Hi there
I'm still learning my way around, l'm in the process of building the Kaleidoscope Neopixel goggles with bluetooth control. heres the link to the project page: https://learn.adafruit.com/kaleidoscope ... nket-gemma
However the details of the project only mention a 150mAh or a 500mAh battery.
For these goggles l'm building, l want them to last longer so can l add a 2000Ah battery instead? If so, then do l need to make any changes to the wiring or the neopixel coding?
Also how do l change the neopixels from the rotating lights function to just a still light function that doesn't move around? l appreciate any help you can offer. Thank you

A larger LiPo batter would not require any changes to the wiring or the code.

Re: Use larger battery on Kaleidoscope goggles project
for what its worth, This past weekend I wore a set of these googles to an event with the stock adafruit rainbow/ecto sketch with brightness = 85. At this brightness level a new 500mAh battery ran the display all night, ie at least 8 hours, and no less than 12 when I bench tested it. After dark you could probably lower the brightness some more, for extra run time.
I've not worked a run time out for the goggles including the bluetooth LE module yet but plan to figure it out in the next few days. I need to complete the modular set-up I have in mind in case I don't want bluetooth control for some reason (power restrictions, interference,...).
My guess is that run time is highly dependent on how much the bluetooth control is used?

Re: Use larger battery on Kaleidoscope goggles project
Bluetooth LE is fairly low-power. But it will still have an impact on battery life. Transmit takes more power than receive, so if the goggles are only receiving it should not be too bad.
