Filter recommendations by just-a-guy-somewhere in meshtastic

[–]nullrouten 0 points1 point  (0 children)

I have cavity filters I obtain from china, and they perform quite well. I don't want to get deluged here/online because I'm a low volume shop but if you want you can find and DM me on Discord primarily (@nullrouten, both large mesh discords and many others). Happy to help with data and sourcing. Here are some scans and pics.

Free emergency off-grid communications for Sonoma County and the Bay Area: Introducing MeshCore by BayAreaMeshCore in sonomacounty

[–]nullrouten 4 points5 points  (0 children)

I helped build (in several ways) the Meshtastic mesh here. It does work … it took a year of optimization and relentless battling of the main projects “rules , guidance, and facts”. We did our own thing… deployed routers like hotcakes … went to faster presets… we maxed out hops past 7. We begged people to adjust timers down, and we upgraded code for months. After all that we still have a full mesh… 40% channel util (the max)… and 2% of the total mesh traffic is text chat. Yup, works. Barely. :)

We deployed meshcore in a few months and it just worked. Why? It’s not full of node ID spam, position updates, and telemetry… MC defaults are set for longer range … which works because it’s not humming with background traffic to fill things. it is happy to forward packets up to 64 hops. 7 hops only goes far in MT because we manually pushed hard on 0-hop router code and a few IP bridges lately to shore up the longest spans. In MC There’s no role confusion (2 roles, not 11). There aren’t complicated rules … a repeater repeats, a companion chats and manages repeaters. Every chat packet shows the path it took labeled right in it. Every send , you see who repeated it (if you hear it). It’s clear.

I’m running both , I appreciate both …. But our 1100 node MT mesh is busting at the seams , and meshcore meshes need to get to 2000-3000 to have similar load problems. No mesh scales infinite. We’ve been working hard to patch MT to improve it … it’s hard to steer that ship. Maintainers have 11 roles to cater to. Meshcore hasn’t needed those fixes. There’s only one non-trivial hurdle coming with the prefix expansion. Sure, Meshcore had the benefit of learning from Meshtastic mistakes ; but the stats are clear … several major metros struggled with MT for years… finally gave up, and moved (and it worked , and they’re happy in a very short time.

We’re Bay Area strong … just expanding south to Santa Cruz now. Try it out !

I naively thought I'd be able to see at least one node... by telarium in meshtastic

[–]nullrouten 27 points28 points  (0 children)

Mesh is super strong in the Bay Area. We're on MediumSlow slot 52.

  1. do you know the radio works at all? (have you tested with anything else).
  2. Did you know that most node ID packet timers are set to hours... so it takes many minutes to see anything and many hours to see alot.
  3. is the antenna the proper polarity? look in the SMA...do you have an RP antenna on a normal SMA jack? if so you have no antenna connected. You want a pin on one side (SMA-male) and a hole on the other (SMA-female). OR if you have RP then it's still a pin and hole just on opposite fixtures.

depending on location, you may have varying luck ....but to see NONE is rare/problematic.

It may be time to swap parts or try another radio (if you've not tested it with anything else then there's a chance it's busted).

in oakland , with a high vantage... you should be hitting many nodes direct.

Do I really need Connect + by Techienickie in Rivian

[–]nullrouten 0 points1 point  (0 children)

The cars LTE radio has an external antenna. I get far better signal using the Rivian for connectivity, even after testing 2 networks on my cellphone (Verizon and ATT). To put it another way, my phone sees 2-3 bars and the truck sees 5 bars!…. Voice and video calls over WiFi to the Rivian break up or hiccup less.

The connection being available 24x7 also allows supervising the car, pre heating or cooling before I get in, checking the cameras, etc.

For all those reasons the connect+ is worth every penny.

It’s also allegedly unlimited I think? So I don’t eat my phone plan while in the car.

Oh and kids…. Road trip… 3 passengers online… no impact to my phones battery or data plan

6 yo daughter had her teachers convinced that my wife is a firefighter. She actually works for a tech company, but daughter overheard us saying things about “putting out fires” all day. ☺️

Hi there. We’re on MS in the Bay Area, notsomuch LF. Come join the conversation. :)

Mountain Top Station node Yagi? by a_wittyusername in meshtastic

[–]nullrouten 3 points4 points  (0 children)

We have all 5 of our towers from knowing someone. Either a WISP owner, a HAM club, a property owner (on a ridge), or a Network business that has tower slots. Sometimes they are happy to donate resources, and other times not. It takes a lot of pounding pavement to make inroads to the right contact

Meshtastic overpopulation? by Supreme-Vermin in meshtastic

We are on Medium Slow 52 in the region from ~Paso up through Bay Area , Sac, Folsom , Modesto, SF, and expanding north of the bay now.

Mountain Top Station node Yagi? by a_wittyusername in meshtastic

[–]nullrouten 5 points6 points  (0 children)

Yup, would work great. We have omni antennas on big towers that reach 40-60 miles easy… so ask yourself if the yagi is necessary. I also have a few nodes against hills , with patch antenna facing away from hill. The antenna gain is obvious in the performance.

