    Bigginers Handbook

    The title of the book is "Getting Started in Electronics" by Forrest M. Mims.  I own the book and I think it is probably what got me started in electronics.  I would be glad to host it so everyone can get a copy of it, but I am slightly worried about copyright law.  Perhaps if I put it in a zip...

    High Voltage Cap charger

    You may want to look into using a "boost converter".  That way you only need an inductor and dont have to make a 900v transformer.

    Transformers

    Well, I can see your reasoning, but it is very hard to actually make this work.  The problem you run into is that the second transfromers sees many more volts per turn than it was desiged for.  This causes two problems: overheating in the windings due to overcurrent, and the biggest problem...

    battery charger

    The caps around the regulator are just to help filter out noise and are really not needed at all.  If you still feel a need to put then in, basicaly any small caps will do.  The section you are talking about uses a 7805 voltage regulator to create a constant current source, so the current should...

    Microwave transformer

    The output of a MOT is taken between the core and the only one connector on the secondary coil. There will also be a low voltage winding of a few turns of fairly big wire. This can be removed as it is likely useless. You will not be able to ge 4.2kv out of a single MOT. To do that you need a...
