Joule Thief

@ jadaro,

In reference to your previous post...

" In addition to the attempt, I placed a neomag on the coil, and the voltage output decrease significantly.  It appears as though bringing a permanent magnet near a BO-JTC coil setup is decreasing the performance of those coils when they're being used as an oscillator. "


In disassembling a microwave magnetron I found 2 toroid magnets (failed to note the polarity configuration tho)...considering that it and the j/t both deal with high frequency, it stands to reason that 2 magnets in various arrangements would have to be similarly applied to the j/t before giving up on the concept.

Hope that is of value somehow.

Regards...

I believe that the magnets in the magnetron are to direct the microwaves much the same way as is done with the electrons in a cathode ray tube.

@ jeanna

Thanks for your feedback on the 3" toroids. I think I will try the same design I have been using on the 2" toroid and see if that will also work on the 3" toroid.

@Pirate,

Thanks Bill, I had a lot more "stuff" to add to the cartoon but there just wasnt enough space on the A4 ha ha, ohhhh I love it.
You betta get a home Weather Radar to dodge those storms, or string up a wire high on a balloon, then connect it to earth via a battery charger, I hear it will make thunder storms a bit less powerful.

If you havent got a lightning arrester on your ph line, get one, any strike on your line even if it is 10mile away can travel through to you, if the strike hits your cable, then it's buy bye modem PC.

Actually, I have seen what lightning can do, it struck my Dads workshop main switchboard one night, there were black holes blasted all through it as big as your fist, what a mess, burnt wiring etc etc.

@Jenna:
   It is a known fact that a cold FL tube is harder to light than a warm one. One place I worked, we had to switch lighting so we could see in the winter just because of that.

@jadaro:
   The magnets in a magnetron are to force the electrons into a circular path towards the anode instead of a direct path. As they travel past the odd/even strapped vanes in it, it causes the output frequency. Each one of the cavities in turn resonates to the set frequency which is the output. On of the cavities has a probe in it which is used to extract to the outside wave guide. The magnets are N/S on the faces the best I can figure. I have ten sets to play with. The diodes were like $25 each and I get the whole thing for $5

   AND NOW, Please dont play with the magnetron out of its wave guide. That stub out of the end is the output probe. You will be bathed with about 80% of the input power but at water disruptive frequency. It cooks from the inside out.

This is why all cell towers carry a placard  at ground level warning you of radiation hazard.

maybe now this explains all that UV...  out there hummm 

liveing inside a micro wave..    cooking us and the earth ..

my question would be   what are the results of this ... on a cosmos scale

would it have the potencial to cancel the incomeing waves that holds the plannet where it should be 

and if it does .... well  oooo better fix it !!!!!

ist!

just wondering a lould ... as per usual
