@jeanna

I needed , to see many things , since i want to increase the number of turns on the pickups , by putting smaller gauge .
First see how many turns i can get in , the voltage range one way and coming back.All thing that make it better design for that special toroid.I have made the first half 22 turns bifilar , so 44 turns total, to gain voltage in the pickup coil it is also good to find the core sweet spot , the right number of turns , more works but reduce the output by 2 to 3 volt per turn , less works reduce the output.

@all

the green toroid , is a choke toroid , so High frequency, low loss ,Hi-Flux,/RF carbonyl/iron power core choke coils.

I also found those really interesting and the mention of reactor?lol

This is a quote

Toroid cores of iron powder are used as RF-inductances, pulse transformers and filter chokes for frequencies up to 200 MHz Iron powder cores have higher saturation flow density that ferrite cores

i made a little picture of my own ... 

my green toride crab doing the cap dance ...

ist

i really like his verry cool vortex eyes ... 

just a fractal of somthing bigger ....   or is that smaller?!!?!?!?     WHAT .... IT GOES BOTH WAYS ??

@ Ist and @ all
Here is my circuit for my big torid

I have now got 5 secondaries on this Big Torid (BT) (more to be wound on soon)

I wound the secondaries in parallel, because I had saved the wire I used in parallel, as it came off this torid in the first place.
This used to be the 240v feed primary.
I actually saved myself a lot of time because the turns are actually 64 turns to each secondary

I discovered by my cro, the LEDS that were between each output were sucking the juice away and distorting the waveform.
So I removed them all, except for the LED on the JT itself.

JT mod
I had to put a 1k resistor between one of the legs of the LED, as it was getting far toooo bright for my liking.

I have 1 diode to each wire of the outputs, connected AK on one wire, KA to other output wire
I found the diodes which have a .6 of a volt voltage drop, was cutting heeps out of the final output, so I bypassed them all.

All 5 secondaries are now connected in series

The output go to a 1.5v nicad, it seems to be able to charge it up, but for some reason it wont proceed past .99v
Found the cause of this.
All the diodes were loading the circuit and altering the waveforms.

OK, after removing all previous diodes and LEDs
I soldered a "Bridge" diode to the output

With a flatt Nicad connected, the voltage is at .99v and riseing.
Nicad seems to be charging and has reached 1.15v and rising

Open circuit voltage is 26v DC 
So there is a bit to play with now.

ps all, loved the leg pulling, you are a grand lot, thats for sure.

@ Jeanna
Thank you for the excellent work you did with the icon mod.
TA muchly

@ Jim:

First, I hope the fires are not getting closer to you.

Yes, I have been following John Bedini's work now for some time.  I started a Bedini motor about a year and a half ago but, never finished it for several reasons.  Mostly because I was involved in other projects but also because I could not find the components locally and was not sure what to order online anyway.  Now I have everything I need...well, except the neon which I also might have lying about.  I may have to buy more magnet wire on a larger spool as Radio Shack only sells the required gauges in small spools I which I have 3.  I have heard you can't solder the wire to make it longer as it messes up something in the bifilar coil arrangement.  So, when I get to the coil part, I may need to find a good online supplier of the two required gauges. (Unless someone tells me you can solder them, then I will just buy a few more smaller spools)

I'll bet your discovery is that, when you add multiple secondaries, the power draw goes up, but not proportionally?  Meaning, you can run a bunch of secondaries with leds, say 4, but your power draw only goes up like 1.5 from just the first one.  This is a total guess on my part.

Keep up your good work and keep your eye on the fires down there.  Be safe.

hi ,this is about soldering wire to make it longer . that is not correct . I soldered wire on my big one that is Ou  It Broke during twisting .. . Maybe that i s part of the reason . Just cover the connection up with nail polish .
