Jeanna’s Light
This is a modified version of Jeanna's Joule Thief FL driver circuit using a big 31/4" toroid coil. The circuit is running on one AA 1.5 volt battery. A modified 10 watt CFL bulb is being illuminated. The circuit shown in the video has an error in it. There is no connection between the transistor base and the circuit negative rail. A 100pf capacitor can be placed there and Jeanna used one. I just eliminated it and got the circuit to run with one less part. Information on her circuit can be found at the Energetic forum under the "Big Joule Thief" thread.

Le transistor de puissance du type NPN bien connu du type 2N30555 ne pourra
pas fonctionner sur le schéma présenté ci-dessus car sa base est au même
potentiel que l’émetteur. Alors, ou il y a une erreur sur le schéma ou
alors ce montage n’a jamais fonctionné!
could this be possible to light a 120v incandescent?
+Chris Smith (porscheflat) No. Not enough amperage.
im confused u said the bulb was drawing about 100 ma but that wouldnt be
possible considering u said the input of the transformer is that much. so
output is probably like 10 ma
Jeanna seems pretty smart !! Is she married ??
I think so.
Nice work I like the large toroid for joule thief myself it is easy to
wind. You might like a 2 transistor push pull oscillator shown here it has
more current than one transistor and is up to 84% efficient will work at
1.25 vdc @ 40 ma to 14 vdc @ 2.2 amps over 800 ma at 32 vdc output that’s
25 watts. the transformer is no harder to wind than a standard joule thief
Give It a Try !! Tony
jeann please send me step by step how to build morgan from nigeria

base and emitter connected???
+andreiruiz143 No. If you check on second 06, he corrected that error.
Circuit ERROR.– No connection between base and neg. rail.
Hi Lidmotor. What is the voltage you’re getting at the CFL? What
modification did you make to the CFL. Where did you find the large toroid
core?
Thank you.
Простой повышающий преобразователь !Тесла давно всё объяснил !
Nicely done. :-). I recently got my hands on a bunch of toroids and made
this circuit, but a slightly modified version using a much smaller toroid.
The results were excellent. Check out the video!

kkkkkkkkkkkkkkkk
this isn’t wireless is it? the 300 turns are wired to the tube?
It’s a pretty wild circuit. I’d like to see a scope on it or a simulation.
Does the transistor get very hot? I wonder what percentage of power is lost
in it.
If you replace the CFL lamp with your finger you might experience some
pain. This would be due to the “microwaving” effect on your finger. That
battery could give as much as one watt.
Shhhh…lidmotor. shh……. thats a secret ! Lol.
thanks a lot i made it….
This circuit actually puts out high voltage pulsed DC not AC. The gutted
CFL (no circuit inside) runs quite nicely on it.
Do you know BlackTiger?

could it be done with smaller toroid and more windings?
Rusty, hard to believe this was way back in 2009, ha ha. It is still a good
circuit and a great video.

Nice! Would you mind posting the circuit diagram? :)
The circuit diagram is in the video.
