[quote]The class I build on the pc side can be used also on the Cobra.

That is one of the great things about .NET, if you use the MF subset on the full .NET your code will work on the Cobra with almost no effort.
I have also developed code for the W5100 beta ethernet support, and moved it to the Cobra, and a PC.
Eric i have a question. As you remember i told you in my project topic that i will use Z-wave to control the lights,electiricity. What is the idea in your project?
I see on your image (1st post) that you will use Kaku with RF433. Is this better and easier way? Can you give me some more details because i don’t know much about it? thanks 
I’m not versed in C# enough to really help but I will do what I can. This is similar to what I am trying to do now with my Hydro project. Also I am planning on taking a C# class this fall to help me with my projects and maybe I might be able to help you as well. Tell me how I can help and I will be glad to do what I can.
