Step 1: Rip the End Off the Cable
I just yanked the plug off and exposed the end of the inner wires by stripping a quarter inch off each end with my thumbnail.
Basically grip the nail where you want to strip, bend the cable over the back of the nail, press your nail down hard and pull the cable.

Step 2: Eh What Now?
However that gave me the notion of making the male plug a female plug for this purpose, yes this instructable has forever muddied the waters of robot and computer sexuality, at least it’ll slow down the terminators…
So get a bit of paper…
Step 3: Dots.
Hold the USB plug down and draw two dots marking the outer two pins, if they’re facing upwards ground is left and +5V is right
Step 4: Holes.
Poke two holes in the paper with a pen, slide the wires through a little so they lay flat on the back with just the exposed copper showing.
Step 5: Folding.
Fold the paper over backwards and then over a few times to create a rough shape, it just needs to be fat enough to hold the exposed wires against the pins.
Step 6: Squeezing It In.
This is mildly tricky, you’ve got to shimmy the paper in at an angle to start with so the contacts don’t just get pushed away from the back of the paper, also you may need to squeeze it in at the sides, bend any excess paper upwards to ensure that it doesn’t interfere with the contacts.
Step 7: Success…
It worked first time, which was a shock, a really big shock. This seems like it needs refined and learned, not just thought up
