Bundling DuPont connectors: 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube

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:

More Apple ][*, //* II* and classic Macintosh hardware upgrades

Posted by jpluimers on 2025/11/14

The mini micro classic Apple emulators related post last week became way too big, so here is the classic Apple 2/Macintosh hardware upgrade part follow-up I announced in Some notes on mini/micro Apple //e emulators.

Last week, I mentioned [Wayback/Archive] ARC Javmaster – YouTube. Let’s continue from there for an even bigger post (:

Javmaster actually has a shop at [Wayback/Archive] Welcome to the 8-bit stuff store – 8 bit stuff cool retro computer 3D gadgets and geekery with a lot of interesting (mainly Apple ][ era related) retro things like:

Some notes on mini/micro Apple //e emulators

Posted by jpluimers on 2025/01/30

Retro computing is wildly popular, and with the rise of low cost single-board computers (SBCs for short), both Apple //e and ][+ emulators plus extension cards have proliferated,  based on Raspberry Pi (or even their RP2040 microcontroller based Pico), ESP32 or predecessor ESP8266 microcontrollers and others.

Some links for my archive:
