Nice build! What are you driving it with? In the third picture it looks like it’s wired to a light bulb box… :slight_smile:

Lol, the box is just a mounting spacer. I drove it with an Uno and powered it by a 2A USB power supply.

Nice layout. Bonus points for using a folding ruler.

i bought a sheet (10x10 tiny pcbs) of WS2812s, and i was waiting for a use for them - great idea, great effect with just 25 LEDs!
