Wondering how to travel in time? Learn it with great Sir Stephen Hawking, according to whom time warp may be an option but seems pretty impractical, the reason being the feed back loop which will just oppose the feasibility of making a time machine and the concept using this theory. Are you intrigued by the […]

Transistor Relay Driver Circuit with Formula and Calculations
In this article we will comprehensively study a transistor relay driver circuit and learn how to design its configuration by calculating the parameters through formulas. Importance of Relay Relays are one of the most important components in electronic circuits. Especially in circuits where high power transfer or mains AC load switching is involved, relays play […]
How to Generate PWM Using IC 555 (2 Methods Explored)
The IC 555 is an extremely useful and versatile device which can be applied for configuring many useful circuits in the field of electronics. One very useful feature of this IC is its ability to generate PWM pulses which can be dimensioned or processed as per the needs of the application or the circuit. What’s […]
How to Replace a Transistor (BJT) with a MOSFET
In this post I have explained the method of correctly replacing a BJT with a MOSFET, without affecting the final outcome of the circuit. Introduction Until MOSFETs arrived in the field of electronics, transistors or BJTs to be precise ruled the power switching circuits and applications. Though even Bipolar Junction Transistors (BJTs) can not be […]
Astable Multivibrator Circuit Using NAND Gates
An astable multivibrator is referred to an electronic configuration which is able to generate continuous alternate high and low pulses from a couple of outputs, operating in tandem. Why IC 4093 You might have well come across such astable circuits using a couple of transistors, a couple of capacitors and a few resistors.However more simpler […]
High Current Voltage Doubler Circuit
In this post I have explained a voltage high current doubler circuit which will almost double the voltage that’s been applied at the input (up to 15V max), and also it becomes specifically useful since it allows higher current loads to be used at the output, in the order 10 amps. Since the voltage doubler […]
