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...
Now technology is going from micro to nano and beyond. Department of Energy’s Sandia National Laboratories- Have developed a Lilliputian "machines" operating inside living cells. A robot which is smaller than a dime. It was so amazing..i got the video from there website.
This little fella have a an 8K memory processor as its brain and almost all type of sensors, gas sensors, a cam, microphone and collision detection. I think you guys will love this. I will give the links and you can see more info.
