I have a signal cable (also transmits power) that is extremely short (see attached picture).
I would like to extend the cable with one meter (3ft), and I was thinking of cutting it in two (again see picture), and then attaching it to either a phone cable or a flat console (serial) cable, but I don't know how to best attach the cables.
How do I attach thin twisted cables so that I can extend my signal cable?
Edit: I have tried different ways of extending and done extensive testing that the signal survives (it does). However, none are good "permanent" solutions. The signal is 9600 baud, and the device draws minimal amounts (<1W) of power.
