A Combat Guide against E-waste and Throwawayism
This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste.
E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project.
Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.
The PC has long-time outgrown its function as a pure computer and has become an all-purpose machine. This book is targeted towards those people that want to control existing or self-built hardware from their computer.
Using Visual Basic as Rapid Application Development tool we will take you on a journey to unlock the world beyond the connectors of the PC.
After familiarising yourself with Visual Basic, its development environment and the toolset it offers, items such as serial communications, printer ports, bit-banging, protocol emulation, ISA, USB and Ethernet interfacing and the remote control of test-equipment over the GPIB bus, are covered in extent. Each topic is accompanied by clear, ready to run code, and where necessary, schematics are provided that will get your projects up to speed in no time.
This book will show you advanced things like: using tools like Debug to find hardware addresses, setting up remote communication using TCP/IP and UDP sockets and even writing your own internet servers. Or how about connecting your own block of hardware over USB or Ethernet and controlling it from Visual Basic. Other things like internet-program communication, DDE and the new graphics interface of Windows XP are covered as well.
All examples are ready to compile using Visual Basic 5.0, 6.0, NET or 2005. Extensive coverage is given on the differences between what could be called Visual Basic Classic and Visual basic .NET / 2005.

Learn to 3D Model & 3D Print with Tinkercad
With this book and the complementary videos, you’ll be 3D printing in no time at all. This course is meant to have you make casings for electronic components but also goes into optimizing your print technique as well as adding a little flair to your 3D creations. The course is perfect for you if you just bought your (first) 3D printer and want to print your own designs as soon as possible while also being able to get more background information.
You’ll get to know the workings of a 3D printer and what software to use to model your object, not forgetting to make it print perfectly. We’ll even use the magic of 3D printing to create things that appear impossible to make (this fast and simple) with any other rapid-prototyping technique.
At the end of this course, it’ll be second nature for you to design an object for 3D printing and fine-tune your print-setting to get the perfect print!
The book includes the following 7 video tutorials:
Introduction
Basic 3D modeling for 3D printing
Modeling a casing
Post-processing

Un peu d'électronique et beaucoup d'experimentation : un livre ludique !
Gravité, réfraction, couleurs, vitesse du son, pendule, masse, élasticité, pression, aimants : une approche nouvelle et créative des leçons de physique
Matériel peu coûteux et facilement disponible
Logiciels gratuits
Kit disponible séparément
La rencontre de la physique et du microcontrôleur ne devrait plus étonner personne. Il existe d’excellents enregistreurs de données, ainsi que de nombreux programmes pour les traiter et les présenter sous forme de graphiques colorés et attrayants. La physique rébarbative, c’est fini !
J’ai choisi l’Arduino, car cette plate-forme est d’un accès facile et sa documentation abondante. La famille Arduino offre des ressources extraordinaires à un prix dérisoire. Ajoutez-y le logiciel gratuit CoolTerm, et vous pouvez enregistrer toutes les données de mesure pour les retravailler sous Excel et créer aisément des tableaux ou des graphiques.
Ce livre n’est pas un manuel de physique. Vous n’y trouverez ni équations différentielles ni courbes abstraites. Nous étudierons des phénomènes physiques de la vie de tous les jours. Sans chercher à être exhaustif, mon modeste ouvrage apporte aux leçons de physique une approche nouvelle et créative grâce aux techniques modernes de mesure et de traitement des données. L’électronique utilisée est simple, et constitue une belle démonstration des possibilités.

The Basics, New Ideas & Applications
Build digital electronics from the ground up—and take it all the way to practical circuits you can use.
This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on.
From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits.
Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs.
Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters.
Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.
