According to the program of the Summer Scientific and Specialized School of the Department of Engineering and Materials Science of the Kyiv Small Academy of Sciences of Student Youth 2025, we held classes with senior students of Kyiv schools. We continue to open the world of electronics and engineering to them, giving them the opportunity not only to theoretically master the material, but also to create and test electronic devices on their own. This time, the students made models of a random number generator.
The assembly process turned out to be not only interesting, but also informative. Despite the relative simplicity of the circuits, which required only two dozen soldering points, not all devices worked on the first try. This provided an excellent opportunity to practice attentiveness when searching for and correcting soldering defects under a magnifying camera, using a multimeter to diagnose the power supply of components - all this helped the students to better understand the principles of electronics, to gain experience working with the "magic wands" of an electronics engineer.
After all, the moment when the assembled circuit starts working brings not only satisfaction, but also a real sense of achievement. This is exactly the experience that ignites interest in technical disciplines and motivates further learning.
