LED Network Status Board

PROLOGUE

Red pixels: TCP ports
Green pixels: UDP ports
Blue pixels: other hosts in /18's

Brighter the LED, the higher the port/host per assigned pixel.

This project came out of the desire to have more blinking LED’s in my life. You can simply purchase some Neopixel boards, connect them up, toss them on a Pi, and feed that code some info from a sniffer.

Core Components Needed

1. RaspberryPi 3 with Raspbian
   
2. Source Code
   
3. Four LED Grids
   
4. One Power Supply
   
   
   Let’s get it on
   

1. Connect/Solder up the panel’s INPUTS/OUTPUTs, and extend the voltage injection. It’s pretty darn simple.
   
2. Install Raspbian
   
3. Install rpi_ws281x on the RaspberryPi : https://github.com/jgarff/rpi_ws281x
   
4. Install any missing Python libs via pip
   
5. On the sniffer box, use CPAN to install all the required libs
   
6. Change the hostnames/IP, subnet filter range, and ethernet interface to sniff
   

Start the scripts

sudo python server.py
./sniffer.pl
