>>2858228
...why?

>>2858259
Because no cell signal, it's basically like using walkie talkies except texting and nobody else can listen

>>2858286
You don't have a fucking clue what you're talking about. Just buy a gmrs radio.

Are you a woman?

>>2858286
just use smoke signals

>>2858286
That... isn't correct, no.

No I do not but I have done some theory crafting work on how LoRa could be used effectively in a collapse and rebuild scenario by a small group hidden in the mountains.

So using SX1262 transceivers, arduinos and pi's, 3.7v lithium batteries, 2w-10w micro solar and various other sensor modules you can do a lot and your static modules can be hidden. It's quite powerful technology. The group would set up a base station with a tx connected to a larger pi with a screen that collects and logs all of the information sent by the smaller modules. The smaller static modules would be a microcontroller, sensor module, battery and solar panel connected together providing data such as temperature and moisture data coming out of a microgarden the group would cultivate. This data would be used to optimise what to grow in each garden. You can connect any low wattage sensor module to these little static remote systems so could also be used with passive infrared to detect movement as well as vibration sensor under the ground to detect steps and so on and so forth. It's such low power that your imagination really is the limit of what you can do with it.

>>2858305
I'm just going to call you a retard and not elaborate

>>2858322
It's a great idea its going in my book.

>>2858322
You're out of your depth donny

>>2858305
you just reinvented meshstatic but anyway in a collapse scenario you won't find a fuck raspberry pi, it's already hard to get nowadays

>>2858356
I have 20 pis.

>>2858286
Me and my friends have looked into this. Plain old radio is better for most applications. Look into APRS, it's radio but can send text and use "digipeters" to send it to the far side of the globe or even to a cell phone. Compared to radio, meshtastic has less ability to penetrate so it will be blocked by foliage easier. If you're on the peak of one mountain and your friend is on the peak of another mountain so that you have line of sight, you can communicate. But this is in a situation where your phone has charge but no reception. There aren't any good standalone meshtastic devices last I checked. The T deck is the closest I've seen and most people complain that the firmware sucks dick. The only real pro that meshtastic has over radio is that you aren't allowed to encrypt your radio comms while the ISM band that meshtastic is on has no such restriction.

>>2858377
I've looked at this (nta I'm a Taiwan anon prepping for war)
>need a license
>radio will 100% be jammed
>200 dolarinos
>Encryption is illegal (even with licence)
>repeaters need a lot of power
Seems like meshstatic wins for my scenario

>>2858305
No. I just- no.

>>2858380
Valid points although there is no reason that meshtastic can't be jammed as well. It's a narrower band to jam. And it seems to me that if you're going to war then having a license and obeying encryption laws are both moot points.

>>2858373
What do you use them for?

>>2858406
I bought them years ago with about 20 arduinos and hats for the pis and have used them for many different projects. They are older pi 3 model b's and zero's. I experimented with wing flight controllers. Homemade missile systems with pi brains to make them IR seeking. CCTV systems using runcams. A home server.

Most of them are just sitting in a box now.

>>2858385
Yes, yes yes yes.

>>2858228
I have tried them with Scouts, but the problem is you have to be somewhat a radio nerd to keep them working. I can set them up but if they quit I need to be the one to troubleshoot, and I need to be the one to charge them, etc. We did have some success using them for adults to communicate at a summer camp but that was stationary and near the cars. It reminds me of 3d printing from 8 years ago. Great for a hobbyist who can tinker but not production ready for people who want something that just works. I really want it to mature tho because it will provide capabilities that don't exist yet.

>>2858401
It's narrower yes, but basically nobody uses LoRa in a military context. In case of an attack the chinks will probably jam common radios VHF/UHF freqs which will probably affect APRS but not LoRa. I'm not an expert I'm not sure I'm correct tho

>>2858454
None of that made any sense. Pis make for poor flight controllers, ir seeking would require very expensive thermal equipment, and would require much faster processing than a raspberry pi. Also runcam is an fpv hardware company, not a software for cctv and has nothing to do with raspberry pi

I’m an idiot for even replying to your nonsense

>>2858228
Yeah I do, it doesn't work. Power output is 0.1W
Meshtastic is more about being radio enthusiast that for actual communication.
Just get two radios, if you don't want to dive too deep into it get something consumer friendly like Xiaomi radios, those can pair to phones and share map positions where there's no network.

