Fid shared a Neopixel hatband project in the Adafruit Forums. This hat worked great for Fid this year — 7+ hours of battery life!
I soldered 7 NeoPixels together on a 2″ wide ribbon along with a Gemma. The little battery hides behind the hatband just fine. I wore the hat at a party for about seven hours and there was still battery life when I took it off. I did set the brightness to 15 and it was bright enough.

Flora RGB Smart Neo Pixel version 2 – Sheet of 20: What’s a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable – so you only need 1 pin/wire to control as many LEDs as you like. They’re easy to sew, and the chainable design means no crossed threads.
So, you want lots and lots of NeoPixels? And you want them for less? Not a problem! Here’s a sheet of Flora NeoPixels fresh from the (reflow) oven. Snap them off as you need ‘em and save a pretty penny while you’re at it. Each order comes with 20 pixels on a snap-apart sheet. If you want a smaller number, we also have them in packs of 4.
