A Handbook on DIY Nowadays, security problems are rarely properly solved or correctly addressed. Electronic security is only part of the chain in making a system secure. Electronic security is usually addressed as network or software security, neglecting other aspects, but the chain is only as strong as its weakest link. This book is about electronic hardware security, with an emphasis on problems that you can solve on a shoestring DIY budget. It deals mostly with secure communications, cryptosystems, and espionage. You will quickly appreciate that you can’t simply buy a trustworthy and reliable cryptosystem off the shelf. You will then realise that this applies equally to individuals, corporations, and governments. If you want to increase your electronic security awareness in a world already overcrowded with networks of microphones and cameras, this is a book for you. Furthermore, if you want to do something DIY by designing and expanding upon simple electronic systems, please continue reading. Some of the devices described are already published as projects in the Elektor magazine. Some are still ideas yet to be worked out. Complexity is the main enemy of security, so we'll try to keep to simple systems. Every chapter will analyse real-life espionage events or at least several hypothetical scenarios that will hopefully spark your imagination. The final goal is to build a security-conscious mindset (or “to get into a head of a spy”) which is necessary to recognise possible threats beforehand, to design a truly secure system. Don’t bother reading if: you think you and your secrets are 100% safe and secure you think somebody else can effectively handle your security you think conspiracy theories only exist in theory – Telefunken’s masterpiece the “FS-5000 Harpoon” was built on one!

La mesure des émissions conduites est la méthode la plus simple et la plus abordable pour savoir si une conception peut répondre aux exigences IEM/CEM. Le Réseau de Stabilisation d'Impédance de Ligne (RSIL ou LISN en anglais) est un composant indispensable d'une installation de test de préconformité CEM. En coopération avec Würth Elektronik, Elektor a conçu un RSIL CC double de 5 µH, 50 Ω qui supporte des tensions jusqu'à 60 V et des courants jusqu'à 10 A. L'appareil mesure les interférences RF sur les deux canaux (l'alimentation) au moyen d'inductances de blocage de 5 μH. Le réseau interne d'atténuation de 10 dB – un dans chaque canal – contient un filtre passe-haut de 3e ordre avec une fréquence de coupure de 9 kHz pour protéger l'entrée d'instruments tels qu'un analyseur de spectre contre les tensions continues ou les basses fréquences potentiellement dangereuses provenant de l'EST (Équipement Sous Test).

Les mots-clés du magazine ELEX publié par Elektor sont ÉLECTRONIQUE – EXPÉRIMENTATION – EXPLORATION. L'électronique est une discipline originale qui consacre l'essentiel de ses efforts à se perfectionner elle-même, mais la connaissance de ses principes et de ses fondements reste cruciale. L'expérimentation est fondamentale aussi, parce que c'est le goût de la manipulation qui, un jour lointain, de chiffons mouillés et de quelques plaques de métal a fait la première pile électrique. L'exploration, parce que pour guider l'expérimentation, il y a la passion de l'inconnu, la soif de comprendre, l’obstination, le sens de l'effort (souvent) gratuit. Tout ce qui fait la différence entre passion et indifférence. ELEX c'est : Rési & Transi (deux personnages d’une géniale bande dessinée d'initiation à l’électronique) mais aussi les rubriques Analogique Anti-Choc, Logique sans hic ou encore Mesure & Labo. Ce sont aussi des centaines de réalisations (audio, auto & moto & vélo, maison, jeux, bruitage, mini-circuits, modélisme, photo, radio & HF) etc. Bonus vidéo sur cette clé USB : 'Rési et Transi dans La conquête de l'électronique', un film de quatre épisodes autour de la réalisation d'un mini-orgue électronique.

An Introduction to RISC-V RISC-V is an Instruction Set Architecture (ISA) that is both free and open. This means that the RISC-V ISA itself does not require a licensing fee, although individual implementations may do so. The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions. After the description of the CPU design is complete the design is expanded to include memory and some simple I/O. The resulting microcontroller will then be implemented in an affordable FPGA development board (available from Elektor) along with a simple software application so that the reader can investigate the finished design.

Projets avec Thonny-IDE, uPyCraft-IDE et ESP32 Le langage de programmation « Python » a connu un énorme essor ces dernières années. Enfin, divers systèmes monocarte tels que le Raspberry Pi ont contribué à sa popularité. Mais Python a également été largement utilisé dans d’autres domaines, comme l’intelligence artificielle (IA) ou l’apprentissage automatique (ML). Il est donc évident d'utiliser également Python ou la variante « MicroPython » pour une utilisation dans les SoC (Systems on Chip). Des contrôleurs puissants tels que l'ESP32 d'Espressif Systems offrent d'excellentes performances ainsi que des fonctionnalités Wi-Fi et Bluetooth à un prix abordable. Avec ces fonctionnalités, la scène Maker a été prise d’assaut. Comparé à d'autres contrôleurs, l'ESP32 dispose d'une mémoire Flash et SRAM nettement plus grande, ainsi que d'une vitesse de processeur beaucoup plus élevée. Grâce à ces caractéristiques, la puce convient non seulement aux applications C classiques, mais également à la programmation avec MicroPython. Ce livre présente l'application des systèmes modernes à puce unique. En plus du contexte technique, l'accent est mis sur MicroPython lui-même. Après l’initiation au langage, les compétences en programmation acquises sont immédiatement mises en pratique. Les projets individuels conviennent aussi bien à une utilisation en laboratoire qu'à des applications quotidiennes. Ainsi, outre l’effet d’apprentissage réel, l’accent est également mis sur le plaisir de construire des appareils complets et utiles. En utilisant des planches à pain de laboratoire, des circuits de toutes sortes peuvent être réalisés avec peu d'effort, transformant les tests et le débogage des projets 100 % homebrew en un plaisir instructif. Les différentes applications, telles que les stations météorologiques, les voltmètres numériques, les télémètres à ultrasons, les lecteurs de cartes RFID ou les générateurs de fonctions, rendent les projets présentés parfaitement adaptés aux cours pratiques ou aux travaux de matières et d'études en sciences naturelles ou aux cours de sciences et technologies.
