The Hacksmith: Spinning Helicopter Mount for Thanos' Sword

Avengers: Endgame broke all kinds of records at the box office this summer. It was the culmination of the Marvel Cinematic Universe’s “Phase 3” and contains one of the most epic battles ever made into film. While we won’t spoil the movie for those who haven’t seen it, we will say this: Thanos has a really cool double-sided sword that is strong enough to crack even Captain America’s shield.

Hacksmith Industries recreated Thanos’ sword in a previous video, but ran into a problem while testing it against Captain America’s shield. It turns out that we puny mortals lack the arm strength to properly wield the Mad Titan’s blade properly. In order to generate enough momentum to spin the blade around like Thanos, Hacksmith had to create a remote-controlled mount that requires a lot of power. Like 16,000 Watts worth of it. This creation was dubbed the “Thanos Copter.” Check it out in the video below!


How Does it Work?

The blade’s handle is attached to a sprocket in the center, which is attached to a chain that is propelled by a motor. This spins the sword around like a helicopter, or like Thanos himself.

The speed of the blade’s rotation is controlled by a remote, which acts as a throttle and gives input to an Arduino Nano and sends it to the 16,000 Watt motor. With such a powerful motor, the “Thanos Copter” had to be powered by a forklift’s battery because puny wall outlets were no match for the Mad Titan.

A Hall Effect sensor is used to gauge the Thanos Copter’s RPM. The Hall Effect sensor counts how many times the magnets inside the motor rotate. With some extra math, how much energy going into the Thanos Copter can be measured as well!
