My device now works on the breadboard, with wires running to the Arduino. Now I want to wire the circuit up and install it. It's not a complicated circuit, so I plan to use perforated circuit board and soldering wires rather than making a printed circuit board.
What do I need to replace the Arduino in the circuit besides just the ATMega chip? I'm using the SPI pins and some of the digital and analog pins. But nothing like the USB port or the like.

They also sell cheap 3-axis accelerometers.
Good point. I saw those accelerometers. Plus the gyroscopes. Besides the RBBB Arduino, I need a set of accelerometers plus gyroscopes. Glad I was pointed to that site.
To ask another rather stupid question, what gauge wire is best for wiring this all up?
Soldering is a pain in the butt. I prefer wirewrapping it all together. I solder some sockets (just the corners) in place on a single sided perfboard, then wirewrap from there.
And I gave up on sockets even - i just use wirewrap socket strips like these since you can't get a socket wide enough to plug a promini into.
30 guage works wonderfully.
Heavier stuff is good for off board connections, where some wiggling could occur as you assemble/disassemble during build/debug/repairs, etc. But laying down wire that will not be moving especially when several chips are involved, I find wirewrap the way to go.
