Breadboarding an Arduino • Luminosphere on Etsy.com 

Posted my original prototype on Etsy.  here's the link:

Luminosphere for Sale – WAY OVERPRICED

I think we all should put our stuff on Etsy!

Maybe ITP was the place for me?

If you weren't aware, the brain of the Arduino is just an ATMega168 microcontroller which is sitting in a cradle in the middle of the board. You can pretty easily pop that guy out, and replace it with another identical chip.  Now, the chip DOES have a "bootloader" on it, a small program that allows it to communicate so seamlessly with the Arduino environment. 

Here is why this is so exciting- SparkFun sells the ATMega168 WITH the arduino bootloader already burned, for just $4.95  …. i hope you can see how awesome this is, I am going to be able to bring my $42 Luminosphere down to just $12 with that guy!  You do, however need a 16MHz external crystal (clock) and 2 capacitors, a resistor, as well as a 7805 voltage regulator… so maybe more like $15. But still extremely worth it.  Hope someone finds that useful.  I just ordered a few ATMegas and crystals, if anyone wants to try this out.
