I had a set of headphones that took a dump so I looked at the wire and began to have thoughts.
it's about 2.5 mm in diameter and about 3' long. So I cut a piece about 3/4" long and pulled out the wire. My first try was to cut a couple small sections of a straight pin and shove them in the ends then mount it to my project. Because it had no structure, the ends got a little screwy and didnt seat right. Then it occurred to me what I had to do
I needed to run the pin entirely thru the wire housing. This way i can have any kind of bend that is needed and due to the rigid nature of the straight pin, it will stay where I put it.
shown here in place with a couple crimps i picked up in the jewelry making aisle at Wally World.
This wire looks like rubber and I have enough for a lifetime of building.
Thanks for looking
