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 […]
How to Make a Dual Tone Siren Circuit
This two tone siren circuit explained here gives out a continuously varying high amplitude sound. Since the supply voltage is not critical, it can be used in cars, motor cycles or at home. It can replace the ordinary call bell. A dual one siren is an amplified alarm circuit designed to generate two different audio tones resembling […]
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 […]
