I only gave this book four stars due to it's lack of digital circuits. It will take you far, however. It has some great projects like power supplies,audio amps,logic probe,novelty astable squeakers, hum reducers. However, it odesn't have anything on multiplexing and the MODULATION RF PROPAGATION is SCANT.
Use it for formula and for golden rules of the breadboard. Ohm, Kirchoff,bi stable device, transistor /semiconductor theory,block diagramming,ac/dc rectification & dc/ac inversion. Don't expect anything on bridge circuits or theories behind the math like thevenin theory or norton. Which are the mainstay for college level quizzes.
