The Lab Where Invisibility Cloaks Are Made #SciFiSunday

Warning Harry Potter fans, it’s not quite what you think. From The Atlantic:

Just before Christmas I finally got to see an invisibility cloak. I’ve written a whole book about invisibility—its myths, magic, and technology—but never before had I seen in the flesh one of the new devices that promise to make things vanish.

We all know what invisibility is, don’t we? Now you see it, now you don’t. Well, this invisibility cloak certainly wasn’t like that. It was housed in a Plexiglass box, and there was an on-off switch on the side. I was told to look through a viewing screen, through which I saw, in a gold-tinted mirror, the slightly distorted reflection of a toy panda. The reflection had a chunk missing where a couple of small triangular prisms, glued back to back and placed in front of the mirror, obscured the view. When the switch was flipped “on,” that missing part sprang back into view, as though the prisms had become wholly transparent.

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.
