Introduction
This book is for you experimenters and makers who want to design your own electronic circuits and equipment. There are not too many books like this. Most books tell you how electronic devices work and provide some projects to learn from. But now you have in your hands a book that is actually going to show you how to design your own electronic circuits and equipment. It is written in a way so that any of you who have a background in electronic fundamentals can create a circuit or device to do something you want to do. You dont have to be an engineer to design things.
With the knowledge and procedures in this book, you can create products for resale, implement scientific projects that need special equipment, or produce circuits for your own DIY (do-it-yourself) idea. The book relies upon the availability of popular integrated circuits and the many finished modules and subassemblies. Using existing products and legacy circuits eliminates most of the difficult circuit design. In many cases, you can piece together existing circuits and modules to make a device with minimal electronic design. However, some basic circuit design is usually necessary and hopefully, this book will help with that.
The design approach in this book focuses on making a working device using standard parts and circuits. The recommendations in each chapter suggest that you use chips and circuits that have been used before. Why reinvent the wheel? The result is lesser design time and greater success at lower cost. Your design may not always be leading-edge but it will do the job.
You Are the Target Audience
When writing this book, I had the following people in mind:
Hobbyists, experimenters, DIYers, and makers who want to create their own equipment.
New engineersgraduates who are well versed in math, physics, and electronic fundamentals but have not yet learned to apply that knowledge to creating products.
Technicians who are knowledgeable in electronics but have not designed.
Scientists like physicists, chemists, geologists, and other users of electronic equipment who often need custom noncommercial equipment but can learn to design their own.
Students who can supplement their theoretical studies with practical design knowledge. Students in an introductory college design course or taking a design capstone course or culminating design project course where the theory is applied to a specific circuit or device.
It is likely that you are part of one those groups.
Book Rationale
Where does one generally go to learn electronic design? At colleges or universities offering a BSEE degree, of course. These institutions teach all the science, math, theory, components, and circuits. Some courses actually teach related design. Much of the design taught in college is how to design integrated circuits using special software created for that purpose. Yet, many colleges and universities rarely address modern practical product design. There is a need to learn how to translate theory into practice by creating useful end products. This book addresses that void. It is unique and serves a need. Not everyone can go to college, but that does not mean you cannot learn design. In fact, in the real world BSEE graduates go out to jobs and that is where they really learn the design process. On the job training (OJT) is where you get actual design experience. Now you can get a taste of that with this book.
