Koontz - The Sundial: Koontz - The Sundial
R99 Discovery Miles 990 Shipped within 6 - 7 working days

Can you tell what time it is without a watch or a cell phone? Sure you can! Sundials have been telling time for thousands of years. Now you can build a watch-style sundial with this kit from Koontz. Using the same principles as obelisks and shadow clocks, sundials can be aligned to be parallel to the Earth's axis of rotation and use your own geographical latitude and the sun's position to tell time. A gnomon in the center of the sundial creates a shadow that lines up with the current time. So shadows are good for something besides spooking you in the middle of the night and shading you during hide and seek! These shadows actually show you what the solar time is! The sundial watch is assembled from 23 cardboard pieces with a working compass on the watch face. Use the compass and follow the instructions to orient yourself so you always know what time it is. No batteries necessary!

Italeri Model Kit - Leonardo Da Vinci Catapult: Italeri Model Kit - Leonardo Da Vinci Catapult
R334 R285 Discovery Miles 2 850 Save R49 (15%) Shipped within 3 - 5 working days

The catapult was a medieval weapon which Leonardo reworked and improved upon. As shown in the drawings on page 140a/br of the Atlantic Code, which represent six designs of a spoon-shaped catapult, the loading mechanism is activated by two large flexible wooden arms that increase launching power. The stone or metal projectile is placed in the spoon-shaped end of a long lever. The loading operation turns the large central pin and flexes the curved wooden arm. The safety catch is then released to launch the projectile straight at the target. The launching power is proportional to the length of the lever arm and so the energy involved in throwing the projectile is high, allowing the projectile to cover particularly long distances.

Italeri Model Kit - Leonardo Da Vinci Mechanical Lion: Italeri Model Kit - Leonardo Da Vinci Mechanical Lion
R411 R352 Discovery Miles 3 520 Save R59 (14%) Shipped within 3 - 5 working days

Sheets 90/v and 91/r of the Madrid Code include drawings of strange mechanisms that are not linked to the treatise on mechanics and often have no explanatory text. Analysing them led to the reconstruction of mechanisms enabling a mysterious animal, a mechanical lion, to move robotically. The lion, a gift from Pope Leone X and the town of Florence, was taken to Lyon, in France; on July 12 1515, at the end of a surprising, magical walk before the King of France, Francis I, it stopped knocking some lilies over. It can be considered one of the first animal-like robots ever built.

Italeri Model Kit - Leonardo Da Vinci Paddle Boat: Italeri Model Kit - Leonardo Da Vinci Paddle Boat
R411 R352 Discovery Miles 3 520 Save R59 (14%) Shipped within 3 - 5 working days

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
