So I originally wanted to go heavy on some RGB LEDs on the timer instead of some kind of LCD display (character or graphical). I wanted it to be functional, but have some kind of colorful fun factor. I was worried about the power requirements of a bunch of LEDs, and for good reason.
I've been looking into using some 8mm diffuse NeoPixels from Adafruit, but the power rating on them maxes out at 60mA at full brightness. The 15 I wanted to use adds up to 900mA if all are on a full brightness. That's almost twice what I can draw from the LiPo Boost converter I'm using!
Now, I'm probably not going to run all of the LEDs at full brightness at the same time, but I'm probably closer than I'd like to be.
So I have to do something. But I have two options: reduce power drain, or increase power supply. Decisions, decisions.
