This book discusses the basic components of any alarm system. All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter. With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second. You don’t have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don’t have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author‘s experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself. To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

An 8-in-1 test & measurement instrument for the electronics workbench A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more. The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts.

Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel. This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project. Readers should be able to use the projects as they are, or modify them to suit their own needs. The following Python multitasking modules have been described and used in the projects: Fork Thread Threading Subprocess Multiprocessing The book includes simple multitasking projects such as independently controlling multiple LEDs, to more complex multitasking projects such as on/off temperature control, traffic lights control, 2-digit, and 4-digit 7-segment LED event counter, reaction timer, stepper motor control, keypad based projects, car park controller, and many more.

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!

Create Models for 3D Printing, CNC Milling, Process Communication and Documentation Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication. OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class. OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples. Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!
