Electrical Demagnetizer

Hi all
Iread this thread 2 days ago and thought "what a good idea".
yesterday my neighbour said to me " my microwave oven just packed up, would you like it for the bits inside "
"not arf" says me :D
so here's my version,
inside
and outside
the box cost a couple of quid in B&Q
the rest was lying around, as it does :lol:
the coil is held down with cable ties. works a treat.
cheers

Bernd:
Hey nice Roy.
Ah Mad Jack I've got to give one of these :wack:
Go back and look at my OP. Notice that I use the coil with the finer wire, not the whole transformer. I remove the secondary coil and use it be itself. I was just showing what that transformer looks like when removed from the micro wave oven.
Remember the magnets in the magnetron are also good items to save.
Bernd
wheeltapper:
Yea, I got the magnets out as well.
thinking about it, I make something to DEmagnetise things then save 2 ruddy great magnets.
I must be mad.
incidently, if you have a mechanical wristwatch, TAKE IT OFF before switching this gadget on!!
cheers

Ah Bernd, using just the secondary means you get to use the transformer without a core, and with enough impedence as to prevent buring up the coil. I save those microwave transformers in case I need to hurt someone someday, you can never be too paranoid, and they are out to get you!! Properly used, that transformer, the magnetron, and some artful wiring to an inverter and you've got a radar gun disruptor and probably disrupting all sorts of microwave communications, and maybe even wireless computers. Might be valuable to keep around. Mad Jack P.S. I think I got my fan motor with the "shaded poles" off the same microwave, don't throw anything away, that's my motto! Be Prepared!
Bernd:
Hey Mad Jack. Sounds like my kind of thinking on the transformer. That would be an interesting project. :dremel:
