- Cool projects are rare. Here I found one I want to show to you. An off-grid personal communicator. It includes a lot of new technologies: ESP32, Smartphones, LoRa, BLE, GPS, Mesh, and as you see, 3D printing. And it solves a problem that could be seen as a human right: Personal SMS style communication everywhere in the world, without the need for any infrastructure, and without mass surveillance. In addition, it shows the location of all your friends in your group on a map on your Smartphone. Everything open source, of course. How cool is that? Even "Sexycyborg" Naomi Wu likes it.

I must admit, I'm quite taken by this concept.
Looks like Clive is also a subscriber of the man with the Swiss accent.
I had thought about something like this when I first saw LORA on this channel, glad to see someone is way ahead of me!!! I am curious if the "relays" can work without being paired to a phone. I assume so. They could even be powered/recharged by solar or other sources...
@@BloodBlight yes to all of that
@bigclivedotcom same. If it advances to so that messages propagate instantly it could make for an interesting cueing system for shows or backstage coms. You should be able to easily link messages to a relay of some sort to power an LED or something similar.
@@templebrown7179 It's THE place to be. Trouble is I'm old enough to say "Be there or be square" :(
Years ago, I thought "There's gotta be a way to invent a cell phone that doesn't use service providers, does its own transmitting and receiving, and the more people in an area that had them, the better they would work. If ONLY I knew SQUAT about electronics...."
There was a Tv series a few years back where people were always watched and analysed by a computer linked to all cameras and phones. It sent messages to this person about saving certain people. When the competing bad computer was launched, good guys had to use this type of network to communicate. Since LOS was required nodes were set on the rooftops. Might have been this tech that fueled this idea. I thought how handy this would be in a surveillance state.
@@2bczar4u The idea is fundamental enough in of itself that surely many people have had it long before it started to get traction. I thought of a similar approach to a distributed internet when i was in middle school. Ideas are only as good as the resources available to implement them.
The HBO show Silicon Valley had the company pivot into distributed internet in the fifth season. These memes are out there, they just need traction. This project helps like snow tires in the traction arena.
2bczar4u PERSON OF INTEREST! Great show but it would never be allowed on the new SJW /Far Left networks.
@@PowderMill yeah, they would probably flip the story. Everything good would be bad and the bad guys would be justified. Fekken idiots destroy everything.

Look into the new administration's push to criminalize independent/unofficial broadcasting.
I was puzzled when I first heard about it.
I am TAKEN ABACK that there appears, as per usual as of late - NO pushback that I have seen.
If anyone is aware of any efforts to actually INFORM ppl, please reply.
I am disheartened with the pained awareness most seem to have something impacting and diminishing their attention span(s) (almost like that MIB neuralizer?)
I would like to SHARE with concerned ppl with large channels in an effort to steer the support of even just many if not most of those subscribers.
Glad you finally on board.. Please spread the work.
Thanks for this amazing video. A lot of people learned about Meshtastic because of you. You rock!
Thank you! I see taht it also got traction in the HAM radio community. I just started a second channel in this field and probably I will cover the project again. Particularly the more enhanced functions to build networks .
@@AndreasSpiess yes thank you for promoting this. Its something thats been needed for a long time. decades ago we theorized this in seattle and implemented some variations of this in our local neighborhoods but things have really progressed now.
Wow this is perfect timing for what's going on in the US right now

@@lumberjackdreamer6267Just the same ole treason and sedition
Japan has a Constitutional ban on military secrets - so you should be able to operate a very broad band relatively powerful HF CDM, which would be undetectable, and even if detected - it would still be legal - in Japan. From there, despite laws, people would export these units to more repressive countries - like the U.S. Once there are a few thousand of these units operating around the world, the genie would be out of the bottle and secure secret communication would be possible - which would be enough to topple repressive governments who don't clean up their act. THIS could change our world for the better. Keep up the good work.
Another thing I admire about japan is that the government seems to respect their constitution. The reason they didn’t shut down businesses and lock down is because the prime minister recognized that according the their constitution the government does not have the power to tell people what to do.
Got any links for me to read up on this???
The need is to operate without any government. They are all repressive

