Make a display using addressable LEDs, 10-12 m long, 8-10 strands wide. Using LEDs with a 10 cm pitch, make the strands 10 cm apart to give a long narrow matrix effect. Wire connection rather then flex PCB looks better. 12v is better than v; at 10 m there may be too much power drop off with 5v strips.
With a LED spacing of 10 cm, need 100 x 8 = 800 – 1200 LEDs, or in total strand length 80 m – 120 m.<\/p>\n\n\n\n
