Valve Amplifiers are regarded by many to be the ne plus ultra when it comes to processing audio signals. The combination of classical technology and modern components has resulted in a revival of the valve amplifier. The use of toraidal-core output transformers, developed by the author over the past 15 years, has contributed to this revival. The most remarkable features of these transformers are their extremely wide frequency ranges and their very low levels of linear and nonlinear distortion. This book explains the whys and wherefores of toroidal output transformers at various technical levels, starting with elementary concepts and culminating in complete mathematical descriptions. In all of this, the interactions of the output valves, transformer and loudspeaker form the central theme. Next come the practical aspects. The schematic diagram of a valve amplifier often appears to be very simple at first glance, but anyone who has built a modern valve amplifier knows that a lot of critical details are hidden behind this apparent simplicity. These are discussed extensively, in connection with designs for amplifiers with output powers ranging from 10 to 100 watts. Finally, the author gives some attention to a number of special valve amplifiers, and to the theory and practice of negative feedback. In summary, this book offers innovative solutions for achieving perfect audio quality. Do-it-yourself builders, as well as persons who want to gain a deeper technical understanding of the complex world of audio transformers, valve amplifiers and audio signal processing, will find this book a rich and useful source of information.

As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems. The issue also contains practical information on solar panel installation and the technology behind them.

Spookt het in je huis? Of, beter gezegd, ben je ervan overtuigd dat het spookt in je huis, maar heb je het nooit kunnen bewijzen omdat je nooit een camera hebt gehad die geïntegreerd is met je Raspberry Pi Zero, maar toch klein genoeg is om de spoken niet op te merken?Gelukkig is de spionagecamera voor Raspberry Pi Zero kleiner dan een duimnagel met een resolutie die hoog genoeg is om mensen, geesten, of wat het ook is dat je zoekt, te zien. Hij is ongeveer zo groot als een mobiele telefooncamera - de module is slechts 8,6 x 8,6 mm - met slechts een 2' kabel, zodat je een extra compacte en geniepige kleine spioncamera kunt maken. Hij heeft een openingshoek van 160 graden voor een zeer breed/vervormd fisheye effect dat geweldig is voor beveiligingssystemen of om een groot deel van de woonkamer of de weg te bekijken..Net als het Raspberry Pi cameraboard wordt het op je Raspberry Pi Zero v1.3 of Zero W aangesloten via de kleine aansluiting op de rand van het board dicht bij de 'PWR in' aansluiting. Deze interface maakt gebruik van de speciale CSI interface, die speciaal is ontworpen voor interfacing met camera's. De CSI bus kan extreem hoge datasnelheden aan, en transporteert uitsluitend pixelgegevens.De camera is verbonden met de BCM2835 processor op de RPi via de CSI bus, een verbinding met hogere bandbreedte die pixelgegevens van de camera terugvoert naar de processor. Deze bus loopt via de lintkabel waarmee het cameraboard aan de Pi is bevestigd. De lintkabels zijn compatibel met zowel de RPi Zero v1.3 als de RPi Zero W.De sensor zelf heeft een native resolutie van 5 megapixels en heeft een lens met vaste focus aan boord. Hij heeft vergelijkbare specificaties als de originele RPi camera, maar is niet zo high-res als de nieuwe RPi camera v2!Specificaties Afmetingen cameramodule: 8,6 x 8,6 mm Diameter lens: 10 mm Totale lengte: 60 mm Openingshoek lens: 160 graden Gewicht: 1,9 g

The Robotics Board features 2 Dual H Bridge Motor Driver ICs. These are capable of driving 2 standard motors or 1 stepper motor each, with full forward, reverse, and stop control. There are also 8 servo outputs, capable of driving standard and continuous rotation servos. They can all be controlled by the Pico using the I²C protocol, via a 16 channel driver IC. The IO break out provides connections to all the unused pins on the Pico. The 27 available I/O pins allow other devices, such as sensors or ZIP LEDs, to be added to the board. Power is provided via either a terminal block or servo style connector. The supply is then controlled by an on/off power switch to the board and there is also a green LED to indicate when the board has power. The board then produces a regulated 3.3V supply which is fed into the 3 V and GND connections to power the connected Pico. This removes the need to power the Pico separately. The 3 V and GND pins are also broken out on the header, which means external devices can also be powered. To use the robotics board, the Pico should be firmly inserted into the dual row pin socket on the board. Ensure the Pico is inserted with the USB connector at the same end as the power connectors on the robotics board. This will allow access to all of the board functions and each pin is broken out. Features A compact yet feature-packed board designed to sit at the heart of your Raspberry Pi Pico robotics projects. The board can drive 4 motors (or 2 stepper motors) and 8 servos, with full forward, reverse, and stop control. It also features 27 other I/O expansion points and Power and Ground connections. The I²C communication lines are also broken out allowing other I²C compatible devices to be controlled. This board also features an on/off switch and power status LED. Power the board via either a terminal block or servo style connector. The 3V and GND pins are also broken out on the Link header, allowing external devices to be powered. Code it with MicroPython or via an editor such as the Thonny editor. 1 x Kitronik Compact Robotics Board for Raspberry Pi Pico Dimensions: 68 x 56 x 10 mm Requires Raspberry Pi Pico board

