In this post I will comprehensively explain how to protect mosfets and prevent mosfet burning in electronic circuits by following some basic guidelines related to correct PCB layout, and careful manual handling of these sensitive devices. Introduction Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within […]
Newly Updated Circuit Projects:
IC 7805 Variable Power Supply Circuit [5V to 15V]
Although, a 7805 IC is mostly used as a fixed 5 V voltage regulator, it is possible to configure a 7805 IC to produce a variable output from 5 V and higher, depending up the input DC supply. In this post I have explained a simple circuit network which can be used for getting an […]
Digital Step Sine wave Generator Circuit
In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]
Sine wave PWM (SPWM) Circuit using Opamp
SPWM refers to Sine Wave Pulse Width Modulation which is a pulse width arrangement in which the pulses are narrower at the start, which gradually get broader at the middle, and then narrower again of the end of the arrangement. This set of pulses when implemented in an inductive application like inverter enables the output […]
Police/Ambulance Siren Circuit with Rotating Beacon Light
In this post I have explained how to construct a police, ambulance or a fire truck siren circuit using evergreen IC 555 timer and we will also learn how to build a revolving beacon light without any mechanical parts. The proposed project is divided into two parts the siren circuit and the rotating beacon light, […]
Firecracker Igniter circuit [Remote Controlled with Timer]
In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter circuit designs using ordinary components which we will be exploring them in detail. Before we jump in to the circuit details, we have a word […]
