This tutorial will go through the steps involved in fabricating your own Arduino-compatible circuit using just ~$8 of parts (this includes the ATMega chip!). This is perfect for installing and embedding in permanent pieces , as you don’t need to waste a full $30 Arduino board in a project you will never need to reprogram or touch ever again. It is also great because you can solder any custom circuits (LEDs, other ICs, any external analog circuit) on the same board, and customize in terms of shape and size.
He purposfully makes all the connections on the top side of the board to make it easier to learn how to wire this circuit up yourself! The photos are great, the language is accessible, making this a tutorial you’ll go back to over and over for lots of projects!

This is very similar to the circuit board for the $50 robot at http ://www.societyofrobots .com/step_by_step_robot.shtml which is a tutorial for building a $50 robot aimed at relative beginners.
More details on just the build of the printed circuit board are shown at http ://circuitgizmos .com/wordpress/?p=471 with step-by-step with tips and pictures for making the assembly easier. Three parts to this blog.
The $50 robot PCB is aimed at adding headers for servo motors, but the basic layout and construction still apply.
I think this post shows a true aspect of how to make a true embedded system, I mean, just like the post says, if your are going to actually use a board for permanent use, there is no reason why you should spend ~$30 compared to ~$8. I usually buy boards when I know I can get many experiments or temporary projects out of it, but for the permanent jobs, I do prefer custom and cheap.
So I give a big thumbs up on this post!
Cool. Arduino has many advantages over regular AVR’s. Though burning a bootloader is a concern!
