Sure, there are plenty of wacky and awesome UAVs out there, but this one, the Blade CX2, or "Wash UAV" is quite charming in all of its wires-hanging-out glory. It's a complex little machine, too. Built using an Arduino Mini, ultrasonic sensors, and a compass module, the vehicle is able to fly autonomously and sense things like walls and the floor. Its flight is short-lived -- just six seconds -- but the video is rife with riveting commentary explaining how various parts of the Blade function, so check it out after the break.
