There are dozens of Arduino boards out there that cost around $20 to $65 based on the size and functionality of the board. But if you are a little short in your budget and can survive without the fancy look, you can come up with the one that costs less than $8. Just plug them into your breadboard and make the word’s cheapest palmtop computer(!).
I have posted a tutorial on how to make your own Arduino board with the minimum cost $8. Hopefully it will help others to make their own custom Arduino board.

Hey, great job. That's all very helpful. I've bought a bare bones Arduino but had never figured out how to make one on a breadboard. Now I can.

It's good to hear that. I will appreciate if you leave your feedback on the website.

You might want to mention in your tutorial that all the timing will be off (2x too slow), since you're using a 8 MHz crystal and a 16 MHz value of F_CPU.
-
@rbtying: It was a mistake, the ceramic resonator was 16MHz. I think it solves the timing issue. Doesn't it?
-
Yes, it does.

i hardly ever use the arduino board and usually opt to solder a carrier board that costs less then a $30 arduino board. in fact i can't even fathom why anyone would opt for the original board for permanant applications
-
You forgot the part of how to upload new programs after you have the bootloader on. That makes the cost > $8
-
lol. You got it. Yea, I forgot to mention it, I'll add it.
