I've been thinking. If you want a lot of different projects all at the same time, you're going to need a lot of arduinos. So, rather than buying up a bunch of duemilanoves, it may be better to just buy a bunch of atmega 328 chips, program them with one board, and just swap them out into a breadboard when I need them.
That raises the problem of components for the breadboard version of arduino. I like compactness and I'd rather not have a bunch of components on the board if I could combine them. I've seen people that have soldered all of the necessary components directly to a chip, which I love the idea of. However, will there be any problems when I insert the chip into the main arduino board?
To clarify, I want to know if there's anything wrong with putting something along the lines of this:http://www.geocities.jp/arduino_diecimila/obaka/project-2/index_en.html
into the arduino board where the normal chip goes, just to program it and then remove the chip for the project.
