What you carry around in a tool bag is always very personal.
What other people carry around is a great learning opportunity, especially when they have put in self-made or self-assembled tools.

Gelukkig heeft de Nederlandse pagina Koperdraad: Gegevens – Wikipedia deze tabel (let op weerstand is per 100m!)¹

An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices
Via [Wayback/Archive] @jilles_com@infosec.exchange on Twitter: “Will be taking to meshtastic.org Lora 433MHz modules to @hotelhacker. Might be cool if more people could bring some to setup a larger mesh and play with them. amzn.eu/d/aCgULy4“
Products:
For both boards, this holds:
1. The Meshtastic program is not pre-installed on this product. If you need to install, please check the steps:
github.com/geeksville/Meshtastic-Android/blob/master/README.md
github.com/meshtastic/meshtastic-device/releases
2. If GPS does not work, the following situations may occur:
Install the Meshtastic firmware before and now reset the GPS when you switch to another firmware.
Reset steps: github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test
3. If GPS is weak indoors, it can be used outdoors
4. The GPS antenna is not installed stably, you can check if the interface is attached to the GPS antenna

[WaybackSave/Archive] GitHub – RfidResearchGroup/ChameleonUltra: The new generation chameleon based on NRF52840 makes the performance of card emulation more stable. And gave the chameleon the ability to read, write, and decrypt cards.

It is also available from various Asian sites.

Way more lightweight than Flipper Zero (less chance of getting it confiscated at border controls as well) but also less powerful/flexible.
