Lego from the Sixties and Seventies
NextBrick.net has a post about some really cool LEGO’s from the 60’s and 70’s from Mario, he writes “Dedicated to those of you LEGOmaniacs who are too young to remember the first years of Lego, or who have never had the opportunity to see some of these relics. During my childhood I spent tons of hours playing with Lego, and a large part of my small week’s pay buying spare parts. It would have been strange not to receive at least one Lego set at or birthday. My sister Elena and my brother Stefano are just one and two years younger than I am. They were very fond of Lego too and we usually played together to build very large cities. Not all of our Lego survived, but we still own a very large bunch of pieces, which I am pleased to share with you in this page.” Link.
The Goldfish Online has some really interesting LEGO logic gates – “…designed working NOT, OR, NOR, AND, and NAND gates. Using two NAND gates I have produced a NAND gate latch or Flip-FLop. The natural follow on from these is clocked logic, full-adders and ultimately a genuine “computer” device. At the moment all these gates essentially just demonstrators. They work, but because of the limitations that arise through gear slippage, the real practicable use is probably not that great.” The details of logic gates can be found here – 
Joel writes in with an awesome new LEGO blog…“Nextbrick, a just-started blog about construction toys with a heavy emphasis on Lego. There are just a handful of posts up at the moment, but enough that you should be able to get an idea of what we’re aiming for–short, fun blips from the world of Lego, two or three times a day.” 
Derek writes “The gumbrix came about because so many of my robot projects required the kind of rapid prototyping that Lego really excels at, yet required more in the way of control electronics than Lego was capable of. With a maximum of 3 motors and 3 sensors, the Mindstorms kit was not really capable of the more complicated control strategies that I was interested in.” [
Amazing video of an RCX robot using vision command (or a derrivative) to play pong on a real screen. Jmarco writes: “I have designed a Mindstorm Robot who plays Pong game. It have a Webcam, and it’s controled through Infrared with the laptop computer. There is not trick. It truely plays itself!” [
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 
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.”
