If you want to be pinged with a reminder asking about your project, let me know, and I'll harass you each week until you cancel the service.

I recently bought a Meshtastic board, a Heltec v3. For those who aren't familiar, this is a license-free low-bandwidth LoRA (long range-radio) device that can reach out very long distances on minimal power. The Meshtastic platform is a peer-to-peer network that supports text and data communication, the most notable part being that each device on the network is a node that receives and re-transmits messages to other nodes around them. In areas with good coverage, it means that you can potentially send messages to someone several hundred miles away from a board the size of a pack of gum.

I'm in a metropolitan area but at the base of a hill and don't have a very good connection to the rest of the nodes in my area. If I had the space, I would make a solar node (enclosure, solar panel, charge controller, battery, Meshtastic board, and antenna) and mount it on the roof, but unfortunately I live in an apartment and can't quite do that. However, if I find a good spot in the future, I might perform a guerilla installation somewhere nearby. Ideally it would be somewhere I frequent, since I would need Wifi or Bluetooth to connect to the node with my phone.

You can find a Meshtastic kit on Aliexpress for maybe $35 shipped, I would highly encourage anyone with even a passing interest in radio to pick one up and play around with it for a weekend.

Very nice!

I've idly wondered before how hard something like Meshtastic would be, so this has definitely got me interested.

How did you choose the Heltec v3 over the many other options?

Are "guerilla installations" common in the Meshtastic community?

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
