POV display possibility with ws2812b neopixel strip
No the WS2812 will not work well for Persistence of Vision applications.



My toy POV has over 100 updates per revolution. You can change my assumptions to see what other designs might be possible.

Also note that the WS2812 uses PWM to control the brightness. I don't know if the PWM frequency is fast enough to be unnoticeable. Although, you could run at full brightness.
