Create 3D printable models that can help students from kindergarten through grad school learn math, physics, botany, chemistry, engineering and more.
This book shows parents and teachers how to use the models inside as starting points for 3D printable explorations. Students can start with these models and vary them for their own explorations. Unlike other sets of models that can just be scaled, these models have the science built-in to allow for more insight into the fundamental concepts. Each of the eight topics is designed to be customized by you to create a wide range of projects suitable for science fairs, extra credit, or classroom demonstrations. Science fair project suggestions and extensive "where to learn more" resources are included, too. You will add another dimension to your textbook understanding of science. The second edition of 3D Printed Science Projects is a thorough update of the original, modernizing the 3D printing technology. 3D Printed Science Projects shows you how to create 3D printable models that can help students from kindergarten through grad school learn math, physics, botany, chemistry, engineering and more. Each of the models is created in the free, open source CAD program OpenSCAD, so it can be customized by the reader. 3D Printed Science Projects particularly targets the technology-squeamish teacher or parent who want their kids tolearn something from their 3D printer but need help getting started. Kids who love science, homeschoolers (and the grandmas who buy them birthday presents) will be customers.

This book will teach you Python programming and some basic electronics without assuming any prior knowledge of either subject. The book initially focusses on Python programming, building up a Morse Code example. The book is suitable for most ESP32 boards, but concentrates on the most popular ESP32 Lite and the ESP32 DevKit 1. In the chapters on electronics, breadboard layouts are provided for both of these boards. ESP32 is a family of processors developed by Espressif Systems (that’s where ESP comes from in the name) that, notably, includes WiFi and Bluetooth capabilities. The processor chip itself is used on many different development boards. Sometimes the processor is placed on the board directly but, at other times, a module is placed on the board. This module, that encloses the processor and a chip, is covered by a metal cap; its design complies with international standards - CE marked for the EU and FCC for the United States. Learning to program, like any skill, requires practice and simple straight-forward examples that you can work through. In this book, you will be led step-by-step through example programs, intermingled with explanations and background.

This book explores different facets of millimeter wave systems, which form a central part of 5G systems. It explains how these systems serve as a foundational building block of 5G-Advanced/6G as these systems evolve. Millimeter Wave Communications in 5G and Towards 6G focuses on millimeter wave channel modeling, radio frequency (RF) and antenna level constraints imposed on beamforming, beamforming design for link level incorporating the RF/antenna constraints and the channel structure, as well as system level deployment considerations. With significant academic and industrial experience, the authors are well-equipped in explaining how the millimeter wave research developed, the fundamental principles/math beneath the technology, and in explaining precisely the “Why?” behind the “What?” that make the 5G-NR specifications. The authors examine point-to-point systems at a single link level and show how the traditional sub-6 GHz-based beamforming procedures simplify to a simplistic signal processing approach of directional beam scanning. This book examines the foundational background that led to specific choices in the millimeter wave part of the 5G-NR spec as well as chart out the roadmap in terms of future research and development activities in this arena. The book ends by providing a scope of future research in this area. This book is geared towards both introductory as well as advanced researchers in both industry and academia working in the areas of 5G, 5G-Advanced and 6G communications. It would also be useful for senior undergraduate and graduate students in universities focusing on wireless communications topics.

The Raspberry Pi makes an ideal match for the Internet of Things. But to put it to good use in IoT you need two areas of expertise, electronics and programming and because of the way hardware and software engineering tend to occupy separate niches, you may need help with combining the two which is what this book sets out to do. The Raspberry Pi family is an attractive set of devices to use to learn about physical computing or the IoT, but what language to use? You can do some IoT development in Scratch and C is powerful, but there is nothing much easier than Python – especially if you already know Python. Add to this the fact that there is a library, GPIO Zero, which makes working with GPIO lines and more sophisticated devices easy, and you can see that it is an even better choice. What is new is that with the Pi 5 none of the existing libraries in other languages work as it is not compatible with previous Pis. This makes GPIO Zero the only easy way to write IoT programs that work on all versions of the Pi including the Pi 5. It is the recommended way to work with the Pi 5 and hence even more attractive to use with all Pis. The only downside of using Python is that it can be too slow for some IoT applications and in this case you really do need C. However, Python is plenty fast enough for projects that involve actions on the tens of millisecond scale and, given how easy it is to perform sophisticated data processing in these situations, it often has the edge.
