A Hands-on Guide to Crafting Your Own Power Plant The book you are about to read provides a step-by-step guide for building a renewable energy power plant at home. Our goal was to make the book as practical as possible. The material is intended for immediate application with a small amount of theory. Yet, the theory is important as a foundation that saves time and effort by disabusing the readers of potential misconceptions. Specifically, upon having a firm understanding of photovoltaic physics, you will not be inclined to fruitlessly search for 90% efficient solar panels! We want our readers to be the “doers”. If the book gets covered in grime and some pages become torn while you are building your power plant – this is the best compliment to us. The book covers solar and wind energy. Also, a curious power source based on manure is discussed as well, giving the doers an opportunity to further develop the manure fuel cell. It is important to note that there are many companies offering installation of complete solar solutions. Upon installing the panels, the system is not owned by the customer. Therefore, there is no freedom for experimentation and optimization. Also, none can beat the cost of a DIY solution as well as the ultimate satisfaction. All that is written here is a result of us building a renewable energy solution in Southern California. As the book was completed, the energy began flowing!

The intention of this book is to offer the reader understandings, ideas and solutions from the perspective of a workbench technician and electronics hobbyist. It is a descriptive text with many tables of useful data, servicing tips and supplementary notes of not so common knowledge. Today there is a re-emerging, nostalgic interest in vinyl records and associated music entertainment gear. With this interest, there is a paralleled market for the repair of this gear. This ‘hands-on’ servicing guide opens with fundamental considerations of the work space of repair and servicing. This includes a comprehensive discussion of essential test equipment and tools. Two chapters are devoted to obtaining servicing information about repair and obtaining spare parts. A key chapter is on general diagnosis and testing and includes the discussion of resistance, capacitance and inductance. These electrical properties are regularly in the mind of the repairer, so understanding of them is a key objective of this book. The next chapter is about time saving repair techniques and ensuring quality repair. The remaining chapters discuss entertainment equipment itself. Each of the chapters begins with an orderly discussion of the theory of operation and common and not so common problems specific to the equipment. All chapters conclude with a summary.

The Internet of Things (IoT) is a new concept in intelligent automation and intelligent monitoring using the Internet as the communications medium. The “Things” in IoT usually refer to devices that have unique identifiers and are connected to the Internet to exchange information with each other. Such devices usually have sensors and/or actuators that can be used to collect data about their environments and to monitor and control their environments. The collected data can be processed locally or it can be sent to centralized servers or to the cloud for remote storage and processing. For example, a small device at the size of a matchbox can be used to collect data about the temperature, relative humidity and the atmospheric pressure. This data can be sent and stored in the cloud. Anyone with a mobile device can then access and monitor this data at any time and from anywhere on Earth provided there is Internet connectivity. In addition, users can for example, adjust the central heating remotely using their mobile devices and accessing the cloud. This book is written for students, for practising engineers and for hobbyists who want to learn more about the building blocks of an IoT system and also learn how to setup an IoT system using these blocks. Chapter 1 is an introduction to the IoT systems. In Chapter 2, the basic concepts and possible IoT architectures are discussed. The important parts of any IoT system are the sensors and actuators and they are described briefly in Chapter 3. The devices in an IoT system usually communicate with each other and the important aspect of IoT communication is covered in Chapter 4. Chapter 5 proceeds with the features of some of the commonly used development kits. One of these, the Clicker 2 for PIC18FJ manufactured by mikroElektronika, can be used as a processor in IoT systems and its features are described in detail in Chapter 6. A popular microcontroller C language, mikroC Pro for PIC gets introduced in Chapter 7. Chapter 8 covers the use of a click board with the Clicker 2 for PIC18FJ development kit. Similarly, the use of a sensor click board is described as a project in Chapter 9, and an actuator board in Chapter 10. Chapters 11 and 12 cover Bluetooth and Wi-Fi technologies in microcontroller based systems, and the remaining chapters of the book demo the creation of a simple Wi-Fi based IoT system with cloud-based data storage. This book has been written with the assumption that the reader has taken a course on digital logic design and has been exposed to writing programs using at least one high-level programming language. Knowledge of the C programming language will be very useful. Also, familiarity with at least one member of the PIC series of microcontrollers (e.g. PIC16 or PIC18) will be an advantage. The knowledge of assembly language programming is not required because all the projects in the book are based on using the C language. If you are a total beginner in programming you can still access the e-book, but first you are advised to study introductory books on microcontrollers.

Develop innovative hardware-based projects in C The Raspberry Pi has traditionally been programmed using Python. Although this is a very powerful language, many programmers may not be familiar with it. C on the other hand is perhaps the most commonly used programming language and all embedded microcontrollers can be programmed using it. The C language is taught in most technical colleges and universities and almost all engineering students are familiar with using it with their projects. This book is about using the Raspberry Pi with C to develop a range of hardware-based projects. Two of the most popular C libraries, wiringPi and pigpio are used. The book starts with an introduction to C and most students and newcomers will find this chapter invaluable. Many projects are provided in the book, including using Wi-Fi and Bluetooth to establish communication with smartphones. Many sensor and hardware-based projects are included. Both wiringPi and pigpio libraries are used in all projects. Complete program listings are given with full explanations. All projects have been fully tested and work. The following hardware-based projects are provided in the book: Using sensors Using LCDs I²C and SPI buses Serial communication Multitasking External and timer interrupts Using Wi-Fi Webservers Communicating with smartphones Using Bluetooth Sending data to the cloud Program listings of all Raspberry Pi projects developed in this book are available on the Elektor website. Readers can download and use these programs in their projects. Alternatively, they can customize them to suit their applications.

The Arduino Uno is an open-source microcontroller development system encompassing hardware, an Integrated Development Environment (IDE), and a vast number of libraries. It is supported by an enormous community of programmers, electronic engineers, enthusiasts, and academics. The libraries in particular really smooth Arduino programming and reduce programming time. What’s more, the libraries greatly facilitate testing your programs since most come fully tested and working. The Raspberry Pi 4 can be used in many applications such as audio and video media devices. It also works in industrial controllers, robotics, games, and in many domestic and commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which makes it great for remote and Internet-based control and monitoring applications. This book is about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control applications. The book starts with basic theory of the control systems and feedback control. Working and tested projects are given for controlling real-life systems using PID controllers. The open-loop step time response, tuning the PID parameters, and the closed-loop time response of the developed systems are discussed together with the block diagrams, circuit diagrams, PID controller algorithms, and the full program listings for both the Raspberry Pi and the Arduino Uno. The projects given in the book aim to teach the theory and applications of PID controllers and can be modified easily as desired for other applications. The projects given for the Raspberry Pi 4 should work with all other models of Raspberry Pi family. The book covers the following topics: Open-loop and closed-loop control systems Analog and digital sensors Transfer functions and continuous-time systems First-order and second-order system time responses Discrete-time digital systems Continuous-time PID controllers Discrete-time PID controllers ON-OFF temperature control with Raspberry Pi and Arduino Uno PID-based temperature control with Raspberry Pi and Arduino Uno PID-based DC motor control with Raspberry Pi and Arduino Uno PID-based water level control with Raspberry Pi and Arduino Uno PID-based LED-LDR brightness control with Raspberry Pi and Arduino Uno
