Watch This Laser Guided Knife Throwing Machine Nail 10 In A Row

It looks like something out of a video game, but this device is real: a portable, mechanical, computerized, laser-guided knife gun that actually shoots spinning knives end to end through the air (via gizmodo).

This isn’t a slingshot or coiled Kunai shooter that launches those blades forward, oh no: Quint Builds set out to build a device that can accurately throw knives like a pro, nailing a target 10 times in a row at varying distances. That meant painstakingly calculating how to spin a knife the right number of times to land point first, over and over and over again, and employing a homemade lidar laser guidance system to measure that distance and adjust the knife’s trajectory accordingly.

Otherwise, a knife might bounce harmlessly off the target…just like mine did so many times at the last Renaissance Faire I attended.

The final contraption dispenses more than 10 knives from a spring-loaded integrated magazine on an electromagnet attached to a carriage, which moves along its track at 10 meters per second thanks to a pair of motorized belts, which in turn are powered by A Pair of 36V hoverboard batteries. Once the carriage reaches the midpoint of its travel, the electromagnet is programmed to release the knife, allowing it to hit a target up to 15 feet away.

I guess you can add “throwing knives” to the list of tasks humans are becoming obsolete at!
