Rolling Echo

The happier side of the last post is that I used the PP3 battery for a new design. I have been thinking on it for months. Cape Town has a noon day gun. Years ago now, this gun went off as I was sitting below the face of Table Mountain. For about ten seconds, the echo rolled across the face of the mountain. I tried last year to record this. In spite of using a stereo CD-quality recorder, I didn't obtain a good result. I decided to design my own stereo microphone, therefore -- using a PP3 battery. OBSERVATION: I have tested the microphone successfully, but not for its ultimate purpose.
