I learned more about this subject in the first 5 minutes of your video, than all the countless other video's I have watched, from other channels combined. Great video, thank you.
These nodes are becoming so popular it’s crazy. Used to be able to get them in 2 days but now it’s more like a month. I have 6 heltec, 2 T beams, and a T Echo with 4 more heltecs and 2 more T Beams on the way. I’ve been setting them up all over town here in Jeff City MO. I like your post this morning about being supportive of the new guys in the group so I’m spending my morning watching your videos.
I have 5 of them and have played with them. Pretty cool. I picked up a couple 10w solar panels and plan on putting 3 of them in a weatherproof box and use an antenna extension cable and use them as repeaters in strategic locations so the other 2 can mesh to them and cover a ton of ground.
I saw LoRa a few years ago and was very happy a few weeks ago to see that open source Meshtastic has made LoRa a usable technology that's now exploding. I'm setting up a three node e-comm network for my brother and sister, each 2.5 miles from me. The solar panels arrived yesterday. The 8.5 dBi collinear antennas arrive tomorrow. Now that the Chinese New Year celebration has ended, hopefully my WisBlocks will ship today. I'm designing a custom enclosure to print. 🙂
New to meshtastic and this video really breaks it down clearly for me. We will soon have 3 nodes running and need many more to manage the terrain in our area. Thanks for the great video.
I Set up my first node today. It's working well, not a lot of nodes in my area but thankfully I am repurposing a Helium mining antenna so my Heltec is reaching out there.
TU Gil, I shared this video to a local ERC (Emergency responce communications) team I think they will like this and will also encourage the ones that are not intrested in becoming a HAM as you said.
I just got my first one flashed and am waiting on my second one. We shall see how it works!! Better to have something than to have nothing. It also will work on phones with no service (old smart phones that sit in a drawer).
I've been playing around with these for a few days and am looking forward to trying to send some off-grid messages back to base via the mesh from a remote location around 450m ASL in Wales. I have found the Meshtastic app to be rather unstable on older Android devices and Traceroute seldom seems to work, but maybe future updates will fix at least the latter issue. I have added my base device (Heltec V3) to my IOT WiFi network rather than use it via Bluetooth (seems more responsive for both the app and web client). Early days with my experimentation, but looks promising - a good addition to the prepper kit and a bit of fun too - yet to look at the network's resilience to D.O.S type attacks etc. but if nothing else, a good substitute for SMS in areas where there's no mobile signal or the networks are down. All the best.
@@RadioPrepper - Meshtastic app update today appears to have fixed the instability issues with my older Android devices, which is great as I can dedicate an old Lenovo tablet as a Meshtastic interface at the base station. Cheers.
Great idea! Nobody in my county of 130,000 is using it. No nodes. Using an online node map locator, I see several in Seattle, but it's 65 miles away and too many hills for my node to see.

Please dont forget us down here in Australia - were using 915MHz too - hoping, when experience allows to have an MQTT mesh to connect to the rest of the planet. Also hoping to setup some solar nodes but stressing about reliability of RAK wisbloks at this time - I keep hearing bad things!
I'd heard that the WisBlocks are the most reliable of the LoRa devices. The only complaint I've read is that a brown out power loss requires a manual reset, but a large enough solar panel and battery pack on such a low power device should avoid that problem. I'm using 6W solar panels and banks of four 18650 batteries for each node.
very interesting had never heard of this format so you log on it with your phone type your message which is sent on radio waves in a way is it like packet on ham radio ???
Nice seeing a video from you on Meshtastic! Last week I was looking into this, quite curious about it. Tomorrow I'm receiving my first T-Beam, same model you have, got it from Passion-Radio. Being from Reunion Island, I'm not sure there are users around here, but I'll see. If there isn't much activity, I'd be curious to try the MQTT stuff. Later I'll get a second device, probably a RAK so I can do a nice outside installation with a fixed antenna, couple 18650s and a small solar panel maybe. And then I'll test the range between the two.
I bit the bullet before the inflation. I bought one for my truck and one for my house. The one for my house is installed . Not yet with the truck. I saw this video and decided to check the one for the antenna cause before they didn’t have one. When I saw the one for the motorcycle price it went up crazy!!!! How such a small piece cost so much!!
Right now Im testing between 2 units that I own. How do you find others in the area? And range test setting seems to do nothing...I need to research how to use that setting.
Interesting way of communicating. Does it have any store and forward capabilities or must sending and receiving phones be on and connected when the message is sent? I've read that this system is limited to 300 nodes.
No message storage. That's the weak point. It wouldn't take much protocol change to wait for a clear path to the recipient and then transmit a stored message but that may violate some communications laws pertaining to unattended or automated stations?
Question, must some of these Meshtastic / LoRa devices be specially configured to be a repeater? or repeater mode. or do they do their own thing by itself. Will it auto relay / repeat and extend the "zone" for extra coverage if more LoRA (or meshtastic Heltec devices get powered up in the region.)?
Thanks for this interesting topic! I am following Andy Kirby and Ringway Manchester a while now, also about this theme ... was wondering about the frequency choice, what would be the best for us here at continental europe, so 868 MHz should be the "better one" for us ... ok ...

