Re: Piezo tubes
I had the same experience with them. I ended up ordering some from JLI but

Re: Piezo tubes
Hi Jack,
I've had some great results with approx. 25mm diameter, 20mm length and 2-3mm thickness.

Re: Cheap USB powered condenser microphone. Need advice on design.
I did a tear-down of a $14 USB mic here:
