Well, this is my first thread in the Exhibition area, and I hope it's a good one
I caught some ATmega644s on eBay for a steal, so I just had to make something. I've been working for a few days on putting this together; It's not exactly pretty, but it certainly works well!
It's the ATmega644 (no, not the ATmega644p that the Sanguino uses), and is running a modified version of the Sanguino bootloader (I didn't modify it, it comes with Sanguino software). I've tested all the I/Os, and the work.
