RGB LED Christmas star

thingiverse

RGB LED star with 6 individually controllable LEDs per star. (a star is approx. 18 cm in diameter and 16 mm thick) https://www.youtube.com/watch?v=4j7HtS_lw7M UPDATE may 4th 2015: Yesterday I connected the first 10 of these stars together, here is a small video update. (just running the default example-code, included in the adafruit neopixel library)https://www.youtube.com/watch?v=-Yzz428QVe8 Instructions I'm already working on my Christmas lighting project for this year. I still need to print about 500 of these RGB LED stars, besides a few thousand smaller ones! I use "transparent" filament (PLA), for optimized LED performance. This RGB LED star can be fitted with a piece of LED strip. (I use 5050 RGB addressable LED strip, 30 LEDs per meter, WS2812 controlled) So, each "tip" of the star, can be set to another color, and the middle of the star also does have its own LED in one of the star tips, there are two small holes, so you can put a wire through it, to put the stars up. Beneath the "middle" part with the middle LED, there is a hole, to fit the 2 four-wire cables. (one cable from main controller or previous star, and one cable to the next star) Stars are approx. 18 cm in diameter, so they fit nicely on a 20 cm printbed. Stars are 16 mm in thickness. (2 mm bottom, 12 mm for the LED strip, and 2 mm for the top) cut five LEDs in one piece from a LED strip. cut one LED from a LED strip. put the 4-wire cable (coming from the controller or previous star) through the bottom-hole, and solder it to "in" side of the LED strip with 5 LEDs. (make sure the colors of your cable fit) Solder a small piece of wire to the "out" side of this 5LEDs piece of strip, and solder the other side to the "in" of the 1LED strip. Put the second 4-wire through the hole, and solder it to the "out" side of the 1LED strip. (This wire will go to the next star) glue the 1LED on the "middle part". glue the middle part over the hole with the two cables. put the 5LED strip piece around the 5-corner shape, and put a bit of glue between the LEDstrip and printed shape. Eeh voila! Connect to Arduino or other MCU of your choice, and let the colors run.
