In the past, I have complained bitterly about the difficulty of getting reliable cables for Apple computers, and also about how ridiculously overpriced they all are. I may have been wrong. There’s a good reason for that.
Adam Savage takes apart several USB-C cables, from a $3 cheapie to a $10 Amazon to a $130 (!!!!!) official Apple cable, and I learned something new.
Whoa…those expensive cables are packed full of complex circuitry, which I did not expect. Back in the day, I used to make custom RS-232 cable all the time — cut open the cable, splay out all the little wires, solder them to the appropriate pin in the connector, and you were done. That’s all it was, was a wire-to-wire connection between two adapters. I don’t think I could make a USB cable, and it’s not only the teeny-tiny wires that would exceed my soldering ability, but I wouldn’t be able to cope with all the miniature ICs in there.
