Joule Thief

[Mk1]

Hi everybody,

Here is a little description of how to make the MK1
It really is only how to make the secondary part.
MK1 describes 3 ways to make the primary part. I personally do not find them very different, so I do not want to bias this, by choosing one.

@jeanna


This is so important , it dictate the current phase , but i guess you can't really see that on a scope and your reticence to use diode , doesn't help you there because there is stuff missing in your knowledge . You would have made greater progress if you had tried my directions on tuning (always adjust pot), but that stuff is still missing , i can't address this you can.

And don't get me wrong keeping the ac is fine by me , but learning first .

Coils ,battery led(diode) are bi polar , so you need to see them in both direction.
It will help connect secondaries together.

I scope on a coil will tell you how much there is , but dose it tell you witch end of the pickup coil is the output or input.

I know you don't like gray area but , minimizing unknown ignoring them and sticking to sure bets , got us here today looking for the missing parts  , so lets not go there again .

Plus those are magnetic 101 info.

Btw the difference between the regular mk primary and the X2 is not voltage but freq...
This is why , every time you change the design on the primary adjust the base resistor.
Otherwise you are seeing and learning what you should , and are unable to determine real improvement .

@IST
I agree too, those words are good advice.

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

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

IST, you gotta frame that pic, they are treassures.

ooooo gotta watch out we don't use too many smilies, they turnintoheadroads 

At the moment I am making two work benches, big long one for building my JT's and bedini's with a top shelf for the power supplies, Counter, crows soldering iron and 6 way power board.

Other one for a couple of Laptops I have, I need kitchen space real estate lol.

Just thought of another one to make, groan, a wide Battery recharge shelf, with a small cabinet to hold all the good rechargeable batteries and their test stuff, and a place to put the batt powered drills on to.

@All,
I can see the 3 phase JT being born, just look at it, Delta connect configuration, then mabe a Star configuration, phew, energy approaches.

@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 ...

@electricme


Delta and star , i personally think they are nice for motor ,but there is nothing exciting or efficient about them , but they have great names must be a easy sell ...

@ThaNOP,
Thank you Actually you discribe my place here nicely ha ha.

Same here guys . I'm a pack rat and hate to throw stuff away and when i finally do i miss it and either go buy it again or dig in my local Treasure Dumpster and pile it in a a tine 10 x 12 so called "room" being sure to leave a one to two foot path . I am not ashamed anymore !
@Jim . I loved the cartoon and am using it as a desktop background.Cant wait for a final  picture . make sure you put bill and jenna in there ;)that will be a prize.