If only the mere mortals like me could just buy this online already made.
Then talk to other people who also own one, then big brother can’t keep snooping
Dear Andreas. Thank you for the time and effort you put in your videos to educate us on the topic. Looking forward to seeing more from you :D
You are welcome!
The way you are preparing stuff and communicate it is absolutely phantastic. Greetings from Germany and keep on motivating your community.
Wow, thank you!
Im new to this space and want to thank you for such a clear and concise introduction. Thanks also for Disaster radio, amazing project. Your work is fascinating. Im ready to take the next step. Thanks.
I'm ready as well!
You know you are changing the world with every video. God bless you!
Thank you!
I am just starting now. 3 years after this video, so anxious to see all Anfeas's newer videos on Meshtastic.😎
These need to be mass produced NOW!!
If it was, they would be tackled by censorship and privacy as always. Has to be made in secret or all the big corporations will literally try to stop it at all costs.
In China?
Downloaded this video before it mysteriously disappears ;)
Good concept. And post it to a peer-to-peer network ;-)

Cool project, I wrote a similar application just for fun when I got a pair of T-Beams (also securely) communicating with Android - over 3km range in my brief testing. The The T-beam is ideal for this mesh group communications task.
Maybe you join their project? The still need some help...
Oh yes we would love the help and it is super fun/friendly

Just a note to you I love your recaps enjoy really listening to you do you seem to really know what you’re talking about thank you so much I just subscribed today.
Welcome aboard the channel!
Awesome, thanks a lot. People from the Philippines will need this a lot in the next years.
You are welcome!
Just flashed it! Due to earlier videos of you, I do have TTGO T-beam and other LORA-modules in stock. Thank you! This sunday project is salved
Great! So you are a tester now...
@@AndreasSpiess Not so fast OM! I have the T-beam and my Wifi-Lora-32 up and running, but my other toys are too old, I think: a Nexus 7 tablet and a S5neo, I stole from my wife. The Android app ist not runnig smooth on these. I can´t setup/alter a channel. Bluetooth is unstable and so on. I never bought a smartphone or mobile myself, always use old ones I found in the trashbin of my children. There is no manual how to setup/use the app?
You probably have to ask Kevin for that. I do not know all the details and prerequisites.
Some old bluetooth implementations were pretty buggy. Try rebooting the phone, then pair the device in android settings/bluetooth then launch the app. If you have further problems just post in meshtastic.discourse.group/ and we'll help.
@@khester Thank you ! That helped, connecting, but I can´t correct Group setup because the lock symbol does not open ! Could not click it open!?
Perhaps a good future project to add to it would be a Raspberry Pi Zero W attached to one or more LoRa modules to allow interconnecting LoRa mesh networks with Tor or I2P?
You are welcome to contribute to the project. They have a collaborative room
I am working on a new network protocol specification that includes encrypted tunnels as a core feature. The basic idea is to use latency measurements between hosts to derive addresses in several dimensions using basic gradient descent. The first node in a network becomes the origin, and every new node calculates and self-assigns an address encoding coordinates after gaining latency attestations from neighbors; all other nodes can then verify the address very quickly using the latency attestations.
One of the benefits to this coordinates-as-address system is that routing becomes a matter of forwarding to the neighbor who has the lowest distance from the target address. How to make that an efficient look up is something I have yet to formalize, but I have outlined other things, like gaining guest address leases from hosts, bridging between networks, neighborhood gossip protocol, anti-spam policies, etc.
This is a really dope project! Thanks for sharing and I get a kick out of the miniature hand lol
Glad you like it!
Great, I started looking into LoRa mesh, this is a valuable hook for research.
Very good. And maybe you can even enhance it?
Almost exactly what I was looking for for. Thanks!
Glad I could help!
This project sounds perfect for when hiking in remote areas where cellular coverage is limited (or when you turn mobile data off to save battery). It would be great to see each others' location and negotiate on e.g. lunch time. As you say, a lot of interesting technologies are combined, so it sounds as a very interesting project to work on! Thank you for this nice explanation.
I think you are right on the spot with the usage...
This is just the beginning I can see voice followed by video calls facilitation along this mesh network. It might be another revolution in communication.
I do not think so. Because of its limitations it will only cover a niche.
@@AndreasSpiess what would it take to get it there?
Would it even make sense to get it there?
If so, would it the material or resource to do that outweigh it's current advantages?
@@MR-nl8xr Wifi links to all of your neighbors you'd care to communicate with. Hook up using the same equipment WISPs use. (Point-to-point wifi links.) We were already there years ago. But first you'd need neighbors that want to go through all of that trouble and expense just for a "maybe". (Because you could just chat with them over the internet while that's up and running.) T-BEAM is a ~$35 "maybe" if you just buy one node. Setting up your own wifi-neighbors-infrastructure could get into the thousands of dollars / sky is the limit. (Not saying it wouldn't be cool. Do it!)
The tiny white-gloved hand was a nice... ...touch.
Thank you. It has quite a few fans on this channel ;-)
That’s perfect for our cruise ship holidays. The problem there is that WiFi and lte are incredibly expensive on ships, so normally it’s not easy to communicate on a 350m long ship :-) Lora should even work in such a steel-y environment.
Very good idea. Would be worthwhile to check how the steel influences the range. I have not "cruise plans" for the moment :-(
I haven’t built any LORA projects yet (I have a long queue of projects) but I’ve loved learning about it from you in so many videos. The content is always so practical and concise. I’m amazed how you manage to fit so much into a short video without sounding rushed. Just perfect. Thank you.
Thank you for your nice words. It probably takes a little longer on my side to save you some time. One man spends a little more and thousands can save a few minutes. That is what I strive for.
I got a couple of these for christmas and came back to rewatch some of your lora videos. They have improved the meshtastic firmware a lot. You can now connect them to your wifi and have them put messages (encrypted) into an MQTT server that is then picked up by all nodes using the mqtt server with the same channel name/key over the internet and rebroadcast. Basically, I could set up a node here in Texas connected to an MQTT server, you could set up a node in Sweden connected to the same MQTT server both with the same channel names/keys and I could send a message from my phone that you get delivered to your phone. All encrypted via the mesh network and sent over the internet.
Out of the box with the stock antenna it gets good range. From a shelf in my house to the other one being on the dashboard of my car, I got 1km. Bet if I install a high gain antenna and put it on a mast I can get much further.
Thanks for the great videos.
Good to know. I did not follow the project. But this is good news!

