Rohinni has created a way to print lighting and apply it to any surface. via FastCoLabs:
In its current state, Lightpaper is manufactured by mixing ink and tiny LEDs together and printing them out on a conductive layer. That object is then sandwiched between two other layers and sealed. The tiny diodes are about the size of a red blood cell, and randomly dispersed on the material. When current runs through the diodes, they light up.
The promise of thin lighting has been simmering for a while, thanks largely to breakthroughs in OLED technology. But nothing viable has come to market, and Lightpaper is much thinner than OLED—which has been able to get TVs down to a fraction of an inch thick—and is lower cost and has a life-span of around 20 years, like LEDs.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
