Greetings,
Does anybody know what the geometry of the core is in a electric
toothbrush charger? I have an electric toothbrush that charges when
it is in the cradle.
I would like to use a similar design for charging handheld radios for
our troops. There are problems with salt water getting into battery
packs and corroding contacts and so on.
I am mulling over running a MHZ or better sinewaves through the
interface. I was thinking probably a sheilded ferrite half cup on
each side of the interface should do it. I was wondering what effect
the gap would have .
regards,
Bob
