Meshtastic is an open-source project using low cost LoRa radios as a long range off-grid communication platform in areas without little or no communications infrastructure. It’s a portmanteau of Mesh and “fantastic”.
I found it shared on Facebook, which lead me to the subreddit post, which lead me to reading more about it and even finding Lemmy communities and local groups!

I also made sure to check if this wasn’t a hail corporate thing. And I also felt like I missed the era of homemade radios. So this is exciting for me!
You saw that post of the guy on the bus as well then?
I’m curious now. Can you share the link?

Yeah! It was on Facebook when I saw it though and led to the Reddit post.
