    Freaduino UNO Rev2.2 MB_EFUNO

    Leonardo da Vinci improved upon the already-established catapult design when he introduced his own vision of the age-old military launching device. This design uses a double leaf spring to produce a great deal of energy in order to propel stone projectiles or flammable materials over large distances. A hand crank on the side of the catapult was used to load the spring.
