Shown below is one of my DIY Arduino circuits.
The circuit does not have the FTDI chip built in. The FTDI circuit is only needed for programming and cutting out un-necessary components saves a bit of money. The ICSP connection (6 pins comming out the side) on this circuit is perfectly connected to the SparkFun FTDI breakout board:
or an FTDI cable:
Here is the Fritzing graphic:

Here is the parts list:
|1||5mm Red LED|
|1||0.1 uf Capacitor|
|1||Base 28 Dip .3 inch|
|1||1/2 Watt 10K Ohm Resistor|
|1||1/2 Watt 220 Ohm Resistor|
|2||16 Pin Header Connector|
|1||6 Pin Connector 90 degrees|
If you’d like to experiment on a breadboard before building (soldering) the circuit, here is the breadboard view:
