@ IST:

Thanks man!!!  That is a great video!  You are correct in that it demonstrated exactly what I read last night.  The ring with the cut in it reacted much differently did it not?  Again, this may or may not be useful to us....I really don't know.

I hope I live long enough to wind half as many cores as I have seen you wind here in the past few weeks.  Your work is awesome, please keep it up and keep sharing.  Thank you so much for your contributions to our topic here.

@ Bill
Cutting a slott in a torid, I realise you have vast experience with cutting tools, however, would this work for you.

Make a ultra thin disk from a empty tin of baby food (eat the contents first yum), (remember the hot transister fix?)lol,
use a hole punch to make the disk from the lid, make the center hole by drill.

Mount it in a dremmel or high speed drill

Make up some rouge - water to be a lite grinding paste, then spin up the disk, feed the special past and see if it will grind a thin slott in the torid.

One can cut glass using this method.

Dont get your fingers close to the spinning disk, it will taker your fingers right off.

@jim, this xo laptop thought your movie belonged to the sonic measuring program. I don't know how to tell it what program to open it in. I will watch your tiny video this weekend after my MAC gets back home.

Did you eventually get to see it?

@ all
Ive been cought up in household chores all last and this week, a never ending battle.
Been experimenting with a home made coil, Wound it on a empty solder plastic spool 500Gm.
l, wound one layer, go to the end, took the wire back to the beginning, and started the second layer. Did the same with all 8 layers.
Had to use copper, havent got iron insulated wire yet.

I am a little confused here with the new toroid windings.

@electricme

It is nice to see you again.

@gadgetmall
I could not get all the schematics out of post.
I will bother you no more with my insistence.

    I have Not had Time today to look at all the Post  YET But I want TO INFORM you That I have REDUCED The CURRENT DRAW ON THE FUGI BOARD TO  0.20 MA  This was ON MY BOARD 1900 Ma .  . There Is a 220 ohm resistor on the base I replaced it with a small 10k pot and added a cap on the circuit across the last leg of resistor to coil . It lights My 15 watt CLF Bright with ONLY 20 ma .. I am Running it now timing it with a 1.2 volt Ni cad ..see ya Later .!!! Here are the pics . Sorry about the Blur . Ill fix it later gotta run . Its School Award Time this Morn !!
