I didn't explain you right...
I need to connect a cable to upload the sketch to my atmega and thats it...
I will never connect it again...But i want to make a circuit or something so that I don't have to remove my original atmega from my arduino each time i want to upload to a new project board.
Is this possible? Maybe with some kind of connection on my duemilanove board?So that the internal atmega not work at all and just use the atmega on the strip-board. But is it possible without removing the first one?
