One moment playing with LoRa. Next, a Nintendo Switch controller to fixed.
LoRa Antenna measurements
Using my NanoVNA and a RF test Kit I learned something about measuring antenna.
Below a measurement of a unknown antenna, ITs off, I need to shorten the metal spring inside.
UPDATE : 20260126
I’ve been playing with LoRa for some time now, mostly with two adhoc LilyGO nodes.
After seeing a YT clip from Andreas Spiess I installed a meshtastic node on a Heltec V3.
Wanting more, I bought a Heltec V4 and an 8DBi (60cm) antenna.
Heltec V3 got a new home in Tyrone’s home.
Via meshtastic I communicated with a guy here in the neighbourhood.
I installed Meshcore and my LoRa playground grew!
A Nebra Helium Miner was bought, and repurposed !
There is a Raspberry CM3 in there (Compute module)
Some big antenna’s and a waterproof case.
Using POE to power the thing, the plan is to have this installation at a high point around my house. (LED pole?!? 🙂 )
Meanwhile I got these : Seeed Xiao Lora ESP32 modules
MeshTUI
My mobile Heltec V4, big antenna coming and battery operated, so I can add to https://mapme.sh
