Neopixel Track
This is a track made to fit the Adafruit Neopixel LED flexible strips. I've used the 60 pixels / meter strip for the design but it should work for the other Neopixel strips as well.
This design is meant to have the pixels facing away from the viewer and placed on some sort of mounting board that will reflect the light back through the plastic providing an interesting diffuse glowing affect without the normal glare associated with these very bright LED strips. Along with the tracks, I've included end-caps that can be used to hide where the wires will connect to the Neopixel strip, a coupler to join two tracks together for longer runs, a corner joint and a three-way joint. These add some architectural interest to the tracks.
