The coil in the middle is only connected to the red led .

The coil in circumference is indeed the pickup coil , the one in the middle (satellite coil ) could in some way be called a pickup coil.

The coil is on a bigger tube , the diameter is slightly bigger then one duct tape roll.


The tube is divided at 36 degree , so to coil X both starting form the outside going in at the bottom of 5 turns 16 layers total 2x80. ( 16 layer pancake )

Yeah. It sure seems to. You make such nice looking coils but you get such strange measurements. I suspect it is working at a pretty high frequency. When you rectify it, do you use a cap on the output of the rectifier (between plus and minus out) and do you measure the voltage across the cap with the meter set to DC input?

The bridge was connected right , and the meter was on Dc , the only cap i connected to it was one electrolytic cap 470mf , it started filling it self at 2.5v increments until i got to about 10 volts , then slowed down to about .2 v increments .

I usually see something on my meter really not with this one.

It dose work on the leds but not powerful like the one lighting the bulbs.

So to me it sounds like you are putting out about 10 volts. If you are filling a 470 uF cap in less than a minute then you are putting out a fair amount of current. Have you tried tuning the base resistor yet?

I get usable power for 0 ohm to about 1.5 k .

I also redid it and now both winding are parallel and i dose give a reading now and is about 11 volts . And time wise less the 30 sec , not that impressive to me anyway.

Thanks Mark,
So, the first layer has 2 wires but they follow the path of one another, then the second layer does the same thing with the 2 wires, but in the opposite direction... 16 layers.
Is this right?
It seems I don't understand.

Wow, so the red led is shining from pure radiant? wow wow.

And those white leds. Are they wired to the fat outside secondary pickup? Or are they at the C-E at the normal jtcl

amazing.
And there is no warmth in the wires of the coil?

not that impressive to me anyway.

but it is scalable and no toroid.
A bedini motor is best with over 600 turns.

what is the amps draw?
