During my freshman and sophmore years in high school I did tons of
electronics. At the time I was knowledgable enough to get third place
at the California Vocational Olympics in Fresno. It's been a while and
I'm REALLY rusty, but I think it'll come back to me. (I'm in my second
year of college now) I have no problem with this being a group effort,
all ideas are very welcome! I've got the chip on the way right now.
I'm also working on my TI Hardware Hacks Page. I'm going to make it the
COMPLETE site for anything to do with hacking the hardware! I'll try to
have it up by sunday, I'll post the url when I do!
Later
