This book examines several cases and examples of project development, selected with one pronounced goal - to demonstrate to readers a few useful stylish "things" that can be created using analog technology. Such examples encourage further study of analog electronics, and also demonstrate in which areas of technology analog electronics still retains its considerable potential. As examples of circuitry solutions were chosen: fan control circuit, designed to blow out a spark plug flame using a semiconductor diode as a temperature sensor, a sensor for the presence of blood-sucking flying insects using an IR diode and a phototransistor, an electric shock, developing voltage at output electrodes of the order of 1000 V when powering the circuit from batteries with a voltage of 18 V, voltage multiplier circuit and DC motor speed control circuit. The publication can be useful for beginner and intermediate radio amateurs, as well as junior students studying analog electronics.
