 50kg (over 110lbs) weight of each of the doors must put a lot of strain on the hinges. [Abhimanyu] told me, “The door opens quite smoothly.While building the hinges even I was concerned about needing support as all other commercially available hinges we tried broke down or got bent.”

However, once the dragon hinge was installed it worked better that we expected and the door stays about 0.5″ over the ground at all times. The dragon hinges (made from 1/4-inch iron) integrate the hinge pins to the wings of the dragon, making it look like they are taking off when the doors open.

He has posted plenty of pictures of the build and the final product looks incredible.  The tail of the dragon is quite long and provides a lot of support for the entire door. Each hinge itself weighs about 30kg, so it should be strong enough to hold up a door for a long time without any sagging. Kudos to him for some serious engineering!

Hobbit Sword Glows Blue, Vanquishes Unprotected Wifi

December 18, 2014 by 10 Comments

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.
