"dirtbikes, or chainsaws typically do not have microchips" Interesting, good examples. "The wetter the clothes, the more power the heating coils will draw through the resistor, which lowers the voltage of the power the timer motor receives, slowing it down. Once the clothes start getting dry, the voltage goes back up and the timer speeds up again." Sounds like this kind of ingenuity is on its way out, though. I expect the vast majority of washers/dryers have semiconductors in today.
