World's Simplest Motor Mk2?

World's Simplest Motor


A motor made only by a copper wire and a neodymium magnet. It uses one AAA battery but it can be done with AA one too. It's a simple motor, but unfortunately is not an efficient one, the battery drains quickly and heats up.

Drone Construction Workers

Why not build buildings with drones? These little guys were programmed to build a tower out of styrofoam blocks. If the idea can scale up, it could completely change architecture and construction.

Level Headed

The GLM 80 is the first distance finder that doesn’t require users to hold it perfectly level to get accurate readings. While its laser rangefinder calculates the distance to a target, a tilt sensor measures the angle at which you’re holding the device and adjusts the final measurement accordingly.

Dust Ball

Powered by a compact version of the 4.8-volt battery in Black & Decker’s big hand vacs, this grapefruitsize model is made to sit on your desk or workbench, ready to sweep up crumbs or sawdust. Its handle and nozzle flip out at the press of a button and then fold back into the sphere so it can snap into a charging cradle.
