They talk a lot about filters and a 'network'. They also look for 'something' in my basement. I surmise they are attracted to the area where I have run my Tesla coil on occasion as part of these experiments with EVP/ITC. I am attaching a crude block diagram of this set-up. Thanks for your comments and feedback, Dave P.S. The signal flow in the picture is from left to right. The audio samples from the auto-tuning radio moduate and vibrate the oil lamps wick, mantle and flame. These vibrations are picked up by the photomultiplier tube and converted to an electrical signal (sound). A pre-amp may be needed to amplify this audio signal from the photomultiplier tube and feed it to a conventional high quality analog or digital recorder. The optical microphone has unique properties as an audio filter. Have fun with this design, it works! Attached Image (viewed 799 times): Last edited on Oct 25th, 2007 02:54 PM by EVPDave |
