    I have posted Arduino source code for 3 projects which allows an Arduino Mega with an Ethernet shield to run as a DMX controller. Nothing new there except these support 8 channels of output ... not easy to do on an Arduino.


    WS2811 supporting up to 8 outputs + 8 Relays for dumb light string control:
    https://bitbucket.org/keithsw1111/arduinodmxws2811/overview
    Parts:
    Arduino Mega ~$9
    Arduino Ethernet Shield ~$6
    8 Channel 5V Relay Module ~$6


    40 relays for dumb light string control:
    https://bitbucket.org/keithsw1111/arduinodmxrelays
    Parts:
    Arduino Mega ~$9
    Arduino Ethernet Shield ~$6
    1-5 : 8 Channel 5V Relay Module ~$6ea


    GE Color Effects supporting up to 8 outputs:
    https://bitbucket.org/keithsw1111/arduinodmxgecoloreffects
    Parts:
    Arduino Mega ~$9
    Arduino Ethernet Shield ~$6

    These are all bench tested and working. They have not been speed optimised yet so no warranties can be made about overall performance.

    The problem is the W5100 shields struggle to receive more than about 3 universes. I am sourcing some W5200 shields which have more memory and 20x speed SPI to see if that helps me handle 8 UDP packets every 50-100ms. These are a bit more expensive $12.80 each. Still not bad ~$20 for a E1.31 controller.
