As you can see by the photos, I took a broken and otherwise useless magsafe end and made a splice. After a resolder, the LED shows the computer charging.

This is the hyper extended end of a magsafe. It is no longer working due to the frayed wire having pulled apart.
Use wire cutters to cut the wire of the magsafe some distance back from the manetic end. I used about 4 inches but in reality you can get much closer like maybe an inch, as you will see in the next step.
I used a Stanley knife to cut the nice white cover off the tiny printed circuit board. There is a molded plastic cover similar to hot glue or RTV sealer which had to be stripped off the PCB.
1.) Take the good end of the existing wire and strip it.
2.) The interior wire, which is coated in white should be soldered on a square metal plate about one eighth inch square. This plate is opposite a small chip for reference.
3.) The braided wire coats the white interior wire, and is wrapped around it in two different directions. This wire should be peeled off and then twisted together.
4.) Then solder it in place opposite the chip and the other wire.
