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...
If you want to run your own script for example a shell script, python etc as a Linux service, please follow this guide. I have tested and already using this methods and this works perfectly. In this example i am using an Ubuntu Linux and a shell script (which will run ngrok as service) if you want to know more about ngrok check out there website.
STEP#1: Prepare you script file that you want to run as a service.
once you are done with editing save and exit
STEP#2: Prepare the service
Go to "/etc/systemd/system" and create a file with your naming preferences but should end with a ".service" for example my file name was ngrok.service
This how the file should look like. ExecStart is where you define the script that you want to run. Once you done editing save the file and follow the commands as follows.
To enable the service
systemctl enable ngrok.service
Reload the deamon
systemctl daemon-reload
Test the service
if you run "service ngrok start" it will start the service and you can type "service ngrok status" to check if the service is running or not and you can top the service by "service ngrok stop" command.
if it is running it will show as above image.
