That’s 1000 WS2811, IP68 LED’s with about 9cm spacing in strings of 50.
Or, roughly enough to cover a 4 meter by 1.5 meter area.
I’ll need maybe 6 of them to cover the house frontage
50mA per LED…6000 LED’s…that’s gonna be 300 Amps at 5V. Sounds a lot but that’s maybe 3KW , fine from a domestic plug here in Blighty.
The plan. A house sized, low resolution TV
