Someone's RFC really needs to address the worldwide need for a sarcasm font.. or wry smile font.. hehe
The Arduino is of course ready to go out of the box.. which compared to the Boarduino (because the Boarduino is a kit, and uses an external USB-to-RS232 as well as RS232-to-TTL bridges, and the RS232-TTL is also a kit) is up and running sketches within minutes of taking it out of the box. The Boarduino I purchased as a kit, mainly because it had been far too long since I had done any component work, and needed a little soldering practice. By the time I had put together the two kits, made cables, and all that fun.. it was a solid few hours until I ran my first sketch- but that was time well spent in my case.
From a software development standpoint, the Duemilanove was of course easier to "get going"- but I think that I actually learned more at the outset by assembling that Boarduino myself... there's no way I could work with these SMT components on the Duemilanove on my kitchen table without going blind...
Now, back to optimizing FFT code for the updated spectrum analyzer.. just a confirmed junkie getting a fix of the Real Stuff
