Printed Circuit Board Design

The circuitry prototyped thus far has been on a breadboard. For the final implementation something less fragile would be better.
I contemplated using the soldering type proto/experimenters board, but ultimately figured it would be cleaner and more fun to attempt to make a PCB.

After a little research into PCB design programs, I found fritzing.org. I like that the project is open source and that it ties in with arduino.

Fritzing is an open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics.

I found the program simple to use and reasonably stable (though I advise saving frequently). You can design the PCB by starting in a "breadboard view". You build up a circuit by simply dragging required components into the workspace and adding connecting wires. Then selecting by "PCB view" you find the skeleton of your PCB and you are left to decide where to lay the paths. There is also a "Schematic view" if you wish to make a circuit diagram.

After a bit of work, I produced the following PCB layout.
