Joule Thief

@ Pirate88179

If I can run it, my question is....if hooked up to a 48" tube, will the tube be like really bright at 2,000 volts?  And, if I add their other circuit, what would happen if I tried to light the tube with 25,000 volts?

The spec says it will output 2000 volts at 10 ma. That is 20 watts. I would think that 20 watts at 2000 volts into a 20 watt tube would be full brightness.

I have run 4 watt tube at 14,000 volts from a 1.5 volt AA @ 248 ma (about same input power as Fuji) and it is brighter than Fuji circuit but not a lot brighter. So I think just increasing voltage will not provide big increase in brightness. Once tube lights, the voltage across it is set by current through tube. The high voltage is only needed to start the tube.

@ Xee2:

Thanks.

It ended up costing $65, with shipping $52.95 +12.00 I think. I think it was well worth it because I was stuck. It helped to unstick me.!

I better find out what a hendershot motor is. I haven't made a bedini motor yet.

BTW I believe your results have to do with lack of ferrite core. It shows up on that meter as amazing.
Even iron is lousy next to ferrite, but as you will see with stubblefield (Yeay another person interested in stubblefield!) you can use soft iron.
If you really do not want to use ferrite, perhaps you could try an iron wire.
I got some black annealed iron wire at my hardware store when I made my stubblefield coils, and it shows a stronger inductance on the meter than air but still much less than ferrite.
You can also use a spool of tie wire for rebar. It comes in a spool about 4" diameter.

It would be interesting to see your big set up made with part or all iron wire for the core.  I would be very curious to see this.

@forestWhat is that?
Maybe xee2 did, if it means joining the secondary to the battery?
I better just wait for your answer.
thank you,

I meant about connecting somehow output of joule thief to the input, basically to create self-powering device

Hello . Everyone . Not much to post excvept i am way behind on the threads . i think somewhere in the 800's is the last pages i read . the reason is i am on Dialup now . My high speed internet from my Cell phone was Alltel and they sold out to Verizon and they want to charge me 80 more dollars on top of the 89 i allready pay so good by Data on my moto Q . It take 10 to 20 minuits for one page to load on this site . I will never catch up on reading because i don't have but maybe an hour a day for the computer Due to My Daughters School and other commitments . I  can't even update my Web Sites . Takes DAYS and DAYS to upload to it . So . If anyone has asked me a question in the last month and a half and you have it between 800 to this page please by all means ask again or message me . DIAL UP SUCKS !!. Also i Noticed Stephan removed all the Signatures from uses including me . I run www.sunpowerwindpower.com and have a lot of good stuff folks use here so if you need any parts n stuff please use My site . i wish you all happy sucess with your experiments as i have . What i learned and Shared has made free Energy a reality . So far i have several self running Jts .Jt hho generator  Bedini that run themselves replicated by a few and My patent pending E-light . Wish i could spend more time showing you how i Figured it out but the Connection speed won't permit it so this is goodbye until they run DSL where i live . a lousy two mile stretch that they forgot about when they put DSL on both sides . 

Luv you guys .
