A Practical Introduction to Transistors Basically the function of a transistor is to amplify a small 'base/emitter' voltage into a much larger 'collector/emitter' voltage. A simple experiment will explain how does a transistor work.
2N3055 Transistor Datasheet Explored Almost 90 % of all medium power electronic gadgets incorporate 2N3055 transistors in their output stages – probably enough to prove the high versatility of the device. The article provides you with all the necessary details about this important electronic active component.
DIY: How to Build a Hand Crank Flashlight A hand operated flashlight does not need input from sources like wind or sun in order to generate electricity. Just pressing a spring-gear mechanism is enough to make the device “pump” electricity that can be used for activating an output load.
Generating Electricity from a Bicycle Dynamo The proposed mini-electricity generator project is very simple to build and can be used by students as a school project, or just for hobbyists. The set up can be used to charge a battery with electricity produced from wind power.
Making a Homemade Power Amplifier - PCB Layout Included With monolithic linear ICs becoming commonly available, making monster power audio equipment at home has today become a child’s play. One such device STK4221 from SANYO can be simply used for different massive power audio amplifier applications. One sample circuit is discussed herein.
Simple Thyristor Circuits Explained The article relates the technical specifications of SCRs and their working principles through an easy to understand, step-wise explanation. The article also offers a few interesting SCR projects that can be easily built and used for the relevant purposes.
