You might try using diode and cap as in following. This sometimes helps light tube. Also connecting one side of pickup coil to either + or - of battery sometimes helps (need to experiment on which side).

NOTE: this circuit is able to put out more power than Fuji board with only 1/5 the battery drain.

3 hours is great keep up the good work. I will still get the scope stuff to you from my Toroid I have been working non stop!

@all

I have a question that relates back to what a friend said to me yesterday at work. I do not know if this is true or not. But he said that once I reach a certain voltage / frequency point with my JT it will stop working because of the small gauge magnetic wire?

And that if I wanted to really push up the Current / Volts / Frequency I needed to re think my design. I did some basic research and I believe he is right. At a point the mag wire will bleed over and the higher the frequency seems to play an effect on the wire as well.

Using the LCR meter showed me the inductance of the wire. Well if you move up to 400 turns around 40 feet of wire the inductance gets really high. Thus you can get more Voltage with larger pickup coils true but at what cost in efficiency of the JT? How much harder is the JT having to work to push that huge pickup coil?

I can light 1 CFL from my big toroid from 1 AA battery the way I do it is with 1 fuji board attached to a pickup coil that has small turns less voltage just enough that will charge a small battery to the point that the fuji will turn on for testing.

It would seem to me that 6 smaller pickup coils on the toroid will give better use of the power produced from the JT?

So that is what my test is going to be for today. 6 pickup coils @ 2 volts rectified DC for 12 volts total. each running into a Cap that runs into a battery that then in turn goes to a Fuji board.

At that point I will attach a CFL to each FUJI and fire them up! I am sure this will work as I have tested the concept. When I have it done I am going to mount it on a nice panel and use it for mood lighting in my lab / kitchen

Here is a hand drawn pic of the concept.

Take care!

Congratulations!!!

@innovationstation
Thank you.

@electricme
Thank you.

@all
There are new break throughs.
I will wait till everything gets stable to try one of the new ways of lighting a cfl.
Right now it is still changing too quick.

Thank you xee.

I thought someone, probably you, had the diode/cap information to do this.
I will try it in a little while.

@jesus,
thank you

I had to go out last evening so I am not aware of how long the light continued to glow after I left the house, BUT

I left the house at 6 and I had got the light to start at 1:45 = 4 1/4 hours

So, xee2, this IS far more efficient than the fuji board.  4 hours 15 minutes plus more...
This is equivalent to 2 hours on the fuji board.

(The fuji drained the battery in 2 hours then after recovery one more then after recovery a total of one more. = 4, but only 2 on that first round)

thank you,

@jeanna

How are you moding your fuji boards? I am seeing 10 hours of light with a 13 Watt CFL. And it wil light 140 leds for 24 hours.
