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.
32 new Projects, Practical Examples and Exercises with the Elektor Arduino Nano MCCAB Training Board
Electronics and microcontroller technology offer the opportunity to be creative. This practical microcontroller course provides you with the chance to bring your own Arduino projects and experience such moments of success. Ideally, everything works as you imagined when you switch it on for the first time. In practice, however, things rarely work as expected. At that point, you need knowledge to efficiently search for and find the reason for the malfunction.
In this book for advanced users, we delve deep into the world of microcontrollers and the Arduino IDE to learn new procedures and details, enabling you to successfully tackle and solve even more challenging situations.
With this book, the author gives the reader the necessary tools to create projects independently and also to be able to find errors quickly. Instead of just offering ready-made solutions, he explains the background, the hardware used, and any tools required. He sets tasks in which the reader contributes their own creativity and writes the Arduino sketch themselves.
If you don’t have a good idea and get stuck, there is, of course, a suggested solution for every project and every task, along with the corresponding software, which is commented on and explained in detail in the book.
This practical course will teach you more about the inner workings of the Arduino Nano and its microcontroller. You will get to know hardware modules that you can use to realize new and interesting projects. You will familiarize yourself with software methods such as ‘state machines,’ which can often be used to solve problems more easily and clearly.
The numerous practical projects and exercise sketches are once again realized on the Arduino Nano MCCAB Training Board, which you may already be familiar with from the course book ‘Microcontrollers Hands-on Course for Arduino Starters’, and which contains all the hardware peripherals and operating elements we need for the input/output operations of our sketches.
Readers who do not yet own the Arduino Nano MCCAB Training Board can purchase the required hardware separately, or alternatively, build it on a breadboard.

Arduino-compatible, ESP32-controlled, 2-wheeled Balancing Robot
The Elektor Mini-Wheelie is an experimental autonomous self-balancing robot platform. Based on an ESP32-S3 microcontroller, the self-balancing robot is fully programmable using the Arduino environment and open-source libraries. Its wireless capabilities allow it to be controlled remotely over Wi-Fi, Bluetooth or ESP-NOW or to communicate with a user or even another robot.
An ultrasonic transducer is available for detecting obstacles. Its color display can be used for displaying cute facial expressions or, for the more down-to-earth users, cryptic debug messages.
The robot comes as a neat kit of parts that you must assemble yourself. Everything is included, even a screwdriver.
Note: The Mini-Wheelie is an educational development platform intended for learning, experimentation, and robotics development. It is not classified as a toy for children, and its features, documentation, and intended audience reflect this purpose. The product is aimed at students, educators, and developers who wish to explore robotics, programming, and hardware integration in an educational setting.
