New guide in the Adafruit Learning System: Sipping Power With NeoPixels
Planning to incorporate NeoPixels into portable, wearable or cosplay projects? The way NeoPixel power needs are usually estimated, you might think you’ll have to carry around a car battery or a Mr. Fusion reactor. With some foresight, it’s possible to put on an impressive display — and run it for hours — from modest power sources.
The key to making this work is to approach the problem from the other direction: not how-much-battery, but how-little-NeoPixel can you get away with? Thoughtful design in layout, color selection and animation patterns make an enormous difference in power requirements.
