So I’ve been experimenting with LoRa and meshtastic.

@jwildeboer if it helps, I pressed the button on the bits for a T-Deck based on your posts.
I've got some older LoRa modules I'm going to try and make work with the newer hardware. I'm also pondering putting something on a M.2 PCB and making it all internal in my ThinkPad...

@hughsie Hahaha! The mesh is spreading Have fun!

And the new antenna on my balcony node has made it possible that I could send a message successfully from my orange node with its little antenna to the T-Deck at home (also just a little antenna) by using it as a hop in the mesh. That’s 900m in a densely built part of Munich with a measly 22 dBm transmission power. Nice!

@jwildeboer what does your balcony setup look like? Any special antenna? I can’t get more than 30 feet with an antenna in my setup. (I’m US frequency, also using the heltec based board.)

@codingpanic I got this 16€ antenna which promises a 8 dBi gain, directly connected to the Heltec V3. And it seems to work. I’m no expert, didn’t measure the output

And before I go to bed, I finished upgrading the balcony node from a 2000 mAh battery to the 10000 mAh version in the big case. It came with 77% charge, so should survive the night. The node is outside on my balcony, connected to the 6W solar panel. I’ll be travelling for a few days, so it’ll be interesting to see if it stays online while I’m away.

@jwildeboer How would you go about such a bigger run? Curious for some of my own 3d printed and custom electronics ideas I've had.

@elight I wouldn't I'd happily do a run of 25-50 devices for friends and followers who know what they are getting into, but that'll be the max. If I would do that, I'd get the orders in (prepaid, no discussion, trust me or not), source the components needed (+5% to have some wiggle room for defective stuff) and spend a weekend on putting stuff together and shipping it.

@jwildeboer That's pretty much its main use case. Look at the cobra hood of a modern LED streetlamp. They're LoRA nodes with a mix of (mainly air quality) sensors.

@sbisson But typically LoRaWAN, which is quite, but not completely open. Meshtastic replaces (AFAICS) the WAN part of the stack with a more open solution.

@jwildeboer Hello, I am interested in your experience. Do you plan to document it?

@barochat This whole thread is part of that, yes I will put in a short blog series sometime soon, promised

@jwildeboer so why not use regular FSK at low bandwidth instead so it can interoperate with more stuff?
-
@feyter
Why not using both?
Globally with one system (e.g. Smartphone), and (hyper)locally via such a mesh?I wonder, how much of a "nerd"* one has to be, to get into this topic!
*) not at all meant negatively!

@f4grx because right now I’m invested in meshtastic, which already has quite a lot of support and is GPLv3 licensed. I might look at other solutions later too, but my bandwidth is limited

@jwildeboer Is it waterproof though?

@pixelcode No. but it looks good (on my balcony it is inside of a weatherproof box)

I plan to get into this as soon as I have a few hun to spare. I am uneasy about the radically open nature of it, particularly since the nazi demographic are also very into this stuff, but it seems to me that it's an incredible tool for community resilience in moments of physical crisis (power outage, loss of communications networks, etc)
