Well keep in mind that if memory serves, you don't need multiple threads 
to drive those things.  You set a value on the port and it'll stay there 
until you tell it otherwise.  I could be wrong of course - I haven't had 
time to play with them yet.

What chip did you find for driving the air-cores serially?

It's a good reason to keep some of the ATMega328 PDIP based versions of 
the Arduino handy.  If you cook it, you just stick the bootloader on a new 
one and go.  You'll need to build an ICP cable or have an STK500 (or 
similar) programmer to burn the bootloader on it though.

Political correctness is a doctrine, fostered by a delusional, illogical

holds forth the proposition that it is entirely possible to pick up a turd
