Hi,

I'm new to this forum.
I'm writing here because I'm looking for a way to control light made with color led (rgb one or an assembly of a red, a green and a blue) with dmx signal. I'm a light designer (but not an electronician) and I want to built small rgb light (with a max of colors). I searched the web and find this site :
http://www.response-box.com/rgblights/
It was a solution to my project. I studied the project with the guy of response-box and we found a way to do what I want by hacking his product (by changing connections and cables that's all).
I bought him some of his product (for a value of 350$) and I'm still waiting for the products. Every time I tried to call him, there is nobody (one time I managed to talk with him on the phone but he hang off quickly pretending the connection was not good), he tried to make me believe that he's sending me the products and every time it's not true. It's now three months till I paid the products and I've received nothing.
It's now clear that I will never see my 350$ nor the products, but the think I don't understand is that this guy has a blog about his project, is an electronician who develop electronics solutions for people and he seems to be a croock.
Does his products are out of date (and he still want to make money with it without delivering them) ??
I really don't understand the logic of this kind of behavior.
Thanks for giving me some lights.

By the way do you know some products that could be some help in my project. I don't want to develop, I think there are many good electronicians on earth that have done that. I want to collaborate with somebody.
Thanks
