In this wickedly entertaining and thoroughly informed homage to one of rock music??s towering pinnacles, Erik Davis investigates the magic??black or otherwise??that surrounds this album. Carefully peeling the layers from each song, Davis reveals their dark and often mystical roots??and leaves the reader to decide whether [FOUR SYMBOLS] is some form of occult induction or just a...(展开全部)

The members of Led Zeppelin are major deities in the pantheon of rock gods. The first and heaviest of the heavy metal monsters, they violently shook the foundations of rock music and took no prisoners on the road. Their tours were legendary, their lives were exalted—and in an era well known for sex and drugs, the mighty Zeppelin set an unattainable standard of excess and mythos...(展开全部)

本以为变成LED灯珠就已是巅峰，没想到还有惊喜？ 突然说我所处的世界其实是个游戏形态的收容物。 要我这个LED灯珠成为万机之神，出去拯救因收容失败濒临毁灭的世界。 ………… 我没听错吧？

An Arduino might be a tiny computer but it can be used as the foundation for a huge range of projects. In this course, we’ll show you how just some of the projects that are possible with an Arduino. From robotics to secret agent gadgets, we’re pretty confident that this course will get you thinking creatively – and inspire you to create your very own new projects using the Arduino hacking skills you learn.This course, combines both text and video content – it’s made up of three modules to help organize your learning. In the first module we’ll show you how to build three different Arduino projects. All of these will not only get you up and running with something practical, they’ll also help you better understand how the Arduino works. Find out how to develop a home automation system and even build a robot!In the second module we’ll go one step further to help you get creative as you learn how to program LEDs with your Arduino. You’ll find out how to build a mood lamp and a remote-controlled TV backlight, before going on to make a sound controlled LED Christmas tree that makes use of sound visualization.Finally, the third module takes you from stylish design into espionage, as you learn how to create neat secret agent gadgets with your Arduino. Find out how to build an alarm system, a fingerprint sensor, even open a lock with a text message. And that’s not all – but to find out more you’ll have to dive in!This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products:Arduino By Example by Adith Jagadish Boloor.Arduino BLINK Blueprints by Samarth Shah, Utsav Shah.Arduino for Secret Agents by Marco Shwartz.
