Flexible LED lights strips operating on DC12V (11-13V) you can easily create decor lighting for any place. The high-quality LED strip has a double-sided adhesive tape at the back. LED center » How many LEDs can I drive in series? It depends on your supply voltage.
You have to be able to overcome the cumulative forward voltage of the series combination in order to get them lit. As an example, with a 12 VDC supply, you could drive up to five red LEDs (2.1V @ 20 mA) in series. The current isn’t used in the calculation: 5 * 2.1V = 10.5, which is less than 12, but 6 * 2.1V = 12.6 which is over 12, so five is the maximum series combination for that type of LED at that supply voltage. When you need more, you can build arrays by combining multiple series strings in parallel. In that case, your load current needs to be calculated and kept lower than the rated supply current.

The larger pentagons outlined in pale blue were constructed using a large-scale girih tile pattern, and the small white pentagons were constructed using a small-scale girih tile pattern.

In this unit we'll show that the plane figures, the polygons, triangles, squares, hexagons, and so forth, were related to the numbers (three and the triangle, for example), were thought of in a similar way, and in fact, carried even more emotional baggage than the numbers themselves, because they were visual. This takes us into the realm of Sacred Geometry.

Universal robotic gripper. Robert Barker/University Photography The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge.
Opting for simple elegance, researchers from Cornell, the University of Chicago and iRobot Corp. have created a versatile gripper using everyday ground coffee and a latex party balloon, bypassing traditional designs based on the human hand and fingers. They call it a universal gripper, as it conforms to the object it's grabbing, rather than being designed for particular objects, said Hod Lipson, Cornell associate professor of mechanical engineering and computer science. Is the Universe a Holographic Reality? The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm?
In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. Crystal Egg Geodes - Martha Stewart Easter. Us Now. A film project about the power of mass collaboration, government and the Internet. In his student flat in Colchester, Jack Howe is staring intently into his computer screen. He is picking the team for Ebbsfleet United's FA Trophy Semi-Final match against Aldershot. Around the world 35,000 other fans are doing the same thing, because together, they own and manage the football club. If distributed networks of people can run complex organisations such as football clubs, what else can they do? Us Now takes a look at how this type of participation could transform the way that countries are governed.
Us Now follows the fate of Ebbsfleet United, a football club owned and run by its fans; Zopa, a bank in which everyone is the manager; and Couch Surfing, a vast online network whose members share their homes with strangers.
