Lens-free OLEDs with efficiency comparable to that of inorganic LEDs The use of organic light-emitting diodes (OLEDs) has extended to various applications, but their efficiency is still lagging behind inorganic light-emitting diodes. In this research, a KAIST team provided a systematic way to yield OLEDs with an external quantum efficiency (EQE) greater than 50 percent with an external scatteri...

Made a spiral #Christmas tree out of a 5-meter strip of APA-102 #LEDs .  I think it turned out pretty good for being made out of some leftover #PVC and steel wire.  It's being controlled via a ~$2.50 #Arduino Pro Mini clone with a 2A 5V wall wart sitting inside a cheap Ziplock plastic container. It's running a slightly modified version of the ColorPalette example in the #FastLED library.  I...
