August 25, 2004

Spent a lot of today (yesterday? since it's now 12:45am) working on my little
homemade microcontroller board. Seems when I put a AT90S8515 in it, it works great, but when 
I used a mega8515L, nothing happens. The mega8515 worked fine in the dev
board too, so finally figured out that my 3.69mhz crystal resonates correctly
with the 90S8515, but not the mega. They are apparently pin compatible chips,
though the mega has "slightly different electrical characteristics." Damn.
So now I'm thinking of ordering my own board from ExpressPCB.com. anybody
know any other good places? ExpressPCB has a nice simple free CAD product too,
so I got started designing (err, translating) my board, here. 
I know, that design sucks, reading up on it now =)

(this board is basically a many controls -> rs232 serial interface, that will
effectively be the foot controlling board, for the Jesusonic)

The last jams Brennan and I had last friday (040820*) were awesome. A couple
of good songs in there, repeated over and over, too.

not sure if I ever posted this, but it turned out the mega's config bits were set wrong. oops.
