These magical "brain holes" from the LED come to watch [Full text]

In this world of science and technology , there are always some unexpected inventions that will surprise you with the "brain hole" of human beings. Today, we will talk about some of the magical ideas related to LED technology.

World's first LED glare interactive runway launched

Recently, Nike built the world’s first LED runway in the Philippines’ capital Manila, Unlimited Stadium. A cool runway, a shadow that can run against himself, allows the runner to run out of new tricks and make the sport more interesting. The shape of the track is like a 100x enlargement of the NIKE Lunar Epic shoe print. From a high altitude, the runway is like a “giant shoe print,” stepping in the center of the city. Nike's name for this fluorescent track is “unlimited,” which means that it constantly surpasses its limits during the run. The entire runway is equipped with LED display, magical lighting effects make the entire running process full of passion.

To run on this track, you must first wear an RFID RFID sensor on the sports shoes and set a good completion time. When you walk on the runway, a virtual character will appear on the LED screen to follow you. Its speed will be adjusted according to the expected running time you set and your actual running speed, sometimes fast and slow. When you complete a running plan, the sensor analyzes your completion time, running speed, and other data, and sends the analysis results to the system to adjust the running speed of the virtual character. If you can keep up with the running speed of the virtual character or catch up with it, the running plan is completed.

Malicious program steals through the router LED light

Researchers at Ben Gurion University in Israel have developed malicious programs that can control LED lights on devices when installed on routers or gateways, use LEDs to transmit data in binary format to nearby attackers, and attackers can use video recordings. Device to receive data.

Researchers had previously discovered that they could use stealth hard disk sounds and hard disk LED lights on target computers to steal data on non-networked devices. In the latest research, there are more LED lights on routers and gateways, so stealing efficiency can be higher. Researchers say they can steal data at a rate of 1,000 bits per LED. The researchers also announced a video (Youtube) demo attack.

Outside the multifunctional all-in-one lighting electronics tree

According to Hong Kong’s “Wen Wei Po” report on the French street species of electronic trees, France’s central city of Nevers recently “planted” the first e-tree in Europe, the shape of the future is full of its huge square solar “blade”, can convert sunlight into electricity, for Pedestrians charge their mobile phones, surf the internet, or use the cool air.

The e-tree was developed by Israel's Sol-logic and inspired by the Arabian gum trees on the Israeli desert and African grasslands. The e-tree not only provides drinking water, but also powers street lighting. It also offers free Wi-Fi, seating under a tree, USB charging, LED screens, a fountain, and a sink for pets.

A Pair of "Electric Eye Full" LED False Eyelashes

A false eyelash made of LED lights can make your eyes truly "electrical", with both eyes flooded. According to reports, this "flashy eyelashes" was first created by designer Tien Pham. Although it has its cool appearance, its wearing method does not require special installation techniques and can be glued with eyelashes like other false eyelashes. This LED false eyelash can display a variety of colors, such as pink, red, blue, light blue, white, yellow, green, and so on, so as to present completely different visual effects. Even the changing modes of light can be selected, such as scrolling, dance and strobe, and the user only needs to switch by pressing the button.

According to Tien Pham, its built-in 3.3-volt battery will last for about 4 hours, and it will be waterproof, with no obvious heat, and it will barely feel it. At the same time, he also said that there is no need to worry about the light of the eyelashes will flash to his eyes, because its light is very weak, you have to cover your eyes to see the light. In addition to this, this eyelashes is also equipped with an Arduino controller to control the light, the volume is very small, can be fixed on the hair with a hairpin. "I want to make the product lighter. The controller is fixed behind the user's head with a hairpin. There are thin lines that connect to each eyelash, but they are barely noticeable unless someone closes it."