I'm very interested I'm so tied of being spied on everything you do on these smart phones is recorded and I mean everything. This technology is in our TV's too so this is so interesting I would love to see this product grow into a great private communication device
Great Idea 👍👏

not only is everything accounted for recorded but the behavior is also being inferred to extract some future behavior. you cant just do something. you do something and its applied to all knowledge of psychological data and discoveries to label the mind state, personality type, health, ect ect ...
Pretty much all tech started for military use.
So I’m excited. I think this is going to be very handy. For who? 😬 we’ll see

Cool project.
One thing we have to have in mind is that there are people that will use that solution for the good and also there are people unfortunately use it for bad things. But was always like since we began to be technological species.

@@AndreasSpiess Sure!!!
Nothing wrong with using GPS (a received signal) and sharing with others that you are in encrypted communication with. There is a thing called being too paranoid restricting usability.

I've been in the decentralized community for a while. AtHoc networking is unreliable for the reasons you mentioned but also because lag increases with every hop regardless of distance. GoTenna mesh sought to solve this problem by allowing certain users to act as gateways and then its a matter of connecting gateways. The privacy issue is meant to be solved with encryption, but the low throughput of radio frequency usually encourages non complicated text data only.
Althea mesh is more of a WiFi router and extender linking project and the mix of these two schools of thought (pocket radio and WiFi linked gateways) may be the best solution to a decentralized trust less network for we'll say protesters as an example.
Yeah, protesters AND patriots !!

i've been dreaming about this kind of exact solution for years, even thought at some point on getting a radio amateur license ! now i see that...amazing ! my main concern would be the range....basically if no one is in my area, then it's bad luck...
As a HAM you have more opportunities, of course...
It's making use of existing infrastructure, running as a layer on top of existing smart phones in the surrounding area. So this will not work where there are no other smart phones in the area.
@@cryptixdaemon7236
Yeah but realistically, where on this planet are there no cellphones ??

this is one gem =D thank you!
Glad you liked it!
it would be interesting to connect the device to a home Wi-Fi router to share the features with any phone connected to your home network.
this could also be an useful technology in case of riot/revolutions, natural disasters, solar flares, zombie apocalypse, etc
These devices can be used for many different scenarios, you are right.
problem with the solar flare scenario, is unless you build a faraday casing (and at that it must be well built around the chipset only and not the antenna; may interfere with the transmission range overall), the chipset will most likely be destroyed from the EM burst.
I do not consider this technology to be very secure. I would not treat it as an impregnable communication platform for conflicts, only an alternative when the normal telecommunication grid goes down.
Thank you for enlightenment that we have this technology.
You are welcome!
You are amazing. I love your videos. I wish you all the best and I am waiting for next videos :)

