Neopixel hatband

by Fid on Wed Oct 30, 2013 10:08 pm

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.
One of the NeoPixels is acting strangely. It is the one on the left-hand side that is flashing white at full brightness. I don't know the cause. It doesn't do it all the time.

Sounds cool! Any photos?
It is the one on the left-hand side

Where is that in the strand of pixels? First? Last? Somewhere in the middle?

Photos disn't come through. Use the "upload attachment" tab under the message edit box. There is a 1meg limit. Re-size to 800x600 usually works well.

That's interesting. The preview shows the pictures inline. The post only has image names.
The LED that is flashing is the last one on the string, furthest from the Gemma.

I'll have to upload again in a little while. The two pictures are 682.5k and 226k. Just a touch over.:D

I may have a short or cold solder joint causing the LED to freak out.
