ss tesla w/ ignition coil

[kooler]

i just noticed yesterday one of my friends asked me what kind of wire i was using on my big toroids.. in my old videos. like this one..
YouTube - joule thief w/3rd stage

i told him it was litz on the primany.. i told him i had a whole spool if he needed any..
he told me that he had one of those 3.38 '' toroids and tried the same setup but it didn't do near as good as mine .. so i give him a 1 meter of the litz i had and he called me a hour ago and said.. i know your secret.. he said w/out the litz the circuit draw 282 ma's and had a lower output..
and w/ the litz it drawed 108 ma's with a very much better output..
his toroid has the same 22awg wire for secondary and turns mine had 180 turns and his did too..
and he said that there was over 300 volt gain from using the litz for the primany according to his scope shot , he said the wave form was also more ramped than spike like the regular joule thief..
just thought i throw that out there..

Sparks

Hi Xee2 I saw your videos and wanted to tell you that I had read once that sparks emit X rays don't know if this is true or not maybe you can enlight me.
Thanks

In order to produce xrays, very high speed electrons need to hit a metal target. I do not think this is happening in the Jacob ladders. BUT - sparks do emit strong ultraviolet light that can harm your eyes. So do not spend a lot of time looking at the sparks unless you use glasses that filter out the UV.

I put a flyback (not Goldmine) and circuit in a box and now I have a high voltage power supply.

is the 1.5v putting out 5kv at 160 ma's
is it the same circuit we started with

cause that is very good output for the input..
i might have to go thru my flybacks and play with each one..
i got 17 different ones i have pulled from crt's

awesome performance you got there..

Same circuit. 1.5 volts in at 160 mA in gives 5 KV out. The flyback is from a Samsung color TV. I plan to use it mostly with 6 volts in. I would like to replicate some of the JNL antigravity experiments.

This makes small sparks (about 0.1 inch).

Lighting xenon tube with 1 AA battery (in cell phone charger) using Goldmne flyback.

YouTube - 1 AA xenon

EDIT: Xenon tube will also light if the diode and capacitor are removed from circuit.
EDIT 2: This video has been removed. See the new video with same name below. New circuit lights xenon tube from 1 AA without the cell phone charger.

looks like good results..
the cell phone charger i have is worthless..
i check the draw on the output like everyone else.. and it will show 55 ma..
but if i check it on the battery going to the unit it will show a 188 ma.. draw..
i had the hv transformer from goldmine running at 65 ma's on my cell charger.. with awesome results but once i checked on the battery it was 254 ma's.. so i don't use the charger on anything .. it is one of the cell chargers from goldmine.. i should have bought a better brand.. i reckon..

Thats a great result xee!

Looks like mine does when i use a new 9V battery

Im gonna try your circuit next.......

Scope shots. Note, my scope is too slow to catch the collector spikes.

@ kooler

My assumption has been that the diode was helping the transistor turn off quickly. However, with larger capacitor values the diode does not even turn on. So removing it from the circuit will not change circuit performance when using capacitors larger than about 1 uF. It probably is not helping even with the smaller capacitors, but it does turn on with small capacitors as shown in my previous post. The real improvement over a standard Joule thief seems to be the location of the capacitor and resistor.

@ kooler

This circuit provides increased current output at expense of output voltage (with less input current). It should charge capacitors faster and make CFLs brighter.

i noticed awhile back that at certain freq or some coils that the diode and cap are not needed..
i like the the ideal of the cap from the neg to resistor.. i going to try that soon.. thanks

This circuit lights a xenon tube from 1 AA battery without a cell phone charger. It will also light the xenon tube without the 10 uF capacitor. Thus it seems that the key to the improved circuit performance over a standard Joule thief is the location of the reistor. Although the Jacob ladders work better with the capacitor, so it does help some.
