Multilingual DIY Kit (incl. 27 RGB LEDs + Raspberry Pi Pico) Bring some engineering magic to your festive season with the Wordy LED Christmas Tree, a unique DIY electronics kit designed by Elektor. This beautifully engineered 3D Christmas tree combines eleven PCBs, a Raspberry Pi Pico, and 27 addressable RGB LEDs to illuminate Christmas greetings in seven languages: Danish, Dutch, English, French, German, Italian, and Spanish. Unlike ordinary LED trees, each word inside the tree has its own light chamber, creating a refined, softly glowing display without sound or flicker. The LEDs are fully WS2812-compatible and driven via the popular Adafruit NeoPixel library, making custom animations and color effects easy to create. Perfect for makers, tinkerers, and festive electronics fans, this kit offers both an enjoyable build and a striking, conversation-worthy decoration. The Wordy Christmas Tree is your perfect holiday maker project! Features Multilingual greetings (7 languages) milled into the front panel 3D construction from 11 interlocking PCBs Powered by Raspberry Pi Pico 27 individually addressable RGB LEDs (pre-mounted) Smooth fade-in and fade-out animations Fully programmable using the Arduino IDE A 5-V power supply (with micro-USB connector) capable of ≥1 A is recommended for maximum brightness (not included) Dimensions (H x W x D): 130 x 115 x 75 mm Included All required PCBs with LEDs and other SMD parts mounted Raspberry Pi Pico (to be soldered & programmed by the user) 3-way pin header (to be soldered by the user) 3-way pin socket (to be soldered by the user) 4x Self-adhesive dome bumpers Project Page Elektor Labs

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.

The Internet of Things is rapidly gaining interest, and that has fueled the development of the Edison. A tiny computer, the size of a postage stamp, with a lot of power and built-in wireless communication capabilities. In this eBook we will help you get up-to-speed with the Edison, by installing the software both on the Edison as well as on your Windows PC. We will use the Edison Arduino break-out board because it is easy to work with. We will discuss Linux, Arduino C++ and Python, and show examples of how the Edison can interface with other hardware. We will use Wi-Fi and Bluetooth to set up wireless connections, and show you a trick to program sketches over Wi-Fi. Once you have completed this book your Edison will be up and running with the latest software version, and you will have sufficient knowledge of both hardware and software to start making your own applications. You will even be able to program the Edison over USB and wireless both in Arduino C++ and Python. This is not a projects eBook, but a toolbox that will allow you to explore the wonderful world of the Intel Edison!

Learn to program displays and GUIs with Python This book is about Raspberry Pi 4 display projects. The book starts by explaining how to install the latest Raspbian operating system on an SD card, and how to configure and use the GPIO ports. The core of the book explains the following topics in simple terms with fully tested and working example projects: Simple LED projects Bar graph LED projects Matrix LED projects Bitmap LED projects LED strips LCDs OLED displays E-paper displays TFT displays 7-inch touch screen GUI Programming with Tkinder One unique feature of this book is that it covers almost all types of display that readers will need to use in their Raspberry Pi based projects. The operation of each project is fully given, including block diagrams, circuit diagrams, and commented full program listings. It is therefore an easy task to convert the given projects to run on other popular platforms, such as Arduino or PIC microcontrollers. Python program listings of all Raspberry Pi projects developed in this book are available for download at Elektor.com. Readers can use these programs in their projects. Alternatively, they can modify the programs to suit their applications.
