This book is all about building your own DIY home control system. It presents two innovative ways to assemble such a system: By recycling old PC hardware – possibly extending the life of an old PC, or by using Raspberry Pi. In both cases, the main system outlined in this book will consist of a computer platform, a wireless mains outlet, a controller and a USB webcam – All linked together by Linux.
By using the Raspberry Pi in conjunction with Arduino (used as an advanced I/O system board), it is possible to construct a small, compact, embedded control system offering enhanced capacity for USB integration, webcams, thermal monitoring and communication with the outside world.
The experience required to undertake the projects within this book are minimal exposure to PC hardware and software, the ability to surf the internet, burn a CD-ROM and assemble a small PCB.

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.

This DIY LiPo Supercharger/Booster (developed the electronics engineer/YouTuber GreatScott! and produced by Elektor) can charge a single-cell LiPo battery and protect it against the effects of overvoltage, overload, and short-circuits. Additionally, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an ‘eFuse’ IC outputting 1.52 A at 5 V or 0.76 A at 12 V maximum.
The charger part of the circuit needs a +5 V power supply which can be connected through USB-C, or simply two wires soldered to pads on the PCB.
In addition, other connections can be soldered to pads on the PCB or by using single pinheaders.