Inside the RP2040 is a 'permanent ROM' USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – Adafruit uses the technique on all thier native-USB boards. Just note you don't double-click reset, instead hold down BOOTSEL during boot to enter the bootloader!The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!For peripherals, there are two I²C controllers, two SPI controllers, and two UARTs that are multiplexed across the GPIO – check the pinout for what pins can be set to which. There are 16 PWM channels, each pin has a channel it can be set to (ditto on the pinout).Technical Specifications Measures 2.0 x 0.9 x 0.28' (50.8 x 22.8 x 7 mm) without headers soldered in Light as a (large?) feather – 5 grams RP2040 32-bit Cortex M0+ dual core running at ~125 MHz @ 3.3 V logic and power 264 KB RAM 8 MB SPI FLASH chip for storing files and CircuitPython/MicroPython code storage. No EEPROM Tons of GPIO! 21 x GPIO pins with following capabilities: Four 12 bit ADCs (one more than Pico) Two I²C, Two SPI and two UART peripherals, one is labeled for the 'main' interface in standard Feather locations 16 x PWM outputs - for servos, LEDs, etc The 8 digital 'non-ADC/non-peripheral' GPIO are consecutive for maximum PIO compatibility Built in 200 mA+ lipoly charger with charging status indicator LED Pin #13 red LED for general purpose blinking RGB NeoPixel for full color indication. On-board STEMMA QT connector that lets you quickly connect any Qwiic, STEMMA QT or Grove I²C devices with no soldering! Both Reset button and Bootloader select button for quick restarts (no unplugging-replugging to relaunch code) 3.3 V Power/enable pin Optional SWD debug port can be soldered in for debug access 4 mounting holes 24 MHz crystal for perfect timing. 3.3 V regulator with 500mA peak current output USB Type C connector lets you access built-in ROM USB bootloader and serial port debugging RP2040 Chip Features Dual ARM Cortex-M0+ @ 133 MHz 264 kB on-chip SRAM in six independent banks Support for up to 16 MB of off-chip Flash memory via dedicated QSPI bus DMA controller Fully-connected AHB crossbar Interpolator and integer divider peripherals On-chip programmable LDO to generate core voltage 2 on-chip PLLs to generate USB and core clocks 30 GPIO pins, 4 of which can be used as analog inputs Peripherals 2 UARTs 2 SPI controllers 2 I²C controllers 16 PWM channels USB 1.1 controller and PHY, with host and device support 8 PIO state machines Comes fully assembled and tested, with the UF2 USB bootloader. Adafruit also tosses in some header, so you can solder it in and plug it into a solderless breadboard.

Simply put, when it comes to electronics design and programming, the more topics you can master, the more you’ll flourish at your workplace and at your personal workbench. This shouldn’t be a surprise, as the line between the skills of a hardware engineer and software engineer is blurring. The former should have a good grasp of programming in order to build efficient systems. The latter should understand the details of the design (whether it’s a physical or virtual application) for which he or she is writing code. Thus, to be successful, a modern professional electronics engineer must have a solid grasp of both hardware design and programming. Assembly Language Essentials is a matter-of-fact guide to Assembly that will introduce you to the most fundamental programming language of a processor. Unlike other resources about Assembly that focus exclusively on specific processors and platforms, this book uses the architecture of a fictional processor with its own hardware and instruction set. This enables you to consider the importance of Assembly language without having to deal with predetermined hardware or architectural restrictions. You’ll immediately find this thorough introduction to Assembly to be a valuable resource, whether you know nothing about the language or you have used it before. The only prerequisite is that you have a working knowledge of at least one higher-level programming language, such as C or Java. Assembly Language Essentials is an indispensible resource for electronics engineering professionals, academics, and advanced students looking to enhance their programming skills. The book provides the following, and more: An introduction to Assembly language and its functionality Significant definitions associated with Assembly language, as well as essential terminology pertaining to higher-level programming languages and computer architecture Important algorithms that may be built into high-level languages, but must be done the “hard way” in Assembly language — multiplication, division, and polynomial evaluation A presentation of Interrupt Service Routines with examples A free, downloadable Assembler program for experimenting with Assembly

A Toolbox for Audio Lovers and Engineers Without any ambition to reach scientific levels, this book aims to be a toolbox for both audio lovers and high-end equipment designers. The elementary theory presented is the bare minimum for readers to grasp the operation and practical use of electrical, electromagnetic, physics, and electronic operations available in the designers’ toolbox. Each tool is explained in a minimum of words and theory without needless coverage of underlying equations or figures. The book chapters guide you through the process of designing quality amplifiers with vacuum tubes, from the very beginning, considering both technical and subjective requirements – in theory and practice. The book is a compilation of the author’s notes used in his professional and educational career but was nevertheless primarily written as a result of true love for the audiophile hobby.
