Title
How to Understand, Present and Invent Electronic Circuits
Description
This site presents a completely novel concept in electronics education as an alternative to the classical approach. Based on human imagination and intuition rather than formal reasoning, it is implemented as an interactive multimedia electronics product. It is intended for students, teachers, hobbyists, inventors and for all those who do not make do with traditional formal explanations of electronic circuit phenomena. The product consists of tutorials, collections of circuits, basic principles and heuristic tools implemented by means of dynamic text, interactive step-by-step controlled animations, hyperlinks, hidden explanation buttons and sounds associated to the circuit operation. Created by Cyril Mechkov.
