> or you spend twenty hours soldering nearly microscopic bits of magnet wire to it. A real chip would only need two or three contacts to vastly outperform thing demonstrated here. These would probably not be soldered, they would ideally be bonded directly to the chip. Imagine a near-microscopic 4-ball BGA on a bit of flexible PCB, except the PCB material can flex in multiple axes simultaneously.
