I agree, that was an excellent link! Thanks for that Dave! It is dead on....now I just have to understand how to replicate it.....and what that entails.....I really liked the part that said:
Yes, lots of good info at that site. I found the videos interesting as well. I did considerable testing with a Tesla coil back in 2004-2006. I still use it from time to time. The noise they generate in the radio spectrum is intense. It nearly always knocks my computer off line as well. I would say if the coil gets too close to electronics they could be damaged. The coil I use is small, maybe twelve inches tall. I purchased it in the 80's from Edmund Scientific.
I also did some testing with spark gaps and arcing. I found I actually made a video in 2007. Poor as it is it shows the noise and light generated by an arc.
I find the best way to 'listen' to arcing noise is to use an optical sensor to view the light-wave portion of the arc. This filters out some of the distortion that is created.
If you decide to use a Tesla coil keep in mind it can run for short periods of time. The spark gap produces considerable heat. Also, if you have neighbors who listen to AM radio they will come looking for the source of interference, similar to the ham tracking down noisy power poles, ha!
