Sorry missed a bit
I'll try that enclosure you suggest - its a good
price. But I'm
wondering, have you tried using one of them
with the other parts in that part list?
Yes I pulled together that list. You could get a better quality
antenna if you're willing to research/spend a bit more.
How did you handle mounting to and getting the aerial
out,
I used the existing holes and cable glands.
Are those connectors the right size for that, without looking in
detail at the components I'm guessing it would want the small
connectors for the solar panel cable but its unclear if the 4-8 or
9-12 connector would be best for the antenna proposed - I think the
smaller (the antenna says 8mm)
Yes the smaller cable glands are what I used.
There are certainly other ways of doing it, the motivation for that
list was a zero-solder kit as many don't have a soldering iron.
If you are using that list then ask the MPPT guy (I forget his name)
to solder on the screw connectors for you.
The MPPT/ LiPO4 is not the cheapest route but is the least likely to
catch fire IMHO.
AFAIK DR is less power efficient than Meshtastic but does scale
better. Meshtastic is limited to three hops I think, and a max of 30
users. I believe LoraLayer2/ DR can do better than that, but I'm not
sure if anyone has actually tested a network that large.
Thanks

Yes, I meant the one on the video.
3D printing is a totally fine way of doing an enclosure in low
volumes, but is a massive difference in both reality and "cost"
between buying something on Alibaba or just via paypal from someone
who has built them before, and something only available as a CAD/3D
printer file. I've gone through the process of finding a 3D printing
shop, and getting something made, with a less than 50% success rate,
and a one-off is always more expensive as even a good shop has to
allow for the likely cost of getting it wrong the first time.
One of the advantages disaster.radio potentially has over some of
the other solutions its the potential for geek-free setup and
install. I can figure it out, but most of the villages around here -
who could use a setup like disaster radio - don't have a resident
geek, and trying to find a 3D printer to print a one-off certainly
puts it in the needs-a-geek bucket.
The enclosure Sam suggests sounds a better candidate, though it
needs the panel mounted separately.

If you mean the one featured in the video, you're free to make them
yourself. The design exists as CAD and in 3d printable formats in
the github repository. It is not less "real" simply because it
hasn't been mass produced.
Otherwise, like we've suggested, you can follow the Aliexpress
parts list and make a working device, or use any enclosure designed
to prevent water ingress.

Thanks Sam
I was looking at the enclosure shown on the image on
https://disaster.radio/ and thought that might have been real :-(

Can you clarify what the current state is - i.e. if I got
the boards, built a pair of units, and flashed it - then
would the chat and map apps talk over it.
Yes that should be possible. You can buy them pre-flashed if
you want to miss that step:
https://www.aliexpress.com/item/4000396836096.html
If using the webapp you only get a chat.
If you use the Android app then you get a chat and a map AFAIK.
By the way ... I notice there is a bad link to the
enclosure on https://disaster.radio/build/
Thx started fixing that link here:
https://github.com/sudomesh/disaster-radio-website/pull/12
awaiting someone to approve.
This was the enclosure used:
https://www.aliexpress.com/item/4000452268197.html
It's fairly obvious how to put it together, but there are some
instructions here too:

I've been spending my free time trying to modify the
firmware for the v3 dual-module prototype, it is
slow-going.
Other LoRa boards seem to work pretty well with the
firmware in its current state

I tried to find out what was happening with
Disaster Radio, by
asking here - got zero responses :-( its really
hard to figure out
if there is anything going on that is useful to
connect with :-(

Hi,active list?Grzegorz
Sort of. When people ask, someone answers.
But not much seems to be
happening. I do have the impression that those
on the list wish there'd
be more activity, and that most of them sort of
hope to contribute. I
of course do not speak for the coalition.
Perhaps you can tell us why you're interested
and what you'd like to see
as highest priority.
