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.

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 bevat 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 Specificaties Bit Metal: 6150 Steel Driver Material: Anodized Aluminum Case Material: ABS Foam: EVA

35 Projects for Beginners This book is for hobbyists, students and engineers who want to learn C and how to use an mbed ARM microcontroller in an easy and fun way, without the need for cumbersome software installations. ARM mbed microcontroller NXP LPC1768 The projects in this book are meant for beginners in C and ARM microcontrollers. That doesn't mean the projects are simple, but it does mean that they are easy to understand. We use for example USB communications, a subject that is made so easy by the mbed that it is suitable for a beginners book. Cloud technology The mbed NXP LPC1768 uses cloud technology, a revolutionary concept in software development. This means you do not need to install software on your PC in order to program the mbed! The only thing you need is a browser such as Microsoft Internet Explorer, and a USB port on your PC. You can get access to your project from any PC anywhere in the world and continue working on it. When you are done a few simple mouse clicks transfer the program to your mbed hardware. Of course you can optionally download the projects and store them on your own PC. Features of this Book Learn how to program an mbed ARM microcontroller using cloud technology. No complicated software installation on your PC needed. Learn programming in C by doing fun and interesting projects. No previous experience or knowledge required. Examples of projects in this book: flashing light, timer, light activated switch, digital thermometer, people detector, USB communication, talking microcontroller, debugging, sound switch, and much more - 35 projects in total. Examples of C subjects in this book: variables, commands, functions, program execution, pointers (introduction).

This book is all about building your own DIY home control system. It presents two innovative ways to assemble such a system: By recycling old PC hardware – possibly extending the life of an old PC, or by using Raspberry Pi. In both cases, the main system outlined in this book will consist of a computer platform, a wireless mains outlet, a controller and a USB webcam – All linked together by Linux. By using the Raspberry Pi in conjunction with Arduino (used as an advanced I/O system board), it is possible to construct a small, compact, embedded control system offering enhanced capacity for USB integration, webcams, thermal monitoring and communication with the outside world. The experience required to undertake the projects within this book are minimal exposure to PC hardware and software, the ability to surf the internet, burn a CD-ROM and assemble a small PCB.
