Charging a Small NiMh Battery from Air
In this post we will try to investigate a circuit which can charge a small Ni-Mh battery by extracting free energy from the ether or air. I have explained more Discussing how to Derive Free 9V from Air – By Steven Chiverton Mr. Steven has devised an ingenious way of collecting energy from the air […]
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 […]
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 […]
How an Inverter Functions, How to Repair Inverters – General Tips
In this post we will try to learn how to diagnose and repair an inverter, by comprehensively learning the various stages of an inverter, and how a basic inverter functions. Before I have explained how to repair an inverter it would be important for you to first get fully informed regarding the basic functioning of […]
Calculate Battery, Transformer, MOSFET in Inverter
In this post I have explained how to correctly calculate inverter parameters with associated stages such as battery and transformer, by calculating the matching the parameters correctly. Introduction Making an inverter all by yourself can be definitely lot of fun. However if the results are not satisfactory can completely spoil the whole purpose of the […]
