The project is about the size of a standard AA battery which aims to build a single transistor FM transmitter. Having a power supply of 1.5V cell is the main advantage of this circuit. The battery is ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, it’ll take a couple ...

On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...
