Hello,

I am doing some research for a large LED system which can decorate my home and garden. definately I can buy the LED strips/chains from local Chandni market in Kolkata, but I just like to have a system where I can control the effects. And I have come to know about DMX 512 protocol.

my need is simple, to drive the LED chains through DMX and some control mechanism (software) through which I can design effects, test the channeles and get a preview how my system will work. I am a Linunx geek, hence I llike to do this with Linux box.

I have alredy found this circuit which can directly drive huge amounts of LEDs but not available locally

So I am in search of such a DMX board as well as it's power supply and the cabling guide. I understaand I need to do more reading on these as I am a novice in this field but a little guidane will definately show me the right track. Could anyone help me please ?
