Gesture Controlled Sword of Omens Gives Sight Beyond Sight

The 80’s were a golden age of Sci-Fi cartoons. We had Transformers, Voltron, and of course, Thundercats. The story of feline humanoids on third earth has stuck with a few hackers, including [Juan Garcia]. Juan has tunneled his fandom into something amazing – he’s built his own version of Lion-O’s iconic Sword of omens. The modeling and 3D print work are top-notch. While this sword doesn’t have the Eye of Thundera as a power source, it does have some pretty clever electronics. It’s also one of the amazing entries in this year’s Sci-Fi Contest.

[Juan] wanted to create the “sight beyond sight” effect from the TV show. He started with an MPU6050 six axis gyro + accelerometer. These chips are most often found at the heart of quadcopter controllers. An Arduino Pro Mini reads the sensor data. When the sword is lifted vertically, it turns on a row of WS2812 LEDs. The LEDs replicate the pulsing eye effect from the cartoon version of the sword.

[Juan] really made this a neat build. The whole sword is powered by an 18650 Li-Ion battery. Power control and charging circuitry are all concealed inside the 3D print. When it’s time to charge up the eye, the hilt can be unscrewed to reveal a USB charging port. Click past the break to see this hack in action!

Thundercats, HO!

[Tony Swatton], blacksmith, armorer, and prop maker, has built hundreds of custom swords for hundreds of movies and TV shows. He’s also the maker behind Man at Arms, the YouTube series where weapons from your favorite shows and movies are recreated, be they improbable weapons from a James Bond movie or a sword from a cartoon. This time, he recreated the Sword of Omens from Thundercats. It’s a work of art in its own right, and amazingly practical for a cartoon sword.

The Sword of Omens is one of [Tony]’s more complex sword making endeavors he’s done. The grip is made of seven different pieces cast in bronze, while the hilt of the sword is over a dozen of different pieces of steel welded together. The jewel in the sword was cut from a piece of glass, carefully ground on a lapidary wheel to a perfect dome.

Of course, this isn’t the only weapon from popular media that [Tony] has crafted. He’s also done Oddjob’s hat from James Bond and Finn’s golden sword of battle from Adventure Time.
