Michael,
Thought I would share my v.1 device built using your board, some code you provided, and a few additions, and hacks
I will try to get pixs up in this thread a bit later on...
In the meantime, here is a video shot via an iphone so the sound quality doesn't really do it justice, this thing is loud and distinct out to 120ft
Enjoy, and thanks again for answering questions.
