Fascinating Electrical Engineering. Homemade Electrical Devices

How to get a strong current from a weak source? How can burnt-out bulbs be used? How to get heat without fire and make a homemade heater?
Answers to these and other questions can be found in Vladimir Ryumin's book, an experienced educator and engineer. It contains an extensive course on practical electrotechnics: from the first experiments with a Ruhmkorff coil to the basics of radio communication.

In the book:
- How to construct an “electric chair” for fighting flies?
- How to achieve the effect of X-rays without special equipment?
- What is the secret of the structure of matter?
- How to assemble a functioning telegraph using two old doorbells?

Logical presentation, absence of complex calculations, and a refined pedagogical system make the book a reliable classic, which still fosters an engineering mindset today. “Entertaining Electrotechnics. Homemade Electrical Devices” will be useful not only for schoolchildren, students, and teachers, but also for anyone who wishes to understand the devices around us and apply the laws of physics in everyday life.
