- For all you Meshtastic nuts out there we needed a central point where our nodes will show their position on a map. Of course in a doomsday environment where the internet goes down, this would be useless, but for now it provides a great tool to see who's nearby and assist with placing repeaters and routers at strategic points around the world.

Would like to see more Meshtastic videos? Yes please :)

More to come!
Then make videos
I believe this needs to be spread. Off grid long range encrypted is the way to go
Meshtastic seems to be taking off to an amazing extent.
I'm about to start deploying several solar nodes in a mesh to repeat weather data and slow-scan pictures from mountains 37 km away and 2,000 meters higher. Should take 4 or 5 intermediate nodes based on solar garden lights.
That’s awesome!
SSTV over Meshtastic?
@@mr_spoons Some folks from my local makerspace did a high altitude balloon with pictures (SSTV essentially) over LoRa and it worked. The data rate is low but it's worth it for a static picture. I'm my situation I'll be using directional antennas to not pollute the spectrum.
@@Peter_S_ I can't see how the Meshtastic usage of LoRa will work with SSTV unless a different app is used to get the data into the mesh. I can't find any info on this.
@@mr_spoons Yes, the framework for picture transmission will be custom. A capture request from the viewing end will initiate a capture at the source end. The picture data will be compressed and then transferred very slowly as a series of packets with a check sequence and retransmission scheme managed by little apps on either side to make any retransmission more efficient. I'll admit it's absurd to send picture data over low speed links, but it's more of a demonstration than anything else. When I first heard of pictures over LoRa I shook my head a bit, but it does work. I'll take the picture data to a new frequency with a fully private mesh if necessary to not pollute the spectrum for others.
Great map with auto updating. You mousovered my Brighton node after you clicked on the node in Hove :-) Am looking forward to plenty more exciting Meshtastic videos from you !
Just discovered Meshtastic today and watched a couple of videos. Yes, it is something I'd like to see you cover more of.
Very nice! Thanks for reporting on it!
A couple of years ago another local ham and I set up a 4 node mesh in our town. One at his house, another at my rental house about 2.5 to 3 miles ENE of him, another solar powered node I temporarily placed in a public park ~2.5 miles NNW of my rental, then a 4th node at my house another 3 miles NNW of that one. We really needed more nodes in between, but we did manage to pass one whole message from his house to mine.
I've been meaning to ask the town if our local club (K5SRC) can mount self-contained nodes on public property and/or utility easements.
I have 4 nodes running in Victoria, Australia. Unfortunately it hasn’t fully started here. Though I’m getting over 40-50km distance from home and works 70-85% of the time on sending messages through. Can’t wait till the audio versions appear!
915MHz band in AU?
I'm in northern Victoria, planning to set up a mesh from my town into alpine valley areas.
Interested to visit Melbourne and actually try to connect to other nodes though 😅
Me and a friend in Ireland wants to set one up. ;) A hamshack hotline User.....
THANK YOU. I was using the canvas map, but it sucks. This map is Much better
Brilliant I’m getting involved
Great video 👍
More of this please.
Sure! :-)
Bought one right now!
thanks for the video bud, im hoping to push meshtastic in the hull area
Go for it!
@@TechMindsOfficial definitely, I've got friends setting up in Doncaster and just waiting to hear back from a friend in York.
Hey I saw my node out in the middle of nowhere in California. nice. However I don't plan on using MQTT other than that one test I did. Just a personal preference as I believe it defeats the purpose of being an off grid communications platform.
Great !!!
There seems to be some missing info or I have not seen, can you use different modes like long-fast talking to long-slow, etc. if my device is configured differently will it connect to the mesh?
I just found this a few days ago too, great to know if someone can mesh with me (nobody yet!). Hope it gathers some developers to keep it growing
This looks like a great ideea, if you want to plan something in advance. But personally I can't imagine what :)
The usecase I can relate with, for the lora communication devices, is in case of disaster, as mentioned in this video. Natural disaster or human made, like war. And for both situation, I don't see the benefit of a node gps position. Especially in the war scenario, this will be a security issue.
Just my taught. Keep up with the videos!
thanks :-)
You're welcome!
I just ordered some LoRa kit, it looks interesting. APRS on steroids...
So, you look at the MQTT server from Meshtastic. But do you look on channel or topic as well? The standard msh-topic is overwhelming and annoying besides your first few tests, and there are channels and topics made each new day.
How do you get them all on this map?
Thats down to the developer to decide which topics to subscribe too. According to the comments made on the Reddit post, they are aware of this and looks like will be using the standard location topic that gets set when you setup the node. For example for EU it would be msh/EU868
The meshmap is not live. It shows nodes as well that haven't been online since days. It's helping anyway.
I would like to have the information if a node uses 433 or 868.
They are building in a timeout, according to the reddit thread, which will remove nodes that have not been seen for a certain period of time. I guess they could start to add filters, so we can set a "time" filter ourselves. Hopefully they will continue the project and improve it for the community.
@@TechMindsOfficial I am currently disappointed about the coverage. With my 868 node on a very good location with a cavity filter and 9db antenna I receive nothing. It's not the hardware, it's measured already with vna. Maybe it's the esp32 that seems to reduce the gain of the internal AGC when strong lte repeaters are in line of sight. Regardless the cavity filter it seems that the noise affects the board itself. I have no other explanation for receiving nothing despite I have a 868mhz node 10km away in line of sight....
@@saxpert Get another node and use the range test feature. That may help. Alternatively use an SDR to look at the spectrum around 868 to see if there is some splatter from a rogue device etc. Also, check that the cavity filter is actually working correctly, might not be tuned correctly or causing too much inline loss?
