-rant- chinesium wires
artag:
If I'm stuck for something better and have to use the cheap dupont wires, soldered, I leave the dupont pins in place and solder to them instead of the wire. It's a bit clunky but you do get a bit of strain relief too.
Smokey:
Interesting. I've never heard those jumper wires called "DuPont wire" before.

Where did you buy these? Local or from China? My experience is that the stuff you source from China directly (through Aliexpress, Amazon, Ebay) is of higher quality compared to Chinese stuff you buy locally.

i think amazon. they were part of one of those breadboard + wires package. mle-male , male-female, female-female wires. come as a multicolor ribbon cable. you rip them apart.

those sellers of aluminum wire don't want us to have the technological edge by actually being able to plug in components

And once you get it.. strip the wire, put an exactoknife into a wirestrand (hopefully solid wire), and double-check if its copper all around (and inside).

Then you may run into another monstrosity, CCC, which is copper-clad-copper. Specifically a thin plating of copper over whatever random gunk was being brewed up at the smelter that morning, with at least some of it being copper so it's hard to tell whether it's proper copper or CCC copper. In that case you need to run resistance measurements to see whether it's proper copper or not.