Raymond Biskner
If it exists, it can be found. If it can be found, it can be infiltrated. Multiple alphabet soup agencies exist to spy on everything that exists. Poor opsec to have it broadcast your location to anyone ever. There is no need for any of my friends to know where I am at any given time. I don’t even have find my iPhone on in the vague hope that it would be harder for someone to track me. When my boss showed me how he could see where his son, daughter, and wife were at any time I reconsidered why I need a smartphone. For now I still have it, but I sure don’t take it everywhere anymore. Now I keep a flip phone to make calls when I want to go incognito. Battery out and simple pay as you go plan. I love the idea of untraceable and uncrackable technology, but then y’all go and put a “here is all of your friends on a map” function like opsec doesn’t exist.
This project has been on my list of cool projects for a while now - I placed an ordered over 3 months ago for a couple of the T-Beam boards, and still waiting. There are a number of these type of projects out there.
I liked this one because its integration into Smartphones... And it is maintained.
I had the same idea a year ago, great to see that smb implementing all that stuff to life, so cool.
Now it is easier for you...
You probably have slightly different ideas that exactly what Meshtastic is doing. (Everyone does.) This is where open source is great! Do those ideas and share!
I've been looking for something similar to this for my cyberdeck build.
:-)
this could easily be used during war time with proper encryptions.
I assume they have better (and more expensive) devices.
@@AndreasSpiess of course they do!! While I was in(radio op/maintainer) they had radio arrays that made this look like smacking two sticks together. I am saying on a large, low budget scale, these could easily be used by gorilla fighters to keep a semblance of organization. I would be surprised if these weren't completely outlawed in the states if the gov couldn't easily find a way to break said encryption.
Joshua Williams While it will be easily decrypted by feds if they wanted too you would just have to go back to using code words for things. I’ve used radio SOP’s on un-encrypted frequencies that would take people a long time to decrypt. One paper on each end, for example: Resupply = AX21, Pick up point= AX45 etc. only need to encrypt key words and words that has essential meaning to the message. Group words in the same category together for easy decryption/encryption.
Joshua Williams I’m rambling a bit but I’m sure you catch what I’m putting out :). Have used this method of encryption when being forced to use un-encrypted nets such as civilian radios or phones
This is USA specific, but I imagine that it applies to many other countries too. I heard recently via another YT channel that ANY type of code words or encryption are illegal on ALL publicly available radio bands. Laws are tricky.
Awesome ! Really interesting and worth experimenting !
For many of us it is probably more an experiment than a real usage.
Intresting project , i can see how huge transmitting distance and unlimitted power supply can easily be added to this device .
Unfortunately, it will not be legal if you do so.
Seriously though, we need more of these kinds of technology more than ever before with all these censorship going on. Its about time we decentralize our need from the megalithic telecom industry. Who agrees?
but no one sensors your text messages to and from family and friends, which is all this does. Good to not be spied on by Apple/Google/Amazon, but you have to disconnect all Google apps etc or use different OS not android or ios
@@sophiesmith5922 hm. Right. Well do u have an alternative?
I'd imagine you could hard wire this into a home or vehicles power source to allow for direct communications.