@@TechMindsOfficial I know quite well, that the lowloss cable, the filter and the antenna and the spectrum is fine because I used the hardware for OGN before.
The spectrum behind the filter is fine, no noise only lora, flarm, car opener, sensors...
I ran this node at my house before and it received the same stations as another node. It's a lilygo paxcounter.
I'm still investigating, the problem is that you don't know what's happen in the chip.
I noticed that the esp32 is more sensitive with noise with gfsk modulation but lora sensitivity is degrading as well when strong LTE stations are around. I will test the range feature but what should I do with the csv data?
Maybe I'm missing something, quite possible.
Without GPS in the Meshtastic Device, how does it know your position.?
Either static fix or when you use the app from your mobile device it uses that gps location data.
@@TechMindsOfficial
O.K, I saw some image where somebody added a GPS Module to a Helltec V3
@@4X4-RADIO Yep, you can also do that too.. Thanks
Ummm... what am I going to use Meshtastic for in day to day life?
Meeting women? or Men?..... Essentially it's a preppers tool, but the popularity of it could come in a wave just like CB was back in the day. Plus, when setting up a node you will learn an awful lot, especially if you have not done anything like this before.
I'm intending to use it to monitor my elderly parents house for motion (No motion for a few hours = bad) as an alternative or backup to a more traditional Internet link that's currently in place. Only problem is they are too far away for a point to point, so I need a few more people to run up nodes along the way...
Wow, absolutely nothing in the entire state of Arizona 😕
Give it time, place your device (& antenna) as high as possible, and leave it powered 247, once you make an connection with someone else the ball is rolling
There will be, just no location data or not on MQTT.
Shout out to Lewis @RingwayManchester who's also been covering this and thanks to this video might nudge me buy a node to bridge a void between Milton Keynes and Aylesbury in the UK 😊
Where are you located? Somewhere in between I guess then? A repeater inbetween would be awesome, thanks!
I'll post the exact message I sent to "M0DQW_Base2" which I believe is you this morning (2024-02-24) after receiving my pair on Heltec V3 on Friday:
"I just looked up your HAM call sign, M0DQW and was utterly gobsmacked to find out your TechMinds and indeed I follow you on TH-cam! 👍"
Small world indeed! Very curious if you're doing a lot of the heavy lifting your end (pointing antenna in my direction, etc) as my setup is literally a Heltec sat in on south facing window sill 😛
I am based in Buckingham town, some 21.8 km away. As mentioned I'm keen to potentially help bridge a gap between MK and Aylesbury, if possible. Perhaps with Yagis pointing in the right direction? I'm very new and amateur at this so any and all help is welcome!
@@TechMindsOfficial Hi! I finally received by pair of Heltec V3's Friday and Saturday woke to find two nodes hailing from Aylesbury; one of which I believe is yours "M0DQW_base2"? I'm getting your setup is far superior to just sitting a stock in Heltec in a south-facing window and crossing fingers 😁
As I'm very new and very armature to all this rushing out to buy a "fancy" stuff like directional yagis might not be the best move, but very willing to hear your advice on bridging that gap.
Forgot to say I'm located in Buckingham town. Would consider setting up a repeat or other Meshtastic "role" once I've gotten to grips with simple peer-to-peer stuff (and that justifies the outlay!)
@@ethzero Ahhh yes! That's my test node that's in the loft on a short amazon lora antenna. I have been playing with Yagis, pointing north, but not from that node. So you received my node from my loft! ;-) Unfortunately I did not receive you though.. There is a router at Whitchurch, so maybe it went through that, but if you could reach that router/repeater then I would of heard you as its strong here. Middle of next week I have the 2.2m Paradar 11.5dBi antenna going above the roof on my house, so maybe we might be able to make contact then. I will be changing my node to a permanent node, most likely just called M0DQW_Base, so if you see it, try and send a message! :-) I just gotta figure out which one of my modules to use! lol. Cheers for the info!
My app says not to use MQTT in my region. Europe 868.
You can enable MQTT but NOT enable the MQTT to local mesh setting on the channel settings, otherwise your node will be flooded. That means your location can still be sent to the MQTT server but you do not receive all the other worldwide nodes.
@@TechMindsOfficial so Ive enabled MQTT and not the client proxy? I’m on iOS. Can’t find any local mesh settings. Cheers.
@@paulr4279 On the "channel 1" settings, which is the primary, just make sure "upload mesh to mqtt" is checked, but do NOT tick "mqtt to mesh" otherwise your node will be flooded. Hope that helps. I will cover this again in a future video. Thanks
@@TechMindsOfficial cheers, mate. I use msh/UKWide topic which is less busy than EU.
Unfortunately, the only node you can see in INDIA is mine. There is zero activity here in india.
Time to start canvassing and handing out leaflets! I'm suprised actually, as I thought India would be one of the hot places tech like this.
Offline now! (17:08GMT 13/2/24)
@@dougle03 yes, there isn't much use if no local traffic is there. Depending on mqtt kind of defeats the purpose of having a standalone mesh network. That's why I have taken my node offline. Will tinker with code to transmit some sensor data over mesh for now.
Uses MQTT which isn’t ideal I think
Just don't enable MQTT to local Mesh on a channel and you will be fine, you will still only see RF connected nodes and no internet nodes. Then it's fine.
@@TechMindsOfficial Thanks for that, I thought it was either on or off.
@@TechMindsOfficial Could you cover MQTT, with more depth in a future video, please.
Yeh sure! No problem
That would be really helpful. Yes please @@TechMindsOfficial
