Joule Ringer!

[shylo]

Hi Stefan, Yes I see this with the caps I'm using as well ,it's too bad we can't increase this recharge effect,or can we? Is there any way to use larger caps to help in the recharge of a bank of smaller caps???.........thanx for any ideas.........shylo

Dear All,

I have done a rough Area comparison with the Output Power Curve and the Input Power Curve with the FLEET Prototype A.  The screen shots were done by PhysicsProf on Jan 22, 2011.  It is obvious that the COP is greater than 1.  Please see reply 350 on that thread and the following link:

I am sure that the Joule Ringer undergoing the similar two oscilloscope test will also show that the true COP > 1.

Great Work and God bless you all.

Ok now it seems you managed to get others to see the potential of the Joule thief

Good work ! But now we need to address the real issue here .

You showed poor judgment in changing the name of the JT to your fleet shit , this doesn't give you the right to steel work from others and get the credit for it .

I personally think you did a good job , because no one would have done what you have done , lets clarify that you did not invent the fleet because it was already there and called the Joule thief , thousands of people put there efforts together for a common goal , and that goal was no to provide you with retirement money , we are in this mess because of people taking advantage of others , prove to use you are not one of those , stop calling the JT something else then a JOULE THIEF .

I must say i feel cheated by the fact that you try to steel the JT from the people that  conceived it , i personally put 2 years of my time in this project , and that was a gift to the world not to you , you are part of the world and deserve access to it but not to take it as your own , you may think you did great by proving what most of us know , the only problem in doing that is that you removed our anonymity , now we will be a target , more work for everyone fighting all the trolls , our relative peace in conducting our experiment may be a thing of the past .

Now you know why others did not pursue the cop verification , but since you are simple man you did not catch that , i tried to tell you !

All and all , thank for helping the JT cause .

The circuit became a little bit better, still double triggering of transistor!

Sorry, nothing spectacular, but I could make the circuit with the little fly back transformer and the 15 Watt CFL at 12V a bit better.

It needed a 1nF capacitor parallel to a diode in between the trigger coil and the base of the transistor to give more light for the same power supplied.

At 0.6 Watt the CFL starts to be a useful lamp, may be as a reading lamp. At 0.15 Watt it is just nice to look at (nice yellow hue).

There still is a problem: the pulse from the trigger coil does not cleanly switch the transistor, a double triggering occurs.

The scope shots on the left are done between GND and the base of the transistor, and the scope shots at the right over a 1 Ohm shunt in between the drive coil and the collector of the transistor. One sees that the transistor does not switch cleanly. The diode and even better a 1nF cap parallel to the diode (in between trigger coil and base) does shape the trigger pulse better, but still not good enough. The diode is important to avoid a high negative voltage on the base (base below emitter is very bad for the transistor).

It looks like the current from the trigger coil brakes down a little bit when the transistor starts to open, hence not a clean switching. I think one needs a more powerful trigger coil (more windings) to overcome that. Which is difficult to set right in a salvaged fly back transformer.

Be aware that the circuit is very sensitive. It is optimized for a 12 Volt battery, any other Voltage would need readjustment of R1 and C1 and higher Voltages pose a real problem, because the transformer is not built for that, it will shorten. Lower voltages (below 7 Volt) do not ignite the CFL because the step up rate of the transformer is too little.

I understand why LaserSaber built his own transformer. This is the only way to control all parameters of this circuit and to move forward.

I hope that others will try the diode and parallel cap in between the trigger coil and the base of the transistor and report their findings. Once I get more fly back transformers, I will try with them.

@Lawrence

Please post this topic in the Joule Thief board.
Who did these measurements and are these from a multiplying scope,
so power is calculated on the fly ?

@conrad´,
well done.
Maybe you can still add one or two 1N4148 diodes in series with its cathode from the basis
of your darlington transitor to the ground, so the anode will be at the ground.
This shunts away all the negative spikes at the basis and might help to
make the current pulse better inside the darlington.

Regards, Stefan.
