84 Practical IC Projects - RH Warring - Introducing Digital Circuits
Reading time: 2 minute The book explains and "classifies" integrated circuits in simple terms. It covers the various modes of operation of the simplest ICs (Op-Amps) and describes a whole range of electronic circuits based on cheap integrated circuits. The book contains 84 different electronic circuits.
ABCs of Varactors - Rufus Turner - What are varactor / varicap diodes?
Reading time: 2 minute The varactor diode or varicap diode is a special diode that has the characteristic of modifying its internal capacity as the voltage applied to the terminals varies. The advantage of the varivap diode (varactor) over a trimmer or a variable capacitor is that we can make very fine adjustments and we can get even very small capacities.
117 Practical IC Projects you can build - What are integrated circuits?
Reading time: 2 minute This book explains and "classifies" integrated circuits in simple terms, presenting 117 different projects that you can build.
50 (FET) Field Effect Transistor Projects - Common causes of damage to FET transistors
Reading time: 2 minute FET is a low-noise, high-gain, multi-use device and "dual gate FET" is a special utility for mixers and other applications. MOS-FET type transistors are very sensitive to static electricity, if they are with air terminals.
First Electrical Book for Boys - What is electricity?
Reading time: 2 minute What is electricity? Electricity is the name of something that no one has ever seen and whose nature is a mystery. You might ask, but don't we feel the electricity when we get a shock and we don't see it when it flashes sometimes? And the answer is no. We never see, feel or hear electricity.
125 Transistor Projects - Rufus Turner - What are "choke" filters?
Reading time: 3 minute These circuits are offered to the student who wants to configure and test typical circuits with their own instructions, to the designer who wants functional blocks ready to be incorporated in a system and to the hobbyist whose amateur interests will be served by preset, pre-tested circuits.
First Book of Radio and Electronics - Alfred Morgan
Reading time: 2 minute How does a phone work? Who invented the radio and how are its signals sent? If you want to know about all these things and much more, here is a necessary book for basic knowledge, with a less technical content, helping a lot to unravel some 'mysteries'.
49 Easy Transistor Projects - Sensitive Geiger Counter
Reading time: 2 minute Projects in this book, which include an AM radio, an FM radio, relay controls, audio amplifiers, oscillators and test equipment - are each designed with just two types of transistors. Building these transistor projects will be both fun and educational.
