Did you know that ...? Is the metronome a device that emits regular auditory and visual signals, marking equal time intervals? It is of two types: mechanical, with a pendulum swinging back and forth, and electronic. It has been used for centuries, but only in 1815, the German inventor Johann Maelzel patented it as a musical instrument. Since then, it has been widely used by most artists to keep the right tempo or recordings.
What does the book present?
This book is for electronics enthusiasts interested in developing projects that can be both fun and useful.
Most of the projects presented in the book can be built in a relatively short time using only a few components. Many of the pieces can be recovered from old radios and televisions. Each project presented contains a list of parts, electronic diagram and description of functionality.
Projects in this book, which include an AM radio, an FM radio, relay controls, audio amplifiers, oscillators and test equipment - are each designed with just two types of transistors. Building these transistor projects will be both fun and educational.

Did you know that that old electronic metronome never worked right? I needed it, it would have been a useful tool, I built it and made it. That's why I say. After a long time I found a mechanical one, something else but it worked.
