Pulsed DC Transformer with Embedded Magnets

[Paul-R]

My problem at the moment is to find easy ways to do the LCR tuning.

I remqain of the view that grid dip oscillators may be for this. Here are a couple
of circuits deliberately designed for megahertz operation.

Can someone adapt them for a frequency range likely to be useful?

The first one is the simplest of the two. It has already the info to get the hertz you want. Just follow the table.

But in general, they both are too complicated for us newbies.

Also EBay list a few turn key solutions.    A variety of Dip Meters. 

Minde    Thank you for the HHO comment.  Found 2 glass LENSED and 3 HOLES in bottoms each from factory at a yard sell.  These holes are aligned so each half make together a 8 inch pie sized glass cylinder with a very level matting surface.   This glass is from the 1950's and was made for flame safe heat (Chafing dish warmers).  So total I would say it is just over a gallon area inside.   I think the lensing effect may be fun to examine and even can be made to benefit the HHO production if we're lucky.

I dont understand what you are doing!

Hope the attached figure makes things clear.  It is a simple but effective technique.  Try it.  You are almost guaranteed to get much higher overunity COP results!
