I was going through my list of unfinished projects, and decided I would set up again a Meshtastic node. I first set one up a couple of year ago I think but didn’t really see much activity. This time around, there are a lot more nodes!

In simple terms, Meshtastic allows for text messaging between devices that is not reliant on the cellular (mobile) network or the Internet. As it is a mesh network, the data passes between each device (node) rather than a central point, so more devices there are, essentially the better the spread of the network. It sends the data over radio and it’s designed to use as little power as possible.

I flashed my Heltec v3 with the Meshtastic firmware (Kinda bonkers that such a low-level thing can be done through a web browser!), then set it up in my roof space. It’s currently using only the stubby antenna it comes with, has no casing around the PCB, and is plugged in via a USB-C to USB-A cable hooked up to a USB power adapter. Now that I have seen there is much more activity, the next steps will be to 3D print a case for it and to properly mount a better antenna that I already have. Hopefully running this will mean that I can use in my local area the portable units that I have and the signal will be better propagated through the node I’m now running at home.
