Getting started with the world’s best open-source PCB tool The latest iteration of KiCad, the world’s best free-to-use Printed Circuit Board tool, is packed with features usually found only in expensive commercial CAD tools. This modern, cross-platform application suite built around schematic and design editors, with auxiliary applications is a stable and mature PCB tool. KiCad 8 is a perfect fit for electronic engineers and makers. Here are the most significant improvements and features in KiCad 8, both over and under the hood: Modern user interface, completely redesigned from earlier versions Improved and customizable electrical and design rule checkers Theme editor allowing you to customize KiCad on your screen Ability to import projects from Eagle, CADSTART, and more Python scripting API Improved integrated SPICE circuit simulator Multi-sheet schematics Filters define selectable elements Enhanced interactive router helps you draw single tracks and differential pairs with precision New or enhanced tools to draw tracks, measure distances, tune track lengths, etc. Advanced interactive router Built-in bill of materials generator Realistic ray-tracing capable 3D viewer Customizable teardrops Plug-in manager for quick installation of themes, libraries and functionalities such as autorouters and BOM generators This book will teach you to use KiCad through a practical approach. It will help you become productive quickly and start designing your own boards. Example projects illustrate the basic features of KiCad, even if you have no prior knowledge of PCB design. The author describes the entire workflow from schematic entry to the intricacies of finalizing the files for PCB production and offers sound guidance on the process. Further full-fledged projects, of incremental difficulty, will be presented in a second book, together with a variety of advanced recipes.

Plot, Cut, Drill, Mill and Laser with the Z99 This book covers the construction, hardware, software, and operation of the Z99 – CNC machine. This is a multifunctional 4-axis machine for home construction. The capabilities of the Z99 machine include: large-format schematic plotting PCB plotting with etch-resist pens schematic plotting with conductive-ink pens letter cutting out of vinyl paper cutting PCB/substrate drilling PCB/substrate milling text milling laser engraving laser cutting of solder paste masks By making the support software available as freeware, readers of the book are challenged and encouraged to develop new applications for the Z99. The machine would not be of much use if the user has no option to create suitable files for the designs in mind. A large part of this book is dedicated to creating source files in a variety of freeware software packages, including Inkscape, DesignSpark PCB, KiCad, and FlatCAM. The book is also useful for readers keen to comprehend and then master the basic structure of HPGL, Gerber, Drill, and G-code files, as well as to have a go at deciphering them using software.

L'alimentation de laboratoire à faible bruit d'Elektor est une unité symétrique, entièrement analogique, réglable et de puissance moyenne, qui ne contient aucun composant à découpage ni composant numérique. Elle fournit une tension de sortie réglable entre 0 V et ±22 V, ainsi qu’un courant de sortie réglable de 0 A à 1 A. Comme elle évite toute forme de circuit à découpage, sa conception offre un bruit extrêmement faible. Pour afficher les deux tensions et courants de sortie, quatre petits indicateurs analogiques à cadre mobile sont utilisés. La plupart des alimentations de laboratoire modernes et des adaptateurs secteur utilisent des techniques à découpage. Même les meilleurs modèles présentent inévitablement une ondulation haute fréquence et d’autres artefacts de commutation en sortie, susceptibles de perturber les tests de circuits analogiques sensibles et les mesures de faibles signaux. Pour éviter cela, le concept présenté ici repose sur une alimentation entièrement analogique. Bien qu’elle soit moins efficace que ses homologues à découpage, cette efficacité réduite a peu d’importance pour une utilisation sur banc d’essai et garantit des résultats de mesure plus propres et plus fiables. Comme de nombreux circuits analogiques nécessitent une alimentation symétrique, ce modèle fournit des tensions de sortie positive et négative de même amplitude. Un léger réglage est disponible pour compenser tout déséquilibre éventuel. Naturellement, une fonction de limitation de courant réglable est également intégrée. Le kit comprend les composants nécessaires à la construction de l’alimentation, à l’exception des transformateurs.

EAGLE – the “Easily Applicable Graphical Layout Editor“ is a professional-grade CAD (computer aided design) software package for the design and drafting of electronic schematics as well as the design and fabrication of printed circuit boards (PCBs). This Advanced User Guide provides the experienced EAGLE user with insight into using some of the more advanced features of EAGLE software. It is not a guide to teach the reader the basic concepts of EAGLE, nor does it discuss the ‘how to’ of the EAGLE interface and the simpler operations and commands of the software. That is the purpose of the author’s previous title EAGLE V6 Getting Started Guide also published by Elektor. This eBook is intended as an enduring document covering the more advanced modules, commands, and functions which make up EAGLE. It is hoped that this eBook will provide a quick, succinct reference to assist with more complex applications and uses of EAGLE – an ‘EAGLE User’s Companion’, if you like. Complementing the EAGLE Advanced User Guide, the EAGLE User Language manual is included in this eBook in unabridged form, reproduced with permission of CadSoft GmbH. At the time of writing, the material in this eBook covers version 7 of the EAGLE software suite.

The newcomer to Microchip’s PIC microcontrollers invariably gets an LED to flash as their first attempt to master this technology. You can use just a simple LED indicator in order to show that your initial attempt is working, which will give you confidence to move forward. This is how the book begins — simple programs to flash LEDs, and eventually by stages to use other display indicators such as the 7-segment display, alphanumeric liquid crystal displays and eventually a colour graphic LCD. As the reader progresses through the book, bigger and upgraded PIC chips are introduced, with full circuit diagrams and source code, both in assembler and C. In addition, a small tutorial is included using the MPLAB programming environment, together with the EAGLE schematic and PCB design package to enable readers to create their own designs using the book’s many case studies as working examples to work from.