Friend, very good video, first-rate information, thanks for sharing.
Glad it was helpful!
Thanks for interesting LoRa news!
You are welcome!
Hello Andreas. I'm watching from a long time to your videos and I enjoy your professional styles . Especially because I'm a professional board design engineer with a lot of experience and I'm working and designing complex pcb boards. I don't have the opportunity to write to you in order to express my admiration but now I have a question so I used the opportunity to say you how much I like your channel.
So now the question. I like the idea of the project from this video and also I know the M5stack project. They have there a Lora stack and ESP32. And now they have a new kit, M5stack faces that look very close to a communication device. So from what I understand will be now problem to make the Lora mesh communication with a M5stack faces and added Lora stack. So what you think about this idea ? If you think it can be possible maybe you can do a video about what to order and how to assemble and program a device like that. What you think about it?
The Meshtastic projects supports several architectures (this is easy with PlatformIO). So you for sure you have to define the pins used for the LoRa module and maybe change the LCD, if M5stack uses a different one. But it should not be a huge task. All LoRa modulesw seem to be supported.
For the moment I do not plan another video about tis project.
It would be cool to integrate this with ATAK.
Maybe you join their project team?
Now that ATAK is open source, I'm trying to do just that.
Yeees!
They guys on github that created the "freetak" server are working on that and attempting to build it into their server code to be compatible!
Wow! Will this be our self-reliance kind of BlockChain electronic decentralized communication? Great, we are going to be like those fellow ETs! God bless this project.
:-)
Andres you highlighted the project I had been thinking about for some time. thanks for showing the project everything is simplified now. in this way you can encrypt the texts of the sms before sending "obviously exchanging the encryption code in the hand with the person you want to communicate" for much more extreme security. Even if someone puts their noses on the network, they still cannot know what is written in the text message
The key is part of the group name.
@@AndreasSpiess Sorry Andreas you are right, I misunderstood what I meant. I meant to use an app in addition to encrypt the text in Wirlpool, Serpent, encryption before sending it in the dedicated App in mesh communication. That's why I said to exchange the key at hand to avoid the transmission of the key in the network mesh. Such a technique is also used in Walkie-talkie radios with text messages. Basically the generated strings of the encrypted text are sent as a normal message. if a stranger looked at the message he would only see strange strings that make no sense
Where can I find a “plug and play” version? One I can buy and use, no assembly required?
I heard that TTGO sells a version with firmware. But I think it is not a product like a Smartphone which just works.
I still don't understand how these work underground :)
Just burry one ;-)
Fantastic, well explained, love concept.
Glad you liked it!
I wish I understand stool all the nuts and bolts. The idea is brilliant! Keep up the innovation I would love to see this Takeover

I wish I saw this Video, before I created something similar then this… I also created a mesh implementation, which has the same Features, but it runs on an Arduino Nano...
Oh, interesting, is the code uploaded somewhere?
Search Facebook for TR - Link... I have an OTA installer for esp32's... The code itself is not public...
The fact that they be were made in silly con valley is concerning.
The source code is open and there are a lot of options for hardware. So where is the concern?
Great video, very educating. I hope to see the NRF video soon.
NRF?

Thanks for the detailed information!
You are welcome!
If Sexycyborge is interested is the CCP also involved?
"No mass surveillance" but you need to use your smartphone...
...exactly. I don´t like "smartphones". They are "too smart", IMHO... ;)
It can be a disconnected bricked phone. It only works as message input and output because it has a keyboard...
@@screwthishi5thing How does that work?
@@salty_armorer4027 how would someone track you if you're not connected to a regular cellular network? They couldn't. You'd only be using your phone as a terminal for the mesh.
@@screwthishi5thing I'm under the impression that a bricked phone can't do anything except 911 calls, so how do you get the app required for proper function downloaded onto to a bricked phone?
Very interesting In fact might be the right solution for certain Industries !!
Maybe, yes.
Hmm Informative one. Thanks for sharing
My pleasure
Do you need to share your location with this?
"Hard to track"
No
as far as i could tell, if you don't have your gps on, the device defaults to it's own location. It only shares your absolute location if you intend it to?
I could be wrong though....
In the configs you can also look into changing the hardware utilization...i mean you own the hardware, why not do some debugging and test it and let us know ;)
That’s just how I would do it.
Nice work.
Thank you!
Amazing Video!!!...Thank you very much!!..
You are welcome!
Another board option, our new Turtle LoRa Board uses an STM32L4 being able to run up to 10 years on AAA batteries. This would qualify for something like this.
Now the interesting part, we at RadioShuttle.de (new business organisation applied last month) working on a LoRa messenger. It is based on the Turtle board with a buzzer and gets connected to a Smartphone via an OTG cable. This allows pretty much private peer to peer messenger chat communication. The LoRa board works stand alone and beeps when a message for you or a group broadcasts arrives. We are looking for more than month of uptime for the messenger boards, once something arrives, connect your smartphone as a user interface device for the messenger (no WLAN, LTE, BLE, can work in airplane mode).
The idea is, that this allows emergency communication, when nothing else works e.g. outage, areas with no coverage, etc.
Great video like always, thank you

PS: The legal part of this topic is some more complex, I heard that the US arrested an Canadien company owner because he build a truly private Android phone with encryption. My opinion is that we should have a right of privacy, which is given by law, however the governments like to ensure that they can spy everyone (without court orders).
Great! OTG was also discussed for this video. It saves the need for BLE but maybe is a little uncomfortable for use I also think there are two use cases: One for short events where speed is more important than battery life. And another where your focus is where long standby times are more important.
BTW: I like the idea of a "buzzer".
