|Here's the book for every hobbyist who wants to be an inventor, but needs
to learn the basics of electronics to get there. In most introductory electronics books
the emphasis is on technical formulas and theory, while practical applications and advice
often get lost in a high-tech haze. Not very inspiring...
Practical Electronics for Inventors gives you information you need, in a format you can work with. The simple step-by-step approach teaches the fundamentals in a way that requires no background in electronics. Packed with illustrations, the 750 hand-drawn images provide clear, detailed instructions on how to turn theoretical ideas into working real-life gadgets.
This crystal-clear, learn-as-you-go guide shows you what a particular device does, what it looks like, how it compares with similar devices, and how it is used in applications. Written by Paul Scherz, a physicist who is also an inventor and electrical hobbyist, this important reference provides beginning hobbyists and inventors with an intuitive grasp of the theoretical and practical aspects of electronics--just the kind of insight you need to get your projects up and running.
Starting with a light review of electronics history, physics, and math, the book
provides an easy-to-understand overview of all major electronic elements. Along with
coverage of integrated circuits (ICs), digital electronics, microcontrollers, and various
input/output devices, Practical Electronics for Inventors takes you through
reading schematics; building and testing prototypes; purchasing electronic components; and
safe work practices. You'll find all this--and more--in the guide that's destined to spur
you on to new levels of creativity.
Chapter 1: Introduction to Electronics
Perhaps the most common predicament a newcomer faces when learning electronics is figuring out exactly what it is he or she must learn. What topics are worth covering, and in which general order should they be covered? A good starting point to get a sense of what is important to learn and in what general order is presented in the flowchart in Fig. 1.1.
This chart provides an overview of the basic elements that go into designing practical electrical gadgets and represents the information you will find in this book. The following paragraphs describe these basic elements in detail.
At the top of the chart comes the theory. This involves learning about
voltage, current, resistance, capacitance, inductance, and various laws and theorems that
help predict the size and direction of voltages and currents within circuits. As you learn
the basic theory, you will be introduced to basic passive components such as resistors,
capacitors, inductors, and transformers.
