22,00 €On page 945/r/ of the Codex Atlanticus, Leonardo da Vinci drew many devices for the plan of a mechanical paddle boat. One or more sailors can alternate working the pedals. The pedals transfer the alternate motion to a central gear, where it becomes linear motion, and a series of gears transfer it to the two big paddles on the sides of the craft. The central gear is drawn in more accurately on another page, 30/v/, and the mechanism works through springs hidden in the two main wheels that alternate. Per saperne di più -
18,00 €The ornithopter is a machine designed to fly by the flapping of its wings in imitation of birds.In 1485, Leonardo da Vinci began to study the flight of birds. He grasped that humans are too heavy, and not strong enough, to fly using wings simply attached to the arms. Therefore he sketched a device in which the aviator lies down on a plank and works two large, membranous wings using hand levers, foot pedals, and a system of pulleys. Per saperne di più -

22,00 €PRM booklet not included from september 2013 This model represents one of Leonardo da Vinci's most intriguing designs. It has been known as "Leonardo's Automobile" but recent studies consider it one of the first robots in history. The machine is drawn on folio 812/r/ of the Codex Atlanticus together with other devices. The robot's engine is hidden internally: a spring held fast by a stopping mechanism trasmits motion to the gears that move the wheels on the sides. Per saperne di più -

19,00 €Helicopter Leonardo da Vinci Italeri This machine, which is considered the ancestor of the modern helicopter,appears in a drawing dated roughly 1480 contained in theCodex Atlanticus. Leonardo outlines the plan for an “aerial screw”imagining it as a worm screw with a diameter of approximately 5metres, in his intentions, it should have “screwed itself” in air takingadvantage of its density. Moved by the muscle strength of four menwalking on the central platform, it consisted of a wooden structurecovered with starched linen cloth. Since there is no proof that Leonardoactually built the machine he imagined, it remains one of hismany theoretical insights. Per saperne di più -

The first page of Leonardo's Codex Atlanticus shows a mysterious drawing. Analyzing its details, we discover that it is a circular mechanism with sixteen radial guns. The central mechanism looks like a boat moved by a double paddle. This secret weapon could be a circular warship that could rotate and fire in a 360 degree arc. The central gear wheels allowed for independent movement of the two mechanical paddles. If while firing the ship rotates, the crew can open, clean and reload the gun that is quickly ready to fire again. A round shield can protect the vessel, making it a warship with 18 bombards.

22,00 €That genius of Leonardo Da Vinci doesn’t need any presentation. All his inventions and ideas written by him in the Atlantic Code were in many senses forefront. Many of these, that today we take for granted, are based on its thoughts and visions. Regarding the clock, Leonardo da Vinci wasn’t the inventor, he only improved it. The clock have two separated mechanism: one for the hours and the other for the minutes, everyone made by an elaborated connection between weights, gears and ropes. Per saperne di più
