Description

Most children are interested in electrical appliances, observe how a light bulb, remote control car or music player works. When they decide to check what they are hiding inside, they often fall victim to a gadget. It is worth showing them that electronics gives the most joy and knowledge when you build something with your own hands! It is precisely the construction of more and more complicated circuits that is extremely addictive and gives great satisfaction.

This book is intended for young and slightly older electronics enthusiasts. There is a large collection of practical projects to be done on your own, supplemented by explanations of theoretical issues. There is no shortage of tips on how to choose a component, and where to buy it. Thanks to building circuits and studying their operation by hand, the understanding of the physical phenomena taking place comes virtually automatically. The proposed designs are very diverse: from the simplest electrical circuits to quite complex electronic circuits.

Thanks to the information contained in this book you will build them:

  • electromagnet and electric motor
  • power generator and battery
  • Touch detection circuit and alarm clock to detect sunrise
  • a message encryption machine
  • player reflex testing game
