yep wild toys .. 

i just finished a bigger unit on a 1.25 " toroide ..   3 phase jt 5 turn with 50 turn generator windings 26 gage 100"

i will add mk2 pick up coils ...  what is the proper name for those coils..  i did find some on a toroide inside a microwave that is 20 years old...  lol   i dont know the proper name of the winding

then like i have been saying years ...  there is 1000 ways this still could work ... 

ill put the pick ups on it then take a picture

why the hell do you all think this needs to spinn supper fast ?!?!?!

Finally just what we need for west nile! hehe nice find!

This guy must have really hated bugs!

I think I should not have used the mag wire.
I had frequencies higher than 250khz.
I am getting used to such numbers, and it is certainly in the very high frequency level.
Just because there is higher, it doesn't mean this is low.

OK I have some cat5 cable and some RS wrapping wire which is covered in 'kynar', a rubbery white substance which might be gutta. It is 30 gauge wire and hard to strip without breaking, but if I am careful I may get the results I want.

I am thinking I will wrap the whole thing as the pickup then add the dblxx primary over this.

thank you,

Sorry for the delay in posting my results.  I wound an entire side backwards and then got crap for results.  I needed to step away for a while but here is half the tesla idea results 

It pushing a little over 350vdc rectified with little tuning and messing with. 52 winds each side off the pickup and 10 on the collector coil/2 on the base!

32.2 Ohms off my 500 Ohm POT

2N3005 power transistor

Not too bad for half an idea hopefully adding the other side will help and not hinder

I got a idea last night , what if we used a led chaser circuit to pulse the jt coil , first the over all energy sent in the coil will be far greater then what we used today on the jt coil , second it will be easier to test other coil configuration , also they are set to chase them self making it easier to have a real rotating field , the speed can be adjusted like on the regular jt , the pulse is a square wave this will make a stronger kick , so we should get a better output .

Ok it work on 3 v with 10 led, and its rated for 8 month of work on AA , and 4.9 years on D, humm , if we get half of the half of that it still would be great ...

I will make some tries today , i got one bike led light from rama , with chasing mode 3 led so i will try 3 pulses per cycle , on the down side i can't control the speed but there is two preset slow and fast , but not ultra fast .

i wish i could modify this circuit but there are no parts , 6 led and a switch the rest is in a small whit dot ...

Also great for tpu type stuff ...
