                 By the third time you play this TINY video,
                            you will JUMP with fright.

                            Faster than a bunjie cord
               Is lightning faster than a sprung mouse trap?

I had i strange idea tonight,
well its 6 am now but there it is.I was looking at a alternator schematic and got the idea of making one on a toroid, to test delta and star wiring , It will need a picture but let me tell you about it anyway ,i have created 6 divided parts on the toroid 3 per wire in a double triangle shape one up , one down (each space are 5 turns) and i added 6 pickup coil (all14 turns) covering 3 parts of the toroid each. Those 6 pickup coil gives me a steady 22 volts each , now i will be able to wire 3 in a delta and rectify and the other in star and rectify to see witch i prefer.

I may have some real ac in there since each 6 parts are wired in opposite poles and falling to ground. I really need a scope.

The regular 2n3904 , 1 k .

More later , i am not sure if that is right , i got to go to bed , lol

Edit : @Pirate 

nice video

@Electricme 

nice design i will try it !

@jeanna 

2 jt in series you really need to change the resistor , it cost in run time.

@Jeanna
That is so Interesting what you are doing . I made a new toroid with 11 turns two wires . and tried the one turn thing . I have a bunch of red leds with wires already on them 4 inches long . you don't even need to wrap them at all just stick one lead thru the hole ,polarized and they light up with no noticeable loss of input current /volts or brightness . Much more light/ns current than running them the normal way off the collector emmiter . Fascinating !. Also tried the 11 turn toroid with the earthbattery . it will not light at all . the earth battery will run a jt with a smaller toroid with 20 turns+ the normal way but will not light one turn leds .
@electricme
funny . any bets that the peanut butter will get em first

didn't you  say  at one time that you can achieve OU by  driving a ciol with a PWM ?


If  we  made a T  connection   to the output  of  a JT   and  put a diode on each  end of the T couldn't  we feed  a half  cycle to 2 different coils?

That's the setup for a Schottky diode, I think. Hook the coils to the outer two and the jt to the center  Isn't their deal that they have a low resistence?

I think you will enjoy my latest video.  You can view it here: http://www.youtube.com/watch?v=27QJ92ruzeE

What I did this time was to wire 2 Fuji AA circuits in parallel but, I only used 1 battery!!!  I lit a 48" tube and you can see in the video how bright it gets when I switch on the 2nd circuit.  I think this is significant and it is telling us something.  Please look at this and tell me what you think.  I believe this will directly apply to our toroid circuits as well.  Thank you.

I did a four joule thieves parallel circuit that worked on one 1.5v battery. There was three different transformers and one of the parallel circuits was with an inductor. So I belive that you could make a parallel circuit with four camera circuits with just one 1.5v battery. If it work. We will see the whole worktable you use when the lights are off.

I could be wrong though.

This is the best thread from this forum for me!
