Robots, Arduino, and monsters are all very close to our new-age, gadget-loving hearts. The folks over at Union Bridge Labs have created a half-monster, half-machine dubbed the Yarn Monster. This little cubic beast has one job -- to eat yarn and shape it into a perfectly rolled ball of, well, yarn. It's powered by a ton of hardware, from a stepper motor to Arduino components to even a universal mounting hub. Instructions to control speed of the nom-noming are sent to the Arduino via XBee from a remotely connected potentiometer which can also reverse the direction of yarn-ball rolling. We encourage you to spend your hard-earned dough (about $130), buy the proper components and build one of these things to impress your loved ones. If not though, be sure to watch the video after the break.
