ok here is the weird bifilar / secondary setup on a large black toroid with a know Value given to me by Greg for EB research . the number is visible . Its low perm high flux . I am getting over 1900 volts . this setup Takes the Tv out . Im on satellite and the tv is about 8 feet away .The Voltage is fluctuating as i get near the setup .I need to Box this one .. using tip121 50x2 primary CW 108 secondary (green) ccw . I tried this on two meters one ol'ed on the 750 volt scale . this one is set on the higest setting 300+ and the meter can measure 2000 volts before it Ol's

Incredible Gadget, is there a site we can get these toroid's from?

@xee2
I apologise for missing your post to me.

@ electricme

To get more vots out just add more turns to the pickup coil and/or reduce base resistor value. However, there is a lower limit to base resistor value after which the voltage starts to decrease.

I agree with you xee, but depending on your particular coil, will depend on the results you get with it.
I have found every coil I have made is hobsons choice.

I miss 1 day and there is heeps to catch up on, phew.

Diode limitations

@electricme

Don't forget to test other diodes ! those are 400 volt you may have more then that !

Mark

Thanks Mark, I have been on the net looking for a number of diodes with higher ratings, the 1n4004 is at 400volts, so next thing is to make a bridge diode from 1N4007's and see how that goes.

I think I may have stumbled on why both of you have not been getting results with Hazens1 HV toroid

Bill Great Going . I figured a super cap would run all that stuff . Now i guess i need to make us a Flip Flopper to file from the dead cap to a Charged one . This only applies to the little suoer caps . the ULTRA cap will run them for days on end . I now have several Monster 650 farad caps that run jts for 4 days . I have also built a regulator to carry the 2.7 volts down to 1.6 to run fugi stuff. I am a little disapointed at my hazens replication because this would have been refined by me to the least amount of input but that ain't the problem . it just dont work with the amount of turns on the primary Jt . Now the LPJT has 100 turns primary center tapped and works on a lot of different toroids . I might hook this one up backwards and see what it does

@electricme . I love Australia !! your too cool man .
@ mark . Less? ok ill go 3 x3 and see !!

I took my Hazens1 into Dalby, and accidently left my good Red $80 DMM back at my place, but I had a run of the mill el-cheepo $15 DMM with me.
I connected up the battery and the DMM and it read very low low voltage, then I thought about the trouble you both had trying to see any voltage on your own DMMs.

Is there any chance that some DMMs just carn't read certain JT configurations, even if they are working?
When I return home tomorrow, Im going to test this quick smart and report what I find.

@Gadget,
Is there any chance you will return to Ausie? even if for a holiday?
Everybody is welcome to come to the Land Down Under, we all upside down anyway he he.

Its pulsed Dc because i am not rectifying fullwave bridge . Its a little different than what electricme described in the output stage . On the Ac scale it sholde be about 2600 volts ? . I spose i could light up a bunch of Christmas treelights in the house and out in the yard ? Mainily i wanted enuff to light CFLS but i believe more light  from leds . I just got 100  200000 5mm 20ma white leds and they are brighest i have ever seen . one will light up a room if delineated with some translucent plastic . so 1000 to 3000 should light the whole house on one of these babys . I am using a cell i tor out of an oldder laptop battery and they charge up to 1.4 volts and 4500mah . the one im using now i havent charged in 2 days and its been testing  around the clock . I got an old altoids light wanna see it runs 24 hours a day 7 days a week and hurts your eyes . the led is a 1 watt luxeon i ripped out of a light . I put it either on top of an overhead CFL and when i shut the cfl off i still have light. If its bright outside i set in on the window sill . runs for 50 hours on a 5 hour light charge .
and here is another old bedini using lagr speaker and nedium magnet flywheel  with a small coil charging a jt battery and lighting up  twin eye balls. the bright shot is all jt light no flash . Of course this thing is spinning at 3000 +rpm and charging up 10 other batterys also .

200,000mcd is very bright but the brightest I have seen are from goldmine 265,000mcd 10mm but they are 3.25 per led

That could get expensive quick!
