About a year back I stumbled across these cool products that are a heatshrink sheath with a metal ring coated in low temp solder inside. They made all of my wire joining a million times easier. Just strip the end of two wires, push them into the sheath and blast them with a heat gun for 20 seconds until the ring contracts into a crimp and the solder flows onto the wires. Better physical and electrical connection than a crimp, with none of the futzing that comes with soldering and sheathing.

Thank you for sharing, this looks awesome! Will have to look into getting some.
