Another interesting form factor for the WS2182B NeoPixel LED — named by Adafruit as the the NeoPixel Jewel, a twee but not inaccurate name for these lovely little pieces. Even without electrons rushing through them, they are fine and attractive objects.
These basic elements can be used as new primitives with which to create larger geometric structures. Other primitives will offer further possibilities.
Two of the 3-Jewel primitives, used for creating larger geometric structures. Running a test routine. Note particularly the difference between the cool white LEDs (~3000K) and the warm white (~7000K).
Three more Jewels soldered, yet to be connected with three Corner Cubes — this is hard work.
