Most civilized civilian vehicles have 12 volt electrical systems these

days.  Much of the surplus I'd like to use aboard my all to civilized

Jeep requires 24vdc.  Building a small but mighty astable

multivibrator to handle the primary and an appropriately wound

secondary aren't a problem.  Where I do have a question or seventeen

is core material - and size, for that matter.



I know some materials are expressly for power transformers but is

there any particular reason about any material can't be used for this

application?  Frequency shouldn't be an issue but are there materials

that might not like being in the presence of the currents that will be

presented?  Aside from needing space to feed the wires through, are

there any size requirements of note?



I've read what I could find on the web.  Maybe the meds are messing me

up (They do that, you know.) but I couldn't find anything that

addressed these questions.



ANy thoughts anyone?



BEst regards,



Michael, WH7HG
