Converting RGB controller to ESP8266 WLED Ws2812 Controller.

I am converting an old RGB controller to an ESP8266 WLED WS2812 Controller.  I removed the power transistors and cut the runs for the pull up resistors (Just to the left of the large pads where the power transistors were).  I tapped into the 5V buss at the top and the ground was available on a pin on the power transistors as marked in the picture.  D1 D2 D3 go to the large solder pads where the power transistors were mountd. I should have used resistors for the D1-D3 lines.

Here is the completed modification.  I see I need to redo the soldering conection and use some smaller heatshrink.  It needs to be relabeled as well.

These are some of my LED panels.  In the back is a 72x32 array then a 72x16 then a 72x16 and then a slightly smaller 68x16 array. In the front is a 64x32 display unng 16x16 LED arrays.  I have two more of the 72x16 arrays that are not in the picture.
