This True 3D display technology, developed by Burton, uses a laser to creates luminous points of light at desired locations in air or underwater.
This system is an evolved version of technology co-developed by AIST and Keio University, first announced in 2006. It works by focusing laser light, to produce plasma excitation from the oxygen and nitrogen in the air. The researchers state that this is the world’s first technology to show pictures without the constraint of a screen.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
