I’d just ebay it from a US seller. Do the strips vary much in quality? I would like to find the APA102 non-c variety, as supposedly they are in a better case with better heat dissipation. The APA102C are in really soft plastic.

I’m going to try working with the ADC input impedance and use just a single external resistor to ground. Maybe I can drag down the voltage from the LED just a bit to keep it under 2.56V. I’d like to try getting this down to: 2 LEDs, 1 resistor, 1 cap, 1 ATTINY, 1 button, and a battery holder.
