New LEGO MINDSTORMS!
GoRobotics writes “LEGO is finally rehauling it’s Mindstorms kit. At the Las Vegas Consumer Electronics Show (CES) in early January, LEGO Group announced LEGO MINDSTORMS NXT, a new system that redefines the consumer robotics category which the company created in 1998. Robot Magazine has pictures and video. Press release here. My summary is here.“ Link to Robot magazine. Best feature? Download programs via Bluetooth! UPDATE: Wired has a preview of their cover story for next month about this [via] here.
Greg writes “Here is a line following robot that will follow a line, and at the end will stop for three seconds. After pausing for three seconds it will retrace its steps and drive in reverse. It is made with a sensing circuit, and H-bridge motorcontroller, and a microcontroller.” 
Dave is hacking up the new Furby “Yesterday I went and bought the New Furby which just came out in October this year. The new Furby is a pretty darn advanced toy for only $30, if you haven’t seen one before they are basically armless Mogwais with beaks. New Furbys are powered by the Sensory Inc’s RSC-4128 which is a multi-purpose microprocessor that does everything from voice recognition to text-to-speach to IO to DTMF output. After reading through the white paper for the RSC-4128 I was pretty sure that the Furby would be quite the hackable robot, so I decided to take a look inside and see what hacking would entail.” [
“This application note describes a circuit designed to control the speed of a dc motor used in radio-controlled boats. The electronic speed controller (ESC) is a “no-brake, forward-only” controller. I wanted to keep the part count low and the circuit simple so a couple features were sacrificed. The circuit does not have: over-current protection, over-temp protection, polarity protection, or over/under voltage protection. All the parts can be obtained from digikey distributors. The circuit was designed with a popular 12-cell model boat motor in mind (graupner speed 700). This project was my first attempt at using Bascom-avr and Atmel microcontrollers. ” Thanks JasonR! 
Want to study sharks? Build your own Tintin-esque sub – “The grandson of famous oceanographer and filmmaker Jacques Cousteau believes the best way to learn about sharks is to become one. Fabien Cousteau, inspired as a child by the comic book Red Rackham’s Treasure, where the main character, Tintin, adventures underwater in a shark-shaped submarine, decided as an adult to build his own.” Thanks Saul!
