Saw IIT Spirit

I just watched this IIT video and I related to the person. https://www.youtube.com/watch?v=DmuVD0X-fEE

I remembered my time when I built a torch that could light in 3 different settings and I had it for display.

I don't specifically remember the details on how I got the box to hold all the components altogether but rather I vividly remember the 9V chargeable battery and the hold I had to make on the case to expose the button and the charging port.
How could I forget such a crucial instance of my life, it is why I am here.

Thank you life for this reminder .
