@all

Thank for all the positive feedback!

Think of this like a mk1 with 4 pickup coils , the positive of one coil set feeding the the other in perfect sync.

Mark:

Not to sound stupid but are there 4 pick-up coils there? Or just primary and secondary?  I am still learning on how to read electronic schematics so if the answer is there plain in front of me and I don't see it, that is why.  I will build this as soon as the rest of my parts arrive. Thank you.

@jim,
This is such terrible news.
I know Australian firefighters have helped in the Northwest more than once since I have lived here. Once in California and once again in Washington. Sharing help worldwide. It is the way it always should be. Bless all

@Bill,
Yes, actually the first 2 are the ones I was thinking of. They are big and sharp and UNmodified makes it clearer exactly what to do. Hopefully folks who have not ID'd themselves here yet, will be able to make little bright units for rooms in their homes.

@Gadgetmall, does this sound good to you?  I also would like a clear shot of the way you made the switch for the high voltage hit to start it up when a little gone.

@ Slayer
I'm on it slayer,
I will see how many I can pack in, now I know which core to use

Thanks so much.
Everybody!
Wow, when you step back and see the contribution. This is awesome!

@ Jim:

Thanks.  I now have 50 of them on order. (along with a bunch of other fun stuff)

Yes, I have been hearing about the fires down there a lot on the news.  They still don't say if they were set, or accidents?  I hope they are not getting close to your location there.  If it looks like they might...get the hell out.  Be smart and maybe head to the coast.  Take care of yourself Jim.  I am sure the US is offering whatever help we can provide.  Australia is our friend.  Please be careful.
