Was going through my old electronics stuff back home and found this beauty. Probably the first PCB design which got made when I was a student with a friend of mine. Should be at least 12-13 years old. Locally etched, single layer.
It was for a line follower robot competition. 5 IR LED pairs and an L293D DC motor driver IC. I believe we got it working fine without any external help. These were the days before 2-day PCB delivery services, full-fledged electronic blogs, YouTube video tutorials, eCommerce component websites or heck even before proper broadband connectivity at home. 1GB per month data plan for the whole family with a blistering speed of 256KBps. Oh, those were the days…
It was super hard to do electronics in India during those times (And probably still is…)