>>2858476
Mock me all you want, but I've already got my homestead running nearly autonomously with a 4 pi array monitoring and feeding all my animals, and I've got a pi powered ball drone that analyzes and makes crypto trades for me faster than any human could

I have been using them for a bit now, here's my takes:
General
You will probably want the RAK based boards, much better power consumption. I don't find the LCD screen necessary, any diagnostics, flashing, etc. can be done via USB-C or bluetooth. We found that 2000mAh batteries is sufficient for several days as long as you aren't texting up a storm.

LongFast is the default channel, I would suggest coming up with your own channel set up on ShortTurbo or similar. Unless you are covering large distances we didn't find significant issues but the increased bandwidth is great. Also make sure it has the GPS antenna and set up reporting for that.

Map settings are good to drop way points. You can set it so they are never forgotten and then just wipe them when you are done.

Pros:
Brainless to run once they are set up. You can't talk over each other. You can just shared waypoints on the map and such. You can literally just hand it to Bob, pair his phone, you're up and running.
Extremely small and power efficient, turn them on and leave them on. Good for finding a buddy because it's transmitting GPS even if he's not talking.
Repeaters are inexpensive comparatively to radio repeaters due to full digital mode. Put a board in a water proof case with a big battery and leave it at camp or bolted to a car roof rack. A HAM repeater comparatively will be a couple hundred depending on what you have and consume a lot more power.
Less expensive than a decent digital mode radio with APRS, ergo cheaper to have enough for everyone.
Small as fuck.

Cons:
Still need a phone unless you are using something like the T deck with built in keyboard or some other custom set up. Phone is another thing to charge.
Even if you print your own you are probably looking at 90-100 bucks per RAK based mobile unit. ESP32 boards can be used but the eat power faster. They are better for hardwired power applications.
As slow as text messaging is, depending on your real time needs that could be an issue.

>>2858610
The end solution is that we usually end up using both mesh nodes and standard VHF/UHF radios. Coverage with the nodes when you have a bunch of them can end up better and you can have very frequent GPS updates with very little power. But with smaller numbers you can usually keep track of each other and not wander out of radio range. So pick the use case that works for you and roll with it. At a certain point it might just require trying it out.

At home I have a little ESP32 device plugged in on the desk and set up to the public LongFast channel, just a nerdy chat room really. In Philly there's like 500ish nodes with 100 visible at a time and I don't have the antenna in a particularly good spot. I do plan to build several others for Home Assistant purposes, mostly temp and humidity monitoring at the onset so I can tell if say my freezer loses power or the basement is flooding. I think I could probably use a CMOS sensor equipped one to do rudimentary motion detection.

>>2858305
>>2858475
You can also use 900MHz antennas to detect commercial wireless drones. But yeah this frequency is 100% getting jammed anyway if drones are in use. That is why Ukraine is covered in fiber optic cable.

>>2858474
For a static location like that yeah better off with a one time investment of a decent repeater in a box, GMRS license, and just a stack of radios. The real time map is kind of neat but only if you have a use for it.

>>2858476
It worked better than a $500 myflydream controller. Yes you are an idiot who cannot afford 20 pis.

>>2858618
>But yeah this frequency is 100% getting jammed anyway if drones are in use. That is why Ukraine is covered in fiber optic cable.
They would have to hike into the mountains to jam it. And jammers dont work over the horizon.

>>2858606
No you don’t, take a picture. Seriously. That sounds awesome but you’re just larping.
>>2858636
I am too poor to afford 20 pi’s sitting in a box unused. My pi’s are setup as cameras using mediamtx. I want to build an ups for them so they still function if the power goes out, but I don’t really need that.

>>2858385
Great argument, faggot.

There's a population here that is so afraid of any long term survival

>>2858649
Explain?
Explain how lora fits into long term survival. Explain how you can acquire and maintain this hardware in a SHTF scenario


You can’t and won’t.

>>2858652
Define long term survival. Clearly some people have stock piled certain electronic goods.

Why are you so aggressive? I come here to unwind but you are like a wind up toy taken past max.

>>2858228
just get a baofeng radio program it with GMRS and use it at full power. it also has scrambling.

>>2858652

LOL, there is no way you would ever get a signal unless you were "camping" in your back yard in the suburbs
