    Lego Printer Prints Lego

    [Gosse Adema] made his very first instructable by detailing his Lego 3D printer build. It’s Prusa i3 based, and originally started out as an A4 plotter with repurposed steppers out of an old HP printer. After upgrading to some NEMA 17 steppers, it became a full-blown 3D printer.

    It turns out that NEMA 17 stepper mounting holes align perfectly with Lego, making it super easy to mount them.

    Printing Chocolate with a LEGO 3D Printer

    Some people think the future will include a 3D printer in every home. We think if LEGO started producing these as kits we’d get pretty close. Introducing the home-made LEGO 3D printer… with a chocolate extruder.

    Mindstorms Soccer Robot Inspired by Real Soccer Robot

    [Bram], a 17-year-old robot fan from the Nertherlands, had an opportunity to watch a RoboCup soccer match played by autonomous robots, and was inspired to create his own Mindstorms version of the robot for a school project.

    The robot he created is around 80 cm in diameter and is controlled by four daisy-chained EV bricks. There are nine large motors for controlling the wheels, two more large motors for grabbing the ball, and two medium motors for the ball-shooting mechanism. It uses a Pixycam for ball detection, and it can identify and move toward the ball so long as it’s within 2.5 m. A gyro sensor determines the robot’s rotational direction.
