NeoPixel Planning

I suggest using a low-density NeoPixel strip. These contain 30 pixels, per meter of length. A 2-meter long reel of NeoPixel strips will work best for providing the sphere with total coverage of glowy. Take the whole strip and cut it on half so that you have two 30 pixel strips.



Solder Cable to NeoPixel Strips

These strips will need cables soldered to them. One of the strips will need both ends wired (The data in and data out connections). I used JST PH 3-Pin connectors with 28-AWG silicon covered stranded wire to create a 20in (50cm) long cable. This lengthy cable is connected to the strip that will act as the very first neopixel in the chain. A second cable, 2in (5cm) long is connected to the end of the strip with the data out connection. This second cable features a male JST PH 3-pin connector. 



Top Halve NeoPixel Strip

The second neopixel strip only needs one end wired (data in). I used a female JST PH 3-pin connector, with a wire length of 5cm. This cable plugs into the data out connections on the first neopixel strip.

3-Pin JST PH

It's important to match the colors of wires with connections. Follow this order: red colored wire connects to voltage (5+), black wire to ground (GND) and white wire to data (DIN / DOUT).
