I, Arnab Kumar Das aka. Crazy Engineer, Am an Electronics and Communication Engineer, I love to travel, eat good food and Make Crazy Gizmos. I was born and brought up in Incredible India. I have had a keen interest in electronics and gadgets since I was a young boy and have had many amazing mentors throughout my journey. As a kid I used to open up every appliance I found. I learned electrical circuits and appliances from my father. I got my first solder iron at the age of 13 and after that I started making DIY circuits. My first notable project at the age of 14 was “CLAP SWITCH” that switches on and off any appliances by a clap sound. And my craziness continued……

While obtaining my B. Tech (Hons) degree from Lovely Professional University, Punjab, India, I started making YouTube videos, which opened a door I never dreamed of.

I have put up videos of different projects that I completed during my engineering degree and am now planning Tutorial and other Crazy DIY guides. I love sharing knowledge and I think YouTube and this Blog are one of the best ways to share my knowledge. My friends call me The Crazy Engineer because they see my passion for technology and electronics.

I also have participated at numerous Tech Fests and competitions including national as well as international events. I have experience in Analog electronics, Embedded Electronics and also Mechanical Project like Go-Kart and E-Bike designing.

I can’t live without my tools and hardware. I am obsessed with well-decorated and well-lit spaces. In my free time I love doing Photography also I love warm weather, technology and friends. I Dream of being an inventor and doing something good for the world.

As I keep exploring the new directions technology is taking me, I truly hope you will follow my journey and be a part of it!
