The story of the engineers who shaped the world's most powerful chip machines How do you transform a hopeless research and business activity into a billion-dollar machine and a world-leading company? The Dutch enterprise ASML pulled it off, and the book ASML’s Architects by renowned technology writer René Raaijmakers reveals exactly how. ASML's Architects travels back to the origins, struggles, success factors and sheer luck of a company that was barely alive at the beginning of the 80s, yet managed to become the uncontested world leader in chip lithography. Today, ASML determines the pace at which all information technology advances. The book covers the technology and the business, but the real story is in the people behind them. Throughout its pages, the interviewed engineers, scientists and managers speak frankly about their struggles, their fights and the grueling teamwork behind the scenes.

Quite unintentionally a one-page story on an old Heathkit tube tester in the December 2004 edition of Elektor magazine spawned dozens of ‘Retronics’ tales appearing with a monthly cadence, and attracting a steady flow of reader feedback and contributions to the series. Since launching his Retronics columns, Elektor Editor Jan Buiting has never been short of copy to print, or vintage equipment to marvel at. This book is a compilation of about 80 Retronics installments published between 2004 and 2012. The stories cover vintage test equipment, prehistoric computers, long forgotten components, and Elektor blockbuster projects, all aiming to make engineers smile, sit up, object, drool, or experience a whiff of nostalgia. To reflect that our memories are constantly playing tricks on us, and honoring that “one man’s rubbish is another man’s gem”, the tales in the book purposely have no chronological order, and no bias in favor of transistor or tube, microprocessor or discrete part, audio or RF, DIY or professional, dry or narrative style. Although vastly diff erent in subject matter, all tales in the book are told with personal gusto because Retronics is about sentiment in electronics engineering, construction and repair, be it to reminisce about a 1960s Tektronix scope with a cleaning lady as a feature, or a 1928 PanSanitor box for dubious medical use. Owners of this book are advised to not exceed one Retronics tale per working day, preferably consumed in the evening hours under lamp light, in a comfortable chair, with a piece of vintage electronic equipment close and powered up.

This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview. Even now tube amplifiers still sound great perhaps better than ever before. In part that is because we now have access to modern components such as toroidal output transformers, extremely high-quality resistors and capacitors, and many sorts of wire with good acoustic properties. Modern audio sources, such as CD players, and the latest top-end loudspeakers also enable us to appreciate how well tube amplifiers reproduce music even better than before. This new book from Menno van der Veen looks at tube amplifiers from more than just a theoretical perspective. It focuses primarily on the design phase, where decisions must be taken with regard to the purpose and requirements of the amplifier, and it addresses the following questions: How do these aspects relate to subjective and objective criteria? Which circuits sound the best, and why? If you want to develop and market an amplifier, what problems should you expect? What are the significance and meaning of measurements? Are they still meaningful, or have they lost their relevance? Thanks to the enormous processing power of computers, we can now measure more details than ever before. How can these new methods be applied to tube amplifiers? Previously it was sufficient to measure the frequency range, power and distortion of an amplifier in order to characterize the amplifier. Are these measurements still sufficient, or should we start measuring according to how we hear, using real music signals instead of waveforms from signal generators? The author sketches a future where amplifier measurements that conform to our sense of hearing enable us to arrive at new insights. This book focuses more on practical aspects than on theory, and it has an contemplative nature, as though the author were viewing amplifiers from above. Knowledge elements are integrated and placed in the context of a broad overview.

Program, build, and master 60+ projects with the Wireless RP2040 The Raspberry Pi Pico and Pico W are based on the fast, efficient, and low-cost dual-core ARM Cortex M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM and 2 MB of Flash memory. Besides spacious memory, the Pico and Pico W offer many GPIO pins, and popular peripheral interface modules like ADC, SPI, I²C, UART, PWM, timing modules, a hardware debug interface, and an internal temperature sensor. The Raspberry Pi Pico W additionally includes an on-board Infineon CYW43439 Bluetooth and Wi-Fi chipset. At the time of writing this book, the Bluetooth firmware was not yet available. Wi-Fi is however fully supported at 2.4 GHz using the 802.11b/g/n protocols. This book is an introduction to using the Raspberry Pi Pico W in conjunction with the MicroPython programming language. The Thonny development environment (IDE) is used in all of the 60+ working and tested projects covering the following topics: Installing the MicroPython on Raspberry Pi Pico using a Raspberry Pi or a PC Timer interrupts and external interrupts Analogue-to-digital converter (ADC) projects Using the internal temperature sensor and external sensor chips Using the internal temperature sensor and external temperature sensor chips Datalogging projects PWM, UART, I²C, and SPI projects Using Bluetooth, WiFi, and apps to communicate with smartphones Digital-to-analogue converter (DAC) projects All projects are tried & tested. They can be implemented on both the Raspberry Pi Pico and Raspberry Pi Pico W, although the Wi-Fi-based subjects will run on the Pico W only. Basic programming and electronics experience are required to follow the projects. Brief descriptions, block diagrams, detailed circuit diagrams, and full MicroPython program listings are given for all projects.
