How to Understand IC 4017 Pinouts

Last Updated on June 7, 2026 by Swagatam 246 Comments

The IC 4017 can be considered as one of the most useful and versatile chip having numerous electronic circuit applications. About IC 4017 Technically it is called the Johnsons 10 stage decade counter divider. The name suggest two things, it’s something to do with number 10 and counting/dividing. The number 10 is connected with the […]

Light Emitting Diodes (LED) Explained

Last Updated on June 7, 2026 by Swagatam Leave a Comment

LED structures

The full form of LED is Light Emitting Diode. LEDs are special type of semiconductor diodes which emit light in response to a potential difference applied across their terminals, hence the name light emitting diode. Just like a normal diode LEDs also have two terminals with polarity, namely anode and cathode. To illuminate an LED […]

How to Connect Two or More Transistors in Parallel

Last Updated on June 3, 2026 by Swagatam 63 Comments

parallel

Connecting transistors in parallel is a process in which the identical pinouts of two or more transistors are connected together in a circuit in order to multiply the power handling capacity of the combined parallel transistor set. In this post I have explained how to safely connect multiple transistors in parallel, these can be BJTs […]

Making a Time Machine – Concept Explored

Last Updated on May 20, 2026 by Swagatam 3 Comments

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 […]

Calculate Battery, Transformer, MOSFET in Inverter

Last Updated on May 20, 2026 by Swagatam 105 Comments

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 […]

High Current Voltage Doubler Circuit

Last Updated on May 20, 2026 by Swagatam 18 Comments

highcurrentvoltagedoublercircuit

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 […]
