Hey everyone, I have loved the community and products you have available, but the "hacker" in me wants to build one on a breadboard, just to see it feaseable 
I have found this awesome "hackduino" tutorial that builds a small Arduino board, and I thought this was awesome, and I have been playing around with it along with my Uno while working on one of my projects, but the next thing I would like to try is maybe building a breadboarded (or perfboard) Ethernet interface.
Do you guys have any ideas? I'm relatively new to this community, however I understand most of the ideas (AP Physics was a good start, but I have been doing some reading on the side and experamenting) but I need a lot of guidence.
What I would like to do, is have my breadboard uno-like board, and build an ethernet module so I can connect this strait to my router (and configure the port forwarding) so I can send a command strait from any other computer to this module, then turn on a simple LED.
Any help would be appreciated!