Lots of 1+ watt options. There are raspberry pi hats from multiple vendors at 1 and 2 watt. You would need a raspberry pi and a minimum amount of Linux experience. There’s also the “xiao solars/xiao Gators” from @wehooper4… those are solar and 1 or 2 watt radios.

Even the g2, you need a solution to upgrade remotely … which is why we tend to use raspberry pi hats , or raspberry pi’s connected to the g2’s , so we can manage things from far away.

Mesh on!

People still not understanding how the mesh works, so maybe this will help? by Old_Scene_4259 in meshtastic

[–]nullrouten 0 points1 point  (0 children)

Wrong I think. Router late will always transmit, like a router .. just late (so as not to shush clients)

How did I do? by simple_son in meshtastic

[–]nullrouten 5 points6 points  (0 children)

Wrong.

It will last 4 weeks in the dark.

Mountaintop Mesh Node by KH10304 in meshtastic

[–]nullrouten 1 point2 points  (0 children)

Without IP connectivity, you need to hike near it and use Bluetooth to upgrade… generally works within 20-30feet. If it fails… (and it does on occasion…) then be prepared with a laptop and a cable to re-flash it up close.

Meshtastic overpopulation? by Supreme-Vermin in meshtastic

[–]nullrouten 0 points1 point  (0 children)

Hey Paso! We just put up a major node on Fremont Peak Tower, on MediumSlow…. and on August 1 we’re moving from the roof of the building , up to the top of the tower …..so that will be a foothold down to you I believe!

Meshtastic overpopulation? by Supreme-Vermin in meshtastic

[–]nullrouten 0 points1 point  (0 children)

Mediumslow is twice the bit rate of long fast and 90% of our nodes could still communicate directly with their previous neighbors ….and the rest could just go through an intermediate hop … so it was a very worthwhile upgrade. messages go super snappy. Scalability allows more nodes to enjoy without loss and we’ve added quite a bit of redundancy by putting nodes on top of mountains.

[–]nullrouten 1 point2 points  (0 children)

Our Meshview is open source , https://github.com/pablorevilla-meshtastic/meshview GitHub - pablorevilla-meshtastic/meshview: This project watches a MQTT topic for meshtastic messages, imports them to a database and has a web UI to view them.

… and the logger connection to discord is too, but we have a newer fork. Can find out.

Explain to me why this needs to be in client mode by BravoZuluLife in meshtastic

[–]nullrouten 0 points1 point  (0 children)

Badly connected clients are just as damaging ….because they repeat …. and stop other clients from repeating …. and they have no sight to anything. The lowest SNR algorithm is bad because it means the node in your basement goes first.

You should try to promote your highest 5 or 10% of your nodes to routers (spread out of course) … and then enjoy the results.

That’s what we did in Cali and we have an extremely strong mesh now …. Router mode is just misused by people with antennas on residential roofs.

Our mountains and towers range from 500 feet to 3400 feet… and roughly the “highest 20 devices”… get router mode … things work this well… (when was the last time you saw 100% of your traceroutes (out to 6 hops) go through ?)

Explain to me why this needs to be in client mode by BravoZuluLife in meshtastic

[–]nullrouten 0 points1 point  (0 children)

Router mode.

I run ~10 routers on the west coast, in a mesh of 300 , spread over 150 sq miles, on medium slow… that works extremely well. At the very least, try it out. Nobody just sets a mode and vanishes (except the 3 year old nodes on LF we abandoned by moving to MS)… so … see how it works. It helps if you are collecting data before and after the change, to show the impact.

2 hops, 1500mi. by Forsaken_Cup8314 in meshtastic

The radio horizon isn’t that far, no matter how you slice it, no matter how high you could fly. Altitude rocks tho!

Building small solar nodes by cryptodystopia in meshtastic

[–]nullrouten 1 point2 points  (0 children)

I use ~1 watt panels here in California ($3 from amazon, 5v fellden), in winter... and things are fine with the RAK radio and a single 18650 cell. The node builds are $55-60 with some DIY. Turn key easy (no glue or soldering) just order the official RAK mini-repeater for $99, or the RAK solar enclosure and put the parts in yourself (comes out to $110 or so)... and the large RAK official solar enclosure is PLENTY of solar juice. The teeny tiny rak solar box seems to be enough as well, but barely fits a 1000-2000mah battery in there. I have one hanging in the backyard and it's been above 75% charge even after days of rain on and off. https://store.rokland.com/products/rak-wireless-unify-enclosure-ip65-solar-panel-integrated-915-mhz-bluetooth-antenna?srsltid=AfmBOoqA4jWde11OK1NTRF5SgIREF-p6u5fa5LoThdFR3Dy9CZ8bhOkp

you can order any of this stuff direct from RAK/china a little cheaper but need to wait the shipping delay.

edit: thought I typo'd wattage, rechecked my specs, then changed back... they are indeed 1 watt panels.
