In 2016, when I was 18 years old and still in dilemma about what the future holds for me, I stumbled upon a ted talk by Greg Gage (Founder of Backyard Brains) where he demonstrated the human-to-human interface.

I was blown away by this amazing experiment but didn’t have money to buy the kit so I researched more about it. The schematic of their biopotential amplifier was open source so I created a BOM file and started searching to procure parts from Chandi Chowk, Delhi. It took a lot of time and an entire month’s pocket money to get all the parts.

Finally, I assembled everything on a perf board as you can see in the images below.

I was very excited and hopeful but unfortunately, it didn't work out!! 

I still don’t know if the wiring was faulty or the components but one thing is for sure, I didn't give up.
