Plasma Oscilloscope

Postby Timefoldsup » Tue Jul 08, 2014 9:49 pm

Has anyone else noticed that when your coil is in operation, the audio waveform is visible in the plasma discharge? I see a "freeze frame" effect similar to what can be seen on my oscilloscope. In the sparks I can clearly make out the audio waveforms. As I increase the audio frequency the waves or peak to peaks gets closer together as I decrease the frequency they get farther apart. You have to get pretty close (4 ft or so)to see it well so be very careful!!!! A well grounded sheet of expanded metal or even a full circle Faraday cage is a good shield to stand behind if you want to get close enough to see this safely.
