Just something interesting that came up...
This post (http://ask.slashdot.org/article.pl?sid=05/04/25/230224&tid=222&tid=4) on Slashdot is asking for a simple and cheap solution for logging accelerometer readings a few times per second, to a MMC card.
Sounds like just the kind of thing that would be an interesting AVR project. ADXL202 + Mega8 + MMC card maybe?
I don't have time to do this myself, otherwise I might volunteer, but I thought I'd bring it to the attention of the board in case anyone else fancies pursuing it.
