Affordable solutions with the ESP8266 and 3D printing If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop. Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring. You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book. All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.

All you need to know about good acoustics and sound systems in performance and worship spaces! Everyone knows that the ability to hear music in balance and to understand speech is essential in any space used for performance or worship. Unfortunately, in the early 21st century, we find that buildings with good acoustics are the exception rather than the rule. Much of the fault leading to this result can be traced to the widespread perception that acoustics is a black art. In fact, scientific acoustics as developed in the last century is a well-defined engineering practice that can lead to predictable excellent results. A basic, non-engineering understanding of acoustics will help building owners, theater managers, ministers and teachers of music, performers, and other professionals to achieve their goals of excellent acoustics in venues with which they work. Performers having a basic understanding of acoustics will be able to make the most of the acoustics of the venue in which they perform. This book helps those responsible for providing good acoustics in performance and worship spaces to understand the variables and choices entailed in proper acoustic design for performance and worship. Practicing acoustical consultants will find the book a useful reference as well. The level of presentation is comfortable and straightforward without being simplistic. If correct acoustical principles are incorporated into the design, renovation, and maintenance of performance and worship venues, good acoustics will be the result.

A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

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.

Resonances From Aether Days A Pictorial and Technical Analysis from WWII to the Internet Age From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day. All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history. My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.
