WiFi - A few months back my cousin came for a short visit. The first thing she asked was "what's the name of your network and password please", apart from the preliminary pleasantries, of course.
We were online 24/7, Internet access is a fundamental part of our modern daily life, as running water and electricity. I still remember when I was small, in a short period of my younger days where there was no running water or electricity in our shack of a house.
If we can see the radio waves we will see a rainbow of colors. If we can hear WiFi we will hear a symphony of music. Or maybe cacophonic of sounds and hellish pulsating neon colors.
Enough dreaming.
The good thing about esp32 ( or esp8266) is that we get a WiFi ready computing chip with a price of ... peanuts. What more, it can serve as a WiFi access point and/or a WiFi station. With limited range and duration, it can operate on 9V battery.
I'm experimenting with an esp32-cam running on fully charged 9V 400mAh. The esp32-cam will operate as a WiFi access point, run a video streaming web server. I am interested in how long it will run continuously serving live images to an android phone.

Initial results so far. The live stream looks nice, smooth and crisp. One hour has passed since I started. I'll let you know for how long the power will last.
By the way, thanks for coming by. I got friends out there. You might be inspired to start with micropython and esp32/esp8266 programming. Perhaps, you will even begin writing blog posts.
My GitHub is now updated. You can find the compiled firmware there.
Talking about limited resources, micropython is designed to operate in constrained environments, needs a minimum of 256k of code space and 16k of RAM to run.
