alt Hacker NewsAll those inductors... Isn't there a cheaper way to drive those lights, e.g. using DC voltage+pwm?

Yes each LED channel has an inductor. I needed this because I wanted the LED to be constant current driven, to reduce flicker and improve their longevity
(and they cost like 5ct each)
Those inductors are cheaper than what PCBWay charged for making that wooden box, I don't think their cost matters much here.
