Posted by jpluimers on 2025/12/17

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.

So thanks Clive for releasing this very personal video: [Wayback/Archive] Big Clive: Lighting tech tool bag tour 2025 – YouTube

Weerstand van koperdraad – Koperdraad: Gegevens – Wikipedia

Posted by jpluimers on 2025/12/02

Voor warmteontwikkeling in koperkabel was ik benieuwd wat de weerstand voor diverse diameters was.

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

Interesting; Meshtastic

Posted by jpluimers on 2025/11/27

ImageOn my list of hardware/software to experiment with is [Wayback/Archive] Meshtastic:

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

It is also available from various Asian sites.

Query: [Wayback/Archive] chameleon nfc reader writer at DuckDuckGo

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