I have used CircuitPython in some projects, especially with my children. Python was easier for them than C. For small projects (domestic sensor, remote control car,…) there is no difference in performance. For those use cases that are more demanding and squeeze the possibilities of the SoC to the maximum, obviously, it is not worth it. Taking this into account, I think it is an alternative for many DIY projects that are being done out there

There are free IoT cloud solutions to send and receive data and that work with MQTT protocol for this purpose.

I find it very interesting and I want to do one with my kids. The guide is good from a step by step point of view about how to make one, but I think a couple of examples about what kind of data can someone get with it and what can someone expect to “view” could be very helpfull too

5G was only at example of new technologies. It is true that wireless internet need to be deployed in Africa and other areas, but Starlink need to be deployed in the space too. And in a short/medium term future will be easier upgrade earth based antennas than satellites in orbit. In the middle of the sea are satelital communications for important info actually, and this must be enough. See a film online in the middle of the Atlantic is not as important as the knowledge that the Galaxy give us (my personal and subjective opinion)

There are more options to get internet access, the new ones like 5G are wireless and with a huge bandwidth. Is really internet access in the middle of the nothing a priority? More than the potential knowledge about who we are and from where we come? I don’t believe in a World where people doesn’t know enjoy the nature and the wild places without internet.
