one issue I see is it needs to be placed so that the solar is facing up which then makes your antenna horizontal when you really want it vertical.

Be sure to connect the antennas before connecting the battery and then solar panel to avoid damage to the transmitters. I like that most of your bill of materials is from Amazon. I'm building a similar solar powered Meshtastic network with three nodes for family SHTF comms. I'm using a much larger 6W solar panel and three 18650 batteries per node to prevent brownouts that would require access to reboot it. I'm using 8.5 dBi antennas which are hopefully overkill but I've had too many low power comms projects where I wished I'd used better antennas. No GPS as I know where they are, but a temperature and humidity sensor in case I need to do some troubleshooting before climbing onto the roof. I'm designing and 3D printing the enclosures to fit the 45 degree solar panel, large antenna, battery box and PVC pole mount. It's a fun project, and based on the deteriorating state of the world, it may be very useful soon.

Cool video, thanks for sharing. I have two questions though. 1- What is the lifetime of a fully charged battery? 2- Have you tried the edge case in which the repeater runs out of battery, and then gets charged again by the solar panel. Is the device restarting automatically?

check out our explanation on austinmesh.org - we found the design in this video will NOT reset itself once the battery runs down to 0. We now use a Voltaic battery pack with a 6-12 watt solar panel - everything is USB connected. The newer design will reboot itself when the battery dies and the sun comes back.

As it's possible to set a static location in meshtastic, it would save power vs running a GPS module. Any idea if traceroute and other distance info would work on nodes with a static/fixed GPS location?

yeah exactly - no need to use the GPS module for repeaters - we don't add these modules to repeaters any more. Just set the location as fixed with the app when you install the repeater.

Yeah this one was a 3db. I've got a whole drawer full of 900 mhz antennas of different sizes because a friend of mine who was into helium donated a bunch. We're using a 10DB on top of one of the UT buildings and a 5.8 DB on top of the high school. The one here is 3 DB. Check out the meshtastic documentation for antenna SWR results.

So what is or are the EMP protection possibilities for this little monster?
@teamlieblong
6 ай бұрын
EMP resistance would require either a faraday cage/bag around the entire device and the antenna which would block all signals making the device useless, or some ground shunting device. The real world EMP protection is to build a few of these and put them in an EMP container (just the devices no need to put disconnected antennas in there) and if SHTF go replace the devices that got fried with your backups.
@austinmesh
4 ай бұрын
I've thought about this a little bit - you could make these things EMP proof by putting the whole system inside of a steel enclosure. Then the only things you need to worry about are the two inputs into the box: the antenna and the solar panel. Each one is really just two wires. You could add Self Resetting Fuses on those 4 wires and if an EMP happened it would just trip those fuses and then a minute later they would re-connect and theoretically the whole thing would work. Would love someone to set one of those up.

@@austinmesh it's on the to do list for sure! I've talked to a few ham radio enthusiasts about this. And collectively they agreed that a faraday around the "body" with high reaction fuses with shunting capacitors for the antenna and solar. But the capacitors will interfere with the Rf signal especially with high encryption requirements. So I'm told.
