In this article we investigate a free energy device concept in the form of a gravity LED lamp circuit for illuminating an LED through force of gravity. The Circuit Concept Gravitational force is an awesome source of energy, amply available on this planet, and easily accessible, however, nobody yet has been able to convert this […]

PWM Inverter Using IC TL494 Circuit
A very simple yet highly sophisticated modified sine wave inverter circuit is presented in the following post. The use of the PWM IC TL494 not only makes the design extremely economical with its parts count but also highly efficient and accurate. Audio/Video Representation Using TL494 for the Design The IC TL494 is a specialized PWM […]
Making a Time Machine – Concept Explored
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 […]
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 […]
How to Use an Op amp as a Comparator Circuit
In this post I will comprehensively explain how to use any opamp as a comparator in a circuit for comparing a input differentials and producing the corresponding outputs. What is an Op amp Comparator We’ve been using an op amp IC probably since we started learning electronics, I am referring to this wonderful little IC […]
