Joule Thief

Hello drodenbe,

I noticed that your coil was wound on your source battery.  Very interesting and I have had this idea before but never tried it.  If you have a 10F radial supercap could you test your setup on this?  I would be very interested to see if a supercap, which has much less energy density could run this crt and charge batteries while lighting an LED.  This would further demonstrate the uniqueness of your crt.

Great work!

Hello stprue

wow! Really nice to see some one really looked at my schematic and paid attention to detail.  Yes I also had this in mind.  I just happen to have several supercaps in my inventory.  I have a 2700f at 16.2 volts and 10f at 24 volts.  I am retired and usually have 4 or five FE projects going at the same time.  So yes I will set that up today as we speak.  I will know very quickly if it  works or not.  As I said, I can read 5 places to the right of the decimal so it tells you very quickly what is happening.  I bit the bullet and bought a lab quality HP voltmeter.  I have been building these circuits some 6 years and got real tired waiting days to see if I was going in the right direction.  So I can, do better measurements!  Been down this road too many times.  I have many very pretty circuits and designs that don't work!  Thinking about making a museum to demonstrate what not to do!  I will get back to you on this in a few days.  Would not want to rush things and get some incorrect readings as you know!        Ps. Decided to wake back up and answer questions with people interested in building and testing new ideas and not just commenting on others work b4 they them selves have tested the idea.  Sometimes things are not what they seam!  Thanks!

Thanks for the info.  If you look closer you will see the difference between yours and mine.  The battery is the core of the coil.  The coil is not wound on a standard core as the others.  The battery has to be inside the coil.  Also notice I did not claim OU.  Also if you will notice I stated that in that time I ran a jumbo Led and charged several batteries from .6 volts to 2.4 volts being the batteries were in series.  I think that the fact that I was doing work and not just running the oscillator speaks for its self.  My equipment reads 5 places to the right of the decimal.  There fore I don' have to wait a month to see if my voltage is going up or down! As I said I am not going to make a bunch of noise.  I just thought I would share some of my 40 years experience as an Eng.  So Thanks for the info again, Now I will go back to sleep!  Thought It would be a mistake and my fellow Engineering friends were right.

Signed:  never to trod this road again.

@drodenbe: Why are you so angry? You made extraordinary claims. Extraordinary claims cause scepticism.

In case there is some value in your claims you could give as some more proof and some help to facilitate replication. Photos of your set up would be helpful too.

People should be able to replicate your circuit and you should be prepared to answer questions and to sustain some criticism and doubt.

Then may be, you get the attention you seem to want.

So, do you want to see people replicate your claims or do you want to keep a secret?

Greetings, Conrad

P.S.: I did not say, that the circuit I showed is the same as yours. My point was, that careful measurements are necessary. Many digits after the decimal point are not helpful in case one measures at the wrong place.

Hi Drodenbe,

Unfortunately I came late and by that time you deleted the schematic. I would like to see it if you do not mind. Could you upload it again? I always like to learn.

Thanks

Great, I look forward to your results!

Those are some massive caps.  I have a 2700F, but only at 2.5v.  Electronic Goldmine had a sale at one point and they were charging something like 10$ US per cap.  I too need to get a better meter and was actually looking today, but even a lower end agilent cost a couple hundred dollars.  I just dont have the funds for that right now. Anyway, have fun testing!

P.S. Re-posting your schematic will assist those wanting to replicate.  There are many skilled builders here that can be very helpful and there are those that are not.  You must deal with both at this forum.
