2008: JohnNXT is my LEGO MINDSTORMS NXT replica of Johnny 5, the robot star of the Short Circuit movies. Its building and programming instructions are included in my first LEGO MINDSTORMS NXT book. JohnNXT is an evolution of my first LEGO MINDSTORMS RCX Johnny 5.

Even if you are too young to know Johnny 5, you will surely like my LEGO WALL-E!
