This could very well be a publishing first—a book devoted to the premise that most of the real fun in electronic tinkering is derived from scrounging and swiping, trial and error, and good, old - fashioned cheap - skating. You'll be surprised at the useful and fun things you can put together with a little imagination and available components. You'll be even more surprised when you realize what can be done without tubes or transistors! The purpose of this book is to give you some food for thought along these lines and to clue you in on some tricks of the trade in getting the most for the least.

The purpose of this book is to provide a number of useful and interesting electronic constructional projects for use in and around the workshop. The projects will have considerable appeal to the home handyman and will find use in the average "Do It Yourself" workshop. Many of the circuits are very versatile, and could easily be adapted to perform d ...
Originally published by the Radio Society of Great Britain, the projects were all chosen to be useful and straightforward, with the emphasis on practicality. In most cases the workings of the circuit are described, and the projects are backed up by small tutorials on the components and concepts employed.
21 assorted electronic circuits designed for a dedicated (originally supplied with the book) circuit board. There are however diagrams for each of the circuits enabling them to be built on Veroboard or similar. Also included in the book are instructions for making the PCB if required.
This ebook is specially written for anyone who interesting in electronic. It has 25 projects. There are simple to build and understand. It uses breadboard to build the different electronic circuits in the projects.
