Here is a barebones one I made form that tutorial (was a while back)
I basically just took the the same thing from the breadboard.. (which I have made a couple laying around on the small breadboards from radioshack for quick dev).. and etched a home made/home brew PCB.. and used the same components.
(I then found a nice kit on line for $10.00..but doesnt have a vRegultor on it.. I put one on mine)
compared to the home brew on I made.. to the kit on-line:
Also.. you dont need a USB to Serial stuff..
just a quick (minimum of) 4 pin header.. for the FTDI uploading of sketches.
I use a $1.00 cell phone data cable I hacked.. it has the correct chip in it.. but I could NOT find a rest or dtr pin..
so I have to use the reset button on the board each time (not a problem for me)..
(I made a post here on it a while back)
