Here are a few tutorials on breadboarding an Arduino using an ATmega8:

Building an Arduino on a Breadboard

Minimal Arduino with ATmega8

Make a standalone Atmega8 circuit


You will need an AVR compatible programmer of some sort to initially program the bootloader.

Simple Serial Programmer for AVR

AVR In-Circuit Serial Programmer

Using an Arduino to Program an AVR

Also search the forum, there are numerous AVR programmer designs posted.

Thanx 4 helping ...
I used the circuitry in "AVR In-Circuit Serial Programmer" .
But i cant erase or program . I'm using direct serial port,,ponyprog2000..
Is there any troubleshooting options? I need some advice ..!
One more thing ,when i ignore programming ..it starts programming .. verifying..and ends with failure message.

I use both the Atmel JTAGICE or AVRisp for my AVR programming requires, therefore I have no experience with any of the DIY AVR programmers.

I would recommend searching the forum for threads in reference to the ponyprog or starting a new thread concerning this topic.

I'm quite sure there are numerous members who can assist you with those issues.

If you have one bootloaded ATMEGA IC then its very very easy to burn bootloder on another one without need of any programmer.
