Could it be that we go to the hardware store, pick up a spool of copper wire, get some wire cutters, a little clip-clip, saw it all up and then, bam—we have our printed circuit board?
And we made some printed circuit boards, and we sold some to our friends, and I was trying to sell the rest of them so we can get micro bus and calculator back.
Eh, I sold my Volkswagen bus and Steve sold his calculator, we got enough money to pay a friend of us to make the art work to make a printed circuit board.
A different sort of pay dirt, however, offers the prospect of a much greater return for urban miners: the printed circuit boards (PCBs) found in rapidly growing mountains of electronic waste.
Here we have these 32 wires that are routed along the edge of the printed circuit board and connected to a flat cable that goes to the touchscreen display.
Inside this mouse is a rather complicated printed circuit board or PCB, and without it, there would be a rather messy jumble of wires that most likely wouldn't even work properly.
