We have finished our DIY Arduino on a solderless breadboard, and are about to move it to a perfboard for adding additional project components. We wanted to share this stage of the project to make it easier for others to do the same.
Components needed (Parts List):

Qty (1) FTDI / USB Adapter (just need the one for all additional projects, not one for each project)
** A quick note on the Arduino Revised USB FTDI **
Use RTS, not DTR for the auto reset, and opposite to convention, RX on the FTDI connects to RX on the Atmel, and TX to TX!
