LEMO connectors are cool, but there are some really interesting and unusual connectors in the military like the hermaphroditic (left) and rotationally-symmetric-magnetic (right) connectors. The former is where there is no concept of socket/plug, it's completely genderless. The advantage is that you have single PN# and they can be easily daisy chained for extension. The latter has concentric pins, goes any-which-way like USB-C but rotationally invariant over 360 deg.

The nightly version of the SatsDecoder software has a nice new feature. It can create graphs from telemetry data. Thanks Alexander @Baskiton!

Kanopus-V6 * 13 lug 2026 * max el. 70° est
I’ve found a way to receive KAN here in central Italy during passes with elevations above 50° by positioning myself on the satellite's descent path, past the zenith, so I can wait for them to switch it on. 😀

Finally at the point where I feel good enough to release my LORA Project:

-Decodes Meshtastic, Meshcore, LoraWAN, and other protocols.
-Detects on non-standard frequencies across the entire bandwidth.
-Supports Soapy, BladeRF, and USRP
-Add custom keys

Open-source firmware for off-grid communication on ESP32 handheld devices.

Trail Mate leverages existing projects like Meshtastic and Meshcore to provide off-grid communication and GPS sharing using a simpler user interface with a GPS map and a chat window.

It also implements features like a GNSS Sky Plot, SSVT image transfer, and Team Mode using ESP-NOW + LoRa. Several devices from @lilygo9, @M5Stack, and GAT IoT are currently supported or under development.

GPSモジュールで取得した現在位置を中心として、周辺の飛行機をレーダー風に表示できた。飛行機の信号も、家の中より車内の方が良く受信できてる。
