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!

This kit includes iFixit's widest assortment of bits, complete with every driver head you’ll need to tackle any repair or DIY project. It includes standard bits like Phillips and Flathead in a full range of sizes to handle everything from precision electronics repair to home DIY projects. And it wouldn’t be an iFixit bit set if it didn’t include all the exotic bits from Pentalobes for Apple iPhone and MacBook repair to Gamebits for your vintage Nintendo consoles. All of the next-gen bit sets have been re-designed in order to maximize convenience and usability. The bit set lid is held in place with magnets to increase product lifespan (no more broken hinges or clasps) and also mounts to the back of the bit set case to keep it out of the way while you do your work. If you need help keeping your screws and parts organized, you can use the lid’s integrated sorting tray. The 4 mm bits have been adjusted and have now a longer neck for a deeper and more precise reach. Toolkit Includes Easy-to-Open Magnetized Case Lid with Built-in Sorting Tray 4 mm Aluminum Bit Driver 1/4' Aluminum Bit Driver 4 mm Screwdriver Bits Phillips - 000, 00, 0 Flathead - 1, 1.5, 2, 2.5, 3, 3.5 mm Torx - T2, T3, T4, T5 Torx Security - TR6, TR7, TR8 Pentalobe - P2, P5, P6 JIS - 000, 00, 0, 1 Hex - 0.7, 0.9, 1.3, 1.5 mm Hex Security - 2, 2.5, 3, 3.5 mm Tri-point - Y000, Y00, Y0, Y1 Nut driver - 2.5, 3, 3.5, 4, 4.5, 5, 5.5 mm Gamebit - 3.8, 4.5 mm Spanner - 4, 6 Triangle - 2, 2.2, 2.6, 3 mm Oval Bit iPhone Standoff Bit Sim Eject Bit Magnetic Pickup Bit 1/4' Screwdriver Bits Phillips - 1, 2, 3 Flathead - 4, 5, 6, 7, 8 mm Hex Security - 4, 5, 6, 7, 8 mm Hex Security SAE - 1/8, 9/64, 5/32, 3/16, 7/32, 1/4 Pozidriv - PZ0, PZ1, PZ2, PZ3 Torq-set - 6, 8, 10 Spanner - 8, 10, 12 Square - 0, 1, 2, 3 Spline - M5, M6, M8 Torx Security - TR9, TR10, TR15, TR20, TR25, TR27, TR30, TR35, TR40 Tri-wing 1, 2, 3, 4 Clutch 1, 2, 3 Schrader Valve Hook Drive 1/4' to 4 mm Adapter 1/4' Driver to 1/4' Socket 1/4' Driver to 3/8' Socket 1/4' Socket to 1/4' Driver Specifications Bit Metal: 6150 Steel Driver Material: Anodized Aluminum Case Material: ABS Foam: EVA

Eine Einführung in die Schaltungssimulation LTspice wurde von Mike Engelhardt entwickelt und gehört inzwischen zu Analog Devices. Es handelt sich dabei um ein Programm zur Schaltplanerstellung – einen leistungsstarken, schnellen und kostenlosen SPICE-Simulator sowie um ein Werkzeug zur Darstellung von Kurvenverläufen. Es bietet eine umfangreiche Bauteildatenbank, die weltweit durch SPICE-Modelle unterstützt wird. Mit LTspice kann man schnell und einfach Schaltpläne erstellen. Dank der leistungsfähigen grafischen Ausgabefunktionen lassen sich Spannungen und Ströme in einer Schaltung, die Leistungsaufnahme der Bauteile und viele weitere Parameter darstellen. Ziel dieses Buches ist es, den Entwurf und die Simulation elektronischer Schaltungen mit LTspice zu vermitteln. Es behandelt unter anderem folgende Themen: DC und AC-Schaltungen Kleinsignal- und Z-Dioden Transistorschaltungen inkl. Oszillatoren Tryristor-, Diac- und Triacschaltungen Operationsverstärkerschaltungen inkl. Oszillatoren Der 555 Timer-IC Filter Spannungsregler Optokoppler Erstellung von Spannungskurven Simulation von Logikschaltungen mit der 74HC-Familie SPICE-Modellierung LTspice ist ein äußerst vielseitiges Werkzeug zur Simulation elektronischer Schaltungen mit zahlreichen Funktionen und Anwendungsmöglichkeiten. Eine vollständige Behandlung aller Details würde jedoch den Rahmen dieses Buches sprengen. Daher konzentriert sich das Buch auf die gängigsten Themen wie DC- und AC-Analyse, Parametersweep, Übertragungsfunktionen, Oszillatoren, Diagramme und weitere grundlegende Anwendungen. Obwohl es sich um eine Einführung handelt, deckt dieses Buch dennoch die meisten Interessensgebiete all jener ab, die sich mit der Simulation elektronischer Schaltungen beschäftigen.
