Extreme NXT, Taking your NXT to the next level: LEGO Mindstorms NXT is an outstanding new product that allows anyone to build complex inventions, but there are limits to what you can do with what comes inside the box. This book shows you how to think outside the box and extend the NXT to the next level. With more than twenty-five exciting projects that range from a simple light switch to a cool magic wand that writes words in thin air. The projects are explained with easy step-by-step instructions, and whether you are a novice or an expert you will be able to successfully construct them. A tutorial on breadboard construction and soldering is also included.
New sensors like color, pressure, magnetism, and even the wind are covered along with games like surfing, Pong, and Simon. On the serious side, there are classic engineering challenges like controlling an inverted pendulum, making a robot that follows a wall, and building a light seeking vehicle. Some projects are fun like the fusion of the NXT and an Etch-A-Sketch called the Etch-A-NXT. Other projects are useful like a motorized camera mount that takes 360 degree photographs, or a NXT version of the classic Clapper remote control. Details are presented for practically unlimited expansion of the NXT inputs and outputs by using the I2C communications bus, and several power amplifier designs allow the NXT outputs to drive bigger motors.
So, if you are looking for the next thing to do with your NXT, this is the book for you. If you are involved in robotics, engineering, science, electronics, or just having fun, there is an interesting project in here for you.
