PDF "Robert M. Brown - 104 EASY Projects for the Electronics Gadgeteer"
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.
