@rensseak

Can it run on a single 1.5v battery or only 2 for 3 volts.

Also tesla used is toroid iron coil core has stator for motor .

this book is really great http://www.scribd.com/doc/13040608/The-Researches-of-Nikola-Tesla-1894

yes it can. the two bats are low in voltage together they are about 1.1 V and under load they have 0.9 V. i can see one of this two bats is eaven empty.

@rensseak & rensseak,

This is similar to my setups with the copper coil around a coil - but not exactly - It's actually simpler the way he is doing it.

It would be interesting to know what kind of output voltage you are getting from that in it's current form, as well as it were versus what it would be as just a twisted pair of equal length.

This is the basis of what I've been doing...relatively speaking. ...I suppose that having videos would help my cause, but I'm just too shy atp. And no youtube account consequently.

@all,

In the inner workings out our blocking oscillators - the things which ultimately turn the transistor on and off at high frequency - isn't there fly back voltage created in the coil-to-base when the transistor is turned. ...isn't this what turns the transistor off? ...creating the oscillations in the first place.

Yea, I rtfm, btw. I was just wondering why we're not also capturing that fly back as well.

@jadaro2600

the output voltage rectified and with all the LED lighting is 2.01 V and without the LEDs over 9 V.

"as well as it were versus what it would be as just a twisted pair of equal length."

mmmhh i do not anderstand you here fully

You have a toroid made of a twisted pair. If it weren't a toroid... if it were just a twisted pair.
