The Da Vinci Rolling Ball Timer kit was inspired by a sketch of
an escapement mechanism drawn by Leonardo da Vinci. Using the
laws of motion and the concepts of gravity and kinetics to
measure the passage of time. The mechanism employs precision
gears to power a moving platform which in turn propels a rolling
ball. Timing speed is controlled by adjusting the weight and
balance of the gear-propelled armature. The reciprocating
movement keeps the ball in motion.

Leonardo da Vinci was an Italian painter, sculptor, architect,
musician, scientist, mathematician, engineer, inventor,
anatomist, geologist, botanist and writer. Leonardo has often
been described as the archetype of the Renaissance man, a man
whose unquenchable curiosity was equaled only by his powers of
invention. He is widely considered to be one of the greatest
painters of all time and perhaps the most diversely talented
person ever to have lived.