Chicken and egg. The sooner people start, the faster a network develops. One of the fundamental rules of information theory is that a network's utility is a function of the number of nodes. One node, and you're talking to yourself, which isn't very useful.
Noob here, great infovideo thnx v much, since you talk about prepping my Q: Say for example the internet and electricity are down will you be still able to communicate? provided you have some alternative electricity source
@@RadioPrepper Wow ..well I don't want to sound pessimistic but the idea of a total internet/electricity shutdown is not a far fetched fantasy anymore seeing what is happening east of our borders in other words in a doom scenario can be a life saver. What is your advice for the most basic starters kit to build some knowledge and understanding of the system?
i would like to get a Meshtastic but would like a ready out of the box or almost ready out of the box unit. Can i get pre soldered unit? And assembled ?
There isn't generally any soldering needed, other than maybe a battery pack and solar panel and you could use crimp connectors for those if you bought a pre-soldered battery pack.
@@vinny142 just my two cents, but Meshtastic does not rely on any centralised system that can go down and instantly break the whole network. It simply meshes devices together into a device-to-device network, so each of them can help extend the range of the others around. Unlike the phone, or internet, if the provider goes down, it's all gone. It just happenned a few weeks ago where I live after a cyclone. Annoying. So I don't know if using the word off grid is good or not here, but according to Wikipedia's definition, looks like it does. "off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities." from Wikipedia, mentioning "public utilities". Then if you want something that has an unlimited range from point to point without any relaying, well there is still ham radio, providing the best atmospheric conditions for a contact, appropriately sized antennas and everything. But that's something else entirely. Different systems for different usecases.
I tried to mix the devices and they will not talk to each other unless they are at the same speed, it would be great if it could change speeds to allow better distance..@@RadioPrepper
How good is it in relaying text messages across countries??? like for instance from Britain to Greece or Australia? Also, it seems that if each ship and sailboat crossing the Atlantic would have such a device on their mast, then (because they are mostly using the same route, ships and sailboats are always only a few miles apart from each other) they would have constant connection to latest weather reports and marine traffic data. Then there would be no need for AIS, Iridium or unaffordable Starlink.
@@RadioPrepper Interesting that you think that it wouldn't work in the ocean. It seems it has more potential than AIS tech if you add a blockchain-like database capabilities to nodes (plus packet sorting algorithm); and/or introduce a few satellites to the network or super-nodes broadcasting across vast distances. At anchor, yes definitely - it'll work as it is now. Actually, I can see it becoming a thing within cruiser subculture: arrive at the dock, announce yourself and that you have a bottle of rum, anyone with coke and ice is welcome. And it's on.
@@RadioPrepper ...additionally, you can place HF antennas in Cabo Verde, Guadeloupe, Bermuda and Azores that repeat the latest versions of the packets across vast distances, while the receiving vessels form temporary local networks among themselves sharing information P2P through bittorrent like protocols.
The curvature of the Earth will get in the way.. You might get tropospheric ducting propagation occasionally, but not reliably. I doubt long distances would be practical. It has to be line-of-sight. Mast top to mast top can be quite far, but crossing oceans, unlikely...

@@PeterJavea SMS is also far more bandwidth efficient than voice. In most places, when there's an area wide emergency, the authorities say to use text instead of voice, so the towers don't get overloaded.
I like gadgets and all but this is some J6er crap. The useful range is bad, the infrastructure has to be supplied by the user. And its easy to jam. All these meshtastic videos are just cash grabs using monetized links. Again it's a cool gadget but real world its junk. Might work well for cartels and criminals in certain situations. But would fail in a fubar situations. Your screams have a longer range.
What's J6? Anyway, it's a cool gadget anyway for those of us interested in radio, especially small data packets over radio, including hops. I could say I was interested in hops, but that's a different interest!

The maximum range has been 254km mountain to mountain with LOS between omni antennas. RAK boards are more energy efficient and better made, IMHO.
... and without mountains range is like "less that wifi"?
