Follow the Bouncing Balls

 

 

Here's a quick video of an animated display. Simple but effective.

You may notice some brightness variations between the panels. This is due to the rough power distribution system I have used.

The LEDs have an operating range between 3.3V and 5V and from my experiments a variation of voltage directly affects the LED brightness.

This is disappointing because I was hoping that the WS2812B LEDs had consistent brightness control for its operating range.

The last thing I want to do is add components to the design to cater for this deficiency.

 

I had no such problems with 6 active panels, 9 and more are proving to be more of a challenge.
