Moving up from proto boards

[chandin]

So I was wondering say you have your idea working fine on an arduino or mbed or whatever. What are the next steps to make a self contained board for your project. I looked in google but did not find anything promising.
Is there an episode about this?, If not it would be a good idea.
But till then please enlighten me on this thread

You pretty much just duplicate the parts of the arduino board circuit diagram, that your project uses, onto your own pcb design.
Adding in any external components you attached to the arduino.
