Making Clock as Working Hours

Clock - one of the most popular characters in culture. They symbolize the time, his transience, or, on the contrary, eternity. Clock - is an attempt to man, impotent in front of the passage of time, at least keep track of his progress. For many hundreds of years of its existence, the clock has undergone many changes.

Time - is a phenomenon that a person is not able to accept any of the senses, therefore, feel the time he helped the changes occurring in the nature. The earth revolves around the sun, so the amount of light that informs, day or night. That Sun and became the first person in the benchmark time. Sundial - the most ancient of all invented by man. They were a common pole stuck in the ground, and was drawn around the timeline. The shadow that falls on the earth from pole served as an arrow. These watches are now often the decoration of parks, and to make them possible and at home by using a piece of paper and a needle. And you can get the rotating LED clock to make one for yourself.

Later appeared sand or water clock - they measured out the time in which sand or water have time to fully move through a narrow opening at the top the bottom of the clock. The first mechanical clock appears to be considered Antikythera mechanism. That is, he certainly was not the first, but it is the oldest preserved example. The mechanism was found in 1901 in the wreck near the Greek island of Antikythera. It was a 37 bronze gear in a wooden case, equipped with dials and was intended, apparently, to calculate the motion of heavenly bodies. 

The first mechanical clocks set in motion by means of lowering the load. Stone or metal cargo tied to twine or rope wound around a rotating shaft sinking, this resulted in the movement of the shaft. These clocks were used, for example, in urban areas. Later, Galileo perfected the pendulum Herbert, who later came to be used in watches. In such hours were used vibrational laws. BTW, you can select the rotating LED clock at Banggood. Besides, you can easily get other electrical accessories (e.g. voltmeter car) there with high quality and reasonable prices.
