This is quick and dirty way how to get my "Matrix Pi" operating.

Matrix ip.jpg

The intent is not to provide lightweight Matrix like display but to configure my development environment. My UI is not ready yet but I want to test video output and stability under CPU load. Cmatrix is providing both, nice looking output and is using lot of CPU. In future I'll replace it with my UI ...

How to install

I am using raspbian-ua-netinst as it don't require interaction during install. Good thing is that installer-config.txt and post-install.txt are retained during re-install. I put my configuration script inside post-install.txt in way that installer is ignoring it but I can invoke it later after system is installed.

Step 1

Download installer and unpack it on SD card (for details check raspbian-ua-netinst).

Step 2

Unpack Matrix-pi.zip to SD card.

Note 1: installer-config.txt is only template.

Step 3

wait for installer to do it's job

Step 4

log to newly installed raspbian system and execute: 

bash -x /boot/post-install.txt install

Step 5

Enjoy matrix display on your monitor :o)
