I have been playing around with my arduino I have never really spent a lot of time getting my Ethernet shield working, Today I set out to try and get it so I could read the sd card from a browser without a whole lot of trouble, all went very quick, Now I am going to move forward now that I have the Arduino communicating . what I am thinking about is doing something with home automation as far as my HVAC equipment, I am not sure how intense its going to get or if its even worth my time.
I have also been looking at the Raspberry PI as my next platform to build on. I have wanted to get one for a while now and finally getting around to it.
