Joule Ringer!

Lasersaber! Grear video and great job! Thanks!!!!!!

Lasersaber well done !

Here is his new circuit:

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!

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 .

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
