Bundling DuPont connectors: 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube
Posted by jpluimers on 2026/01/15
Nice idea: [Wayback/Archive] 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube
It mentions DuPont wire connectors which is colloquial for a common form of jump wires: the ones that can connect to breadboards, or male or female pin headers. Basically a so called “DuPont wire” is an electric wire with a pin header (either male or female) on each end leading to 3 kinds (not counting ones having multiple connectors on each wire) as male – female is the same as male – female:
- female – female
- female – male
- male – male
Being able to group the connector end of multiple jump wires in one enclosing connector for quick opening and closing is a great idea.
Hopefully the 3D printing files will be released somewhere.
One of the comments is also inspiration for a future 3D printing project:

The algorithm got me to the first video of this list: [Wayback/Archive] pierogi engineering – YouTube – search – hard drive
It’s similar to a longer second video that also does balancing using the gyroscopic effect of the moving platters.
Nice!

Big Clive: Lighting tech tool bag tour 2025 – YouTube
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

A ton of keyboard conversions via GitHub – trekawek/mac-plus-ps2: Arduino project that allows to connect a PS2 keyboard to Macintosh Plus
Posted by jpluimers on 2025/12/12
This is for earliest compact Apple Macintosh systems predating the introduction ADB (Apple Desktop Bus) on Macintosh SE and Apple Macintosh II (and Apple IIgs which technically is not a Macintosh):

Before continuing to an even more impressive keyboard and mouse interfacing project below (basically many kinds of modern keyboard, mice and gamepads to many retro computers) that I found thanks to doing some more research after finding the above one, lets summarise where the above one is still useful for:

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
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:
- 433Mhz: [Wayback/Archive] LILYGO LORA32 T-Beam ESP32 Development Board WiFi BLE CH9102F Chip TTGO OLED Module Meshtastic Motherboards: Amazon.de: Computer & Accessories
- 866/915 Mhz: [Wayback/Archive] LILYGO T-Beam LORA32 ESP32 Development Board WiFi BLE CH9102F Chip Meshtastic TTGO Mainboards Soldered OLED Module: Amazon.de: Computer & Accessories
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
