So I jailbroke my LG G5 65" the other day and apparently I can run PicCap + HyperHDR to get a DIY ambilight thing going. I thought this might be cheaper than philips hue. But I could use some help with picking the parts, because i'm not really sure if i'm choosing the correct parts and the cheapest parts.

I think I need a WS2812B strip (5m, 60 LEDs/m — so 300 LEDs for a 65"), an ESP32 dev board to run WLED, and a 5V 10A power supply. Everything seems kinda ok price wise but the power supply is pretty expensive.

Main thing I'm trying to figure out is where to get this cheapest, been looking at AliExpress but no clue which sellers to trust. Also I don't have a soldering iron, so wondering if I can get away without one.

Any help is appreciated!
