Hi,
When I started with home automation in 2020, I’d never soldered my life and it was quiet a learning curve. For many years, I could not make Dupont connectors though not for lack of trying so I ordered few types of jumper cables in bulk on AliExpress and would cut them as needed.
I recently stumbled upon this amazing video that explains how to make Dupont connectors and I got my first one right!!

This is not my project and the credit goes to the author of this video!
Hope this video helps anyone who has struggled (like me) to make good Dupont connectors.
