I brought my “Arduino on the go” along to New Mexico, but discovered I’d installed a pushbutton on the breadboard in a spot that was already wired to ground, making the button always “pressed.” In order to move it, I needed more jumper wires; and due to a combination of hurry and hubris, I had brought none along.
I needed some 24- to 26-gauge solid wire, in a cabin, on a mountain (excavaaaaaating for a mine). The nearest Radio Shack was twenty miles and about forty minutes away, and I couldn’t think of any store in Angel Fire likely to have wire for me.
So, where would you scrounge up wire in an emergency? I’m actually interested in suggestions — add them to the comments if you can come up with something other than my ideas. I didn’t have anything along that I could take apart for wire, I didn’t have a soldering iron to tin stranded wire, and I wasn’t willing to damage anything in the cabin, the car, or the area.
