Custom ESP32-S3 development board — professionally manufactured by JLCPCB. A far cry from where it all started. It Started in a School Science Lab — Around 1998 Most people who get into electronics start with a kit, a tutorial, maybe a breadboard and some LEDs. I started by sneaking ferric chloride out of a school science lab to etch my first PCB. That was around 1998. I was living in the Maldives — a small island nation in the Indian Ocean — where there was no electronics supply chain, no maker community, no local PCB fab. Just a chemistry cabinet at school, a copper-clad board from somewhere, and a lot of curiosity. This post is about what the next 25+ years of PCB prototyping looked like from there. The early wins with proper chemicals, the years of improvisation when those chemicals disappeared, the real injuries, the failed boards, and finally — the moment JLCPCB changed ever...
Last week i was too busy with office projects and i did not have any time for my micro controllers..But now i am free from office work so i continued my projects.
I am designing a small circuit to operate a stepper motor and the circuit will detect the rotation/minute to get the RPM and send to PC. So from hyper terminal you will able to see the RPM. I am planning to get the direction it move. Soon i will upload some more description of it.
