allelectronics also has a toroid that's over 3 inches across!   Jeanna did you make a JT out of carbon?

i made one with carbon but i didn't use the carbon in the way you are referring to. it was more of a parlor trick, a little spoof i tossed together to show some friends how easy it is to make something look like something it is not. it was fun seeing their faces when i showed them a working led with apparently no batteries or power input. it was activated carbon by the way, the kind you find in fish tank filters, i'm not sure if that would work so well for a core. ironically that is part of what i convinced them the carbon was for, that it needed to be there. the 'all important', 'will not suck the vacuum without it' QHC (quantum/hydro/carbon) spark gap

Thank you for the reply, they are had to get around here so far...for me anyway.

I had an idea to use conductive nanocarbon with a JT but I wanted to see if anybody has tried to make a carbon rod JT and if the results workable.  I was interested  to see if carbon resonated in a similar way to ferrite.

i'll look in my aquarium junk box and see if i have some carbon from the old freshwater days. if i find some some i figure i'll crush it and stuff a section of drinking straw to made a 'rod'. don't know when i'll get to it, i'm trying to figure this anomaly i'm having with a certain li-ion battery that runs my fluoro tube twice as bright as the others, so someone please beat me to it.

can you scavenge a carbon rod from an old battery? messy but if they are hard to get where you are it might be the best route.

@ Wilby:

Thank you for your comment and again for the drinking bird suggestion.  I just received notification that it was shipped today.  This will be fun.  My friends that see this at my place will now know I am nuts, ha ha.  If it works at all, I, of course, will make some videos.  Thanks again.
