Hi *|FLNAME|*,

Exploiting the human eye’s persistence of vision, the myGlobe project uses a single strip of 25 LEDs to produce a glowing orb of light to display images.

Designed by Viktor Pankov, an Electrical and Electronic Engineering student at the University of Manchester as part of his industry placement at National Instruments, the device spins at 1,200 revolutions per minute, whilst simultaneously blinking the individual LEDs at 2,200 Hz.

The human brain registers discrete sequences that happen faster than 20 Hz as a single continuous image. This enables the myGlobe to display a world map, for example, to the human observer despite consisting of only a single LED strip.

You can find out more about Viktor Pankov the project here.

Toio Interactive Robot Cubes with Optical Pattern Localization

Designed by Sony, each Toio robot cube has a small lithium-ion battery that lets it drive for about two hours. The Toio kits come with special mats that enable optical pattern localization: This method allows robots to find their position by using a downward facing camera and looking at patterns underneath them. The robots then communicate with a centralized controller to simulate interactive behavior with one another.

Meet The 89-Year-Old Aiming to Disrupt the RailRoad

89-year-old Max Schlienger is an accomplished engineer who leads his family-run company, Flight Rail Corp. Its sole product, the Vectorr system, uses a propulsion method that utilizes what Schlienger describes as a “thrust carriage”. The thrust carriage is connected to the train with powerful magnets and moves back and forth through a pipe under vacuum power, bringing the train with it.

These Drones Use WiFi to See Through Walls

For this experiment Researchers at the University of California, Santa Barbara used two drones. One sent Wi-Fi signals from one side of the structure, while the other picked up what was left of the signal (the received signal strength or RSSI) on the other side of the walls. The result is a pretty decent image of what’s inside the building.
