Hi my master:

I has made a cheapest Standalone Arduino mini use ATMEGA8 and breadboard.
maybe you would like see it,here it’s photo on flickr:

If you think that’s funny enough to post on makezine’s blog,,,just do it.

Thank you very much for reading and sorry for my english.

Please no apologies – you’ve obviously never read my Mandarin ;)

Hmmm … I haven’t been keeping score on least expensive Arduino but this one certainly seems economical (depending on how much that breadboard sold for). In any case, nice label graphics! – Standalone Arduino mini pin mapping

  1. Really? Is that all there is to putting one together? Can we get some more details (required parts, how to program, etc)?

    Yeah, that’s the basic circuit. However, without additional hardware/circuits you wont be able to reset it (no reset button, though I suppose a wire that is touched to GND will do it in a pinch), or program it.

    I built one of these before without the crystal, and I was able to use the hex files that the Arduino software created along with a home made, parallel port programmer to program it. It was a difficult setup (I compiled GCC-AVR at the same time making it even more so), but quite the learning experience.

    I have to say, though, that I was disappointed with the performance without the crystal (I recommend adding it, even though you’ll have to burn the clock fuse). PWM signals are a little inaccurate without it (caused flicker with my test LED). And, I’d go with a home made serial programmer instead of parallel since you’ll be able to use the Arduino software to program it directly (no need to use avrdude)
