OK, NGL, my #meshtastic #solar node is fucking sick.

It could run for years with no maintence.

6dbi fiberglass antenna, solar panel, MPPT board from DF Robot, absurdly large battery pack, discharge protection circuit, temperature & humidity sensor, remote administration...

And I plan on running the solar panel through a current sensor so I can keep metrics how much power we're generating. That's the only significant update I want to do.

I think it might soon be time to do a bulk buy and crank out these nodes. They cost about $200 each, but considering RAK Wireless is selling a node with smaller solar panels, smaller batteries and a smaller antenna for $230 that, I'd say I've done well.

Some fellow hackers from the local 2600 meet and I might crowdsource a few nodes and just provide coverage for all of central Illinois. Once we have solid coverage, it'll be more appealing for people to carry devices. Once they are carrying devices, it'll be easier to get some of them to run a solar node to make sure they're getting the best coverage possible. This could set off an unstoppable chain reaction, and I'm all for it.

I just gotta keep grinding, perfecting my hardware rig, figuring out all the gotchas with the software and documenting the workarounds, shafingb what I've learned and offering nodes to people who want to just buy one instead of putting in all the work that I did.

Fuck yeah. Cool af

Seems like a good strategy to help build a strong grassroots meshnet

I just got my first node 2 days ago. The tech is pretty amazing. The whole city I am in is almost covered. Either by clients or routers. Would be cool if you share any details on your solar node so maybe I can put the few more nodes where there is no coverage.

Yeah, I plan on documenting everything and the person who runs http://hackspace.io/projects invited me to put it there. So that'll be my first pick. I'll like to it from here, naturally.

OMG, that $230 isn't for a sopar node, that's just the battery and panel for a solar node! And it doesn't even output 3.7V DC!

I guess I've got a slammin' deal.

You got the signal issues fixed?

I did. Antenna got disconnected before I put the strain relief in. 🤦‍♂️😆 It's STRONG now. I just did a small range test by waking to the bank & grocery store doing my usual errands.

I plan to do a larger range test when it's not raining out.

Hi Dr.Hax nice to meet you 🤝😎 This is the kind of geeky brilliance that gives me hope for humanity post apocalypse. Mesh now, thank yourself later!

shut up bot

Unfortunately I'm a human being but I'd really like to be a robot! They are definitely less assholes than us

I'd buy one at $200.

what's the bandwidth like on these things?

my house internet is 500mbit/100mbit

doesn't really seem that useful except for sensors and text messages from what impression i get of the bandwidth of these things

i mean, that's nice for what it is i guess

Low. That's exactly what it is good for. Plus, the mesh nature of the network is rather robust with enough nodes and elevation.

These devices were (and are) invaluable in disaster areas and when all the internet infrastructure is disrupted. An example of this is what happened last year in North Carolina and the surrounding States. Meshtastic nodes played a critical role in helping coordinate rescuers relief.

yeah, i see the use for it, all kinds of uses, and it pairs well with nostr, especially if you make a more bandwidth optimised protocol encoding, plus, you can flip the model a bit because mesh nodes are peers not master/slave connections, you could have nostr relays in your place and on your devices and their location is propagated and other nodes can push messages to the network listener

Yeah, it's not an Intetnet replacement. With the radio setting I'd get 1.07kbps. The max is 21.88kbps. But that's not the point of this network.

I also am working on an 802.11 mesh network, which IS high bandwidth. The problem is that it's short range (typical wifi range). This is the trade off with radio.

Long range, difficult to disrupt, but low data rate or,

Short range, interference easily causrs packet loss, but high data rates

Here's the page with the speeds that I quoted. https://meshtastic.org/docs/overview/radio-settings/

And here's the project that I work on intermittently which in intended to do 802.11 mesh networking with whatever gear you havr lying around.
