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...

| Blank ATmega328 flushed with Arduino boot loader |

| Flushed ATmega circuit built and testing with sketches (This board is named as "pixelduino") :-) |
My recent test with Arduino is flushing an ATmega328 with arduino boot loader and its successful. I have an Arduino UNO SMD version and its loaded Arduino ISP sketch, to make it as an ISP programmer.

| Arduino UNO connected to Blank ATmega328 as an ISP programmer. After flushing its loaded with blink sketch for test and it works well. |
So now i can avoid the Arduino board in some of my final projects.
