The same quality and durability that allows Lego bricks to be passed down from one generation to the next also allows the brightly colored construction toy to be armed in the worst way imaginable: inside a foot-tracking cannon that he deliberately sends the pieces sliding underfoot like someone. walk
Adam Beedle is apparently a glutton for punishment when it comes to children’s toys. After building an automated turret for a Nerf blaster that sends foam darts into the face (specifically, his face), Beedle has built another weapon of mass annoyance. This time, it’s a camera-equipped, custom-designed blaster that greatly increases the risk of its target stepping on one of the most painful objects known to mankind: the Lego brick.
If you’re not cringing at the thought, take a moment to watch Beedle’s very unscientific experiment to find the most painful Lego brick to step on (don’t worry, he’s not recruiting any unsuspecting friends or family to put up with- it). torture). While it was a simple single-stud brick that caused the most pain, Beedle designed and 3D-printed his spring-loaded launch mechanism to fire standard two-by-eight bricks, which are still no picnic to accidentally discover underfoot.
A basic PC-connected webcam attached to the launcher and powered by the OpenCV computer vision library specifically targets the human foot, although given the camera’s limited image quality, the addition of red socks greatly increases the accuracy of the cannon. When a foot is pointed, the cannon sends the plastic bricks sliding across the floor towards him, creating a minefield of spiked studs and sharp plastic edges.
If you have roommates who are known to sneak into the kitchen and steal your food, a trick like this will ensure you won’t have roommates for long.
