Joule Thief

[jeanna]

@Artic Knight,
I just want to share a design idea that has worked nicely for me.

In the craft dept of the wall mart there are placks. These are unfinished hardwood boards in 3 sizes around 6" x 8".
If you make your joule thief circuit and stick it onto one of these placks you have a nice looking and moveable device that can light various batches of leds depending on where you want the lights to be on.

A youtuber named the daftman showed many folks about using brass nails to mount a good looking circuit on a small board when he first made a bedini ssg circuit.
I recommend having a look.

Enjoy,

Oh, lately I have been seeing what can be done with almost no current. It is not as interesting, but could come in handy.

so what are you guys working on these days? have a few crazy ideas for pushing the joule even more efficient or just trying to light more lights?

Artic_Knight

really neither.
I have never  really  been into the efficiency of the JT
I am more into the impuses it makes........and what can be done  with them.
Now  that  I have a high  voltage candy cane  coil I can  experment  with wireless  transmition.
I project that I have wanted to do for a while is a wireless charger for my cell phone. 
I plan to use something like an AV plug with a piece of copper about the size of the battery as antenna.   I need to find some very small diodes......then I will  be ready
I plan  to put  the  wireless charger in  one of those  disposable food containers........I will attach  another larger copper sheet to the inside of the top of the container......... it will  be hooked to the secondary .......it  will be pulsed with over 400V
Each  sheet of copper will act as one plate of a capacitor ,
I do not want to fry my battery ......so I will adjust the charger to take  around 4 hours to charge the battery.......
If all goes well....once it is  done  I will  just toss my cell phone  onto the top of the container...and it will  charge up.


That is just one little project........I got about a dozen others..... today I spent  most of my free time working on  molds for black  iron or  bismuth  cores.......they now  need a few days to dry.

I think tomorrow I am  going to try to make some progress with my version  of a bedini motor.

  Hello Anybody !!!   I have charged up a 400v CAP to around 80-90v with a Biff wound toroid,
Can I charge this cap to 400v with a secondary coil on joulethief, if so, where do I connect CAP to charge it???   cause I kind of tried and does'nt work

Hi everybody,
I answered a pm from freepow on this same question.
I figure if freepow wanted the answer, others might as well, so here was part of my answer:

You need an enhanced bridge to collect lots of HV from the secondary.
Make or use a full bridge and connect it to the secondary wires then add another diode to each output in the direction of the polarity to be found there, and watch out!

This is how MK1 taught me to determine how high the HV was on my secondary.

(I am using this enhanced bridge to spike-charge a 12v battery. I cannot get it to charge but it is a great reconditioner for the 12v.)

@freepow,
just because you have a 400v capacitor does not mean you will be able to put 400v into it.
If your joule thief output is only 75v, then that is what you will be able to collect in the cap.
