Re: HELP With Step-Down Transformer and Converter

Dear Phil,

Thanks for the tip on the Spot Welding... I will try it.
I tried using the coils from a soldering gun but I don't seem to
generate a high current... just heat.

I still need the DC-DC converter.
I know I can't have 100% efficiency ... 50% to 80% is ok.
I tried making a primary coil (lots of windings and finer wire) and a
secondary coil (fewer windings and thick copper wire) but I can't seem
to induce a high current/low voltage on the secondary wire. I know I'm
missing something ... like an interruptor perhaps?

Can you help me with the DC-DC Step down converter.

Thanks.

Gene
