Example of Completed - Standalone Project?

Hi,
I am looking for completed, round-trip example that shows the combination of code + a standalone ATmega328.
Although this example may not be 100% practical in real world, I think it would demonstrate how to:
a) create a simple sketch (The "Blink" example on the Learning page is a nice simple one)
b) transfer the sketch to ATmega328 chip for use on a standalone board (the result of the tutorial "From Arduino to a Microcontroller on a Breadboard")
c) Create a board that has ATmega328 as the center piece, and the circuit from the Blink example (this is the part I am having a hard time wrapping my mind around)
d) the use of an external power supply to run the finished example
I have searched the forum and cannot figure out how to combine the results of "From Arduino to a Microcontroller on a Breadboard" with "Blink" example to create a stand-alone, battery powered version of Blink - with ATmega328 -- not connected to the prototype board in any way. The finished product cannot have a USB or serial port.
A Fritzing breadboard layout of the above would really help understanding how to move from prototype to standalone.
Many thanks in advance.
Regards,
-Mike

Good Luck

For an interim step try the Perfboard Standalone

http://www.musheen.com/perfboard-standalone-arduino-ii-691.html

It offers step by step guide to translating the breadboard standalone to a soldered circuit.

It has the pin 13 blink circuit as part of its design.

You would only have to add a small voltage regulator circuit, the 7805 Voltage regulator and capacitors in the breadboard version, and a battery pack to pin 1 and 3 (ground and 5v) of the 6 pin programming interface to powere it away from usb.

Parts needed:

This version was designed to be plugged into a breadboard, but if you eliminated the attaching of the pins for insertion it will function as a standalone arduino blink.

Hope that helps.

A lot of my projects are stand alone. This one Chaotic Pendulum has schematics (down load them) for both arduino and stand alone. You can see the difference between them.
