I loaded up the hardware docu for 2 Versions (sorry this took ages):
V1 is the one is the exact one of the logs (might miss some bits and pieces)
V2 is improved to make the build a bit es tedious mainly by using WS2812B already soldered on a lttle PCB breakout board, which also holds a capacitor 8current stabilization) and a resistor (over volatage protection). The V2 is not testet by me in the Türtris configuration, but the Breakouboard are used in sisams social gaming cube and apear to be less prone to damage while soldering and less prone for failure in use (in the door some LEDs miss one color).
If you note something missing in the docu, make a version with other measurements or have any other questions/ suggestions, feelfree to ask.
Note: V3 is planned to use lines of read soldered LED stripes, but will require quite some rework, because the grid has to fit the stripe pattern)
