I have been experimenting with the AdaFruit Neo Ring as I want to use it on my InMoov Robot. Based on all the documentation it is recommended to add a capacitor and a couple resistors to prevent burnout from a sudden surge.
Below is a direct quote within the Sketch that AdaFruit provides for testing.
// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across // pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // and minimize distance between Arduino and first pixel. Avoid connecting // on a live circuit...if you must, connect GND first.
Here is a picture of the breadboard I created to test with.
Here is a video showing the Neo Ring running the AdaFruit test code.
Now that I was able to test and verify the circuit, I wanted to have a professional board created and branded. After some time designing the layout here is what I came up with.
I will likely offer these for sale if someone is interested in them. I will likely be able to offer it as a loose kit or fully assembled kit. I have to get them first so that I can see the quality and test them.
NOTE: I am not the creator of this robot. The InMoov Robot was created by Gael Langevin, you can read more about it here: http://inmoov.fr/.
