Hi All,

What about cutting large Tv yoke in half, would this work for the YT toroid? I successfully cut one with diamond cutoff wheel mounted on pneumatic die grinder while back.  It is very dusty job so do it in well ventilated space and wear mask...  Soon I'm going to wind one so I post the results and pictures.. ;)

Has anybody made a joule ringer with the base on the transistor disconnected?  Where you would normally put the resistor - just leave the circuit open at that point.  I have been seeing some very interesting results running my new joule ringer in this mode.  I will post a video update soon. This new design is super easy to build using standard parts.

Hi all,this is my first post and I am not sure if I am in the right area.
I need to say "Thank you" to Lidmotor for suggesting "use anything you have".
Now this is a 273-1365A Radio Shack transformer with MJ13007 trans,orange 225ppw 100DC cap and a decade/resistor wheel.Running off an auto battery 14.8v-my meter says 12.6v.
After being annoyed about the price to import(Melbourne-AU)Lights of America LED's I came across GU10.
Have any of you worked with GU10's?
I did some comparison tests with CFL's also and am now sticking with GU10's.
I am posting this picture to show I am replicating and need help/advice.
Is there better transistors and caps to use in these circuits?
I am waiting for some IRF530's to arrive and will try them with an inductor on the base.
I have also ran this circuit using a AA1.5v joule thief and 5v cell phone chargers,but I might stick to auto battery as I may change to 12v SLA for Solar.
Any help kindly appreciated,
Tim.

Just wanted to say thanks Lasersaber for the super efficient circuit.  I've been using it for battery testing and it works well. 

Also, I tried another coil for the driver (as I'm playing a bit) that seems to work well. It won't turn on at quite as low of voltage as with the ferrite in your circuit; but seems to work through and past LED conduction?!  I posted a first video just to show what's going on, but ya;  need to test some more. 

It shows the same basic circuit. Power in across a 10uF, and same 2n2222a and same 5M dual audio. I changed the cap across pot. to 10pf.  And these two flat coils are laid for opposing winds.  I say in the video what's connected where for the coil.

I'm going to play around with some other things, but I wanted to post this curious effect too. 

Thanks

I added a dc converter- rectifier output to the circuit I posted, that seems to work well!  I believe I give all the values for things in the video.  But I was able to light 5 leds (startup min.) at .9v and at 3.6v it draws about what 1 LED is rated for.  Seems to allow for a very smooth and fairly regulated output (about 1v variation on the output with about 4v input change.  I didn't point in the video that there's an extra 640mv drop across the 1N914 diodes in the rectifier
  I dunno, maybe adding this onto some of the JT circuits can help for powering small loads that need DC.  I imagine you could run pulse and timer circuits off it, who knows.  At least it's not clamping the V rise across the CE bridge anymore, yay!  just playing around I supose.

maybe it can help.
Thanks

Thanks for the new video!

I was anxious to see if you could get it working without a Square BH or not, but Yay!  Ty for the circuit link also! I have a larger transformer that I've been playing with, but this may be a great way to connect it instead!  So, far I was just running a normal JT connection with 6 LED's on the secondary and either 2 LED's or a battery (yup charging) on the primary @ 1v.  (Edit: posted vid of this setup before tearing down: http://www.youtube.com/watch?v=A3qAGGhEfFc )However, I definitely will try this method of connection. 

Great Job Laser!

PS- I don't want to make a thread and not sure where to put, but I made a video of a JT for low power (380mv+) that does not need a toroid core.  I figured it would be good for those who can't find toroids or have trouble.  I personally hate winding them.  Anyhoo;  http://www.youtube.com/watch?v=pjvkUFBog-o

Thanks

Lasersaber well done !

Here is his new circuit:

http://laserhacker.com/SuperJouleRinger2.html


P.S: Why do you use this bifilar coil for the primary and in your circuit
diagram it is not mentioned ?
Does this not connected primary coil have any effect like
a stray capacitance or stray inductance ?

Any current measurement for the input yet ?

Many thanks for your great work !


Regards, Stefan.

First replication!


http://youtu.be/0eWhB76toq0


I use bifilar because it spaces out the primary wire better.  I could also use string.  It also gives you the option of hooking it up as a standard joule thief if need be.

Nice replication of Mopozco !

Lasersaber if you use the standard bifilar design with these 2 interwooven primaries
connected in series. does it get better then and will it use less input power
as these 2 coils will have more stray capacitance which can store more energy ?

Many thanks.

Regards, Stefan.

Just wanted to say I was able to replicate the super joule thief 2.0!!!  Yay!

Takes a bit of fiddling though.  I tried a TIP31 (not c) and it didn't get a full light.  I have the correct on order though, so I ended up getting a 2n3055 to work well.   The iron core has a bit more loss and doesn't allow as high of frequency, BUT it is extremely quiet.  I think the video shows everything for input and such.  I just wanted to post my "first light"  with this before I start playing ;).
http://www.youtube.com/watch?v=tR6pB30DgdM

Coil from Laser 88mH primary 480mH secondary
Feit Electric 13w Compact Fluorescent daylight bulb (not seen a PC fully light before with a JT)
Input @ full light 16.5v @ .47ma (about 8w) lighting 13w fully!
I also checked the Fo of the circuit and it's around 1-1.5Khz depending on voltage.

I figured out also how to start oscillation when you have troubles, so ya' don't have to shake wires.  When your at or near the oscillation voltage (was 4v for the TIP and 10v for the 2N), you just have to "bump" the base with your hand.  The added capacitance is enough to start the oscillation.  This is the same reason peeps put a cap across the resistor to the base on a normal Joule thief. 

I'll do some more playing around with things and see what more I can find.

Thanks again LS for the great use application of a feedback oscillator as opposed to the normal JT blocking type!!! Great job!

Last, if you play around with these circuits, it seems the highest risk is the B-E junction roasting.  So be cautious of that. I mention the reasoning in the video.

Thanks
