broli:

That looks like a nice project.

But man, did you see he is powering it with 12 volts?  Do you know how many 48" tubes you can light with 12 volts using a JT?  A lot more than the one he is lighting that is for sure. (I can light two 48" tubes on 1.5 volts)

My guess is that the Jeanna Light circuit is much more efficient, and maybe even just as easy to make.

so now off of my 12 volt cap stage 2 unit i see no reason i can not plugg this ring into a 75watt 12vdc to 120vac invertor a 15$ unit put a bridge after the 120 vac so its back to 60hzdc  but 120v on the input ... and power 1000w worth of light ..  and still have ....   many amp at 12vdc ....  as it only uses 75 watt for that invertor when you use the bridge you have a 120vdc jt... transformer...  the colapse goes out with the inputted... 

all this from a power can a stage 2 unit and 1 convertor ring and you still have 12vdc 1000amp continous all the time ... 

from 5 1000th per charge cycle to start stage 2 ..... 

see where all my work goes ...  wonderland...

HIGH VOLT FROM 12VDC  500PLUS VOLTS AC  A FEW AMPS ..  12VDC SUPPLY CONVERTOR RING
ITS JUST THE KNOWOLAGE OF THE COILS AND HOW THEY INTERACT!

Here is how you can make cheaply yourself a few supercaps:

They light read and yellow LEDs very nicely for a long time,
if you make them BIG !
;)

lol mr mag  ;D get the wabbit.

Yes, broli,
But if you want some help  I/we are and have been willing to give it.

Please just whenever you get started let us know if you have any problems.
It seems incomprehensible at first, I know, but that is the reason I recommend the makezine video because a video is worth 100,000 words, if you kwim.

Before this thread, I made 3 of these and I would have it all booted up and I put the pieces together and just did one step at a time then advanced the video.
I couldn't do any better myself, which is the reason I don't make a video.

And when you are ready to turn the secondary it will be the second time around, and therefore easier.
Maybe I can make a video for that??

Allright . Thank you for that information. This could one day become useful is they stop selling these high power Bcaps .Hey i'll try this and make one the size of a 5 gallon bucket with a half inch carbon rod for the electrode/ 20,000 farads maybe ? probably not .still a nice project for a winters day.

Hi Albert, as we don´t need big currents to power LEDs,
just spare your money and just only use small pencil electrode connections.
Big sized diameter graphite rods are pretty expensive.

You better need to make yourself much more conductive graphite powder
from coal briquets, which my girlfriend found out accidently..

See here:

http://www.overunity.com/index.php?topic=790

Then if you made a few supercaps this way, better put them all in series to raise the
voltage and then put a few LEDs in series also as the load, so this will last much longer this way,
as the lower the discharge current is that you draw from the supercaps, the bigger the capacity will
be and the longer they will last and keep their charge...
So better put many in series and use only low discharge currents.

Hope this helps.

P.S. If you put 10 supercaps in series, which are each fully charged at around 2,5 Volts each,
you already have 25 Volts output voltage.

If you then draw only 20 milliamps and use a load of 8 to 10 white LEDs in series,
which have a threshold voltage also of around 2.5 Volts, this
will last very long to light them up.

This is true Stefan, but I would assume for the OU test, the capacitors will not be starting fully charged. If this was indeed allowed, anyone could win the prize just by using a large enough fully-charged capacitor powering a resistor which is dissipating 1W for 3 months.

Then again, maybe you weren't alluding to the OU prize and were just commenting.

Well, no my last 2 comments were only made how to
best build yourself a few supercaps and power a few LED lights in series,
if you have for instance charged up the series supercaps stack with a solar
panel during the day and use the LED light during the night for independant
grid free light output.

Regarding using supercaps here in the Joule thief, if would also be beneficial
to use more than 1 supercap all put in series, so the JT can charge them up
to higher voltages and higher voltage means also more output power at
the same small load output current.

Hi Stephan No i can get them very cheap actually directly from the manufacture .  . i have many already for earth batteries . pencils are expensive here :) but i will try it ! also i could substitute paper towels for maybe shamwows. i have acces to barrels of graphite ,carbonize filter  products  and powder chromium  .thank you .

Well, normal supercaps have a limit charge voltage of around 2.7 Volts.
You should not charge them up higher, as they could then go boom.  ;D

With the alufoil-graphite supercaps, you could go still about 0.7 Volts higher,
as the galvanic dissimular metal effect adds 0.7 Volts,
but I would recommend not to charge them up over 2.5 Volts, so the
alufoil will not get destroyed.

Maybe we will still also find a better electrolyte than NaCl saltwater solution.
The solution should also be not too concentrated, otherwise the alufoil
will decompose after a while.

Also it could be much easier to use graphite paper as the graphite
layer, so just use an acryl binder with water to put the graphite powder into
a solid flat paper like shape and already put the pencil graphite rod
into it before drying, so the pencil graphite rod electrical electrode connector
will already be "glued" this
way into the "graphite paper" and must not be fixed later.

But you must roll up then the stack already before the acrylic binder
has dried, otherwise it will be hard to roll the stiff graphite paper later
after it has dried up...

Hope this helps.

yes actually it did give me an idea . Might work might not . I have rolls of aluminum flashing to use and some brown paper bags and bake it in an oven  a graphite mixture on it . Well we will see . mixture is another thing  i can research . there are a few milliliters of highly posionious substance  in My ultralcap i did forget the name in a maxwell ultracap as the electrolyte so maybe there is a substitute for NaCl saltwater .
Have a good day or night  its 1:39 am here .
Also if you celebrate Thanksgiving in Germany . Happy thanks Giving

Stefan:

This sounds like a nice  project.  With all of the smart and inventive minds here there is no telling how far this could be taken.  I look forward to seeing some results over on your topic.  Thanks for telling us this.
