8 Ways Magnetic Levitation Could Shape the Future. For years, NASA has been researching the possibility of using the high speeds of maglev transportation to fling spacecraft into low Earth orbit.
"It would really open up space to human exploration and commercialization," Powell says. "It's something we can't do now because it's too expensive. " Powell and his colleagues have proposed two generations of space launching technology. Build a Touchless 3D Tracking Interface with Everyday Materials. Combine low-tech materials with some high-tech components and build a completely Touchless 3D Tracking Interface.
Explore capacitive sensing by using several panels of cardboard lined with aluminum foil. These panels, when charged, create electric fields that correspond to X, Y, and Z axes to create a 3D cube. With the aid of an Arduino microcontroller and some supplied code, movements inside the cube are tracked as your hand moves around inside the field. Amazing Trick.
