Buddy,

Do you know if the Ten-Tec kit produces a pulsating or modulated noise? 
That feature really makes the noise bridge much more useful.

I found the kit from Ten-Tec, and it really is around $25, but with no 
enclosure. I wonder if we can find some bored person to build up a few of 
these for us?
