In this section I will share the devices and other interesting stuffs we have made in the various labs I have worked in, through the course of my journey from someone without a clue of how experiments are done to someone who knows a bit of it. The more I know, the more I appreciate the efforts that go in making the tiny things, some curiosity driven and some driven by exreme smartness to access intricate physics!
