#meshtastic / #meshcore / #LoRa people near #boston: assemble. Get me connected to your non-corporate non-ham networking. I have nothing. What is the simple beginner portable setup I could buy in the US today, either pre-made or as a kit, that ships from the US? https://youtu.be/oAo2sb8LpFc?t=12 https://cambridgemesh.net

Friend gave me a #Meshtastic node (off grid mesh network over #LoRa radio).
Feeling #solarpunk af
It's quite active in my region, I've connected with approx 86 nodes!
The chatter on main is pretty standard. A bit of a prepper vibe and some gentle trolling of said prepper.
Would be cool to link up some of the radical houses here with Meshtastic nodes. The nodes are ridiculously cheap and portable (e.g. ESP32 and an antenna) afaik.
Meshtastic also requires encryption by default for non-default channels (aka main) which isn't allowed on amateur radio in the UK.
Would easily run off a power bank solar setup. I was running it off my phone for a while whilst connecting via serial over USB-C. Super low power requirements.

We walked 2km in the forest, uphill with a ladder and some tools in order to install this Seeed Solar Node on a dead tree.
I have a good signal from home - 12km throu forest and the coverage seems to be good too.
I'll let it be here over the winter month :)

This is what the Meshcore map looks like now in the Pacific Northwest. My little node can see over a hundred repeaters on the mesh.
We now regularly have chat conversations that span several cities and we have frequent posters from Canada. A typical day sees HUNDREDS of posts in the public channel. Whole sentences and thoughts, not just "ping".
Meshcore is really taking off!
A few weeks after the Mt Rainer feat, some friends went camping and hiking all around the Orcas islands and we never lost contact at all.
At times they had better connection to the mesh while camping than they do in the city.
They hiked up Mt Constitution and were able to get direct line of sight connections to repeaters in Seattle using a typical handheld LoRa radio with an external antenna.
Over this weekend I was sadly asleep for one of my favorite effects in radio, tropospheric ducting!
I'd read a paper years ago from a team who detected ducting events in 868MHz LoRaWAN networks. These events allow end devices to reach concentrator nodes hundreds of miles away, possibly even beyond the curve of the earth.
I was wondering if we'd see this in lora meshes and turns out YES!
There have been so many really cool developments in the last month just from adoption.
Recently someone hiked up Mt Rainer and had a conversation with us on the public meshcore chat. When I went through the cougar mountain repeater's logs I noticed my repeater in Seattle's U District was actually the first hop that was connecting them to the mesh.
If that wasn't wild enough, the hiker was using a TINY radio, the Seeed Studio t1000e 🤯

The scale of meshtastics avoidance of building security into the design is pretty epic.
It allows for the formation of an entire mesh just for MITMing it.
This ONE liner here in the PKI attack means that once a node gets poisoned the key we created is based on the MAC so -anyone- who knows your MAC can read your MITM'd traffic.
When attackers run mesh marauder against the DEFCON 33 firmware they are all working together. Anyone in range can read the MITM'd DMs.
https://github.com/datapartyjs/meshmarauder/blob/channel-chat/src/lorapipe-raw-packet.mjs#L191-L193
So when it's this easy to get a MITM going things like making posts in public chats as anyone you want feels kinda low key.
But I do hope that extended warranty works out, everyone seems pretty concerned about them.
The first new tool is lorapipe, a firmware that runs on most consumer LoRa radios.
We've tested it a ton on ESP32-S3 based Xiao Wio boards.
This turns your lora radio into extremely minimal serial device that sends and receives packets in a dirt simple CSV format.
The radio can be tuned on the fly to switch between meshcore, meshtastic and LoRaWAN sync words and frequencies.
I've been busy as hell this past week.
A lot of people have been asking hard questions about the security of LoRa systems when they hear about mesh radios.
I'm not one to trust the marketing so I and several friends put together two new LoRa tools to help us audit the security claims of LoRa mesh systems!

You can see the code and adapt it to your situation.
It assumes that you have some number of esp32-s3 meshcore devices plugged in over USB to a Linux based device which the Action's runner can access.
Shout if you have patches, improvements or questions!

Woot, just finished implementing my first GitHub / Forgejo Actions which allows me to programmatically push meshcore builds to my radios on the roof from the comfort of my browser.
It currently only supports deploying to esp32s3 based LoRa devices so far.
#meshcore #lora #radio #esp32 #cicd #meshcoredeployer #devops #forgejo
This is what a successful build will look like
This is my roof top development box. It has four esp32-s3 based Xiao Wio lora boards connected over USB to a raspberry pi.
The raspi is intrun powered by PoE
When deploying you'll be prompted to select a device to deploy to and configure the type of build needed.
MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging - CNX Software
｢ While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet ｣
Good news, there's an unreal amount of interest in meshcore lately.
My community came together and group purchased 20 nodes and have rapidly been onboaring tons of new LoRa curious hackers.
It looks like I might have single handedly increased the user base of the Seattle meshcore user base by 10 - 20%.

I’m going to Arctangent festival later this year and there is no cell signal so I’m taking these three Heltecs and giving two of them to close friends so I can find them at the festival!
I’m going to be running Meschore on all three (my experience of Meshtastic is it sucks all of the air out of the room and good luck sending a message to any of those contacts you found).
So if anyone else is going and wants to hop on the same mesh, this is your heads up!

The @atpfm folks have been singing the praises of these fairly cheap #LoRa sensors from YoLink. They don't seem to be sold in AU, is anyone aware of anything sold and supported locally (I'd prefer to avoid importing via Amazon if possible)? https://shop.yosmart.com/products/ys1603-4ys7903
