Simple Bird Sound Generator Circuit
The diagram presented below shows a simple circuit of a bird chirping sound generator. All the parts are very common and the transformer is an ordinary type as found in small transistor radios at the output stage Circuit Operation The circuit is basically a feedback oscillator circuit that is configured around a small output transformer. The transistor forms the […]
Make this Simple Buzzer Circuit with Transistor and Piezo
In this article I have explained how to make a very simple circuit for buzzer using piezo electric transducer, two resistors, a small coil and a BC547 transistor. A buzzer is a high frequency oscillator circuit used for generating a buzzing sound through a transducer or speaker output. Simple Buzzer using a Single Transistor Just […]
2 watt Amplifier Circuit
A very simple 2 watt audio amplifier circuit has been presented here which can be constructed by all new electronic hobbyists for amplifying small signal frequencies and for other similar experiments. Circuit Operation
Amplifier Short/Overload Protection Circuit – 2 Ideas Discussed
Due to some reason if the loudspeaker of a power amplifier gets shorted, that may lead to a fatal damage to the amplifier component. To prevent this an amplifier short circuit protector circuit can be very useful. In the following post I have explained 2 simple amplifier short circuit or overload protection circuits for safeguarding […]
DIY 100 Watt MOSFET Amplifier Circuit with PCB
MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easily beat the performance of other counterparts based on power transistors or linear ICs. Why use MOSFETs in Amplifiers Amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection […]
