Wow.  This sounds really exciting, that you guys are actually doing your 
own thing.  Are there any really simple/basic beginner sound projects 
around (that you guys have schemes for)?  I'm just getting started, so I 
know I 
wouldn't be able to handle the broad project that you're working on.  

I picked up a radio shack book 
that goes into electronics a bit and tried to  build a little chirp 
generator circuit (I can hear the laughter now :), but unfortunately, I 
can't seem to find any UJT's in this town!  Is there anyway I could use 
some other parts so as to not have to find a ujt somewhere, or should I 
start on a new project?
