Arnab Kumar Das (Crazy Engineer)

Hey! this is Arnab Kumar Das, you can also call me the Crazy Engineer. By birth I am an Indian, by profession, an Electronics and Communication Engineer; other than that, I am a free soul who loves to explore the world and various cuisines and make weird funky gizmos. Apart from that I also love clicking pictures, because I feel they are a tangible form of memories.

Electronic appliances have always amazed me. As a kid, I used to open up every gadget that could possibly be dissected. I was 14 when I first had a taste of ‘successful solo creation’, a CLAP Switch — a switch that works with ‘clap’ sounds!! that was the beginning, the zeal increased with time.

While pursuing my bachelor’s degree with Electronics and Communications major, from Lovely Professional University, India, I had the opportunity to explore more. It was during this period when I started capturing the process and hustle of making my projects. Gradually I compiled these clips into properly organized and edited videos, which you can find at Arnab Das YouTube channel.

Being from the land of Upanishads and Vedas, I believe knowledge is that superior wealth that no thief can steal and when shared it keeps on increasing; and this is the sole reason behind these blogs and my YouTube channel. I want to share whatever knowledge I have gained to date. I would love to share not only my successful projects but also the hardships I faced during the journey. Hope you would walk with me too.
