Slayer007 was getting similar results with a similar circuit (see Joule thief thread). There seems to be something happening that is not well understood.

Xee2:

Your statement quoted above is an example of one of the many reasons I have great respect for you.  Even with all of your knowledge and electronics experience, you are still willing to keep an open mind about stuff that "is not well understood".

I have several friends that are electrical engineers or electronics technicians and, they "know" everything and there is no more room for learning.  All of my experiments to them have just been "some form of anomaly caused by my screwing up something because the book says that is not possible."

I am glad you are with us on the forums and I just wanted to say that.

I am sooo glad I bought that meter.

Did you ever work out that odd reading on that toroid of yours?

After the roof is done, I could wind a little toroid like that and see what kind of reading I get, if you have not found out yet. It sure would be an easy way to get lots of Henries if you think they are real.

My inductor/capacitance meter is second only to my volt meter.
Also test any capacitor you're going to use in a resonant circuit.
I've found many capacitors are a little off and that difference could be adjusted with the inductor being changed a little.  This is where that resonant calculator comes in handy.

gyulasun was going to measure the inductance of a toroid to see what he gets.  Probably won't know for sure if this turns out to be an easy way to get Henries until it's tested in a circuit.  Our meters could be doing something "wierd".  But you're welcome to test a bifilar wound toroid to see what your meter says.  I only found this to work with toroids.  Probably because the flux stays in the core of the toroid would be my guess at this point.

I would agree if the positive was connected also.  Being only the negative is connected it performs differently.

Also, isn't the resistor going to want to use the current and drain the capacitor?  With the inductor replaced with the resistor I don't get any charge in the capacitor.

I now removed the inductor leaving just the capacitor. The capacitor is charging all alone with just one lead of the capacitor connected to the negative side of a 9V battery.

If your circuit is just a capacitor connected to a 9V battery it will charge the capacitor slowly.

If you add a 6 inch piece of solid insulated wire to the other side of the capacitor it charges faster.

And if you stand back and look at this picture you'll see the same setup as an aerial system...  antenna to capacitor to ground (neg. battery term.).  This is just a miniature aerial system.

I have checked my inductance meter with capacitors and a resistor
plugged into the L measurement ranges and was surprised a little.

The L measurement range is 0-2mH, 20mH, 200mH, 2H and 20H (Maxwell MX-25 304)

If I test a 1uF (non-electrolytic ERO MKT 250V) capacitor in the L ranges,

the display shows  -0.127mH in the 0-2mH range
                   -OL      in the 0-20mH range  (OL=overload)
                   -6.1mH   in the 0-200mH range
                   -0.061H  in the 0-2H range
                   -0.61H    in the 0-20H range

This 1uF capacitor measures 1.032uF in the normal 0-2uF C range.

If I test 0.1uF (non-electrolytic ERO MKT 250V) capacitor in the L ranges,

the display shows -OL up to the 0-200mH range and shows
                        -0.063H in the 0-2H range
                        -0.63H  in the 0-20H range

This 0.1uF capacitor measures 96.2nF in the normal 0-200nF C range.

If I test a 1.6 kOhm 1W rated (metal film) resistor in the L ranges,

The display shows OL up to the 0-20mH range
                         2.2mH in the 0-200mH range
                        0.004H in the 0-2H range
                        0.000H in the 0-20H range

If I test this 1.6 kOhm resistor in the C ranges,

the display shows OL (instead of 0.00) in the 0-20nF range
                     1.3nF in the 0-200nF range
                  0.001uF in the 0-2uF range
                   0.00uF  in the 0-20uF eange
                    00.0uF in the 0-200uF range

This resistor shows 1.608 kOhm in the normal 0-2 kOhm resistance measurement range.

So I consider all this as erratic behavior of instruments and close down this from my part.

@gyula, thank you.

I'm try to set up a circuit to see what happens in real life.
