I'm not very good at electrical technical terms, but I wonder what he marinates his inductance in?
Anyway, good for him for DIYing his own cables, and very neatly too, it looks nice. There are plaits for any number of components. investigate plaits or sinnets, if not on the net, then in a really good book about old-fashioned knots and rope work for sailors.
However... in cat5 cable (and probably later specifications too) there is a prescribed pitch and pattern to the twist. I learnt this from a cabling engineer, who was explaining to me that that was why he was carefully keeping that pattern in place right up to the very termination in the patch panel. It wasn't just for looks, it was for specification too: it would not have been cat 5 cabling if he hadn't!
NetFreak probably knows if this applies to other digital cables.
