I'd like to convert some of my PC case fans to be compatible with Corsair's RGB system to fit with other case fans.
Corsair has an RGB fan hub that allows you to connect RGB fans to it, then connect that hub to an RGB controller. I plan on using this to connect all my LEDs.
For the RGB controller I plan on using an Arduino Uno, because I like the idea of being able to program my own pattern. So the Arduino Uno would take the place of the RGB controller switch that gets connected to the LED hub.
Corsair's RGB fans are just WS2812B LED strips. However their strips have a data in and out connection.
So after one fan or strip does its function, the next fan or strip in the series does it's function, and so on.
So i'm curious how i'd use stock WS2812b's in this system. I already know which molex connector the hub uses, but I'll need to somehow populate the "data out" wire going to the hub.
A teardown of the Corsair fans themselves show the D/Out is right next to the D/In, so i'm wondering if these are proprietary strips or if they're just tapping into the D/In.
So essentially I'm going to wrap an existing case fan with a strip of WS2812b's, and connect them to the RGB hub with a molex connector, but I need to know how I'd turn the standard 3 wire WS2812b into a 4 wire connection that includes a data out wire.
