mikeytown2··on An Introduction to Meshtastic
It's because we've tried Meshtastic and MeshCore. Look at where the bytes go in the network. Meshtastic it's usually under 5% of traffic is text and for MeshCore it's over 50%. If you want to communicate MeshCore is designed to do that.

He went off the rails as a reactionary move is how I see it. He got mad because his issue was deleted. I'm banned from the discord for a disagreement with one of the developers; but I've done code contributions to the project as well.
mikeytown2··on My First Meshtastic Network
Here's an example of an issue they didn't like getting deleted https://github.com/meshcore-dev/MeshCore/issues/1159

You can run a full blown weather station on MeshCore with wind rain temperatures etc

There's only so much bandwidth available so pick and choose what the firmware is good at. MeshCore went all in on messaging and tracing. Meshtastic is a more noisy protocol which is perfect for camping and hiking in small groups.

Both have GitHub projects that you can compile firmware from. One is MIT, the other is aggressively GPL
mikeytown2··on FreakWAN: A floor-routing WAN implementing a chat over bare-LoRa (no LoRaWAN)
You'd need two radios, one antenna stacked on top of each other. Z offset of a minimum height of 1m/3'. In the X,Y offset of 0,0. You want high gain 8-10db antennas in this arrangement; you'd need more space between if you use lower gain antennas.

If you're looking for parts the Diamond BC920 is the best antenna. Station G2 with a $100 3-4mhz cavity filter for each frequency as well.

Checkout MeshCore; we're doing 400 miles using 12 hops going from north Vancouver to Eugene Oregon https://analyzer.letsme.sh/map?lat=47.36113&long=-122.20419&...
mikeytown2··on Meshtastic 64 – A meshtastic radio for the Commodore 64
They're looking at ways to have regular nodes repeat on the network. Right now it's a one line change to enable it. Doing it well and smart is what's holding it back
mikeytown2··on Meshtastic 64 – A meshtastic radio for the Commodore 64
Checkout MeshCore, it has the concept of a room server which is a private store and forward server. Also see this https://github.com/mikecarper/meshfirmware/blob/main/MeshCor...

Check out the alternative https://github.com/meshcore-dev/MeshCore Seattle has the largest functioning mesh core installation in the world
mikeytown2··on Open Source is one person
Drupal isn't one person last time I checked; but yes this is correct for almost all projects
mikeytown2··on Burner Phone 101
Yes you can get decent reception inside buildings. It operates in the 915mhz band. Similar frequencies to old school pagers. Lora is an interesting RF protocol, it has really good properties for operating below the noise floor.

MeshCore has verified public key sharing; see what happened to the other network at defcon. Direct messages are encrypted.
mikeytown2··on Burner Phone 101
Range is line of sight. If you can see it, even if 100 miles away, odds are it'll work. Seattle area has one of the better networks for MeshCore. Tacoma to Vancouver BC is the range for semi reliable messaging
mikeytown2··on Burner Phone 101
It's mostly open source. https://github.com/meshcore-dev/MeshCore They have a couple minor things that are paid features.
mikeytown2··on Burner Phone 101
If you need to communicate with people in your area and not be tracked; MeshCore software with LoRa hardware like the this https://lilygo.cc/en-ca/products/t-lora-pager is something to consider. Text only, completely offline

Sound Cards with IDE ports for CD-ROM drives were definitely a thing back then

Use your phones slow motion video to check flicker. Phillips has one of the better led bulbs out there
mikeytown2··on EDAN: Towards Understanding Memory Parallelism and Latency Sensitivity in HPC [pdf]
EDAN gives you a fast, accurate snapshot of whether your program really benefits from faster memory or extra cache. You get clear signals on where latency matters and where it doesn’t using just one ordinary program run and a bit of smart analysis.
mikeytown2··on Ask HN: What are you working on? (May 2025)
Kids text only cell phone. LILYGO T-Deck Plus. I can track and communicate with them and not have to worry about giving them full internet.

Any sort of disaster they also are useful to get messages around. A couple days into a power outage and no cell towers work anymore, this happened 1 week before thanksgiving in the Seattle area 2024.

CLI Meshtastic flasher that works well. No internet mesh networking sounds awesome; just the bandwidth is extremely limited
