That’s why you power them separately. 
that does sound intense @Ashley_M_Kirchner_No
I can push 100 pixels comfortably using an Attiny85 with the Adafruit Trinket core. I have a 2/3 lit up hoop in front of me doing a hue cycle.
NOTE: The tiny cores I posted earlier do not work. They are rather light and are missing some key instructions that FastLED relies on. Use the Trinket core instead (which means you’re also limited to only using the Attiny85.)
I actually forgot about this but, back in January I wrote a rather long piece about my setup and how I program a bare bones Attiny85: http://www.ka4designs.com/archives/372
that will help a lot thank you so is it better to use the adafruit or just the chip itself?
I used a bare chip, exactly as that post explains.
Oh perfect thank you
FYI, using the dithering branch of 2.1, I can push that up to 120 pixels … I can see a little white flag waving right above the Attiny on the breadboard …
Seriously though, you said less than 100 pixels, so you should be good to go using a tiny85.
