No Meshcore in Vail?
. I spent several hours yesterday in Vail, Colorado. During this time I tried again and again to reach a repeater in Vail. I received no adverts from any Meshcore devices, and in particular received no adverts from any Meshcore repeaters.
As far as I was able to see, there is no Meshcore activity in Vail.
Are you aware of Meshcore activity in Vail? Please post a comment below.

Avoiding ruining a Harbor Breeze solar repeater in winter
click to enlarge A few weeks ago I learned about, and got energetic about, the Harbor Breeze solar repeater hack. I have by now constructed several Harbor Breeze (“HB”) repeaters using the RAK4631 WisBlock Kit (blog article) and several more using the Seeed Xiao nRF52840 & Wio-SX1262 Kit (blog article). But I am in the northern hemisphere, and it has been above freezing this whole time.
I now realize I need to worry about the fact that Winter Is Coming. It seems that almost everyone except me already knew that (a) it will supposedly ruin a lithium-ion battery if you try to charge it at a temperature that is below freezing, and (b) very few of the commonly used chips for charging control provide standalone protection against trying to charge when the temperature is below freezing.
In this blog article I try to set forth the nature and magnitude of the problem and possible workarounds. (more…)

Seeed uses really good batteries in its SenseCAP Solar Node P1-Pro repeater
click to enlarge In an earlier blog article I described my worry that one of my four Seed SenseCAP Solar Node P1-Pro repeaters (seen at right, at an elevation of around 10000 feet or around 3000 meters) might have power problems. I worried that maybe the batteries were no good, or that the solar panel was weak, or that the charging controller was not doing its job right. I had to hike up to the remote location of this repeater and swap it out with a spare.
I have now had an opportunity to do testing on the ailing repeater. A first bit of good news is that with some simple charge-cycling, the repeater now has no difficulty charging fully. And a second bit of good news, as I discuss here, I have learned that Seeed uses really good batteries in this repeater. (more…)

Using a Seeed controller in your Harbor Breeze repeater hack
click to enlarge Anybody who gets involved in setting up a LoRa mesh network (for example Meshtastic or Meshcore) eventually encounters the Harbor Breeze Solar Light Enclosure Hack. The hack is that you go to Lowes, purchase a 60-lumen solar powered outdoor light for $10, discard most of it, and add a LoRa mesh controller and antenna. The result (blog article) is a relatively inexpensive LoRa mesh repeater seen at right. The original hack uses a RAK WisBlock controller (RAK link, Rokland link, Amazon link) that costs around $32. In this article I describe how to do the hack using a Seeed Wio controller (Seeed link, Amazon link) that costs around $14 when purchased from Seeed. (more…)
