Internet of things (IoT) sensors could connect via ambient radio waves

Internet of things (IoT) systems usually link networks of sensors via radio, but radios demand battery power thus limiting usability. Disney Research has determined that one solution may be to get rid of the radios all together and communicate via the ambient radio waves from TV, radio and cell phones. The Disney Researchers devised an … Continue reading “Internet of things (IoT) sensors could connect via ambient radio waves”

NVBOTS is making 3-D printing as simple as printing on paper

If you haven’t used a 3-D printer yet, you may be surprised to learn that it isn’t fully automated the way your office’s inkjet is.

3D-printing Bricks using Moondust and Sun’s Heat.

Bricks have been 3D printed out of simulated moondust using concentrated sunlight. This ESA project took place at the DLR German Aerospace Center facility, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000°C. A 20 x 10 x 3 cm brick for … Continue reading “3D-printing Bricks using Moondust and Sun’s Heat.”
