    [synopsis] => Test the limits of small, inexpensive, off-the-shelf hobby motors by building a motor-driven crane capable of lifting 100 pounds - a tall order for a motor that weighs only a few ounces! First, construct the world's simplest electric motor to gain insights about how they work. Then calculate the torque requirements for your crane, and add gears and pulleys to achieve mechanical advantage.
