Joule Thief

@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.

The fact is we are being bobbarded with microwaves from towers to satellites . the energy output is minimal on one but take that and multiply it by approx 200,000 and you have us cooking . look at all the cancer . this is a main cause i fell . you can extract that energy with a tuned cavity like the magnatron  use a dish to focus the singnals on the dipole of the magnatron to capture the radiation already in the air and see the out put on the magnetron input as volts  . I have played with magnatrons and am not scared of them . you can light fl tubes up with it  for 100's of feet and shield it with a directv dish If you play stay behind it. its very similar to a gigaplexer which is like a radar cavity on your radar detector  except we hams use it to talk thru . 1000's of watts  directed with a wave guide or "DISH" .  . WARNING . you have to be experienced Licensed radio Technician and Electrical Technician before you even try to hook one up and attempt to Broadcast / modulate with Microwaves .
Good to know to got one apart . I have wondered what kind of magnet that was . Is it ferrite or Neodymium rings ? If its super strong its probably an alloy of Neodymium /cobalt iron .. Edit*** found the answer they are  samarium cobalt . and some tube in them have the magnets inside the tube or at least there is a patent for it (reminds me of Sweet's vacuum tube using barium .cobalt magnets to extract energy from his vacuum tube ) This warrants experiments with two magnets with the Jt torroid in the middle . I think it raises the frequency higher than most transistors can handle therefor the jt light usually  goes out or gets dim when we place a magnet near a torroid.Just need a microwave transistor . i have a few and need to dig them out . they look like a can transistor with flat leads .

Hi Mark I will get to that in a minute.

@xee,
This is what I can say about the comparison of stprue's and mine.

Quoted text is from stprue===
no rectifier
======
I should remember to fix my mistake with the battery rail caps.
I put 2 47uF caps in series thinking I was adding more farads, but they should have been in parallel. I forgot to fix that again this morning.
tomorrow is a new day!
---===
The base resistor is ~90ohm
Tuning the pot got the pickup volts up from 80v to 450v.
======

13Base turns
3 collector turns.
24 gauge tele wire
mine would not even turn ON until I had more than 8 on the base, and when I reversed the 3T, for the 13T It started to sing and... 450 AC volts was the results. Peak to peak.
======
Mine is newbie wire 24 gauge.
===
I asked about the bridge and he answered...===
In the end he replied with:
===
This is true in part for me too.
I found that amount of difference from 80v Peak to peak went to 450 volts p2p.
BUT as I have said, mine would not even turn on until I had 13 turns on the base.
I have 2 3055's that I wired up and tried with this too.

I was wrong about two things my POT was a 500ohm set low, I'm not sure how low, and my wiring was..

3 Base turns
15 collector turns.
22 gauge mag wire

265 on Primary
24 gauge mag wire

I used the thicker gauge because I wasn't sure if 30 could saturate the core enough to get the desired effect, but my next one will use thinner wire!

@Jeanna

My AC voltage with this biggo is like 47v, I'm not sure if it's my set up or the way I wound it or maybe we have stumbled upon another benifit of the MK design! Hummm

@ALL, Time for another CARTOON, who R the stars this time  he he

lol
nice drawing.
it look way more cleaner then my work bench...

i wish i could take pictures.
just to give you an idea, think of a scrap yard but filled with electronic junk pilled here and there in a 8' x 12' area.
with books, old computers, computer parts and accessories, almost all over the rest on the basement.
i am cleanning up tho, slowly...
i recycle everything that can be.

thanks for your previous comment.
but know that this house of knowledges is as crippled as my basement.
so you better do your homework and cross-reference what i am saying.
just like you should do with everyone informations.

[innovation_station]

yep i do agree with you the nop


must always check

im well aware that some things i have said in the past were not correct  this does not bother me tho as we are all here to learn ...

learning is accepting where we were wrong ..

but  agin nobody did it alone  NOT EVEN TESLA ...   he had a team ... 

we also must realize that where our thoughts come from then we will realize our work infact is not our own ... 

here is a pic ali drew fom me to give to you all   

ist

nice jim    those cartoons    peace bro!!   almost there ....

@ist

There are some old tales from the Celtic energy in knot , but this looks even more familiar, lol , its a triple coil orbiter like ED but with a third coil ...
