Joule Thief

@hazens

Nice work there , you may want to try them in parallel , they should be brighter , but you did show high voltage there.

@artic knight

A transformer doesn't work on dc, you need ac to make the voltage jump from the primary to secondary.
The transistor is needed for creating the kick.

@jeanna
Nice work , i always thought that the voltage would be higher at a faster freq, well it seems i was wrong.
Its a good thing that you are sharing those valuable info , keep the good work.

On the pure ac , it looks like a perfect wave but in ac the 0v is in the middle of the wave, i think on the jt the wave is a bit offset.But it dose look real nice tho.

Edit . I have found a real nice book on Tesla's work

There are more details then in the patents.

Great work and great proformance on your coil.  Thanks for the link to the leds

when a paper contain more occult and suppression theories then provable scientific faqs, i call it a novel...

Nice work man..

@all

What is the pros and cons to hooking up led's in series or paralell. I have been thinking of hooking mine up in series.. for my hula hoops. But i dont know if it is a good idea. If one goes they all go out.correct.

@MK1

yes the magnetic current has to change to induce a current but can 2 coils alone turn each other off and cause a pulsing dc current? this i shall test.

@ all

could someone be so kind as to test this basic joule setup and tell me what the output is on the osciliscope? if i could get a picture of it that would be fantasic and greatly appreciated! im looking to see what the voltage out is, what its pattern is, even its frequency. im also looking to see if it drops back to 0v output between cycles. this setup is using the standard torrid with the transistor and a small capacitor. the output reading that im curious about comes from the return path to the battery.

if anyone is able to do this quick test for me i would be most grateful for the data!
