Joule Thief 101

[MileHigh]

I suppose that I could go out and get a post and a magnet and wrap a coil and make the magnet wobble on the post and get all excited and convince myself that I am doing stuff that is "not in your books."   

Good luck on your little junior college Physics 001 summer school lab experiment.   

P.S.:  If you get close, then watch out for the dreaded "MIBeach Ball."

That Great Attractor was a real card was he not?  Got to love an alien with a sense of humor.

Was a great movie.  Lots of neat little doo daas in Tomorrowland also. Project Almanac was cool.  Off topic, lol, American Ultra was real cool.

  If one places a wooden instrument, such a violin, guitar, etz... a couple of feet of even some yards away from another such instrument. Then play a note on the first instrument, the second instrument will resonate (re-sound),  even if only slightly, at the same note, or frequency. Right?  Now, If you play a chord, instead. The second instrument will again resonate same as the chord played by the first one. All of the notes of the chord will resonate same as the first instrument. 
Therefore, resonance and it's harmonic overtones, is a fairly complicated subject to discuss, or argue if you must.
 
  However, Tesla's ideas about "resonance" are not the same, as what we are taught even today on the subject.
And had more to do with the unimpeded flow, from one thing to another.  But, I'm not good at trying to explain it, like he did.
  Sorry, I'll leave it at that.
  I'm Not trying to ruffle any ones feathers....  Just tossing out some ideas.
  Thanks for listening.
