This seems like a great technology to build resiliency and redundancy in a community, especially for places where cell service is spotty, or in the odd event where normal lines of communication are blocked.

The LoRa boards can be easily powered with a small solar panel for continuous use, and if put in a high enough place with a good antenna, they can have a surprisingly long range!

In addition to being genuinely useful, they also seem like they'd be a lot of fun to experiment and play around with, printing cool 3D cases for them, or designing a better antenna or repeater setup.

If and of you already have experience with LoRa, I'd be interested to hear your thoughts! :D

I have some experience with it but I am by no means a radio expert or ham radio buff.

If anybody is interested in setting up a node, I'd highly recommend the wisblock/rak4630. They're very low power and easy to power indefinitely with solar. It can seem daunting at first but it's actually pretty straightforward once you do a little reading online.

You just need the wisblock, an 18650 battery, and a solar panel along with JST 1.5mm and 2.0mm connectors to hook them up and it'll start working.

Here's a zine if you wanna diy it. https://github.com/iffybooks/3.3v-solar-power-station

There are also more plug and play options out there too.
