ill go have a look ...  thanks mark


here is a pic of the ring ...  i might just try a microwave magnet tho and use 1 of those ac rings to drive it ....  sheesh lots to do



i wouldnt have it any other way tho ...

i also have thos bobbins from the sewing machine unit all ready wound .. looks like i can slide them right on the ring  might speed up my tests ....



ist

bobbins dont fit close but not close enough ....     so ill wind something small see what is the result!

nope does not look good ...  done done on to the next one ...

mk2 hv  80 turn ....  1"   what kind of toroide did you use mark ?

what colour i have a few  ill likely just use the black i found 5 or 6 turns to work well for those ...

@ist

I got 24 bright led for 2 buck at rama .....

I also have to say that i get 850 volts dc from 80 turns , on my one inch toroid.

Mark

80 turns total or 80up then 80 down making 160total?

@stprue

On the mk hv there is 80 turns per secondaries , on this one i am not going up and down.
It may be the reason for its success...

@ stprue

I do not have any photos. Sorry. Perhaps gadgetmall does.

EDIT: I will make a drawing.

Ok thanks anyway.  I have been wanting to try a voltage multiplier on my biggo but I'm to slow to figure it out for some reason!
