Help with my simple DIY arduino board so I can put my store bought one away for safe keeping.

Hi everyone,

I thought it would be cool to make a home made arduino compatible based on the atmega328 so i wouldn't have to worry about " frying" or messing up my store bought arduino when experimenting with something i'm not 100 percent comfortable with.  I've had some problems getting one to work, and i'm not sure if it is my design or maybe just a few bad components, or my lousy soldering skills.  anyhow, i'd appreciat it if someone could take a look at the attached circuit and let me know if you think it should work, or what I need to change.  thanks in advance.

I used fritzing to create the drawing.

    How are you trying to talk to the chip?

    i've got a rs232 to usb dongle works great on a breadboard.  I bought it on ebay.  plugging it into the 5v/rxd/txd/ground (i left the 3v pin off of my header in my design.  want to plug it into the female header on the board, you can see where i have run the leads on the board from the chip to the header.  i have attached a pic of it here.
