Freak Engineer – Akash Sharma

This site contain tutorials of electronic projects, basic electronics and Digital electronics. I also post video tutorials on my YouTube channel named freak engineer.

You can see a glimpse of my work on a short video of my Channel Trailer.

Tesla coil Project

Tesla coil was invented by scientist Nikola tesla. The high frequency electromagnetic waves around the tesla coil can easily excite the gas present inside fluorescent lamp and neon bulbs.

0 to 9 counter using arduino nano

0 – 9  counter

In this tutorial, we are going to make a 0 – 9 counter using Arduino nano and a 7 segment display. The display will count the numbers from 0 – 9 in a loop mode.

220 V LDR Circuit

This article is a tutorial for LDR circuit. Basically we are going to make a circuit that automatically switches on whenever it senses darkness ( no light particles ).

RF Transmitter & Receiver Circuit

This article, I will show you the basic application of RF module by transmitting and receiving 4 bit data to control LED’s wirelessly.

VU Meter using LM3915

In this article I am going to discuss about vu meter circuit using lm 3915 IC. A VU meter can be described as an audio visualizer circuit.

Binary to Grey Code

In this article we will cover Grey Code, BCD to Grey Code conversion and Grey code to binary conversion. Its application, advantages and  disadvantages.

Half Adder and Full Adder

Half adder and full adder is a part of combinational circuits. Combinational circuits are those whose output characteristics depends on their input levels at a particular time.

Piano Circuit Using 555 IC

A musical instrument with multiple keys that creates different tones when pressed is known as Piano. In this  article you will learn to make your own electronic piano circuit .

Quine Mccluskey Method

In this article we will cover Quine McCluskey method with examples. I will show you the simplification of Boolean expression by Quine Mccluskey method.

Transformerless Power Supply

A transformer-less power supply is a circuit that converts AC input ( 230 v ) to low voltage DC at low current, without using a transformer.

Full Adder Using 1:8 DEMUX

In this article I will show you how can you implement full adder in 1:8 Demultiplexer.
