Incidentally. I bought a box of the wrong size JSTs so I have a bunch to practice on and ruin. My project needs 1mm/1.5mm ZH/SH connectors and 2.54 for standard pcb/breadboard connections. These 2mm PH are no immediate use so gonna make a bunch of useless practice cables.

Aside: pre-crimped wires are a thing and that’s what I plan to use where possible. I need to learn manual process though, to do some components that came with uncrimped wires already attached.

This is my wax-on/wax-off plan as well.

Man, I just got into building speakers which requires endless stripping and crimping and I hated it so much. So I just made myself do 100x strip and crimps and taught my hands to do it (hat tip @visakanv). Now it just happens without me thinking about it.

Kinda hacked it by recrimping using the 24 AWG die even though I’m using 22 AWG wire. The connector can handle 22-28 supposedly but since 22 is the biggest maybe it’s harder?

The hardest part of this is not knowing whether I'm doing something wrong, or whether the tool or materials are wrong. Gonna have to try a couple more times with variations to see if I can get one to go exactly right. Filming me doing the actual crimping will be tough.

All my crimps are bad. Gonna have to practice a few dozen times I suspect, before I get the first perfect crimp.

It’s a delicate, irreversible operation the wire goes between the wings. Bare in the middle, insulation into larger outer wings. Regular and microscope views.

Screwed up another pair. In first I’ve pushed the insulated part in too far. Second, strands are loose from bare crimp part. Didn’t screw up the lock tab at least. Still doesn’t fit housing right. grrrr. Giving up for the day.
