TETRIS TIME CLOCK ON A P10 RGB MATRIX WITH ESP8266

Last month I built a new version with a 32x32 matrix that fits perfectly in a IKEA ribba frame.

This time I used Brians Loughs D1 matrix board to optimize the cabling. Have a look at his boards if you like to build something similar: https://www.tindie.com/products/brianlough/d1-mini-matrix-shield/ 

I updated the code to make it work with the recent versions of the libraries.

This one is powered by a old 12V power supply and a LM2596 buck converter.

In the first version I wasn't very happy with the clearness of the pixels. The matrix isn't flat, because the front plate has thin horizontal ridges the lat the light flow to neighbor pixels.

Dominic Buchstaller gave me a hint:
You can loosen all the screws of the panels so that the front plate can be taken away. 

Then you have two options:

1. Leave the front plate and just rescrew the matrix. Then the LEDs fit nicely into the printed grid.
   The drawback is that you can't use a diffusor between matrix and printed grid.
2. Turn the front plate around so that a flat surface is created and then resrcew it.
   I chose this option and it looks much better.

Loosen the tiny screws:

Take away the front plate:

Turn and rescrew it:
