50 Electronic Projects

Electronic Projects for Beginners has been written for a wide cross-section of readers in ITI and diploma level students looking for suitable project exercise to be done as a part of their academic curriculum, hobbyists and electronics enthusiasts. The book has been written in a very simple language with large number of illustrations and contains in one volume both the detailed account of projects as well as the relevant theory in the form of three introductory chapters in order to enable the users of the book fully understand what they are attempting to build.

The book contains 50 projects in all complete with comprehensive functional description, parts lists, construction details such as PCB and components' layouts, testing guidelines, suitable alternatives in case of uncommon components and lead / pin identification guidelines in case of semiconductor devices and integrated circuits (ICs). The first three introductory chapters contain a lot of practical information. The first chapter gives operational basics and application relevant information in case of electronic components such as Resistors, Capacitors, Coils, Transformers, Diodes, Transistors, LEDs, Displays, SCRs, Opamps, Timers, Voltage Regulators and General Purpose digital ICs such as Gates, Flip flops, counters, etc.

The second chapter on constructional guidelines gives a brief account of soldering techniques, PCB making guidelines and guidelines to using general purpose test and measuring equipment such as Ammeters, Voltmeters, Analog and Digital multimeters, Oscilloscopes, etc. The third chapter is a glossary of popular types of general purpose Linear and Digital Integrated Circuits to enable you make a quick and correct choice of linear or digital IC that you are looking for. The three introductory chapters followed by detailed description of 50 tested projects thus make the book a true self-learning guide for those who wish to construct electronics projects.
