In its annual competition, the First LEGO League (FLL) is asking participants to design, build, and program a robot that addresses the needs of physically disabled people. The competition, open to kids ages 9-14, lets competitors use LEGO bricks and other parts such as sensors, motors, and gears to build a structure that conforms to the theme of the year. Opportunities are available to organize or coach a team. Registration ends in September. To learn more go to http://rbi.ims.ca/3853-523.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
