Flying Fortress Lego blimp lords over us with a Mindstorms-based iron fist (video)
Most Lego Mindstorms constructions have never slipped the surly bonds of Earth. The Flying Fortress Lego Blimp from Tyler Westmoreland and Chris Shepard won't be similarly held down, however. Courtesy of two NXTBee wireless adapters, Tyler and Chris can fly the Mindstorms NXT-driven airship using a remote control and adjustable propellers. There's no secret tricks involved, as everything is an off-the-shelf part that anyone can find, including the 55-inch helium balloons. We have proof: Tyler has shared the source code for both the blimp and the controller, so anyone with the resources can recreate the Flying Fortress for themselves. While the thought of homemade drone blimps looming overhead is slightly disconcerting, we'll steel our resolve when it means that most any enterprising builder can take Lego airborne.

NXTBee enables long-distance wireless for Mindstorms NXT, funny little RC cars (video)
Lego Mindstorms NXT is robotic democratization, DIY designing for the everyman, but being stuck with only Bluetooth or IR wireless can put a bit of a damper on your egalitarian goals. No more. Dexter industries (who previously brought us solar-powered Mindstorms) has created the NXTBee, which uses the an Xbee radio to send data much further: 300 feet for the base $55 NXTBee, up to a mile if you opt for the $78 NXTBee-PRO. You'll probably need two of the things, though, so make sure you budget appropriately. There's definitely some lag evident in the video of a long-range RC car below, but we're not sure if that's the wireless or the machine itself. Regardless, that's surely a design challenge that won't stop you from having fun with this one.
