I may have sent the most over engineered text message in history...

This vid touches on something that Reticulum does that no other networking stack that I know of can - bridge normal internet to off grid radios like LoRa.

And with the tooling improving by the day, client apps like Columba abstract away all the details leaving you with, what feels like any other messaging app. That’s the part I care about most: the person using it shouldn’t need to be a radio expert—or even know which link carried the message. All that complexity should live with builders like us, not with the person who just needs the message to arrive. This is the beauty of Reticulum.

In this video I tap into that and other recent developments like Heltec V4 RTNode firmware that runs the entire RNS stack on a higher tx enabled MCU like the Heltec v4 which kicks out 27dbm, now enabling new stand-alone infra options like solar nodes, or drone relays (like what I end up using in the video). Something meshtastic has been able to do for a while now Reticulum does as well.

And that process is easy as pie using a web flasher like this one.

I then modded Meshchat (see CrossTalk) to do a better job showing transport nodes that don't have LXMF delivery addresses. CrossTalk is my experimental MeshChat fork, not a client I’m trying to push. It just lets me add features on the fly—like exposing the transport nodes carrying these messages.

Last but not least, these rigs are about as inexpensive as it gets which lowers barrier to entry for anyone trying to get involved.

The route in the video was deliberately absurd, but the core building blocks are there and I don't see this movement slowing down any time soon.

Running Morse Micro’s MM8108 HaLow card on a Raspberry Pi 5 with OpenWRT

I got the Morse Micro MM8108 HaLow card running on a Raspberry Pi 5 with OpenWRT.

This is the newer MM8108 chip, not the older MM6108, and the build is running on the Pi 5 instead of the Pi 4. The goal was to turn the Pi 5 into a long-range HaLow mesh/router platform using OpenWRT.

The MM8108 matters because it is Morse Micro’s newer HaLow radio path: better range/throughput potential, better transmit efficiency, and lower power draw compared to the previous generation. So the upgrade is not just “Pi 5 support” — it is a stronger compute platform plus a newer sub-GHz radio.

I also upgraded the battery system. Haven 1 used two 21700 cells, around 10,000 mAh total. This build uses a Waveshare battery HAT with four Molicel 21700 cells, around 18,000 mAh total. The Pi 5 is hungrier than the Pi 4, so the extra battery capacity and cleaner power path actually matter here.

The setup is:

- Raspberry Pi 5

- Morse Micro MM8108 HaLow card

- OpenWRT

- long-range 802.11ah / HaLow link

- normal Wi-Fi for phones, laptops, cameras, etc.

- upgraded 4-cell 21700 battery system

I published the build here:

https://github.com/buildwithparallel/openwrt-morse-rpi5

You can either download the prebuilt image from the repo, or build it yourself from source if you want to inspect, modify, or reproduce the OpenWRT/Morse changes.

This is still early, so expect rough edges, but it boots and the card works.

This is part of the Haven 2 build: Raspberry Pi 5 + MM8108 HaLow + OpenWRT.
