If you're interested in that sort of thing but don't want to bother with the hardware then you should check out the reticulum network. It's pretty neat. It's basically like meshtastic, only it doesn't just use LoRa frequencies. It can use LoRa frequencies, but it can also use other radio frequencies, or Bluetooth, Wi-Fi, Ethernet, or whatever really. So you can just access it using your Wi-Fi, no hardware needed right away. But because it can work with whatever medium you like can create a mesh network at a global scale, rather than just connecting with people in your area. I think the long term goal is to create a new, second internet that is more private and more resilient to disaster scenarios or state censorship. It's pretty neat.

You can use it to browse pages on the 'NomadNet' which is basically like what the internet was like in the late 80s. You can browse through your terminal, though there is a graphical interface for it called MeshChatX, though I've never really used it (the terminal works fine imo, but it's not everyone's cup of tea). There's a community for it here on Lemmy, though it's not very active. !Reticulum@mander.xyz
