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.

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.

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.

The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions. After the description of the CPU design is complete the design is expanded to include memory and some simple I/O. The resulting microcontroller will then be implemented in an affordable FPGA development board (available from Elektor) along with a simple software application so that the reader can investigate the finished design.
