Ooh, ooh! I was going to start this discussion, but you beat me to it.

Good youtube videos I have found:

Then there's lots of people who take trashed-out yard-sale guitars and perform fiendish experiments...

Just now got back from checking out a 24-hour grocery store for material (note to self -- you have to grow up SOMEDAY. Maybe not today). In the "Kitchen supplies" section they had drip pans for stoves that looked promising -- light-weight and CHEAP. Alas, the smallest of them was still 7.5" across, and even the biggest box I have isn't quite that big. I could easily build a box AROUND such a thing, but would't that break a fundamental rule of the CBNation? Or are there, in fact, NO rules?
I'm off tomorrow to a hardware store. It seems to me I might be able to find a cheap shop lamp with a reflector that could do the job...

Umm... yes. Those are piezos. I might order some.
But do you know where we can get resonator supplies?

hey. so i just built my first cbg...i made it a resonator by using two cans. i am just about to go out to the shed, to set it together and test it for the first time :D
what i found out is that you shouldn't worry too much about soundwells if using cans, just make sure whatever you use as cone is able to vibrate/resonate freely.
i still have an unsolved question, as to where place the piezos? i am thinking of combining two piezos and packing them in to sandwiched wood and using them as biscuits... not sure yet. if you have any suggestions, would be appreciated.
cheers
